A jar contains 50 marbles, of whice 10 are blue 15 are red and the rest are green what is the ratio of green marbles to all marb

Viefleur [7K]

Answer:

1:2

Step-by-step explanation:

First, find how many are green

Add up the number of blue and red ones:

10 + 15 = 25

Subtract this from 50

50 - 25 = 25

So, 25 are green.

Since there are 50 marbles in total, the ratio will be 25:50

This can be simplified, since both numbers are divisible by 25.

So, the ratio is 1:2

future value of 10% savings from earnings of 36000 earns 6.25% annual interest compounded quarterly for 15 years

hoa [83]

without further ado

10% of 36000 is simply 3600, we chopped a "0" off of it hmmm, ok so

$~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$3600\\ r=rate\to 6.25\%\to \frac{6.25}{100}\dotfill &0.0625\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{quarterly, thus four} \end{array}\dotfill &4\\ t=years\dotfill &15 \end{cases} \\\\\\ A=3600\left(1+\frac{0.0625}{4}\right)^{4\cdot 15}\implies A=3600(1.015625)^{60}\implies A\approx 9126.53$
