Alina [70]

Answer:

Amount of water left in tank = 440 cm³

Step-by-step explanation:

Given:

Sides of tank respectively = 35 cm , 28 cm , 16 cm

Water level in tank = 2/5

Side of a cubic tank = 18 cm

Find:

Amount of water left in tank

Computation:

Volume level in rectangular tank = [2/5][35 x 28 x 16]

Volume level in rectangular tank = [2/5][15,680]

Volume level in rectangular tank = [31,360/5]

Volume level in rectangular tank = 6,272 cm³

Volume of cube = side³

Volume of cube = 18³

Volume of cube = 5,832 cm³

Amount of water left in tank = Volume level in rectangular tank - Volume of cube

Amount of water left in tank = 6,272 - 5,832

Amount of water left in tank = 440 cm³

Polygons ABCD and EFGH are similar. Find the length of EH?

3241004551 [841]

Most likely, polygon ABCD has sides of known lengths.
It is also likely that one of the sides of polygon EFGH (not EH) is also known. For instance, its side EF.

If the above is true, we can find the scaling factor as a ratio between lengths of corresponding sides:
r=EFAB

Since this ratio is constant for any two corresponding lengths,
r=EHAD

From the last two equations we can derive:
EH=AD⋅EFAB

dangina [55]

Answer:

Step-by-step explanation:

i'm pretty sure that you will have to add it.

so, when we add two fractions such as 3/4 + 3/4, we make sure that the denominators (the bottom numbers) are the same and then we simply add the numerators (the top numbers).

in this problem, the denominators are the same so we will simply add 3+3 which equals to 6/4. the denominator will remain the same.

answer:

3/4 + 3/4 = 6/4

i hope this is helpful.
