Answer:

One motorcycle was going 44 miles and hour and the other motorcycle was going 8 miles an hour faster, so it was going 52 miles per hour.

Step-by-step explanation:

Distance = rate times time

Both motorcycles have a time of 3.  We do not know the rates, but we know that one motorcycle's rate was 8 miles an hour faster.  Let's call motorcycle 1's rate x then motorcycle 2's rate must be (x + 3)

Motorcycle 1

d = 3x

Motorcycle 2

d = 3(x +8)

We know that the total distance together is 288

3x + 3(x+8) = 288  Distribute the 3

3x + 3x + 24 = 288  Combine the 3's

6x + 24 = 288  Subtract 24 from both sides of the equation

6x = 264  Divide both sides by 6

x = 44

One motorcycle was going 44 miles and hour and the other motorcycle was going 8 miles an hour faster, so it was going 52 miles per hour.

The solution to the system of linear equations shows that the cost of 1 kg of turnips is £ 1.1 and the cost of 1kg of mushrooms is  £ 2.9.

A system of equations is the given term of math for two or more equations with the same variables. The solution of these equations represents the point of the intersection.

You can solve a system of equations by substitution or adding methods. In the addition method, you eliminate a variable, on the other hand, in the substitution method you replace a variable for the other.

First, you should convert the text of the problem into equations, thus you can write:

2m + 2.5t = 8.55 (1)

3m + 4t = 13.10  (2)

where: m = mushrooms and t = turnips

For solving this question, you can apply the addition method. Thus, you should follow the steps below:

           6m + 7.5t = 25.65 (1)

          -6m -8t = -26.20  (2)

         -0.5t = -0.55

          0.5t = 0.55

From equation 1, you have 6m+7.5t=25.65 . If t= 11/10, you have

6m + 7.5*11/10 = 25.65 * (100)

600 m + 825 = 2565

600 m = 2565 -825

600 m = 1740

m = 1740/600

m=29/10

m=2.9

From the previous steps, you have the answers for the letter a ( £ 2.9 ) and the letter b ( £ 1.1).

The system of equations involving y = 2x and y = -x + 6 has the solution (2 , 4).

A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.

There are three methods that can be used to solve system of linear equations.

1. Elimination

2. Substitution

3. Graphing

Using substitution method, given two linear equations in x and y,

y = 2x     (equation 1)

y = -x + 6     (equation 2)

Since both equations are in the form of y in terms of x ans dome constant, substitute the first equation to the second equation.

y = -x + 6     (equation 2)

2x = -x + 6

Combining the all terms containing the variable x on one side and the constants on the other side of the equality, and solving for x.

2x + x = 6

3x = 6

x = 2

Substituting the value of x in the first equation,

y = 2x     (equation 1)

y = 2(2)

y = 4

Writing it as an ordered pair, we got (2 , 4) as the solution of the system of equations involving y = 2x and y = -x + 6.

Answer:

answer 1 = 3,5

answer 2 = 1,4

Step-by-step explanation:

The location of the midpoint of the line segment is (37 / 2, 11 / 2).

According to the statement, the position of the two endpoints of a line segment are known and we must determine where the midpoint is, that is, the point such that the line segment is divided into two parts of equal length. The location of the midpoint is found by means of the midpoint formula:

M(x, y) = 0.5 · B(x, y) + C(x, y)        

Where M(x, y) is the midpoint.

If we know that B(x, y) = (15, 7) and C(x, y) = (22, 4), then the location of the midpoint is:

M(x, y) = 0.5 · (15, 7) + 0.5 · (22, 4)

M(x, y) = (15 / 2, 7 / 2) + (11, 2)

M(x, y) = (37 / 2, 11 / 2)

The location of the midpoint of the line segment is (37 / 2, 11 / 2).

D. The solution of the quadratic equation using completing the square method is x = 7 ±√3.

Completing the square method is one of the methods to find the roots of the given quadratic equation.

In completing the square method, we have to convert the given equation into a perfect square.

The given quadratic equation;

x² - 14x + 46 = 0

collect similar terms together;

x² - 14x = -46

take half of coefficient of "x", square it and add it to both sides of the equation.

