Different estimates:

The length of the radius of a cylindrical pipe:

Plumber W:

Radius had a length: 3/5 inches.

Plumber X:

Radius had a length: sqrt(3/11) inches.

Plumber Y:

Radius had a length of 9/100 inches.

Plumber Z:

Radius had a length of 3/14/24 inches.

Turn them into decimals:

We can turn each length into decimal:

Plumber W: 3/5 = 0.6.

Plumber X: sqrt(3/11) = 0.522222..

Plumber Y: 9/100 = 0.09

Plumber Z: 3.14/24 = 0.13083

The list from the greatest to least:

We can order this list taking into account the following reasoning: when the number is near to zero, this number is less than the other in the list. Examples: 0.001, 0.0002, 0.00004 are very near to zero.

Additionally, when a number is near 1 (the unit), this number is greater than the other less near to 1.

Examples: 0.69, 0.73, 0.888, 0.99 are near to zero.

The numbers we got in the list are decimals numbers coming from fractions and the square root was taken to the estimation of plumber X. Therefore:

From list 0.6, 0.52222..., 0.09, 0.13083

The number nearest to zero is 0.09. Then, 0.13083 is greater than 0.09 but less than the others. The following number is 0.5222..., and the greatest is 0.6.

The list that shows these lengths in order from the greatest to least is:

{0.6, 0.5222..., 0.13083, 0.09}.

Which is equivalent to:

{3/5, sqrt(3/11), 3.14/24, 9/100}.

Answer: 6 hours

Explanation:

We have that "Ruth studied 2 hours less than twice as many hours as Jackie". I will call the hours that Ruth studied "R" and the hours that Jackie studied "J". The first equation is as follows:

The hours that Ruth studied as 2 less than twice as many as Jackie. This will be referred to as equation 1.

Now, we are told that "Together, their study time was 10 hours" so we have the following equation:

This will be our equation 2.

The next step is to substitute equation 1 into equation 2:

And we solve for J.

Combining like terms:

We add +2 on both sides of the equation to cancel the -2 on the left side:

And we divide both sides by 3:

Jackie studied for 4 hours.

Since we are asked for Ruth, we substitute J=4 into the equation 1:

Ruth studied for 6 hours.

Solution:

According to the problem, a regular work week consists of 5 work days with 8 hours a day. This is equivalent to say:

5 x 8 hours every regular work week.

That is:

40 hours every regular work week

then, the money earned per hour is:

then we can conclude that the correct answer is:

$7.5

The function given in the graph stretches from negative to positive infinity.

Hence the domain of the function is given by:

if the number of shoppers increases by 20% daily and 671 shoppers had visited over 4 days then let the num ber of shoppers on the first day be x

The numebr of shopperes the next day will be

= 1.2x

teh number of shoppers the day after

= 1.2x(100 + 20)%

Given that the total number of people that have shopped after 4 days is 671 then

x + 1.2x + 1.44x + 1.728x = 671

5.368x = 671

x = 671/5.368

= 125

if the number of shoppers increases by 20% daily and 671 shoppers had visited over 4 days then let the num ber of shoppers on the first day be x

The numebr of shopperes the next day will be

= x(100 + 20)%

= 1.2x

teh number of shoppers the day after

= 1.2x(100 + 20)%

= 1.44x

the next day, the number

= 1.44x (100 + 20)%

= 1.728x

Given that the total number of people that have shopped after 4 days is 671 then

x + 1.2x + 1.44x + 1.728x = 671

5.368x = 671

x = 671/5.368

= 125

45/152 is fraction of the students are freshmen.

Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction is a portion of a whole and is used to represent how many pieces of a particular size there are while speaking in ordinary English, for example, one-half, eight-fifths, and three-quarters. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. There is a proportion there in numerator or denominator of a complicated fraction. There are three main categories of fractions in mathematics. Proper fractions, incorrect fractions, and mixed fractions are these three types. The expressions with a numerator and a denominator are called fractions.

ANSWER

2, 4 and 8

EXPLANATION

We have that in a triangle ABC, AB = 3 cm and BC = 5 cm.

To find the possible length of AC, we can apply the triangle inequality theorem.

It states that in any triangle, the sum of the lengths of any two sides must be greater than or equal to the length of the remaining side.

This means that:

So, we have that:

We have to disregard the third line, since the length of a triangle side can only be positive.

