It's not C. Use the Geometric Mean for right triangles to solve. In our formula, our values will fit in like this: \frac{9}{x}=\frac{x}{9+7}. Simplifying we have \frac{9}{x}=\frac{x}{16}. Cross-multiply to get x^2=144. That means that x = 12. First choice above.

A right square prism has a volume of 75 cubic inches. The prism is enlarged so its height is increased by a factor of 5, but the
kvasek [131]

Answer:

The new volume is 375 cubic inches.

Step-by-step explanation:

Volume of a right square prism:

The volume of a right square prism is given by:

V = a^2h

In which a is the length of the edge and h is the height.

A right square prism has a volume of 75 cubic inches.

This means that:

a^2h = 75

The prism is enlarged so its height is increased by a factor of 5

Edge is the same, height is 5 times. So

a^2(5h) = 5(a^2h) = 5*75 = 375

The new volume is 375 cubic inches.

Mika can eat 21 hot dogs in 6 minutes. She wants to know how many minutes (m) it would take her to eat
kipiarov [429]

Answer:

The answer is 10 minutes.

Step-by-step explanation:

First, convert the known amount of time to a fraction.

6/21 (min over hot dogs).

Set up a proportion.

6/21 = m/35 (m being the number of minutes)

Cross multiply.

210 = 21m

Solve for m. (divide each side by 21)

m = 10

I hope this helps! :)

Tow decimals that are equivalent to 7.7.
PolarNik [594]
7.7 is equivalent to its self, and you can only make more equivalents by adding zero’s on either side, it’s better to add after decimal.

Situation One
navik [9.2K]

Step-by-step explanation:

Total no. of horses and chicken=24

C+H=24

Total no. horses be =24-C

Total no. legs=66

---66=4(24-C)+2C { As horses have 4 legs and chicken has 2 legs}

66=96-4c+2c

66-96=-2c

-30=-2C

Chicken=15

Therefore no. horses=24-C

=24-15

=9horses

There fore no. of chicken legs=15×2 = 30 legs

Therefore no. of horse legs=9×4=36 legs
