Answer:
It is not true it is false.
Step-by-step explanation:
since 2^2+3^2=4^2
4+9=16
13≠16
Answer:
4.62%
Step-by-Step Explanation:
Ask yourself: "3 is what percent of 65?" and solve.
Percentage solution with steps:
Step 1: We make the assumption that 65 is 100% since it is our output value.
Step 2: We next represent the value we seek with <em>x</em>.
Step 3: From step 1, it follows that 100%=65.
Step 4: In the same vein, x%=3.
Step 5: This gives us a pair of simple equations:
100%=65(1)
x%=3(2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100% / x% =65 / 3
Step 7: Taking the inverse (or reciprocal) of both sides yields
x% / 100% =3 / 65
---> x = 4.62%
Therefore, 3 is 4.62% of 65.
Volume of the pool = πr²h
Volume of the pool:
π(13)²(4) = 2123.72 ft³
Amount of water :
1 ft³ = 7.48 gallon
2123.72 ft³ = 2123.72 x 7.48
2123.72 ft³ = 15885.4 gallons
Cost to fill the pool:
1000 gallon = $2
15885.4 gallons = $32
Answer: $32
