cube means 3D  square.. right?

so for volume  we want the height x width x length.. make sense?

since each edge is 9'  

the volume is [tex]9^{3}[/tex] = 729  [tex]ft^{3}[/tex]

Answer: 729

Step-by-step explanation:

This is very simple all you do is cube 9

Answer:

Let x be the number of pencils Steve bought.

Let y be the number of erasers Steve bought.

x=y+5

0.1x + 0.25y = 1.55

Solving the system, our answer is: (8, 3)

So, she bought 3 erasers.

Answer:

17 problems.

Step-by-step explanation:

19 + 9 = 28

(Amanda is in the afternoon class, so she gets 9 more homework assignments than the morning class, which gets 19.)

28 - 11 = 17

(Amanda has already completed 11 homework problems.)

Answer:

x= 8

Step-by-step explanation:

x^2 = 6x+16

TAKE RHS OVER TO LHS TO EQUATE IT TO 0

x^2 - 6x - 16 = 0

FACTORISE

(x-8)(x+2) =0

Therefore

x-8= 0 or x+2= 0

x= 8 or x= - 2

Sub and see which works

8^2 = 6(8) + 16

64= 64

-2^2 = 6(-2) + 16

-4= 4

So the answer must be

x= 8

Answer:

y=-2x+5

Step-by-step explanation:

Rebecca's car insurance been reduced by 18%

A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction.

Given that, Last year, Rebecca's car insurance cost her £2043. This year it only cost her £1675.26.

Percentage decrease = (Final value - initial value) / initial value × 100

Final value = £1675.26

Initial value = £2043

Percentage decrease = (2043 - 1675.26) / 2043 × 100

= 367.74 / 2043 × 100

= 0.18 × 100

= 18 %

Hence, Rebecca's car insurance been reduced by 18%

The answer for this is -76736

Step-by-step explanation:

Answer:

E = 58

F = 32

G = 90

Step-by-step explanation:

3x + 31 + 5x -13 + 90 = 180

3x + 31 + 5x -13 = 90

8x = 90 - 31 + 13

8x = 72

x = 72 / 8

x = 9

E = 3(9) + 31 = 27+31 = 58

F = 5(9)-13 = 45 - 13 = 32

G = 90

Answer:

The third one

Step-by-step explanation:

The graphs in the reversed shape of a cup are the graphs of quadratic equations whose coefficient of

x^2 is negative.

So, the answer must be either the first or the third.

It can be seen that when x= -4, y becomes 5.

Substituting the value of x, the third equation gives the value 5.

So, the answer is the third one.

Answer:

(- 1, - 2 )

Step-by-step explanation:

Given the 2 equations

y = - 2x - 4 → (1)

y = 4x + 2 → (2)

Substitute y = 4x + 2 into (1)

4x + 2 = - 2x - 4 ( add 2x to both sides )

6x + 2 = - 4 ( subtract 2 from both sides )

6x = - 6 ( divide both sides by 6 )

x = - 1

Substitute x = - 1 into either of the 2 equations and solve for y

Substituting into (2)

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

solution is (- 1, - 2 )
