Answer:
91 scores
Step-by-step explanation:
Let x be the score meg get on fourth test,
Let the total sum of the scores in four test = 45 + 48 + 56 + x (91) = 149 + x
149 + x = 240
x = 91
So to put this in easier words, (45+48+56+91)/4=91
Hence, she should get 91 scores on the fourth test to get an average score of 60.
I hope this helps you, Enjoy!

Answer:
115ft
Step-by-step explanation:
Think of it as two rectangles. One rectangle would be 10ft long and 13-5 or 8ft wide. The other rectangle would be 5ft long and 10-3 or 7 ft wide. Find the area of the two rectangles and add them. Rectangle 1= 10•8 or 80ft. Rectangle 2= 5•7 or 35ft. 80+35=115ft. Juan would need at least 115ft of rubber flooring.

7th grade math pls help me
Answer:
I think the answer might be true
Step-by-step explanation:
Supplementary angles add up to 180 degrees. When the angles are placed next to each other, they should add up to 180. Let's try it... 130+50 = 180. Therefore, these angles are supplementary.
Also, for extra help, 180-degree angles make a straight line, like this one. When you get stuck, you can always refer to websites such as Khan Academy for practice and explanations. (https://www.khanacademy.org)

Find the volume of the prisms. Show work!
1. Answer = About 1451.42 m³
First, we need to find the volume of the cube:Formula: πr²hVolume = π * 3² * 50 = 1413.72 m³Second, we need to find the volume of the cone:Formula: (πr²h)/3Volume = π * 3² * 4 = 37.69 m³Third, we need to add these two volumes to find the total volume of the figure.1413.72 m³ + 37.69 m³ = 1451.42 m³.2. Answer = 960 m³
Formula: (1/2(b*l)) * 20First, we need to find the area of the base (1/2 * b* l).1/2 * 8 * 12 = 48.Second, we need to multiply the area of the base by the height to get the volume.B * h = 48 * 20 = 960 m³.Grace was given the description “three less than the quotient of a number squared and nine, increased by eight” and was asked to evaluate it when n = 6.

Find the TWO integers whos product is -12 and whose sum is 1
Answer:
[tex] \rm Numbers = 4 \ and \ -3.[/tex]
Step-by-step explanation:
Given :-
The sum of two numbers is 1 .The product of the nos . is 12 .And we need to find out the numbers. So let us take ,
First number be x Second number be 1-x .According to first condition :-
[tex]\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}[/tex]
Hence the numbers are 4 and -3
Step-by-step explanation:
[tex]integers \: = x \: and \: y \\ then \: x \times y = - 12 ....(1)\\ x + y = 1.....(2) \\ x = 1 - y.....(3) \\ put \: (3 )\: in \: (1) \\ then \: (1 - y) \times y = - 12 \\ y - {y}^{2} + 12 = 0 \\ {y}^{2} - y - 12 = 0 \\ factorise \\ {y}^{2} - 4y + 3y - 12 = 0 \\ y( y - 4) + 3(y - 4) \\ (y - 4)(y + 3) \\ y = 4 \: and \: - 3 \\ thank \: you[/tex]
From the table, the ratio of white socks to brown socks is 9/8
Select two ratios equivalent to the ratio of white socks to brown socks.
A) 35/32 B) 40/46 C) 36/33 D) 45/40
Answer:
D
Step-by-step explanation:
To find an equivalent ratio it must be multiplied or divided by the same number.
I multiplied 8 by 5 which got me 40
Then I multiplied 9 by 5 which got me 45
This means the equivalent ratio is 45/40

Answer:
Step-by-step explanation:
1) x +22.5 = 49.25
Subtract 22.5 from both sides
x + 22.5 - 22.5 = 49.25 - 22.5
x = 26.75
Checking: LHS = x + 22.5 = 26.75 + 22.5 = 49.25 = RHS
2) 37.2 = n - 12
Add 12 to both sides
37.2 + 12 = n - 12 + 12
49.2 = n
n = 49.2
3) 55t = 176
Divide both sides by 55
[tex]\frac{55t}{55}=\frac{176}{55}\\\\t = 3.2[/tex]

Answer:
Part A
Its Q3 ⇒ 9Part B
Its data between Q1 and Q3 ⇒ between 5 and 9Part C
Its data to the left from Q1 ⇒ 5Benny, and his three friends went to lunch. The bill, before sales tas and tip, was $37.50. A sales tas of 8% was added. The group then tipped 18% on the amount before the sales tax was added. What was the total amount the group paid, inclouding tax and tip?
Hello! I believe that I have the answer.
My answer: The total amount was $47.79.
8% of $37.50 is $3. $37.50 + $3 = $40.50.
18% of $40.50 is $7.29. $40.50 + $7.29 = $47.79.
I hope that helps! Please let me know if my answer is incorrect.
