During a recent year, charitable contributions in the United States totaled $371 billion. The graph below shows to whom this mon

Angelina_Jolie [31]

Using proportions, it is found that $55.7 billion was donated to educational organizations.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

Of the $371 billion donated in total, 15% went to educational organizations, hence the amount is given by:

A = 0.15 x 371 = $55.7 billion.

Hence $55.7 billion was donated to educational organizations.

A geometric sequence has first term 1/9 and common ratio 3. Which is the first term of the sequence which exceeds 1000?

Svetach [21]

$a_{n}= \frac{1}{9} (3)^{n-1}$
(We know this from a=1/9 and r=3)
Simplifying this, we get:
$\frac{1}{9} (3)^{-1} (3)^n$

Since we're finding the first term that exceeds 1000, let's set it equal to 1000.

$\frac{1}{27}(3)^n=1000$
Multiplying both sides by 27
$3^n=27000$

$log_{3}27000=n$

n≈9.2

We have to round n up, since if n=9, the value would be <1000.
Therefore n=10. Substituting n=10,
$\frac{1}{27}3^{10}$
=2187

Therefore the first term that exceeds 1000 is 2187, and it is the 10th term

An investor invests $2,500 into a mutual fund and earns 5.75% on the principle for each of three years. How much interest has ac

HACTEHA [7]

Answer:

Interest in 3 years = $456.52

Step-by-step explanation:

As we know the the formula of compound interest

Total amount = $A(1+\frac{r}{n})^{nt}$

Here n = number of times amount is compounded

r = rate of interest

t = period

Here A = $2500

r = 0.0575

n = 1 (compounded annually)

t = 3 years

Therefore amount after 3 years

$P=2500(1+\frac{.0575}{1})^{3}$

P =2500(1.0575)³

= 2500×1.18

= $2956.52

We have to calculate the interest then

Interest = $2956.52-$2500 = $456.52

So after 3 years interest gained = $456.52
