The average weight for three children was 79.6 pounds. What was the sum of their
weight?
Answer: 238.8
Step-by-step explanation:
To get an average, you add the weights together, the sum. And then you divide by how many children there was.
To go backwards, you'd times the average by the amount of children there were, 3, to get the sum
79.6 times 3 is 238.8
A gaming
console costs
$300 and has
8% tax. How
much is the tax?
$30 or $24?
Answer:
24
Step-by-step explanation:
8 percent of 300 is 24.
that should be right
Answer:
$24
Step-by-step explanation:
The tax is how much more you have to pay based on a percentage of the initial cost. The tax percent in this case is 8%. Since the console costs $300, we take 8% of $300 and charge it as the tax.
$300 * 8% = $300 * 0.08 = $24
If done by hand, move the decimal place on 0.08 to the left 2 times
0.08
00.8
008
This will give you 8. Multiply 8 by $300 which will give you $2400, next move the decimal to the right 2 times.
$2400.
$240.0
$24.00
Now you have $24

write 1.87 as a fraction.
Answer:
[tex]1\frac{87}{100}[/tex]
Step-by-step explanation:
A decimal is another way of representing a fraction such that the denominator of the fraction is a power of (10).
In the number (1.87), the number goes two places behind the decimal point, which means that the denominator of the fraction is (100), and the numerator is the given number excluding the decimal point.
[tex]\frac{187}{100}[/tex]
Simplify, write as a mixed number,
[tex]1\frac{87}{100}[/tex]
help with this please!,
Answer:
-6
Step-by-step explanation:
g(-4) here x = -4
So, we have to take g(x) = x - 2
g(-4) = -4 -2 = - 6
g(1) , here x = 1 ,
So, we have to take g(a)= -x +1
g(-1) = -1 + 1 = 0
g(-4) + g(-1) = -6 +0 = -6

Marcy needs 150 feet of fabric for her project. She uses 20% of it. How many feet of fabric did she use for her project so far? You may use a bar model or double number line.
Answer:
The answer is 120 feet of fabric
Answer:
30 feet.
Step-by-step explanation:
Steps
First, convert the percentage discount to a decimal. 20 percent of 150 is 0.20 in decimal format.
Secondly, multiply the decimal discount by the price of the item to determine the savings in dollars.
In this case, the original fabric needed equals 150 feet, you would multiply 0.2 by 150 to get the answer.
Solution
20 percent *150 =
(20:100)*150 =
(20*150):100 =
3000:100 = 30
Therefore, she used 30 feet for her project so far.
HELPPPPPP ME PLSSSSSSSSSSSSSSSSSSSSSSSS
Answer:
D. b and c
Step-by-step explanation:
Find the roots: x^2−12x+32=0.
Enter your answers in the boxes (numbers only).
The answers are 4 and 8.
Because:
x^2 - 12x + 32 =
(x - 4)(x - 8)
x - 4 = 0
+4 +4
x = 4
x - 8 = 0
+8 +8
x = 8
Cups by the water cooler are in the shape of a cone. The height is 15 cm and the diameter is 7.6 cm.
What is the volume of one water cooler cup, in cubic centimeters? (Use 3.14 for
π.)
Answer:
226.7 cm³
Step-by-step explanation:
The cone volume formula is V = (1/3)(base area)(height).
Here that comes out to V = (1/3)(pi)(3.8 cm)^2·15 cm, or 226.7 cm³

The length of a picture frame is 6 inches more than the width. For what values of x is the perimeter of the picture frame greater than 152 inches?
Answer:
35
Step-by-step explanation:
35 is exactly 152 but since its asking for greater then you're right it is 36.
But since it says '>' it means not equal to so it would be:
x > 35
or
x ≥ 36

W
V
7x + 5
mZWVT =
Answer:
40
Step-by-step explanation:
[tex] \frac{35x - 2 - 93}{2} = 7x + 5[/tex]
[tex] \frac{35x - 95}{2 } = 7x + 5[/tex]
[tex]17.5x - 47.5 = 7x + 5[/tex]
[tex]17.5x = 7x + 52.5[/tex]
[tex]10.5x = 52.5[/tex]
[tex]x = 5[/tex]
Plug 5 in for 7x+5.
[tex]7(5) + 5 = 40[/tex]

Solve the equation using the distributive property and properties of equality. 2 (x minus 8) = 68 What is the value of x?
Answer:
x=42
Step-by-step explanation:
2(x-8)=68
Distribute the 2
2x-16=68
Use the addition property of equality (add 16 to both sides)
2x=68+16
2x=84
Use the division property of equality (divide both sides by 2)
x=84/2
x=42

Rewrite without absolute value for the given conditions:
y =|x −3|+|x +2|−|x −5|, if x < −2
Answer:
y = -x - 4
Step-by-step explanation:
y =|x −3|+|x +2|−|x −5|, if x < −2
let x = -1
y1 =|x −3|
y1 = - ( x - 3 ) = -x + 3
y2 = |x +2|
y2 = - (x +2) = -x - 2
y3 = |x −5|
y3 = - (x −5) = -x + 5
y = y1 + y2 + y3
substitute back into original
y = -x + 3 - x - 2 - (-x + 5)
y = -x + 3 - x - 2 + x - 5
y = -x - 4
