A savings account earns 5% simple interest per year. The principal is $1200. What is the balance after 4 years?How do I solve this?

Answers

Answer 1

Answer:

The balance after [4] years is $1440.

What is a expression? What is a mathematical equation? What is the formula to calculate simple interest?

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. The formula to calculate the simple interest is -

I = (P x R x T)

Total amount after interest -

A[t] = P + PRT = P(1 + RT)

We have a savings account that earns 5% simple interest per year. The principal is $1200.

Assume that the balance after [4] years is $x. Then, we can write -

[x] = P(1 + RT)

[x] = 1200(1 + (0.05 × 4)) = 1440

[x] = $1,440.00

Therefore, the balance after [4] years is $1440.

Answer:847 pounds

Step-by-step explanation:

Let $w$ be the weight of the second pumpkin.

Given that weight of first pumpkin is $903$ pounds.

Since we need the weight of the second pumpkin to be minimum,the average weight of the two pumpkins must be just equal to the required weight to win.

Given that the required weight to win is $875$ pounds.

So, $875=(w+903)/(2)$

$1750=w+903$

$w=847$ pounds

Algebra 1 Solving Linear Expressions.What is 9x-6=-3x+30?

Answers

The answer is x=6. 9x-6=3x+30

9x-3x-6=3x-3x+30

6x-6=0 +30

6x-6 + 6= 0 + 30 +6

6x=36

6x/6=36/6

x=6

A paper company produces 2,400 notebooks in 3 days. How many notebooks can it produce in 11 days.PLEASE HELP!!!!

Answers

They can produce 8,800 notebooks in 11 days. To solve this, you make this a unit rate.

2,400 notebooks ÷ 3 days = 800.

800 notebooks × 11 days = 8,800

This is just an elaboration to help you understand more:

To find out how many books can be produced in 11 days, you need to find out how many can be produced in 1 day, hence 2400/3.

2400/3=800 (How many notebooks produced in 1 day)

You then take 800 and multiply it with 11 (the amount of days)
