Which expression has a value of 35 when p = 7?

Answers

Answer:

If you substitute 7 in for each equation you will see that the answers are either 7, 38, or 32, which are not 35. But when you substitute 7 in for B, 5(7), and multiply it out you get 35. I hope this helps :)

Triangle formula:

Deposited 3,000$ and it earned 300$ in simple interest after 5 years what’s the interest rate

Answers

Answer:

The interest rate is 2%

Step-by-step explanation:

Simple Interest

Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.

The interest earned is calculated as follows:

I=P.r.t

Where:

I = Interest

P = initial principal balance

r = interest rate

t = time

The principal is P=$3,000 and it earned I=$300 in t=5 years. Thus the interest rate can be calculated by solving for r:

[tex]\displaystyle r=\frac{I}{P.t}[/tex]

[tex]\displaystyle r=\frac{300}{3,000*5}[/tex]

[tex]\displaystyle r=\frac{300}{15,000}[/tex]

r = 0.02

The interest rate is 2%

which images shows a reflection

Answers

I'll Give You Some Hints:

Let's Look at C.

In C, the triangle is translated 2 units to the right. Which means that it cannot be a reflection.

Let's Look at B.

In B there is a sideways triangle. That means it's a Rotation. Which means it's not Reflected.

Lastly, Let's Look at A.

To get from the original triangle to the triangle in A, you have to reflect twice. Once along a vertical line, and then along a horizontal line.

[Easy Question] Answer this with evidence of the answer that you provided with me!

Answers

Answer:

To start you will find the area as if it was a rectangle. To do that you have to do 8x12. 8x12 = 96, but to find the area of a triangle you take the area of the rectangle and divide it by 2. 96 divided by 2 is equal to 48.

There are other methods of solving this but I think this is the easiest way!
