Answer:

$280

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 2%/100 = 0.02 per year,

then, solving our equation

I = 2800 × 0.02 × 5 = 280

I = $ 280.00

The simple interest accumulated

on a principal of $ 2,800.00

at a rate of 2% per year

for 5 years is $ 280.00.

Answer:

r =14 in

Step-by-step explanation:

120 degrees is one-third of the central angle, 360 degrees.  

Use the area formula A = pi*r^2.  Modifying this to fit the circumstances of this question, we have:

16.75 in^2 = (1/3)(3.14)r^2, or

r^2 = 15.9951, or r^2 = approximately 16.    Then r = 4 in

Answer:

Step-by-step explanation:

simplify:

1/1-x^(b-a)+1/1-x^(a-b)​

[tex]\frac{1}{1-x^{b-a}} + \frac{1}{1-x^{a-b}}\\= \frac{1-x^{a-b} + 1-x^{b-a}}{(1-x^{b-a})(1-x^{a-b})}\\= \frac{1-x^{a-b} + 1-x^{b-a}}{(1-x^{b-a}-x^{a-b}+x^{b-a+a-b})}\\= \frac{1-x^{a-b} + 1-x^{b-a}}{(1-x^{b-a}-x^{a-b}+1)}\\= \frac{2-x^{a-b}-x^{b-a}}{2-x^{b-a}-x^{a-b}}\\= 1\\ \\[/tex]

Step-by-step explanation:

The pentagons remain similar because similarity is not affected when the lengths of a figure are changed. Option d is correct.

Two pentagons are given, 2 units add to each of the sides of both the pentagons. whether the two pentagons are similar or not is to be determined.

Pentagon is defined as a 5 sided polygon have equal lengths of sides and vertices make 72° at the center

Two pentagons are similar if 2 units are added to both the lengths of sides of the pentagon it will not affect their similarities. Because the ratio of the side to 1 pentagon to other pentagon remains the same on all sides.

Thus, the pentagons remain similar because similarity is not affected when the lengths of a figure are changed.

Answer:

A. 6.79

Step-by-step explanation:

4/3.88= 0.97 per can

0.97*7=6.79

Answer:

Option A: $6.79 is the correct answer.

Step-by-step explanation:

Given that:

Cost of 4 cans of tuna = $3.88

Cost of 7 cans of tuna is to be find.

We will find the unit rate.

Unit rate = [tex]\frac{Cost\ of\ cans}{Number\ of\ cans}[/tex]

Unit rate = [tex]\frac{3.88}{4}[/tex]

Unit rate = $0.97 per can

Cost of 7 cans = 7*0.97

Cost of 7 cans = $6.79

Hence,

Option A: $6.79 is the correct answer.

X^2 + 2(30x) + 900

Step-by-step explanation:

You multiply the sides of each square and add them to get the total of the whole square. For the top left square, you multiply x and x. For the top right, you multiply 30 and x. For the bottom left, you multiply 30 and x as well. And for the bottom right, you multiple 30 and 300. Add these together and you get X^2 + 2(30x) + 900.

Answer:

A. $7.50

B. 9.15%

Step-by-step explanation:

Difference of 82 and 74.50 = |82 - 74.50|/((82 + 74.50)/2) = 7.5/78.25 = 0.095846645367412 = 9.5846645367412%

74.50 is a 9.1463414634146% decrease of 82.

Percentage of decrease = |82 - 74.50|/82 = 7.5/82 = 0.091463414634146 = 9.1463414634146%
