.Edward deposited $9,500 into a savings account 3 years ago. The simple interest rate is 4%. How much money did Edward earn in interest?

Answers

Answer:

first, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year.

Solving our equation:

A = 6000(1 + (0.03 × 4)) = 6720

A = $6,720.00

The total amount accrued, principal plus interest, from simple interest on a principal of $6,000.00 at a rate of 3% per year for 4 years is $6,720.00.

Hii :)

We know that there are 2 boys, so we should divide 2 by 43. But first..

We need to add the total amount the boys spent together, then subtract,then divide

13+5=18.

The boys spent a total amount of 18 cents.

Next, we need to subtract 18 by 43.

43-18=25.

So, if we were to spilt the 25 evenly, or divide by 2, the answer would be 12.5 cents. But, we need to find what they had to start with.

43 divided by 2 is 21.5. So each boy had 21.5 cents to start with.

Answers

Answer:

409[tex]cm^{2}[/tex]

Step-by-step explanation:

The area of the box wuld be c times d which is 15 times 17 which is 255.

the area of the triangle is [tex]\frac{1}{2}\\[/tex] (base x height) = [tex]\frac{1}{2}\\[/tex](28 x 11) = 14 x 11 = 154

154 + 255 = 409. area of 2D shape's unit is squared, so 409 [tex]cm^{2}[/tex]

B.409
you find the area of the rectangle which is 15 x 17 = 255
then you find the area of the triangle which is
(28 x 11)/2 =154
abs 154 + 255 = 409

Write in slope-intercept form an equation of the line that passes through the given points.

(−1,4),(3,8)

Answers

answer: y = x + 5

step by step explanation:

Answer:

y = x + 5

Step-by-step explanation:

Slope (m) formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{8-4}{3-(-1)}\\\\m=\frac{8-4}{3+1}\\\\m=\frac{4}{4}\\\\m=1[/tex]

y = mx + b

y = 1x + b  OR y = x + b

(-1, 4)

y = x + b

4 = -1 + b

+1   +1

5 = b

y = x + 5

Check your answer using y = x + 5 and (3, 8):

y = x + 5

8 = 3 + 5

8 = 8

This statement is true

Therefore, our final answer is, y = x + 5.

Hope this helps!
