1 answer:

3 0

Option A:

V = 1/3 * b^2 * h

V = 1/3 * 10.5^2 * 6

V = 1/3 * 110.25 * 6

V = 220.5

Option B:

V = 1/3 * b^2 * h

V = 1/3 * 3.6^2 * 8

V = 1/3 * 12.96 * 8

V = 34.56

Option C:

V = 1/3 * b^2 * h

V = 1/3 * 4.2^2 * 12

V = 1/3 * 17.64 * 12

V = 70.56

Option D:

V = 1/3 * b^2 * h

V = 1/3 * 6^2 * 8.4

V = 1/3 * 36 * 8.4

V = 100.8

I guess it's 'None of the Above'

Contact [7]

Answer:

Step-by-step explanation:

Drink mix ratio:

Lemonade : Orange : Cranberry

6 : 3 : C

Fraction of Cranberry juice = $\frac{3}{12}$

Sum of the ratio = 6 + 3 + C = 9 + C

Fraction of Cranberry;

$\frac{C}{9 + C}$ = $\frac{3}{12}$

3(9 + C) = 12C

27 + 3C = 12C

27 = 12C - 3C

9C = 27

C = 3

Answer:

11. x=15 , 12. x=-16, 13 x is greater than or equal to 15 , 14 x=-3 , 15 x=-3, 16 x=15/2 , 17 x is greater than is equal to -4, 18: x is greater than -11

Step-by-step explanation:

11. 4x+15=75

subtract 15

4x=60

divide

x=15

12. 2x = -32 (subtract 13 from each side)

divide

x=-16

13. multiply each side by

-3/2

x is greater than or equal to 15

14. -3x -18 + 5 = -4

isolate x

-3x=9

x=-3

15. -5x-30 +5=-10

isolate x

-5x = 15

x= -3

16. 2x + 16 = 6x - 14

isolate x

4x = 30

x= 15/2

17 isolate x

x is greater than is equal to -4

18. isolate x

x is greater than -11

Sarah needs to have a plumber come to her house and fix a leaky faucet in her bathroom. The plumber charges $50 to come to her h

klio [65]

Answer:

Sarah can have the plumber work on her faucet for six (6) hours maximum

Step-by-step explanation:

As Sarah has only $234.50 in her savings and the plumber charges $50 just to come to her home, so left-over $184.50 of her saving for pay work hours.

Then as the plumber charges $30.75 per hour we have that $\frac{\$ 184.50}{\$ 30.75/h}=6h$ is the maximum amount of hours that Sarah can have the plumber work on her faucet.