So, using the first 2 lines, we see that:

This means that from the options, the measure of AC can either be 2, 4 or 8.

Answer:  expect to lose 679.07 dollars

==========================================================

Explanation:

Assuming each free throw is independent of any other, the probability of making the next free throw is 359/449

The probability of making 3 in a row is (359/449)^3 = 0.511145 approximately which represents the probability of earning the $39

That must mean 1-0.511145 = 0.488855 is the approximate probability of losing $43

Let's make a table of outcomes and their associated probabilities.

X = amount of money the player earns (the person shooting the free throws)

[tex]\begin{array}{|c|c|} \cline{1-2}\text{X} & \text{P(X)}\\\cline{1-2}39 & 0.511145\\\cline{1-2}-43 & 0.488855\\\cline{1-2}\end{array}[/tex]

Then from here we'll multiply each X and P(X) value for each separate row.

Example: 39*0.511145 = 19.934655

Let's form a third column of these products

[tex]\begin{array}{|c|c|c|} \cline{1-3}\text{X} & \text{P(X)} & \text{X}*\text{P(X)}\\\cline{1-3}39 & 0.511145 & 19.934655\\\cline{1-3}-43 & 0.488855 & -21.020765\\\cline{1-3}\end{array}[/tex]

Add up everything in the X*P(X) column and you should get roughly -1.08611 which rounds to -1.09

The player expects, on average, to lose about $1.09 each time they play this game. Playing 623 times means they should expect to lose 623*1.09 = 679.07 dollars

Of course, given the nature of this random process, it's not a guarantee they will lose this amount. This is just the average of many attempts.

Answer:

Yes, the set of ordered pairs is a function.

Explanation:

To test whether a given set of ordered pairs represents a function, we have to make sure that it satisfies the definition.

By definition, a function cannot have two outputs for one input. For example, the set of ordered pairs (3, 10 ) and (4, 5) represents a function whereas (3, 10) and (3, 13) does not.

With this in mind, looking at the given set we see that every input gives a unique output; therefore, the set represents a function.

Explanation:

f⁻¹(8) is equal to the value of x that makes f(x) = 8. So, taking into account the graph, we get:

Therefore, f⁻¹(8) = 2. So the answer is 2

Using the matrix equation, the value of x and y are 5 and 2 respectively.

Consider the 2 by 2 matrix equations,

1/2 [ 4  8     ( x + 3 )   - 4 ] - 3[ 1  y+1    -1  - 2 ] = [ - 1  -5   7  4 ]

[ 2   4       (x+3)/2    -2] + [ - 3   -3y -3   +3  + 6] = [ - 1 - 5    7  4]

[ -1  -3y + 1    (x + 9)/2   + 4]  = [ - 1 - 5   7  4]

Therefore,

- 3y + 1 = - 5

Subtracting 1 from each side of the equation,

- 3y + 1 - 1 = - 5 - 1

- 3y = - 6

Dividing each side of the equation by - 3,

y = 2

And;

( x + 9 )/2 = 7

Multiplying each side by 2,

x + 9 = 14

Subtracting 9 from each side of the equation,

x + 9 - 9 = 14 - 9

x = 5

Therefore, the value of x and y is 5 and 2 respectively.

In order to find the greatest common factor (GCF) of the terms, first let's factor the numeric values in their prime factors:

The common factor between these three numbers is the product of the common prime factors, that is, 2 * 2 = 4.

Now, to find the common factor of the variables, we choose for each variable the one with the smaller exponent:

Therefore the common factor is -4(m^5)n.

(we can put the negative signal as well, since all terms are negative).

So, our answer is 9!

The sum of the internal angles in a triangle equals 180°

R + B = T = 180

Substitution

19 + 56 + T = 180

T = 180 - 19 - 56

T = 105°

Result:

T = 105°

We are given that each face of a pyramid is an isosceles triangle and that its vertex angle is 70 degrees. This problem can be exemplified in the following diagram:

Since the triangle is isosceles, its base angles are the same, and the sum of the interior angles must be equal to 180 degrees. Therefore, we have the following relationship:

Adding like terms, we get:

Now we solve for "x", first by subtracting 70 on both sides:

Now we divide both sides by 2

Therefore, the base angles of the pyramid are 55 degrees.

Answers:

Part A.

C. AD = AE

Part B.

