3/7 of 8th graders play sports. is 3/5 of the 8th graders that play sports are boys, what fraction of the 8th graders are boys
Svetach [21]

Answer:

\dfrac{9}{35} is the fraction of 8th graders who are boys.

Step-by-step explanation:

Let total number of 8th graders = x

Given that, \frac{3}{7} of 8th graders play sports

\Rightarrow 8th graders who play sports = \frac{3}{7} \times x

Also, Given that, \frac{3}{5} of 8th graders that play sports are boys

Number of 8th graders that play sports, and are boys = \frac{3}{5} \times \text{Number of 8th graders who play sports}

\Rightarrow \dfrac{3}{5} \times \dfrac{3}{7} \times x\\\Rightarrow \dfrac{9}{35} \times x

Hence, the answer is:

\dfrac{9}{35} is the fraction of 8th graders who are boys.

ASHA 777 [7]

Answer:

n=\frac{8}{3}  or  n = 2\frac{2}{3}

Step-by-step explanation:

Multiply both sides of the equation by \frac{10}{3}

(\frac{10}{3}) (\frac{3}{10})*n= (\frac{10}{3})(\frac{4}{5})

Simplify both sides of the equation.

n=\frac{8}{3} or n = 2\frac{2}{3}

find the final balance in an account with $660 invested at 3.5% annual simple interest for five years.
Kisachek [45]
The equation for simple interest is:
A=P(1+rt)
Where:
A=amount
P=principal amount
r=rate as a decimal
t=time
So:
660(1+(0.035×5))=$775.50
