Hey! Pretty stranger :D

AsnwEr:

Number of girls in class = 15

GivEn:

The ratio of no. of boys to no. of girls in a class is 4:5.
Number of boys in class = 12

To find:

Number of girls in class?

Solution:

☯ Let number of girls be x.

Given that,

The ratio of no. of boys to no. of girls in a class is 4:5.

Therefore,

→ 12/x = 4/5

→ x = 12 × 5/4

→ x = 60/4

→ x = 15

∴ Hence, number of girls in a class is 15.

What is interest earned on 3500 invested at 6% compounded quarterly or 12 years

enyata [817]

$\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to &\$3500\\
r=rate\to 6\%\to \frac{6}{100}\to &0.06\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{quarterly, thus four}
\end{array}\to &4\\
t=years\to &12
\end{cases}
\\\\\\
A=3500\left(1+\frac{0.06}{4}\right)^{4\cdot 12}\implies A=3500(1.015)^{48}$

so, the interest earned then will be A - 3500.

It costs a lumberyard $2.05 per cubic foot of lumber. If they sell the lumber back to their customers for $21.98 per cubic foot

adelina 88 [10]

Answer:

The profit per year will be $23916

Step-by-step explanation:

Cost price of 1 ft³ = $2.05

Selling price of 1 ft³ = $21.98

Profit = Selling price - cost price

profit = $21.98 - $2.05

Profit = $19.93

Profit on 1 ft³ is $19.93

If they sell 100 monthly, per year (12 months), profit will be

19.93*100*12

= $23916
