Answer:
28%
Step-by-step explanation:
18/25=.72 ->72% passed the test, so then we take 100 and subtract 72 from it which leaves us with 28% that did not pass the test
Answer:
28% of students did not pass.
Step-by-step explanation:
18/25 = 72/100
72% passed.
So, if 18/25 students passed, (72%) then 7/25 students did not pass (28%)

A shelf at a bookstore displays 30 books. Of these 30 books, 10 of the books are nonfiction books. The store owner adds 4 new fiction books to the shelf and wants the ratio of fiction books to nonfiction books to remain the same. What is the total number of nonfiction books that the store should display, after the new fiction books are added?
Answer:
2 he needs to add 2 to keep the ratio the same, the total would be 12
Step-by-step explanation:
before he adds the book the ratio is 2:1 (fiction to non-fiction) and he add 4 to the fiction so he needs to add 2 non-fiction books because this ration means fiction/2 = non-fiction so 4/2 = 2
hope this helps have a blessed day :)

3-2 = 1
4^3 = 64
64+1 = 65
Hope this helps.
Answer:
[tex]65[/tex]
Step-by-step explanation:
Firstly, you have to Simplify what's inside the parentheses.
and that is 3-2 = 1.
[tex] {4}^{3} + 1[/tex]
Secondly, you have to Simplify 4³ to 64. 4 to the power of 3 is 64.
[tex]64 + 1[/tex]
And lastly, you have to simplify 64 + 1. which is.
[tex]65[/tex]
Therefor, the answer is, 65.

two turkey burgers and a bottle of water cost $3.25. If three turkey burgers and a bottle of water cost $4.50,What is the cost of tw bottles of water?
Answer:
$1.50
Step-by-step explanation:
let b be the number of turkey burgers and w be the number of bottles of water.
[tex]2b + w = 3.25\\3b + w = 4.50[/tex]
becomes
[tex]3b + w = 4.50\\- (2b + w)=3.25[/tex]
[tex]b = 1.25[/tex]
substitute this into one of the original equations:
[tex]3b + w = 4.5\\3 * 1.25 + w = 4.5\\3.75 + w = 4.5\\w = 0.75[/tex]
two bottles of water equals 0.75 * 2 = 1.50
Find the other endpoint of the line segment with the given endpoint and midpoint.
Endpoint: (-9,7), midpoint: (10, -3)
Answer:
endpoint is (29, -13)
Step-by-step explanation:
Formula for midpoint is [tex](\frac{x_{1} + x_{2} }{2} ,\frac{y_{1} + y_{2} }{2} )[/tex]
So, let [tex](x_{2} , y_{2} )[/tex] be the coordinates of the endpoint you are looking for.
[tex]x_{1} = -9[/tex] and [tex]y_{1} = 7[/tex]
[tex](\frac{-9 + x_{2} }{2} , \frac{7 + y_{2} }{2} )[/tex] = (10, -3)
[tex]\frac{-9 + x_{2} }{2} = 10[/tex] [tex]\frac{7 + y_{2} }{2} = -3[/tex]
-9 + [tex]x_{2}[/tex] = 20 7 + [tex]y_{2} = -6[/tex]
[tex]x_{2} = 29[/tex] [tex]y_{2} = -13[/tex]
endpoint is (29, -13)
Jose is saving money for a skateboard. His aunt gives him $45 to start with, and he saves $3 each week. The expression 45 + 3w gives the amount of money Jose saved after w weeks. Osvaldo Matthew Part A) How much money will Jose have saved after 4 weeks? Part B) After 20 weeks, can Jose buy the skateboard? Explain why he can or why he cannot. 2.)Evaluate if k=8 and v=5. 6(5v - k)/2
Answer:
After 4 weeks, he will have $57
After 20 weeks, he will have $105
Step-by-step explanation:
6(5v - k) / 2
6(5(5) - 8) / 2
6(17) / 2
102/2 = 51
Answer: below
Step-by-step explanation:
Part A) After 4 week he will have saved ... (45+3x4= $57)... 57 dollars
Part B) After 20 weeks... (45+3x20= 105)... i dont know if he can buy the skate board bc you never said how much the skateboard cost.
2. 6(5v-k)/ 2
6(25-8)/2
150-48/2
102/2 = 51
(-a - b)x = 3a +3b.
Given:
The equation is
[tex](-a-b)x=3a+3b[/tex]
To find:
The value of x.
Solution:
We have,
[tex](-a-b)x=3a+3b[/tex]
It can be written as
[tex]x=\dfrac{3a+3b}{(-a-b)}[/tex]
[tex]x=\dfrac{3(a+b)}{-(a+b)}[/tex]
Cancel out the common factors.
[tex]x=\dfrac{3}{-1}[/tex]
[tex]x=-3[/tex]
Therefore, the value of x is -3.

Answer:
1. g. $0.10 per square inch
2. b. $0.08 per square inch
3. f. $10
4. m. $8
5. h. 79 in²
6. j. 113 in²
Step-by-step explanation:
1. A = πr²
r = diameter ÷ 2 = 10 ÷ 2 = 5
A = π(5)² = 25π in² ≈ 78.53981
$8.00/25π = $0.10 per square inch
2. A = πr²
r = diameter ÷ 2 = 12 ÷ 2 = 6
A = π(6)² = 36π in² ≈ 113.0973355
$10.00/36π = 0.088419 = $0.09 per square inch
3. information/answer was provided
4. information/answer was provided
5. A = πr²
r = diameter ÷ 2 = 10 ÷ 2 = 5
A = π(5)² = 25π in² ≈ 79 in²
6. A = πr²
r = diameter ÷ 2 = 12 ÷ 2 = 6
A = π(6)² = 36π in² ≈ 113 in²

Ethan reads 330 pages in 3/4 hour. How many pages does he read per hour?
Answer:
440
Step-by-step explanation:
330 divided by 3 times 4 is 440 and thats your answer.
====================================================
Work Shown:
330 pages = 3/4 hour
4*(330 pages) = 4*(3/4 hour) ........ multiply both sides by 4
1320 pages = 3 hours
1320/3 pages = 3/3 hours ...... divide both sides by 3
440 pages = 1 hour
Ethan's rate is 440 pages per hour.

what is the equation
example:: y=3/1x-6
Answer:
y = 4/6x - 4
Step-by-step explanation:
y = mx + b, m = slope and b = y intercept
Rise over run
Rise = +4
Run = +6
This means the slope is 4/6.
The y intercept is at -4.
Now, plug in the numbers for y = mx + b
y = 4/6x - 4

Answer:
the answer is 0.0800320128 or in simplified form 0.08
Step-by-step explanation:
First you divide 12 ÷ 5.88 = 2.04081632653. Then you divide 20 ÷ 10.20 = 1.96078431373. Lastly you subtract 2.04081632653 - 1.96078431373 = 0.0800320128 or 0.08