BC = 26

Explanation:

Part A.

If DE is a midsegment of triangle ABC, D is a point that divides AB into two equal segments, so option A. 1/2 AB = AD is true.

Additionally, if DE is a midsegment of triangle ABC, its length is equal to half the length of the side that the segment doesn't cross. So:

Therefore, option B is also true.

Triangle ABC is scalene, it means that all their sides have different length, it means that AD is not equal to AE and option C is not true.

Finally, segments AE and EC form AB, so:

AC = AE + EC

AC - AE = AE + EC - AE

AC - AE = EC

So, option D is also true.

Therefore, the answer for part A is C. AD = AE

Part B.

We know that 2DE = BC, so replacing the expression for each segment, we get:

Solving for x:

Now, with the value of x, we get that BC is equal to:

BC = 5x - 4

BC = 5(6) - 4

BC = 30 - 4

BC = 26

So, the answer for part B is 26.

Replace f (x) = - 2x- 5 ​, then:

-21 < f (x) < 0

-21 < -2x-5 < 0

Solve -21 < -2x-5 and -2x-5 < 0

Therefore:

-21 < -2x-5

Add both sides 5

-21+5 < -2x-5 +5

-16 < -2x

(-1)-16 < (-1)(-2x)

16>2x

x<16/2

x<8

and

-2x-5 < 0

Add both sides 5

-2x-5 +5 < 0+5

-2x<5

(-1)-2x < (-1)5

2x > -5

x > -5/2

Hence, the resulting interval is:

-5/2 < x < 8

qANSWER

Company B will pay more

Company A =

EXPLANATION

Both companies start by paying $42,000 per year.

Company A offers an increase of $1000 per year.

This means that after n years, he would have earned:

Earnings = 42000 + 1000n

where n = number of years after the first year

So, after 6 years, he would have worked 5 years after the first, so his earnings would be:

Earnings = 42000 + 1000(5) = 42000 + 5000

Earnings = $47000

Company B offers 7% more than the previous year. That means that his earnings are compounded.

His earnings can then be represented as:

where P = initial salary = $42000

r = interest rate = 7%

t = number of years spent = 6 years

Therefore, his earnings after the 6th year will be:

He would have earned $63042.

Therefore, Company B will pay more.

Step-by-step explanation:

This problem invloves the topic of curved lines in a graph, curved lines or more speccifically curve line which looks like letter C (parabola) all follows a certain standard form of equation, which is;

For example you can see that the equation for the black curve line in our picture is y=x² and notice that this equation can also be written as y = (1)x² + 0. Which simillar to the standard form given above where a is just 1 (a=1) and b is just 0 (b=0).

Since our black curve line follows the same standard form of equation as stated above, we can conclude that the RED curve line follows the same form of equation.

To summarize the steps that we must do in order to find the equation of the RED line we will list them as,

1. Sample two(2) points in the graph to be used as reference points.

2. Use the sampled points in our standar eqation in order to find the variables "a" and "b".

3. When we have the variables "a" and "b", we can just directly substitute it into our standard equation to find the equation of our RED line.

Let's start.

1. Sample 2 points to be used as refernce points. (Note that we will find the easiest points

to determine)

Let us use the points (-3, -1) and (-2, 1) as shown in the picture.

2. Use the points (-3, -1) and (-2, 1) in our standard equation.

for our 1st point we have the equation 9a+b = -1, let us now proceed to our next point.

and for our 2nd point we have the equation 4a+b = 1, and by the process of subtitution and elimination we can now find "a" and "b", because we have two equations with two unknowns.

transforming eqatuin number 1 to

then substitue b = -1 -9a to the 2nd equation we have.

since a = -2/5, we can find b using,

therefore our a and b are;

3. We can now proceed in substituting it in our standard equation;

you can also simplify the final equation by multiplying all sides by 5,

therefore our final answer can be,

Convert 7 liters into gallons

We have the measurement conversion 1 liter= 1.0567 quarts

and the gallons = 4 quarts

So, 7 liters = 7 * 1.0567 quarts = 7.3969 quarts

We will convert from the quarts to gallons as follows:

1 gallons = 4 quarts

x gallons = 7.3969 quarts

so, the value of x will be:

Round to two decimals

so, the answer will be 1.85 gallons

Explanation:

The equation is given below as

Step 1:

Collect similar terms, we will have

Hence,
