Answer:

35 cubic feet

Step-by-step explanation:

127 137

If you divide the foam into 2 rectangular prisms, you will get a rectangular prism with dimensions of 1 * 2 * 7, and another prism with dimensions of 1 * 3 * 7. You find the separate volumes of each, and get 14 ft^3, and 21 ft^3. You add these together to get 35 ft^3

Lynna [10]

Answer:

465

Step-by-step explanation:

Since we are looking for the the number of combinations to have 2 different flavors in the ice cream, we can use the formula for combination.

_{n}C_{k}=\dfrac{n!}{k!(n-k)!}

Our variables are:

n = 31

k = 2

_{31}C_{2}=\dfrac{31!}{2!(31-2)!}

_{31}C_{2}=\dfrac{31!}{2!29!}

_{31}C_{2}=\dfrac{31!}{2!29!}

_{31}C_{2}=465

The number of possible combinations of having 2 different flavors out of 31 different flavors is 465.

Please show the work
Alex Ar [27]

Step-by-step explanation:

15t + 30 = 20t | -15t

30 = 5t

t = 30/5 = 6

20 + 5t = -6t + 86 | + 6t

20 + 11t = 86 | -20

11t = 66

t = 6

18t + 20 = 24t + 50 | -18t

20 = 6t + 50 | -50

-30 = 6t

t = -30/6 = -5

18t - 2 = 10t + 54 | -10t

8t - 2 = 54 | +2

8t = 56

t = 56/8 = 7

7t - 5 = 15t + 91 | -7t

-5 = 8t + 91 | -91

-96 = 8t

t = -96/8 = -12
