answer is:
Circum: 25.13274 cm^2
Area: 50.26548 cm^2
Step-by-step explanation for the CIRCUMFERNCE ONLY:
Original equation for the circumference of a circle:
C=2(pi)r
We will use 3.14 as pi
We know that the diameter of a circle is 2 times the radius, so in order to find the radius all we have to do is divide the diameter by 2.
8/2 = 4
So now we know what the radius is equal to.
4
So now just plug in your numbers to the original equation
2 X (3.14) X 4
25.13274
If we were to round up the answer would be
25.13
Hope this helps!

A sport store pays its wholesaler $40 for a baseball bat, and then sells it to a customer for $76. What is the markup rate?
Answers
Answer:
Markup 90%
Step-by-step explanation:
If $40 is 100% of the price
then
$76 is ..........x
Cross multiplication
40(x) = 76(100)
40x = 7600
Divide by 100
x = 190
190% = 100% + 90%
That means that the price is the whole price(100%) plus 90%
so the markup is 90%
ANOTHER WAY:
The difference in prices is $76-$40=$36. So, we need to find what percentage of 40 is 36.
We do this by dividing: 36/40=0.9, which is 90%. So, the markup is 90%.

Hy=
v
Answers
Answer:
x = 18 , y = 15
Step-by-step explanation:
Given the 2 equations
3x - 2y = 24 → (1)
x + 2y = 48 → (2)
Adding the 2 equations term by term will eliminate the y- term
4x + 0 = 72
4x = 72 ( divide both sides by 4 )
x = 18
Substitute x = 18 into either of the 2 equations and solve for y
Substituting into (2)
18 + 2y = 48 ( subtract 18 from both sides )
2y = 30 ( divide both sides by 2 )
y = 15

Answers
Answer:
Step-by-step explanation:
So you are combining the numbers that look alike practically..
They are asking for how many like term, so you would put how many numbers you see that are different.
-12x - 4x - 72 + 10y^3
-16x - 72 + 10y^3
That is as far as you could go.
There are 3 numbers that look different.
When I say this I mean that one number has no variable, one number has a variable, and another number has a variable and it’s cubed.
So that would be 3 like terms.
And for the simplified form, it’s
-16x - 72 + 10y^3

What is the Pythagorean Theorem used for right triangles
Answers
Answer:
The Pythagorean theorem consists of a formula a^2+b^2=c^2 which is used to figure out the value of (mostly) the hypotenuse in a right triangle. The a and b are the 2 "non-hypotenuse" sides of the triangle (Opposite and Adjacent).
Answer:
Step-by-step explanation:
Used t find missing side angles when two sides are present. For example, if you have a short leg and a long leg, you can use the Pythagorean Theorem to find the hypotaneus and vse versa, using it to find the short or long leg if the other two are given.

The perimeter of a rectangular
Sheet is 120 cm. If the length is 40 cm, find its breadth.
Also find its area.
Answers
Answer:
Breadth = 20 cm
Area = 800[tex]cm^{2}[/tex]
Step-by-step explanation:
Perimeter = 120 cm
length = 40 cm
Perimeter = 2 ( L + B )
L - length B - Breadth
120 = 2 ( 40 + B )
120 = 80 + 2B
2B = 120 - 80
2B = 40
B = [tex]\frac{40}{2}[/tex] = 20 cm
Breadth = 20 cm
Area of a reactangle = Length × Breadth
= 40 × 20
= 800[tex]cm^{2}[/tex]

paz and her scout troop makes 325 granola bars for a fundraiser. four granola bars are put in each bag. paz says that there will not be any left over. find and correct her mistake.
Answers
Answer:
Her mistake was in how many bags would be able to equally hold 4 bars.
325/4 is 81.25, which would mean there needs to be 82 bags, in which you wouldnt be able to hold 4 each equally.
A better option for Paz is to put 5 bars in each bag as 325 is an even multiple of 5. As such would result in the bag count being brought down to 65 bags to evenly hold all of the bars.

Somebody pls!! “Write the equation of the line in fully simplified slope-
intercept form.”
Answers
Answer:
y = 3/5x + 5
Step-by-step explanation:
Slope-intercept form is y = mx + b where m is the slope (rise / run of the line) and b is y-intercept (y value of where the line intersects with the y-axis.
The line is rising up 3 and run to the right 5 and so it's slope is 3/5. The line intersects with the y-axis at a y value of 5 and so it's y-intercept is 5.
Therefore, your answer in slope-intercept form is y = 3/5x + 5.

To find the area, we divide the shape into two parts at approximately the middle line. The top shape is a trapezoid of base length 7 feet and height 6 feet, while the bottom shape is a parallelogram with one side equal to 4 feet.
Area of trapezoid = (7 + 4)/2 x 6
Area of trapezoid = 33 sq ft
Area of parallelogram = 4 x 4
Area of parallelogram = 16 sq ft
Total area = 49 sq ft
Cost = 2.25 x 49
Cost = $110.25
