Answer:
Clare's score was 70.
Step-by-step explanation:
N = 20
M = 30
C = ?
Mean = (Sum of all values)/3
40 = (20 + 30 + c)/3
40 = (50 + c)/3
50 + c = 120
c = 70
Answer:
70
Step-by-step explanation:
Let's think about this backwards. The mean of all 3 points is 40, so that is our answer. We instead of dividing would multiply. We would multiply by 3 'cause that's how many numbers there are. We would get 120. Finally, we would
3
have to subtract. We will do this problem:
20 + 30 = 50
120 - 50 = 70
So, we get our answer of 70!
__
Let's check our work!
20 + 30 + 70 = 120 = 40
3 3
__
Let's explain our work propproperly:
First, I took the mean and multiplied it by three because we have Noah, Mai, and Clare. Next, I added 20 and 30 to get an answer of 70 which is the answer. In conclusion, Clare's points are 70 points.

Answer:
It should be D, [tex]x^4 - 2x^3 + 7x^2 -12x - 4[/tex]
Step-by-step explanation:
Since, the equation given in the question is the factored form of the equation D. It can be solved using FOIL (First Outside Inside Last):
x * x³ = [tex]x^{4[/tex]
x * 7x = 7x²
x * 2 = 2x
-2 * x³ = -2x³
-2 * 7x = -14x
-2 * 2 = -4
This all would add up to ⇒ [tex]x^{4}[/tex] - 2x³ + 7x² + (-14x + 2x) -4
Simplifying the parenthesis further would give the option D as the answer.

A sphere has a radius of 5 feet. Find the volume of the sphere. Leave your answer in terms of pie. Then use 3.14 for pie and round the volume to the nearest 10th. Volume in terms of pie=? Volume in using 3.14=?
The solution is, The Volume is 523.6, of the sphere has a radius of 5 feet.
What is volume?In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
here, we have,
Given,
r = 5 ft
pi = 3.14
Formula
the volume of sphere is:
V = 4/3 * 3.14 * r^3
Solution
V = 4/3 * 3.14 * 5^3
V = 4/3 * 3.14 * 125
V ≈ 523.59878
V ≈ 523.6 m^3
as, we get,
V≈523.59878
and 5 or more raise the score so the 9 makes the 5 into 6 and drop all of the other numbers.
Hence, The solution is, The Volume is 523.6, of the sphere has a radius of 5 feet.

The graph represents the gallons of water (/) per minute (x) dispensed by a shower head. Which statements are correct?
A)
Point (0,0) represents the unit rate,
8)
Point (5, 1) represents the unit rate,
Point (1,5) represents the unit rate.
D)
7.5 gallons of water are used in 1.5 minutes,
Answer:
I'm gonna base this off of gallon being y and minutes x
Step-by-step explanation:
it dosnt say it starts with any water in it and I have no numbers to base this so I'm gonna say that it passes through the origin and unit rate depends on how many gallons a minute just take 2 minutes and 1 gallon right well that would be .5 for unit rate hope this helps you

Find the perimeter and the area of the polygon with the given vertices.
T (2,7), U (2,9), V (5,9), W (5,7)
The perimeter is __ units.
The area is ___ square units.
Answer:
Step-by-step explanation:
TU , UV , VW, TW are the sides
As points T and U have same x-coordinate, length of TU will be given by the difference of y-coordinate
TU = 9 - 7 = 2 units
As points U and V have same y-coordinate, length of UV will be given by the difference of x-coordinate
UV = 5 - 2 = 3 units
As points V and W have same x-coordinate, length of VW will be given by the difference of y-coordinate
VW = 9 -7 = 2 units
As points W and T have same y-coordinate, length of WT will be given by the difference of x-coordinate
WT = 5 - 2 = 3 units
TU = VW = 2 units
UV = WT = 3 units
So, TUVW is a rectangle
Area = length *width = 3* 2 = 6 square units
Perimeter = 3 + 2 + 3 + 2 = 10 units

Twice c is at most 19.
Answer:
2c < 19
Step-by-step explanation:
Its not giving you an exact value of what c is so when you see "at most 19" you would use less than or equal to sign ( < ) but if instead said it "at least 19" you would use a greater than or equal to sign ( > ).

A plumber has a 2-meter length of pipe. He needs to cut it into sections that are 10 centimeters long. How many sections will he be able to cut? (I will give brainliest if you answer first)
Answer:
20 - 10 cm sections can be cut from a pipe of original length 2 m
Step-by-step explanation:
Convert 2 meters to cm:
2 m 100 cm
------ * ---------------- = 200 cm
1 1 m
Next, divide this 200 cm total length by (10 cm/section) to determine the number of sections:
200 cm
--------------------- = 20 sections
10 cm/section
20 - 10 cm sections can be cut from a pipe of original length 2 m

Answer: 4m²-28m+49
Step-by-step explanation:
(2m-7)² can be written as (2m-7)(2m-7).
You would have to multiply it out like this:
2m times 2m=4m² (2x2=4 and mxm=m²)
2m times -7=-14m (2x-7=-14 then put a m on it)
-7 times 2m=-14m
-7 times -7=49
The equation would then look like this:
4m²-14m-14m+49
Then you would have to collect like terms. Like terms are terms with the same variables and powers. It will then look like this:
4m²-28m+49
Hope this helps :)
Name the marked angle in 2 different ways.
The marked angle in 2 different ways will be ∠HLK or ∠KHL and ∠KHL = ∠HLJ - ∠KLJ.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The marked angle in 2 different ways will be given as,
The first way will be
∠HLK or ∠KHL
The second way will be
∠KHL = ∠HLJ - ∠KLJ
The marked angle in 2 different ways will be ∠HLK or ∠KHL and ∠KHL = ∠HLJ - ∠KLJ.
