Step-by-step explanation:
Okay so the shape has an area of 60 square inches. The formula for the area of a triangle is A = b*h where A = area, b = base, and h = height
So we are given the value for A (60)
We are given the value for height (10)
So we just need to find the value of the base
So let's set this up as an equation. Input the given values into the area for triangle formula
A = B*h
60 = B * 10
So we need to solve for B. To do that we need to get B alone on one side of the = sign. B is being multiplied by 10 so do the opposite and divide both sides by 10
60 divided by 10 = 6
10 divided by 10 = 1 (don't actually put a 1 down, just drop it)
So we are left with
6 = B
So the base is 6 square inches. To test, put it in the equation:
A = B*h
60 = 6*10
60 = 60

what is the remainder of 14952 divided by 41 plzzzzz help ASAP will give brainiest answer
Answers
Answer: 364 with a remainder of 28
Step-by-step explanation:
14952/41
41 goes into 149 3 times
149 - (41 *3)
149 - 123 = 26
41 goes into 265 6 times
265 - (41*6)
265 - 246 = 19
41 goes into 192 4 times
192 - (41*4)
192 - 164 = 28
So 14952/41 = 364 with a remainder of 28

A school has a track that is made up of a rectangle with two semicircles at each end, as pictured. The perimeter of the track, P, is 395 m. The rectangular part of the track will be covered with grass. The grass comes in pieces that each have an area of 1.35 square metres. Determine the minimum number of pieces of grass required to cover the rectangular part of the track.
Answers
Answer:
4502 pieces of grass
Step-by-step explanation:
The radius of the semicircle is 36 meters, so its perimeter is:
Perimeter = pi * radius = 113.097 m
The perimeter of both semicircles is 2 * 113.097 = 226.194 m
So if the total perimeter is 395, the length of the rectangle is:
395 = 226.194 + 2*length
2*length = 168.8
length = 84.4 m
The width of the rectangle is 2 times the radius of the semicircle, so:
width = 2 * 36 = 72 m
Then the area of the rectangle is:
Area = length * width = 84.4 * 72 = 6076.8 m2
To find the number of grass pieces, we divide the rectangle area by the grass piece area:
number of pieces = 6076.8 / 1.35 = 4501.33 pieces
So we will need 4502 pieces to cover the rectangular area.
An artist can sell 20 compies of a painting for $100 each, but for each additional copy he makes the value of each painting will go down by 1 dollar. How many copies should he make to maximize the profit?
Answers
Answer:
40 copies for $3000
Step-by-step explanation:
First: The Equation
y=(20+x)(100-x)
This shows how for every new painting, the price will go down.
y=2000+80x-x²
Convert it to standard form: ax²+bx+c
You can now choose to graph it or find the vertex form. For the limit of time, I will just use a graph.
The vertex, (40,3000), is your answer, where the x value is the number of paintings and the y value the money made.

Kevin says that lines p and m will eventually intersect.
Lines A and B intersect. Plane A contains lines p, m, and n. Line n is horizontal on the plane. Lines p and m are both going in the same direction and are identical. Plane B contains vertical line l which forms a right angle with line n.
Is Kevin correct?
No, because they are non-coplanar.
No, because they are parallel.
Yes, because they are perpendicular.
Yes, because they are coplanar.
Answers
Answer:
No, because they are parallel.
Kevin says that lines p and m will eventually intersect. The statement is incorrect because lines p and m are parallel.
What are parallel and perpendicular lines?Lines in a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other. Perpendicular lines are those that cross at a straight angle of 90 degrees.
It is given that lines A and B intersect. Plane A contains lines p, m, and n. Line n is horizontal on the plane. Lines p and m are both going in the same direction and are identical. Plane B contains vertical line l which forms a right angle with line n.
In the image attached with the answer below it is observed that the two lines p and m are in the same plane and are parallel to each other.
Therefore, the statement given by Kevin is incorrect.

