Answer:

7.1 (7.06 rounded to the tenth)

Step-by-step explanation:

The formula for Area of a Circle is: π·r²

R = Radius

π = pi, or 3.14

As long as you know the formula, this is easy!

In class, you may have already been told that the radius is <em>half </em>of the diameter.

1. Half of 3 ft is 1.5 ft.

2. Plug 1.5 in for r, in your calculator

3. Do the calculation, and you should come out to get 7.06858347058

4. Round it!

Finding area for a circle is satisfying, isn't it? xD

How much would Vincent have in his account after three years if he started with $100 and earns 5 percent, compounding annually?

Answer:

D. $115.76

Step-by-step explanation:

We will use compound interest formula to solve our given problem.

$A=P(1+\frac{r}{n})^{nT}$ , where,

A= The final amount after T years.

P= Principal amount.

r= Interest rate in decimal form.

n= Period of compounding.

T= Time in years.

Let us convert our given interest rate in decimal form.

$5\text{ percent}=\frac{5}{100}=0.05$

Now let us substitute our given values in compound interest formula.

$A=100*(1+\frac{0.05}{1})^{1*3}$

$A=100*(1+0.05)^{3}$

$A=100*(1.05)^{3}$

$A=100*1.157625$

$A=115.7625\approx 115.76$

Therefore, Vincent will have $115.76 in his account after 3 years and option D is the correct choice.

Bethany gets a sign-on bonus of $50 and earns $100 per day. Jacob gets a sign-on bonus of $65

Elden [556K]

Answer:

Step-by-step explanation:

b=50+100d and j=65+95d they are equal when

50+100d=65+95d subtract 95d from both sides

50+5d=65 subtract 50 from both sides

5d=15 divide both sides by 5

d=3 So after three dsys they will have earned the same amount, using either original equation

50+100(3)=$350 is what they have earned after three days.
