Answer:

$247.50

Step-by-step explanation:

You didn't specify, so I am going to assume that it is annual, or yearly, interest.

You want to calculate the interest on $450 at 55% interest per year after 1 year.

The formula we'll use for this is the simple interest formula, or:

I= P × r × t

Where...

P equals the principal amount, which is $450.00.

r equals the interest rate, which would be 55% per year, or as a decimal, 55/100=0.55.

t equals time involved, which is 1 year

To find the simple interest, we multiply 450 × 0.55 × 1 to get that the interest is $247.50

If I have a circle that is 12 in in diameter and it's cold and a half and then folded in half again what is the area of the resu
nika2105 [10]

Answer:

<h2>A= πr^2/4</h2>

Step-by-step explanation:

Step one:

given data

diameter of circle= 12 in

the radius is r=d/2=6in

the area of the circle is

A=πr^2

A=3.142*6^2

A=3.142*36

A=113.1in^2

If the circle is folded in half, the area will be A/2= 113.1/2= 56.55in^2

In the corresponding shape is folded again the area is A/4= 28.3in^2

<u>The expression for the last shape is </u>

<u>A= πr^2/4</u>

Morgarella [4.7K]
Total people=180
discount received people=25%+10%=35%
People who did not receive discount=100-35%=65%
65%of 180=65×180/100=117
So 117 people did not receive discount

If x/2+ 7 = 4<br> , what is the value of 5x - 7?
horrorfan [7]

Answer:

-37

Step-by-step explanation:

for the first equation to equal 4 the x must equal -6.

because something plus 7 had to equal 4. and we know that -3 + 7 equals 4. Now, -6 ÷ 2 equals -3 and that gives us the right answer.

So now plug -6 into the new problem so now it is

5 × (-6) - 7 so according the PEMDAS, we do 5 × -6 first which is -30. and -30 - 7 equals -37!!

hope this helps :)
