Fudgin [204]

Answer:

205 litres

Step-by-step explanation:

The expression that gives the volume of water in Eduardo's pool (in liters) is:

100 + 20m

where m is time, in minutes

After 5\frac{1}{4} minutes (\frac{21}{4} minutes), the volume is will be:

100 + (20 * \frac{21}{4} )\\\\\\100 + (5 * 21)\\\\\\100 + 105

= 205 litres

The volume of water in the poll will be 205 litres.

Help me Please! Find the volume and surface area for all.
HACTEHA [7]

Answer:

V =41.41³

A = 94.41²

----

V =225.16³

SA =283.25²

----

V = 64³

SA =113.32²

----

V =433.33³

SA = 378.57²

Step-by-step explanation:

Picture 2 = a = 1/2 base = 3.5 x 3.5 = 12.25  b= 5 x 5 = 25

c²= a² + b² = 3.5² + 5²

c ²= √12.25 + √25

c ²= √ 37.5 = 6.12372435696

c ² = 6.1237   missing side

Picture 1 + 2  formula SA = bh + (s1 + s2 + s3)H

V =  V= 1/2 b x h  h x SA

Picture 3 + 4  formula SA= a²+ 2a   a² / 4 + h²    V= a²  h/3