Step-by-step explanation:
Some students are trying to write an expression with fewer terms that is equivalent to 8 - 3(4 - 9x). Noah says, "I worked the problem from left to right and ended up with 20 - 45x." 8 - 3(4 - 9x) 5(4 - 9x) 20 - 45x Lin says, "I started inside the parenthesis and ended up with 23x." 8 - 3(4 - 9x) 8 - 3(-5x) 8 + 15x 23x Jada says, "I used the distributive property and ended up with 27x - 4." 8 - 3(4 - 9x) 8 - (12 - 27x) 8 - 12 - (-27x) 27x - 4 Andre says, "I also used the distributive property, but I ended up with -4 - 27x." 8 - 3(4 - 9x) 8 - 12 - 27x -4 - 27x Do you agree with any of them? Explain your reasoning.
Answers
Answer: Yes I agree with Jada. His approach is correct.
Step-by-step explanation: The question requires the student to write an equivalent equation with fewer terms. Nonetheless, this does not prevent applying a mathematically correct approach.
(1) Noah is wrong and the reason is that the initial step is mathematically incorrect. The expression on the right hand side reads 3(4 - 9x), therefore starting with "8 - 3" is very wrong. The right step was to take one side which is 8 and take the other side which is 3(4 - 9x).
(2) Lin is wrong and the reason is that she started inside the parenthesis and this also is mathematically incorrect. The digits inside the parenthesis are "not like terms" and hence calculating 4 - 9x = -5x is very incorrect (the same way you cannot correctly calculate 500 metres minus 200 inches. You must make sure they are both in meters or in inches, that is both must be like terms).
(3) Jada is very correct in using the distributive property and ended up with the only correct solution. The digits on the right hand side of the expression was solved first and that resulted in -12 + 27x. The reason being that the number outside the parenthesis which is -3, multiplied both digits inside the parenthesis. The minus sign had a major effect, and after simplifying the right hand side the expression now becomes;
8 - 12 + 27x
Since the like terms are 8 and 12, you can simplify further to become
- 4 + 27x OR the expression can be rearranged as 27x - 4
(4) Andre is not correct and the reason is that although he used the distributive property, he made a slight mistake while solving for the right side of the expression. What Andre did was
-3(4 - 9x)
-12 - 27x
Remember that when a negative value multiplies another negative value the answer is positive. Therefore -3 times -9x should have been +27x, just like Jada did as shown above.
From that point onward, his answer would be incorrect.

A store that normally sells a docking station for an iPod for $128 is having a sale. Everything is discounted 35%. What is the sale price of the docking station?
Answers
Answer:
$83.2
Step-by-step explanation:
price= $128
sale discount= 35%
sale price= $128- 35%= $128*0.65= $83.2
Answer:
83.2$
Step-by-step explanation:
Given:
A docking station for an iPod cost 128$.
The discount percent is 35%.
Solve for:
The sale price of docking station.
Solution:
The amount of discounted price (DP) could be calculated by formula:
DP = original price x discount percent
= 128 x 35%
= 128 x 35/100
= 44.8$
=> The sale price (P) is:
P = original price - discounted price
= 128 - 44.8
= 83.2$

area of a semicircle with a radius of 3
Answers
Answer: 9π/2
Step-by-step explanation:
A semicircle is half of a circle. Therefore, you must divide the area by 2.
[tex]A=\frac{\pi r^2 }{2}[/tex]
Since we know the radius, we can directly plug it into the formula.
[tex]A=\frac{\pi (3)^2}{2} =\frac{9\pi }{2}[/tex]
Since the problem stated to give the answer in terms of π, 9π/2 is our answer.
Answer:
[tex]\frac{9\pi }{2}[/tex] cm²
Step-by-step explanation:
The area of a semicircle can be expressed by the formula [tex]\frac{\pi r^{2} }{2} = A[/tex].
When you plug in the radius, you get [tex]\frac{\pi 3^{2} }{2} = \frac{\pi 9}{2} = \frac{9\pi }{2}[/tex].

Step-by-step explanation:
She is working on "x" cases, then she adds 8 more to that number, therefore it is "x + 8" and we also know that the total number of cases she's working is more than 29, in other words, it is greater than 29. With this in mind we can create the following inequality:
[tex]x + 8 > 29[/tex]
