Answer:

Step-by-step explanation:

1. The cube root is found by dividing the exponents by 3.

[tex]\sqrt[3]{27a^{12}}=(3^3\cdot a^{12})^{\frac{1}{3}}=3^{\frac{3}{3}}\cdot a^{\frac{12}{3}}=\boxed{3a^4}\qquad\text{matches d}[/tex]

The factoring of the difference of cubes is ...

a³ -b³ = (a -b)(a² +ab +b²)

Here, we have a=r^9 and b=s^10, so the factorization is ...

[tex]r^{27}-s^{30}= (r^9-s^{10})(r^{9\cdot2}+r^9s^{10}+s^{10\cdot2})\\\\=\boxed{(r^9-s^{10})(r^{18}+r^9s^{10}+s^{20})} \qquad\text{matches d}[/tex]

4(x + 1) and 4(x - (-1))

Step-by-step explanation:

4(-1 + 1) = 4(0) = 0

(4 (-1) + 5) = -4 +5 = -1

4(-1 - 1) = 4(-2) = -8

(5 - 4(-1)) = 5 + 4 = 9

4(-1 - (-1)) = 4(0) = 0

4 (-1 + (-1)) = 4(-2) = 8

There are 18 girls in Mr. Brimley's math class. If 40% of the students are girls, what is the best estimation for the number of boys in the class?

Answers

Answer:

Step-by-step explanation:

This is an easy one.

So, we know that 40% of the class is girls. We would need to use the other 60% as 60% of the class is boys and we would need to divide.

18/0.6=30

Therefore your answer is 30.

Hope this helps.

Answer:

Step-by-step explanation:

It is 40 percent ( given)

What is a and b pls answer ASAP I need it !!! Plsss

Answers

Answer:

The value of a = 5.

the value of b = 6.

Step-by-step explanation:

Given the points on the line

(6, 10)(a, 8)(4, b)(2, 2)

Given that all of the points are on the same line and the line represents a linear function.

Thus, the slope between any two points must be the same.

First, determine the slope between (6, 10) and (2, 2)

(x₁, y₁) = (6, 10)

(x₂, y₂) = (2, 2)

Using the formula

Slope = m = [y₂ - y₁] / [x₂ - x₁]

= [2 - 10] / [2 - 6]

= -8 / -4

= 2

Thus, the slope of the line = m = 2

Determine the value 'a'

(x₁, y₁) = (6, 10)

(x₂, y₂) = (a, 8)

Using the slope formula to determine the value of 'a'

Slope = [y₂ - y₁] / [x₂ - x₁]

As the slope between two points is 2.

now substitute slope = 2, (x₁, y₁) = (6, 10) and (x₂, y₂) = (a, 8) in the slope formula

Slope = [y₂ - y₁] / [x₂ - x₁]

2 = [8 - 10] / [a - 6]

2(a - 6) = 8 - 10

2a - 12 = -2

2a = -2 + 12

2a = 10

divide both sides by 2

a = 5

Therefore, the value of a = 5.

Determine the value 'b'

(x₁, y₁) = (2, 2)

(x₂, y₂) = (4, b)

Using the slope formula to determine the value of 'b'

Slope = [y₂ - y₁] / [x₂ - x₁]

As the slope between two points is 2.

now substitute slope = 2, (x₁, y₁) = (2, 2) and (x₂, y₂) = (4, b) in the slope formula

Slope = [y₂ - y₁] / [x₂ - x₁]

2 = [b - 2] / [4 - 2]

2(4 - 2) = b - 2

8 - 4 =b - 2

4 = b - 2

b = 6

Therefore, the value of b = 6

Answers

Answer:

The value of angle 2 is 114 degrees

Step-by-step explanation:

We start with 180 degrees, since it is a Line.

To fine the other degree, subtract 66 from 180, which is 114

Angle 2 is 114 because of the theory of interior alternate angles are congruent. Angle 1 is 66 degrees because of the same reason.

I'm assuming that there's 100% of the lawn so if Ms Rios mowed 27% of the lawn when it was at 100% it would be at 73%

Now if her son mowed 14% and it was still at 100% it would be at 86%

Solve the inequality for x.
- 4x + 16 > -64
A)
X> 12
B)
X > 20
x < 12
D
x < 20

Answers

Answer:

D: x < 20

Step-by-step explanation:

-4x + 16 > -64

subtract 16 from both sides because you must isolate x.

-4x + 16 - 16 > -64 - 16

-4x > -80

Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...

-4x/ -4 < -80/ -4

x < 20

(negative divided by a negative will result in a POSITIVE.)

Hope this helped... I truly apologize if this is wrong..

Find the value of x 8.5,9,7.5,6,7,x ;the mean is 8

Answers

Answer:

x= 10

Step-by-step explanation:

Mean is the sum of all values divided their number

(8.5+ 9 + 7.5 + 6 + 7 +x) / 6 = 8

(8.5+ 9 + 7.5 + 6 + 7 +x) = 8*6 = 48

(8.5+ 9 + 7.5 + 6 + 7 +x) =48

(38 +x) = 48

x= 48-38 = 10

Andrew 720 seconds take shower and 420 seconds eating breakfast how many minutes does it take Andrew take a shower and eat breakfast

Answers

Answer:

Total time = 19 minutes.

Step-by-step explanation:

Given the following data;

Time to shower = 720 seconds

Time to eat breakfast = 420 seconds

To find the total time in minutes;

Total time = 720 + 420

Total time = 1140 seconds

We know that 60 seconds equals a minute.

Total time = 1140/60

Total time = 19 minutes.

Therefore, it will take Andrew 19 minutes to take a shower and eat breakfast.

How do you solve 13 + 3 - 8x + 6 = 1 - 5x I dont get it

Answers

Answer:

x = 7

Step-by-step explanation:

How to solve your question

Your question is 13 + 3 − 8x + 6 = 1 − 5x

13 +3 - 8x + 6 = 1 - 5x

13 + 3 − 8x + 6 = 1 − 5x

Solve

Add the numbers

13 + 3 − 8x + 6 = 1 − 5x

22 − 8x = 1 − 5x

Rearrange terms

22 − 8x = 1 − 5x

−8x + 22 = 1 − 5x

Subtract 22 from both sides of the equation

−8x + 22 −22 = −5x + 1 − 22

Simplify

Subtract the numbers

−8x = -5x + 1 -22

-8x = -5x -21

Add 5x to both sides of the equation

-8x + 5x = -5x -21 + 5x

Simplify

Combine like terms

-3x = -21

Divide both sides of the equation by the same term

(-3x)/3 = (-21)/3

Simplify

Cancel terms that are in both the numerator and denominator

x = (-21)/(-3)

Divide the numbers
