A club with 76 members is planning a camping trip They need to rent cabins and tents for sleeping.
lozanna [386]
The answer is B.4 because you need to divide 76 by 8 which will give you 9.5. Now, you can't have half of a person; so just cut it off. So divide that again by 2 and your answer is B.4 tents.

1/2 = 1/a + b/c make b the subject​
SCORPION-xisa [38]

Answer:

b = \frac{ac-2c}{2a}

Step-by-step explanation:

Given

\frac{1}{2} = \frac{1}{a} + \frac{b}{c}

Multiply through by 2ac to clear the fractions

ac = 2c + 2ab ( subtract 2c from both sides )

ac- 2c = 2ab ( divide both sides by 2a )

\frac{ac-2c}{2a} = b

suppose you deposit $2,475 in a savings account that earns 6.25% simple interest per year. How much simple interest would be ear
Nikolay [14]

$116.02 interest will be earned in 9 months

Step-by-step explanation:

The formula for simple interest is given by:

I = Prt

Here

P is the initial amount

r is the interest

t is the time measured in years

Given

P = $2475

r = 6.25% = \frac{6.25}{100} = 0.0625

t = 9 months

Converting time into year by dividing by 12

t = \frac{9}{12}\ years = 0.75\ year

Putting the values in the formula

I = 2475 * 0.0625 * 0.75\\I = 116.0156

Rounding off to nearest hundredth

I = $116.02

Hence,

$116.02 interest will be earned in 9 months
