Answer:

No error

Step-by-step explanation:

Ling tried to solve an equation step by step.

Step 1.

-2q + 11 = -32

Step 2.

Subtract 11 from both sides,

-2q + 11 -11 = -32 -11

-2q = -43

Step 3.

Dividing both sides by 2,

q = 21.5

Hence, the calculation has no error.

Please help with this problem
aleksley [76]

Your answer would be 19 and 20.

To solve this, you need to first think about perfect square numbers, and which ones are the closest to 375. This is because perfect squares will always get square rooted back to a whole number, so therefore the ones around 375 would be the closest whole numbers.

Now, 400 is one of the easier to remember square numbers. It is 20 squared. 375 is pretty close to 400, however its slightly lower. So now, let's look at the closest perfect square that's less than 400: 19^2, or 361.

375 is between 361 and 400, so therefore it is between the square root of 361 and 400, or 19 and 20.

Good luck!

8. The initial value of an investment is $12,000. If the investment earns an annual interest rate of 2.2%, what is its value in
amm1812

Answer:

$14,917.30

Step-by-step explanation:Step 1: To calculate your interest rate, you need to know the interest formula I/Pt = r to get your rate. Here,

I = Interest amount paid in a specific time period (month, year etc.)

P = Principle amount (the money before interest)

t = Time period involved

r = Interest rate in decimal

Step 2: Once you put all the values required to calculate your interest rate, you will get your interest rate in decimal. Now, you need to convert the interest rate you got by multiplying it by 100. For example, a decimal like .11 will not help much while figuring out your interest rate. So, if you want to find your interest rate for .11, you have to multiply .11 with 100 (.11 x 100).
