Step-by-step explanation:
Noah scored 20 points in a game. Mai's score was 30 points. The mean score for Noah, Mai, and Clare was 40 points. What was Clare's score? Show your work.
I need this answer ASAP.
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.
To pass her test, Tori needs to answer at least 65% of the questions correct. If there were 60
questions and she got 42 correct, did she pass? All work MUST be shown to justify your
answer.
Step-by-step explanation:
To obtain score of 80% on entire exam means the student have to answer
(80/100)×80 = 64 correct answers
Student have already answered 75% of the first 60 questions correctly meaning
(75/100)×60=45 correct answers from first 60 questions
Remaining correct answers s/he have to answer
64-45=19
So from remaining 20 questions s/he have to answer 19 correct questions that is
20 × (x/100) = 19
x = 19 ×(100/20)
x = 95%
I need this NOW WHO EVER ANSWERS CORRECTLY RIGHT NOW I WILL MARK BRAINLIEST BUT IF YOU SPAM I WILL REPORT YOU! Find the value of x.

Answer:
B. 1152
Step-by-step explanation:
First you do the base. 24 x 24 is 576. Now you do each triangle. 12 x 24 = 288 and 288 divided by 2 is 144. 144 x 4 = 576. 576 + 576 = 1152.
I hope this helps! <3
Tell whether the angles are complementary or supplementary. Then find the value of x.
the angles are complementary because they add up to 90° because of the red square. x=20
Step-by-step explanation:
4x-5+15=90
4x+10=90 subtract 10 from each side
then you get left with 4x=80
divide 4 from each side then you get left with x=20 and to check just substitute 20 where x is so 4(20)-5= 80-5=75 +15=90.
City A and City B had two different temperatures on a particular day. On that day, four times the temperature of City A was 8° C more than three times the temperature of City B. The temperature of City A minus twice the temperature of City B was −3° C. The following system of equations models this scenario:
4x = 8 + 3y
x − 2y = −3
What was the temperature of City A and City B on that day?
City A was 5° C, and City B was 4° C.
City A was 3° C, and City B was −1° C.
City A was 8° C, and City B was −3° C.
City A was 5° C, and City B was −5° C.
Answer:
City A was 5 and city B was 4
Step-by-step explanation:
Use substitution. Move 2y over so you have x=-3+2y
Plug that into 4x=8+3y
4(-3+2y)=8+3y
-12+8y=8+3y
subtract 3y from both sides
add 12 to both sides
5y=20
20 divided by 5
y=4
then youd plug it into the other equation
x-2(4)=-3
x-8=-3
x=5
therefore the answer is A

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

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

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.
