Answer:
27.95 and 34.05 are compatible because when you add up the decimals, the equal 0, which makes it easier to add. 27. 95 + 34.05 = 61.00.
Same with 19.37 and 21.63, it adds up to 40.00
The answer to all of this would be 101.00

The equation A=p+prt is ued to find the accumulated amount, A, of an investment with principle, P, a certain interest rate, r, and over time, t. What is the value for r, after the equation is rearranged?
A. r= A+p/ pt
B. r= A-p/ pt
C. r= A-1/ t
D. r= A-p-pt
Answer:
B. r = A-p/pt
Step-by-step explanation:
We can rearrange the equation to make [tex]r[/tex] the subject of the equation:
[tex]A=p+prt[/tex]
[tex]A-p = p+prt-p[/tex]
[tex]A-p = prt[/tex]
[tex]\frac{A-p}{pt} = \frac{prt}{pt}[/tex]
[tex]r = \frac{A-p}{pt}[/tex]
∴ Option B is correct
Hope this helps :)

I don´t get how to solve it please explain
Answer:
B. 16.9
Step-by-step explanation:
Reverse Pythagoreans theorem C^2 - B^2 = A^2 so
7^2 - 5^2 = c^2 and it comes out to
49-25 = 24 the square root of that is 4.9 (rounded)
But we are lookign for the perimeter so
4.9 + 7 + 5 = 16.9

A bottle of 150 vitamins costs $5.25. If the cost varies directly with the number of vitamins in the bottle, what should a bottle of 250 vitamins cost?
Answer:
$8.75
Step-by-step explanation:
Set up a proportion where x is the cost of a bottle with 250 vitamins:
[tex]\frac{150}{5.25}[/tex] = [tex]\frac{250}{x}[/tex]
Cross multiply and solve for x
150x = 1312.5
x = 8.75
So, it will cost $8.75 for a bottle with 250 vitamins

Step-by-step explanation:
Bryan and Yuan started out at their houses and are biking towards each other. Bryan started
out first, and has already gone 5 miles. He bikes at a constant speed of 3 miles per hour.
Yuan just left, and rides at 4 miles per hour. When the boys meet halfway between their
houses, they will continue to the park together. How long will that take? How far will each
boy have ridden?
Answer:
Bryan and Yuan will meet after 5 hours, having traveled 20 miles each.
Step-by-step explanation:
Given that Bryan and Yuan left their homes at different periods of time and at different speeds, to determine how long they will meet and how much distance they will have traveled, the following calculation must be performed:
B = 5 + (3X)
Y = 4X
B = 5 + 3x2 = 11
Y = 4x2 = 8
B = 5 + 3x3 = 14
Y = 4x3 = 12
B = 5 + 3x4 = 17
Y = 4x4 = 16
B = 5 + 3x5 = 20
Y = 4x5 = 20
Therefore, Bryan and Yuan will meet after 5 hours, having traveled 20 miles each.
In the following figure, find the value of x
Answer:
18
Step-by-step explanation:
All the angles added up will equal 180 degrees (recall a straight line has an angle of 180 degrees).
Therefore, you can create the following equation and solve for x:
[tex]2x+3x+2x+3x=180\\10x=180\\x=\frac{180}{10}\\x=18[/tex]
Answer:
x=18
Step-by-step explanation:
equation: 90=2x+3x

Answer:
x = 4
Step-by-step explanation:
Since the rectangles are similar, use a ratio.
15/6 = 10/x
or
6/15 = x/10
I will use 15/6 = 10/x to solve this problem, but both ratios should work to solve this problem.
15/6 = 10/x
Cross Multiply:
6(10) = 15x
Solve:
60 = 15x
x = 4
Let x denote the number of broken pencils in a randomly selected 50-count box from a local office supply store. The variable x has the
following probability distribution:
a)
0.82; if we were to select many boxes of pencils randomly, the number of broken pencils would typically vary about 0.82 from the
mean
b)
0.31; if we were to select many boxes of pencils randomly, we would expect about 0.31, on average, to contain broken pencils
c)
0.65; if we were to select many boxes of pencils randomly, the number of broken pencils would typically vary about 0.65 from the
mean
d)
0.52; if we were to select many boxes of pencils randomly, we would expect about 0.52 to have no broken pencils
e)0.13; if we were to select many boxes of pencils randomly, we would expect about 0.13, on average, to contain broken pencils
Answer:
0.82

Select all the relations that represent a function.
1. (1, 3), (2, 5), (2, 7) (4,9)
2. (1, 3), (2, 5), (3, 7) (4,9)
3. (1, 3), (1,5), (1, 7) (4, 9)
4. (1,3), (2, 3), (3, 3) (4, 3)
5. (1, 2), (2, 5), (2, 1) (4, 5)
Answer:
1. (1, 3), (2, 5), (2, 7) (4,9) No
2. (1, 3), (2, 5), (3, 7) (4,9) Function
3. (1, 3), (1,5), (1, 7) (4, 9) No
4. (1,3), (2, 3), (3, 3) (4, 3) Function
5. (1, 2), (2, 5), (2, 1) (4, 5) No
Step-by-step explanation:
If you see the same x-coordinate more than once in a relation, then that relation is not a function.
1. (1, 3), (2, 5), (2, 7) (4,9) The 2 is used more than once as a x-coordinate. Not a function.
2. (1, 3), (2, 5), (3, 7) (4,9) All x-coordinates are different. Function.
3. (1, 3), (1,5), (1, 7) (4, 9) The 1 is used more than once as an x-coordinate. Not a function.
4. (1,3), (2, 3), (3, 3) (4, 3) All x-coordinates are different. Function.
5. (1, 2), (2, 5), (2, 1) (4, 5) The 2 is used more than once as a x-coordinate. Not a function.

If you can't read my writing, this is the questions:
'Calculate the perimeter of this sector.
Give your answer in terms of pi.'
Answer:
Perimeter of the sector = (36 + 8π) cm.
Step-by-step explanation:
Formula to find the of an arc of the circle is,
Length of the arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]
Here, θ = central angle formed by the arc
r = radius of the circle
Therefore, length of the arc given in the picture = [tex]\frac{80}{360}(2\pi) (18)[/tex]
= 8π cm
Perimeter of the sector = Sum of all sides of the sector
= Length of radius + length of the arc + length of radius
= 18 + 8π + 18
= (36 + 8π) cm
Perimeter of the sector is (36 + 8π) cm.

What is the value of x for the equation 4x – 2y = 6 if y= -3?
Answer:
x = 0
Step-by-step explanation:
Let's divid both sides of the equation by 2 first, so we don't have as much work to do in the next step:
[tex]4x-2y=6\\2x-y=3[/tex]
Substituting -3 for y:
[tex]2x-(-3)=3\\2x+3=3\\2x=0\\x=0[/tex]
