Brian invests £1850 into his bank account. He receives 2.7% per year simple interest. How much will Brian have after 3 years? Give your answer to the nearest penny where appropriate.

Answers

Answer:

£1999.85

Step-by-step explanation:

A = P(1 + rt)

Where:

A = Amount after t years

P = Initial amount invested = £1850

r = Interest rate = 2.7%

t = Time in years = 3 years

Calculation:

First, converting R percent to r a decimal

r = R/100 = 2.7%/100 = 0.027 per year.

Solving our equation:

A = £1850(1 + (0.027 × 3))

A = £1999.85

Therefore, Brian will have £1999.85 after 3 years.

Hakeem went shopping for a new pair of sneakers because of a sale. The store was offering a 40% discount. What number should he multiply the prices on the tags by to find the price he would have to pay, before tax, in one step?

Answers

Answer: 60% or 0.6

Step-by-step explanation:

A discount simply means the amount that is deducted from the normal cost of a good or service.

In the question above, the store was offering 40% as discount, this means that he'll only pay 60% of the price of the good. Note that (100% - 40% = 60%).

Therefore, the number that he should multiply the prices on the tags by to find the price he would have to pay will be 60% = 0.6.

Answers

Answer: Choice A)  8x+2 = 14x-76

==============================================================

Explanation:

Since lines A and B are parallel, this makes the corresponding angles (8x+2) and (14x-76) to be equal.

So the equation we need to solve is 8x+2 = 14x-76

If you solve that equation, you should end up with x = 13. Plugging x = 13 into either 8x+2 or 14x-76 would lead to the result of 106. So each corresponding angle is 106 degrees.

8x+2=14x-76

Simplified Expression:

Answers

Answer:

Step-by-step explanation:

So you are combining the numbers that look alike practically..

They are asking for how many like term, so you would put how many numbers you see that are different.

-12x - 4x - 72 + 10y^3

-16x - 72 + 10y^3

That is as far as you could go.

There are 3 numbers that look different.

When I say this I mean that one number has no variable, one number has a variable, and another number has a variable and it’s cubed.

So that would be 3 like terms.

And for the simplified form, it’s

-16x - 72 + 10y^3
