If the simple interest on $7,000 for 5 years is $2,800, then what is the interest rate?
Answer:
8%
Step-by-step explanation:
Solving our equation
r = 2800 / ( 7000 × 5 ) = 0.08
r = 0.08
converting r decimal to a percentage
R = 0.08 * 100 = 8%/year
The interest rate required to
accumulate simple interest of $ 2,800.00
from a principal of $ 7,000.00
over 5 years is 8% per year.

4(r - 3k) = r - 5k
Solve for r
Answer:
r= 7k/3
Step-by-step explanation:
Answer:
r=7k/3
Step-by-step explanation:
4r-12k=r-5k
4r=r-5k+12k
4r=r+7k
4r-r=7k
3r=7k
r=7k/3
Evaluate 3/7r + 5/8s when r= 14 and s= 8
Answer:
11
Step-by-step explanation:
Step 1:
3/7r+5/8s
Step 2:
So u multiply 3/7 by 14
3/7 x 14= 42/7= 6
Step 2.5:
Now u multiply 5/8 by 8
5/8 x 8= 40/8= 5
Step 3:
6+5=11

Answer:
$22843.75
Step-by-step explanation:
I'm assuming that $18.275 is $18,275
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 18275 × 0.05 × 5 = 4568.75
I = $ 4,568.75
The simple interest accumulated
on a principal of $ 18,275.00
at a rate of 5% per year
for 5 years is $ 4,568.75.
Answer:
$95943.75
Step-by-step explanation:
(assuming that its actually 18,275 and not 18.275)
18,275*1.05(5)
the amount borrowed (18,275)* the interest rate (1.05) *the number of years (5)

Special Cases
8x+3-10x=2(x-2)+3
Answer:
x = 1
Step-by-step explanation:
8x + 3 - 10x = 2(x - 2) + 3
Distribute the 2
8x + 3 - 10x = 2x - 4 + 3
Combine like terms
-2x + 3 = 2x - 1
Add 1 to both sides
-2x + 4 = 2x
Add 2x to both sides
4 = 4x
Divide both sides by 4
x = 1
if you bought a stock last year for a price of $120 and it has gone down 10% since then how much is the stock worth now
Answer:
$108
Step-by-step explanation:
Since $120 is divisible by ten, we can just simply do 120/10, which is twelve. So, 10% of $120 is $12. $120 - $12 = $108

Consider the following statement. If n is divisible by 6, then n is divisible by 2 and n is divisible by 3.
Negation
a. n is divisible by 6 and either n is not divisible by 2 or n is not divisible by 3.
b. If n is not divisible by 2 or n is not divisible by 3, then n is not divisible by 6.
c. If n is divisible by 2 and n is divisible by 3, then n is divisible by 6.
d. If n is not divisible by 6, then n is not divisible by 2 or n is not divisible by 3.
e. If n is not divisible by 6, then n is divisible by 2 and n is divisible by 3.
Answer:
b. If n is not divisible by 2 or n is not divisible by 3, then n is not divisible by 6.
Step-by-step explanation:
Division by Six
A number is divisible by six if it is divisible by both 2 and 3.
Negation:
If the number is not divisible by either 2 or 3, it is not by 6. So the answer is given by option b.

You pick a marble from this bag. What is the probability you will choose either a plain black or plain white marble? Simplify your answer.
Answer:
50% chance for both
Step-by-step explanation:
If its two marbles then you have a 50% chance of picking up either the black or white. If four marbles are in the bag it would be 25%, if 10 then you have 10% and so on.
If you pick a marble from this bag. The probability you will choose either a plain black or plain white marble will be 0.5.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
It is given that, a person has to pick a marble from this bag.
We have to find the probability you will choose either a plain black or plain white marble
The probability that you'll select a basic black or plain white marble,
P=favourable outcome / total outcome
P=(either plain black or plain white marble) / 2
P=1/2
P=0.5
Thus, if you pick a marble from this bag. The probability you will choose either a plain black or plain white marble will be 0.5.

Guys help me with this question please
Answer:
2/7
Step-by-step explanation:
From 8 am to 3 pm, there are 7 hours, and the price changed $2 (52 - 50 = 2)
In order to find the Change in price per hour, divide the total price change by the number of hours. (in most questions with the word "per", it is a division problem)
2$ / 7hrs = 2/7 dollars per hour