(x - 7)² = -46 + 49

(x - 7)² = 3

take square root of both sides

x - 7 = ±√3

add "7" to both sides of the equation

x = 7 ±√3

Thus, the solution of the quadratic equation using completing the square method is x = 7 ±√3.

The populace is the concrete produced by a certain procedure. This population is conceptual since the concrete won't exist until the sampling procedure has created it.

It is frequently crucial to ascertain the type of population we are working with when asked to perform a sample of it. Sometimes we want to learn more about a lot of different things, like people, apple trees, cereal boxes, etc. Physical things make up the majority of this population. But occasionally, we work with a population that is determined by how well a certain method works (like flipping a coin). We cannot influence that population, but we are aware of its behavior. The population is the broad category of topics about which we are interested in learning more. Since we are dealing with concrete objects that we can touch and interact with, it is more particularly a tangible population.

Similar to the bag of marbles, we have a 50/50 probability of seeing each result. The population does not yet exist with the coin, which is the problem. To get a result, we must flip a coin. Although it is only a notional population, we nonetheless regard "all of the coin flips" as the conceptual population.

IQR = 13

Step-by-step explanation:

first step is to find the median of the data set.

rearrange the data into ascending order. Then the median is the middle value.

1  ,  6  ,  7  ,  8  ,  12  ,   19  ,  30 ← in ascending order

                   ↑ middle

then median = 8

the interquartile range (IQR) is calculated as

IQR = Q₃ - Q₁ ( Q₃ is the upper quartile and Q₁ the lower quartile )

Q₃ is the middle value of the data to the right of the median

12  ,  19  ,  30

        ↑ middle

then Q₃ = 19

Q₁ is the middle value of the data to the left of the median

1  ,  6  ,  7

     ↑ middle

then Q₃ = 6

IQR = 19 - 6 = 13

Answer:

5.6%

Step-by-step explanation:

1) Find the difference between the initial and final values

In this case, a man's hourly wage increased from $12.50 to $13.20. The difference between the hourly wages is $13.20 - $12.50 = $0.70.

2) Divide the difference by the initial value

$12.50 is the initial hourly wage

($0.70 ÷ $12.50) = 0.56

3) Convert the quotient to a percentage

0.56 x 100 = 56%

The man's hourly wage increased by 56%.

Hope this helps, have a great day!

The percentage is the change with respect to the original amount increase in his hourly wage between year 1 and year 2 will be 5.6%.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

As per the given,

The hourly wage in year 1 = $12.50 an hour

The hourly wage in year 2 = $13.20 an hour

Percentage = change / initial

Percentage = (13.20 - 12.50)/12.50

Percentage = 0.7/12.50

Percentage = 0.056

⇒ 0.056 × 100 = 5.6%

Hence "The percentage is the change with respect to the original amount increase in his hourly wage between year 1 and year 2 will be 5.6%".

Answer: Zero product property

n = 0

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

Explanation:

The zero product property is the idea that if A*B = 0, then either A = 0 or B = 0 or both are zero.

This is because we cannot multiply nonzero values to get a result of zero.

In the equation 5*n*2 = 0, we have 5 and 2 as nonzero, which forces the variable n to be zero. So this is why n = 0 is the only solution here.

-----------------

Extra info:

The zero product property is often used in factoring. For example, x^2+5x+6 = 0 factors to (x+3)(x+2) = 0. Then we set the pieces equal to zero and solve for x

x+3 = 0 leads to x = -3

x+2 = 0 leads to x = -2

The total money Monika spent at the cafe to buy a bacon cheeseburger, large fries and milkshake is $9.9.

Given that, while visiting the zoo, Monika has budgeted $10 for lunch at the café.

To add decimals, write the numbers in a column, and make sure that the decimal points are aligned. To keep the decimal point in your sum, place a decimal point directly below the decimal points in the addends. Align the decimal point in the sum with the decimal point in the addends, and add a zero if necessary.

Cost of a Cheeseburger= $4.75

Cost of a french fries, a large = $1.90

Cost of a milkshake = $3.25.

Now, the total amount spent at the cafe =  Cost of a Cheeseburger + Cost of a french fries, a large + Cost of a milkshake

= (4.75+1.90)+3.25

=6.65 + 3.25

=$9.9
