Marta is solving the equation S = 2Πrh + 2Πr2 for h. What is the result?

1 answer:

6 0

S = 2Πrh + 2Πr2
Manipulating the equation for h.
Step 1. subtract 2Πr2 on both sides.

S - 2Πr2 = 2Πrh + 2Πr2 - 2Πr2
S - 2Πr2 = 2Πrh

Step 2 . divide 2Πr on both sides

(S - 2Πr2)/2Πr = 2Πrh/2Πr

h = (S - 2Πr2)/2Πr

Lola and Brandon had a running race. They ran 3/10 of a mile. Lola was in the lead for 4/5 of the distance. For what fraction of

Kruka [31]

Answer:

Lola was in lead for $\frac{6}{25}$ of a mile.

Step-by-step explanation:

We have been given that Lola and Brandon had a running race. They ran 3/10 of a mile. Lola was in the lead for 4/5 of the distance.

To find the fraction of a mile for which Lola was in the lead, we need to find 4/5 of 3/10 as:

$\text{Fraction for which Lola was in lead}=\frac{3}{10}\times\frac{4}{5}$

$\text{Fraction for which Lola was in lead}=\frac{3}{5}\times\frac{2}{5}$

$\text{Fraction for which Lola was in lead}=\frac{3\times2}{5\times5}$

$\text{Fraction for which Lola was in lead}=\frac{6}{25}$

Therefore, Lola was in lead for $\frac{6}{25}$ of a mile.
