Example:
Aaron's P.E. class is completing a unit on bowling. So every Friday afternoon for the last three weeks, they have bowled one game at a nearby bowling alley. His scores have been 121, 147, and 96. What would he have to bowl next time in order to have a mean score of 128?
Solution:
Let x represent Aaron's fourth and unknown score. To have a mean of 128, the sum of the four scores would have to be divided by 4. To get that sum by itself, multiply it by 4. You also have to multiply the desired mean of 128 by 4. So the sum of the four scores is equal to 128 times 4.
121 + 147 + 96 + x = 128 ∙ 4
• Substitute in the values of the four scores.
364 + x = 512
• Simplify.
364 - 364 + x = 512 - 364
• Subtract 364 from each side of the equation.
x = 148
• Simplify.
Aaron must score a 148 in order to have a mean score of 128.

Step-by-step explanation:
A parallelogram is just a tilted rectangle, so it uses the same formula, base times height.
This would be 8.7 × 16.9
87 × 169 = 14703
move the decimal to get
8.7 × 16.9 = 147.03

Answer: -4 1/3, -1/6, 5/6, 4 1/3
Step-by-step explanation:
To the left of the number line we would have the negatives which are -4 1/3, and -1/6. Then, to the right we have 5/6 and 4 1/3 because they are positives. That's the order they would go in from left to right on the number line.
Answer:
In order of least to greatest:
-2 1/2, -3/8, 7/8, 2 1/2
Step-by-step explanation:
First, we look at the negatives. Which one is the bigger number -2 1/2 or -3/8?
-3/8 is the bigger number, making the negative order on the left -2 1/2, -3/8.
Now we look at the positives. Which one is bigger, 7/8 or 2 1/2? 2 1/2 is the bigger number. Meaning the right side of the number line should look like 7/8, 2 1/2.
All together we get -2 1/2, -3/8, 7/8, 2 1/2

Answer:
13
Step-by-step explanation:
To solve the problem, you have to do A squared + B squared = C squared. So for your A and B it doesn't matter what order you put them in. We will do 12 sqaured + 5 squared = C squared. 12 squared is 144 and 5 squared is 25. By adding 144 and 25 together, it gives us 169. When we take the square root of 169, we get 13. 13 is the length of the hypotenuse.
A. 34

A rectangle has perimeter 20 m . Express the area of the rectangle as a function of the length of ones its side.
Answer:
A = 10W - W²
Step-by-step explanation:
Perimeter of a rectangle = 2(L+W)
Area of a rectangle =LW
L is the length
W is the width
Given
Perimeter = 20m
20 = 2 (L+W)
10 = L+W
L = 10 - W ....2
Substitute equation 2 into the formula for calculating the area
Recall that A = LW
A = (10-W)W
A = 10W - W²
Hence the area of the rectangle as a function of the length of ones its side is expressed as A = 10W - W²

How can-9 4/5
be expressed as the sum of its integer and fractional parts?
The fraction -9 4/5 can be expressed as the sum of its integer and fractional parts, which is -9 + 4/5
Expressing How can-9 4/5 as the sum of its integer and fractional partsThe integer part of a mixed number is the whole number portion, while the fractional part is the remaining fraction.
In this case, the integer part of -9 4/5 is -9, and the fractional part is 4/5.
To express the mixed number as the sum of its integer and fractional parts, we simply add the integer and the fraction:
So, we have
-9 + 4/5
When evaluated, we get
-9 + 4/5 = -45/5 + 4/5 = -41/5
Therefore, -9 4/5 can be expressed as the sum of its integer and fractional parts, which is -9 + 4/5 = -41/5.
