Answer:

320

Step-by-step explanation:

2 out of 5 is the ratio 2/5.

We want the denominator to become 800.

$\dfrac{800}{5} = 160$

$160 \times 2 = 320$

$\dfrac{2}{5} = \dfrac{2 \times 160}{5 \times 160} = \dfrac{320}{800}$

Since 2/5 = 320/800, he will need to prepare 320 cups of soup.

Step-by-step explanation:

The formula for the volume of a square pyramid is $a^{2} \frac{h}{3}$ . a is your base edge and the h is your height. In this case it would be $5^{2} \frac{7}{3}$ . when you wokr it out it would be 58.333, or 58 which is c.

also you would do 5 x 5 then you would multiply it by 7/3.

Sonja [21]

Answer:

$\large\boxed{C)\ 5cm}$

Step-by-step explanation:

$P=2(l+w)\\\\\text{Put}\ l=2cm\ \text{and}\ w=\dfrac{1}{2}cm\ \text{to the formula of the perimeter:}\\\\P=2\left(2+\dfrac{1}{2}\right)=(2)(2)+(2)\left(\dfrac{1}{2}\right)=4+1=5\ cm$

PLEASE HELP!!

ad-work [718]

Step-by-step explanation:

5^-2= 1/25 (as when taken up 25 it becomes 5^-2).
2^5= 32 (when we multiply 2 for 5 times, we get 32).(2×2×2×2×2)
2^-4=1/16 (as when we take up 16 we get 2^-4)
5^3=125 (when we multiply 5 for 3 times we get 125)(5×5×5)

Hope it helps...
