Jerry borrowed $4,000 for 5 years at 6% simple interest rate. How much interest is that?

Answers

Use I = Prt
where
I = Interest
P = Principal = $4,000
r = interest rate = 6% = 0.06
t = time = 5 years

I = $4,000 × 0.06 × 5 = $1,200

Jerry borrowed $1,200 for 5 years. Hope this helps!

In this question one has to look forward to the information's already given. Based on those given information's the answer to the question can be easily determined.
Principal amount = $4000
Time for which money is borrowed = 5 years
Rate of interest = 6%
Then
Amount of Interest = Principal * Rate * Time
   = 4000 * 6% * 5
   = 4000 * 6/100 * 5
       = 40 * 30
   = 1200 dollars
So the amount of interest that needs to be given is 1200 dollars. I hope the naswer and the procedure is clear enough for you to understand.

What’s the answer to this question

Answers

Answer:

The length is 65 cm and the width is 12 cm

Step-by-step explanation:

A = lw = 780

P = 2 (l+w) = 154

The length is 5 more than 5 times the width

l=5w+5

P = 2 (l+w) = 154

Divide each side by 2

2 /2 (l+w) = 154/2

l+w = 77

Substituting l = 5w+5

5w+5 +w = 77

6w+5 = 77

Subtract 5 from each side

6w +5-5 = 77-5

6w = 72

Divide each side by 6

6w/6 = 72/6

w = 12

Now lets find l

l = 5w+5

l = 5(12)+5

l = 60+5

l = 65

PLEASE FACTOR these POLYNOMIALS and EXPLAIN HOW
1. 12x - 3x^2
2. 20 - 240x^2

Answers

Answer:

1. 3x(4-x)

2. 20(1-12x^2)

Step-by-step explanation:

1. Both of the monomials have an x and can be divided by 3. You can factor out 3x, getting the equation I wrote out on the answer part.

2. Both of the monomials can be divided by 20, so you can once again factor out 20, getting the equation I wrote out on the answer part.

(-t^4 – 5t^3– 10t^2) + (9t^3+ 3t^2– 1) =

Answers

According to given question, The simplified polynomial in standard form is: $-t^4 + 4t^3 - 7t^2 - 1$

To add the two polynomials and simplify, we'll combine like terms:

$(-t^4 - 5t^3 - 10t^2) + (9t^3 + 3t^2 - 1)$

In mathematics, a polynomial is an algebraic expression consisting of variables (also known as indeterminates) and coefficients, combined using addition, subtraction, and multiplication operations. The variables are raised to non-negative integer powers, and the coefficients are constants that multiply the variables. The term "polynomial" comes from the Latin words "poly" (meaning "many") and "nomial" (meaning "term").

Step 1: Combine the terms with $t^4 and t^3:$

$(-t^4) + (9t^3 - 5t^3) - 10t^2 + 3t^2 - 1$

Step 2: Combine the $t^3$ terms and the $t^2$ terms:

$(-t^4) + (4t^3) - 7t^2 - 1$

So the simplified polynomial in standard form is:

$-t^4 + 4t^3 - 7t^2 - 1$
