Answer 1
Answer: 2 1/2
So 2 is a whole number & the 5 is a decimal. When a number is whole (10) it’ll go on the left side of the decimal. With this, because 5/10 is equal to 1/2, it is 2 1/2
Answer 2
Answer:
Fraction: 25/10 Improper Fraction: 5/2 Mixed Number: 2 1/2
Step-by-step explanation:
2.5 as a fraction is 25/10, and when it is simplified it is 5/2. When that is simplified even more to a mixed number, it is 2 1/2

Jill is making a quilt in the shape of a right triangle. The measurement of the diagonal of the quilt is 36 inches long. The width of the quilt is 15 inches long. What is the approximate length?
Answers
Answer:
32.7 in
Step-by-step explanation:
The quilt is in the shape of a right triangle.
Therefore, we have:
- The diagonal represents the hypothenuse of the right triangle
- The width of the quilt represents one of the two sides of the right triangle
We know that for a right triangle, we can use Pythagorean's theorem:
where
L is the length
w is the width
h is the hypothenuse
In this problem,
h = 36 in
w = 15 in
So, the length of the quilt is:

How much must be deposited today into the following account in order to have $35,000 in 7 years for a down payment on a house? Assume no additional deposits are made.
Answers
Answer:
The amount that must be deposited is $ 19973.87.
Step-by-step explanation:
We have a relation between future value present value as:
F= P
F=future value
P=present value
r=rate (as a decimal)
n=number of compounding periods per year
t=number of years
Now,
assume rate as 8%
35000= P
or, 35000= P ×
or, P =
or, P = $ 19973.87
So you must deposit $ 19973.87 today.

. Ifr varies inversely as the cube of s,
and r= 17 when s= 3, find r when s=2.
Answers
Answer:
25.5
Step-by-step explanation:
r varies inversely as s i.e
r & 1/s
r = K/s
K = rs
r = 17, s = 3
K = rs = 17 x 3 = 51
Now we can obtain r when s = 2 as illustrated below:
r = K/s = 51/2
r = 25.5

The frequency of a vibrating guitar string varies inversely as its length.
Suppose a guitar string 0.65 meters long
vibrates 4.3 times per second. What
frequency would a string 0.5 meters long
have?
Answers
Answer:
5.59 per seconds
Step-by-step explanation:
F is inversely proportional to L i.e
F & 1/L
F = K/L
FL = K
But F = 4.3, L = 0.65
K = FL = 4.3 x 0.65
K = 2.795
Now, we can find F when L = 0.5 by doing the following:
F = K/L
F = 2.795/0.5
F = 5.59 per seconds
Answer:5.59 per seconds
Step-by-step explanation:
F is inversely proportional to L i.eF & 1/LF = K/LFL = KBut F = 4.3, L = 0.65K = FL = 4.3 x 0.65K = 2.795Now, we can find F when L = 0.5 by doing the following:F = K/LF = 2.795/0.5F = 5.59 per seconds

What’s the answer for 6x+7-4x=8+7x-26
Answers
Answer:
x=7
Step-by-step explanation:
Add common variables.
(6x-4x)+7= 8+7x-26
2x+7= 8+7x-26
Subtract the least variable to both sides.
2x+7= 8+7x-26
-2x -2x
Now, simplify the equation.
7= (8-26)+5x
7= -18+5x
Add 18 to both sides.
7= -18+5x
+18 +18
Divide both sides by 5 to isolate the variable.
35= 5x
5 5

The time, t, required to complete a job varies inversely with the number of people,
p, working on the job. If it takes 7.125
hours for 8 workers to complete a job, how
many hours will it take if there are 3
workers?
Answers
Answer:
19 hrs
Step-by-step explanation:
t varies inversely with number of people p
t = k/p
If it takes 7.125 hrs for 8 workers to do the job
K = tp
= 7. 125 x 8
= 57
How many hours will it take if there are 3 workers .
Recall t = k/p
t = 57/3
= 19 hrs
Therefore, It’ll take 19 hrs to Complete the job if there are only three workers.
The Split Ends Salon orders 10 cases of hand-made hairbrushes. If it takes 26 hours to produce 4 cases of hairbrushes, how many
hours will it take to produce enough hairbrushes to fill the order?
Answers
Answer:
it would take 65 hours to produce all of the order.
Step-by-step explanation:
1. you already would figure out that 26 hours=4 cases or 6.5 hours per case of hairbrushes.
2. You would figure out that 26+26 is 52 so 52 hours for 8 cases
3. Then you remember u have 8 cases of hairbrushes now. Set up a mental equation where you can solve in your mind: if I need 10 cases, but have figured out I only calculated 8, how much more would I still need to meet the order?
4. After mentally solving the hypothetical problem, you then would conclude you needed 2 more cases from 8 to equal 10.
5. you then divide 26 hours per 4 cases and you get 13 hours for 2 cases.
6. finally you multiply 26+26+13 which you would get 65 as the answer

Answers
Answer:
8
Step-by-step explanation:
because 8 dived by 2 = 4, 4+1 =5
Answer:
8
Step-by-step explanation:
x/2+1= 5
Carry over the 1 to the 5.
x/2= 5-1

Replace x with 8 and calculate.
8/2+1= 5
4+1= 5
Therefore x=8 and the answer is correct.
