Answer:

\boxed{Height = 20 cm}

Step-by-step explanation:

Base Area = Length *Width

Base Area = 5*18

<u>Base area = 90 square cm</u>

<u>Volume = 600 cubic cm</u>

Volume = \frac{(BaseArea)(Height)}{3}

<u><em>For Height, it will be:</em></u>

=> Height = \frac{3(Volume)}{BaseArea}

=> H = \frac{3(600)}{90}

=> H = 20 cm

Answer:

20 cm

Step-by-step explanation:

Height is AE.

Find height.

600 = 1/3 × (18 × 5) × h

Base area is the area of square.

Volume is given, solve for h.

600 = 30h

600/30 = h

20 = h

Answer:

The exact number would be 26.66666667 but it would be 26.

Step-by-step explanation:

Usually when dealing with decimals anything 5 and up would be rounded up but since we are dealing with money we don't round up. Since his friends lunch cost $3 every lunch the most he will be able to buy is 26. He will have about $2.5 left over which he cannot buy a lunch with so thats why you dont round up.

hodyreva [135]
Set up a proportion.
Let x = the number of students in 29970 who speak 3 or more languages.

285/19 = 29970/x Cross multiply
285 x = 19 * 29970
285x = 569430
x = 569430/285
x = 5415 students speak 3 languages.

What is length of X and length of Y
luda_lava [24]

Answer:

It is a right angled triangle.

so

tan32 = p/b

or, tan32 = x/5

or, tan32×5 = x

so, x = 3.124

for 5 no. the answer is a. 3.124

For y,

cos32 = b/h

or, cos32 = 5/y

or, y = 5/cos32

so, y = 5.895

for 6 no. 5.895 is closest to 5.994, so the answer is c. 5.994.
