How do you get an odd perimeter for a rectangle? If you can, how oils you get a length and a width?

Answers

Answer 1

Answer: An odd perimeter can only happen if either the length or the width is a fraction with 1/2 in it, or both the length and the width have a 1/4 in it.
The length and the width are found using the regular means, but you will have to worry about fractions involved, so it can get kind of messy

5) Rolanda scored 20, 15, and 16 on her first three math quizzes. Jetta scored 16, 19, and 17 on her quizzes. Using e the mean to compare, who has the higher math quiz scores so far?

Answers

Roland; 20+15+16=51, 51÷3= 17
Roland; 17
We divide 3 because it's the total number of grade she got.
Jetta; 16+19+17=52, 52÷3= 17.1
Jetta; 17.1
So, probably Jetta got better grade than Rolanda

Answer: Jetta got better grade than Rolanda

The sum of 8 and 7 , doubled

Answers

When you're talking about sums, that means you are adding. So, you do 8+7=15. The sum of it being doubled, you say? 15x2=30, or 15+15=30. Hope this helped :)

Here is a hint, "sum" is adding up therefore, the question is asking "The number of 8 + 7, then multiplied by 2. 8+7x2 = 30

What is the value of n? 9×27+2×31-28=n

Answers

So,

9*27 + 2*31 - 28 = n

We use PEMDAS.

Multiply from left to right.
243 + 2*31 - 28 = n
243 + 62 - 28 = n

Add or subtract from left to right.
305 - 28 = n
277 = n

How do you put 5/2 on a number line

Answers

Convert 5/2 to a mixed number first:

Divide 5 by 2; 2 will go into five 2 times with a remainder of 1. This means the whole number portion of the mixed number is 2, and the remainder of the fraction is 1; this gives us 2 1/2.

To plot 2 1/2, plot a point halfway between 2 and 3.

By following steps given, you can successfully placed the fraction 5/2 on the number line.

To put the fraction 5/2 on a number line, you can follow these steps:

1) Draw a straight line horizontally on a piece of paper or use a number line chart if available. Make sure the line is long enough to accommodate the desired range.

2) Determine the range you want to represent on the number line. Let's say you want to represent the numbers from 0 to 3.

3) Divide the line into equal segments to match the range you determined.

For example, you can divide the line into four equal segments representing the numbers 0, 1, 2, and 3.

4) Locate the whole number part of the fraction, which is 2 in this case. Place a point or tick mark above the number 2 on the number line.

5) Divide the segment between the whole numbers into equal parts. Since the fraction is 5/2, you need to divide the segment between 2 and 3 into two equal parts.

6) Starting from the point above the number 2, count two equal segments to the right.

Place a tick mark or point at the end of the second segment.

7) Label this point with the fraction 5/2.

If $1200 is deposited in an account that pays 6.5% interest, what is the difference in the amount after 4 years between the amount earned if the principal is compounded annually and the amount earned calculated using simple interest?

Answers

compounded is
$A=P(r+1)^t$ for
P=principal
r=rate
t=time

simplie is
I=PRT
p=principal
r=rate
t=time

comound
P=1200
R=6.5%=0.065
T=4
$A=1200(0.065+1)^4$
$A=1200(1.065)^4$
A=1543.76
I=A-P
I=1543.76-1200
I=343.76

simple
P=1200
r=6.5%=0.065
t=4
I=1200*0.065*4
I=312

compare
compouned=343.76
simplie=312
difference=343.76-312=31.76

the difference is $31.76

the interest would be $312
