3% is the interest rate. Using the formula I=PRT, you can simply derive the rate by putting the given numbers in.
I = 450P = 3,000R = ?T = 5 Years
The equation now goes,450 = 3,000 * R * 5450 = 15,000 * R450/15,000 = R0.03 = R
 multiply it by 100,
R = 3%

David has 85 white eggs and 28 brown eggs. He puts 6 eggs into each tray and fills as many trays as he can. How many eggs are le
Murljashka [212]

Answer:

5 eggs are left over.

Step-by-step explanation:

Computers love this question. They have a built in command called mod which will give the answer in one line.

L = (85 + 28) mod 6: Print L

Humans have a little tougher time with it. We do it like this

Add 85 and 28 = 113

Divide by 6

113 / 6 = 18.8333333

What is left over is 0.833333333. But what does that mean, and how do you get rid of it?

Answer Number of Trays: The 18 is easily explained. He can fill 18 trays.

But we still have 0.83333333 to deal with.

The simplest way is to multiply that by 6.

6 * 0.833333333 = 5

The answer is 5

What is a quadratic polynomial function with zeros 3 and -3?​
Lemur [1.5K]

Answer:

f(x) = x² - 9

Step-by-step explanation:

Given x = a is a zero of the polynomial f(x) then (x - a) is a factor

Given zeros are x = 3 and x = - 3, then corresponding factors are

(x - 3) and (x - (- 3) ), that is

(x - 3) and (x + 3)

The function is then the product of the factors, that is

f(x) = (x - 3)(x + 3) ← expand using FOIL

f(x) = x² - 9

(3n-2)(4n+1)<br> how do i solve this by factoring?
Anni [7]

Answer:

12n^2-5n-2

The expression (3n-2)(4n+1) can be factored with the Distributive Property. It cannot be factored with a Least Common Multiple (LCM), for instance, because the terms within each set of parentheses are completely simplified.

Step-by-step explanation:

Part I

.1. (3n-2)(4n+1)\\2. F.O.I.L.: 12n^2+3n-8n-2\\3. Simplify: 12n^2-5n-2\\

Good luck to you!
