Answer:

6/5

Step-by-step explanation:

Calculate the volume by multiplying the measured length and width of the space together, then multiply the result by the height of the room. From the example, 10 * 25 feet = 250 square feet, and 5 * 10 feet = 50 square feet.

Answer:

91 adult tickets

Step-by-step explanation:

Algebra is really useful here:

Let a = number of adult tickets sold and c = number of child tickets sold.

Thus, we can say that

a + c = 153 (number of tickets)

6.40c + 9.60a = 1270.4. (cost of all of the tickets)

Solving,

c = 153 - a

6.40(153 - a) + 9.60a = 1270.4

979.2 - 6.40a + 9.60a = 1270.4

3.20a = 291.2

a = 91

Answer:

x is 5 and y is 6

Step-by-step explanation

we find 2/3 factors that equal 10. 2 and 3. the only other number that can be added that equals 10 is 5. i apply the same logic to y

Answer:

Y -- 6

X -- 5

Step-by-step explanation:

we first find y by finding the side that is the longest that is parallel to y (16) we also find that two sets of fives are also parallel to y and 16 as seen in the first screenshot. Then to find the missing value we will subtract the 5 two times from 16 to find y. 16 - 5  = 11 - 5 = 6.

we do the same thing to find x, (10 - 2 = 8) (8 - 3 = 5) X = 5

3 ( 3x + 6 + x ) = 1

Step 1, apply distributive method.

9x + 18 + 3x = 1

Step 2, simplify the following

12x + 18 = 1

Step 3, Change side

12x = -17

Final answer

x = -17/12

The error/mistake was in step 2 where [ 9x +3x = 12x ]

Recheck the answer

3 ( 3x + 6 + x ) = 1

3 ( 3(-17/12) + 6 + -17/12 ) = 1

1 = 1

Hence proved our solution is correct.

Answer:

Question 1

The error is in step 2.  They have subtracted [tex]3x[/tex] from the left side of the equation, yet only subtracted 3 from the right side.

Questions 2 & 3

Solve:

[tex]3(3x + 6 + x) = 1[/tex]

Apply the distributive law [tex]a(b + c) = ab + ac[/tex] :

[tex]\implies 9x + 18 + 3x = 1[/tex]

Collect and combine like terms:

[tex]\implies 9x + 3x+ 18 = 1[/tex]

[tex]\implies 12x + 18 = 1[/tex]

Subtract 18 from both sides:

[tex]\implies 12x + 18 - 18 = 1 - 18[/tex]

[tex]\implies 12x = -17[/tex]

Divide both sides by 12:

[tex]\implies \dfrac{12x}{12}=-\dfrac{17}{12}[/tex]

[tex]\implies x=-\dfrac{17}{12}[/tex]

Answer:

Answer:

1/6 < 1/3 < 1/2 < 2/3

Step-by-step explanation:

We can turn the following to decimal;

1/6 = 0.16666666666        

2/3 = 0.66666666666

1/2 = 0.5

1/3 = 0.33333333333

0.16666666666   < 0.33333333333 < 0.5 < 0.66666666666

Thus, from least to greatest is 1/6 < 1/3 < 1/2 < 2/3

Answer:

6 visits

Step-by-step explanation:

Plan A: 139+8x

Plan B: 43+24x

Set the equations equal to each other.

[tex]139 + 8x = 43 + 24x[/tex]

Subtract 43 from both sides.

[tex]96 + 8x = 24x[/tex]

Subtract 8x from both sides.

[tex]96 = 16x[/tex]

Divide both sides by 16.

[tex]x = 6[/tex]

Answer:

The answer is (-6 + √41), (-6 – √41)

Step-by-step explanation:

We are given an equation

Subtract 5 from both side we get,

x² + 12x – 5 = 5 – 5

x² + 12x – 5 = 0

we get the equation in the form of

Here, a = 1, b = 12, c = (-5)

Now, Add and subtract (b/2a)² we get,

x² + 12x + (12/2)² – (12/2)² – 5 = 0

x² + 12x + (6)² – (6)² – 5 = 0

(x + 6)² – 36 – 5 = 0

(x + 6)² – 41 = 0

Now, add 41 both side we get,

(x + 6)² – 41 + 41 = 0 + 41

(x + 6)² = 41

√(x + 6)² = √41

x + 6 = ±√41

x = -6 + √41, -6 – √41

Thus, The roots of the equation is

(-6 + √41) and (-6 – √41).

Using a discrete distribution, it is found that Darya's expectation for this listing is of $13,700.

The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.

In this problem, considering the situation described in the text, the distribution is given by:

Hence, her expectation is given by:

E(X) = 0.8 x 17,700 - 0.2 x 2,300 = $13,700.

Answer:

1. 52yard²

2. $54

3. 30.5

Step-by-step explanation:

1. area of square shape = lenght x breadth

= 4 * 4

= 16

area of rectangle shape = lenght x breadth

= 9 * 4 = 36

tatal area = 16 + 36

= 52yard²

2. let the cost = c

thus 9% * c = 4.86

c = 4.86 * 90%

c = $54

3.area of length traingle=1\2 *base * height

= 1\2 * 3 * 7

= 10.5

area of right quadrilateral= legnth*bredth

= 4 * 3

= 12

area of right traingle = 1\2 * base * height

= 1\2 * 4 * 4

= 8

total area of shape = 10.5+12+8

Answer:52 54 30.5

Step-by-step explanation:

The total number of ways this can be done is 144 ways

Generally, the total outcomes that are there when n objects are spinned is expressed as n!

n! = n(n-1)(n-2)!

If he spins a spinner with four equal-sized sections labeled Red, Green, Blue, Orange and three equal-sized sections labeled Walk, Run, Stop, the total outcome is expressed as:

Total outcome = 4! * 3!
Total outcome = 24*6
Total outcome = 144 ways

Hence the total number of ways this can be done is 144 ways
