What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
Olivia has read 40 pages of a 70-page book.
We need to find percent of pages has Olivia read
Let x be the percent of books olivia read.
This can be done by 70 x=40

m<GFD = 50°
m<CFD = 40°
Segment FD doesn't bisect <CFG because the angles aren't equal.
Step-by-step explanation:
<CFD and <GFD are complementary angles and their sum is 90°
-5x + 5 -7x + 1 = 90° add like terms
-12x + 6 = 90
-12x = 84 divide both sides by -12
x = -7
m<CFD is -5x + 5 ➡ (-5)×(-7) + 5 = 40°
m<GFD is -7x + 1 ➡ (-7)×(-7) + 1 = 50°

Answer:
y = 7
Step-by-step explanation:
The equation of the line is y = 7 because since it's a horizontal line the y value will always stay the same, and the x value will always be changing. Therefore you could draw a line straight across the y-axis at 7
Reduce the fraction to the lowest term
[tex] \frac{4}{8} [/tex]
Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
To reduce the fraction to the lowest term, we divide the like term by the GCF of its numerator and denominator.
Here,
As 4 and 8 have the GCF as 4 itself. We divide both the numerator and denominator with the GCF (4).
Hence,
[tex]\frac{4}{8}\\=\frac{4}{8}/\frac{4}{4} \\=\frac{4/4}{8/4} \\=\frac{1}{2}[/tex]

31.7. 3
31.8. 3
31.83. 6
31.9. 15

Step-by-step explanation:
A professor grades students on four tests, a term paper, and a final examination. Each test counts as 15% of the course grade. The term paper counts as 20% of the course grade. The final examination counts as 20% of the course grade. Alan has test scores of
92, 78, 82, and 90.
Alan received an 80 on his term paper. His final examination score was 86. Use the weighted mean formula to find Alan's average for the course. (Round your answer to one decimal place.)
Answer:
The Alans's average for the course is 84.5
Step-by-step explanation:
We are given
There are 4 tests, A Term paper and a Final examination.
Score = 92, 78, 82, 90.
Term paper score = 80
Final examination score = 86
Weighted mean = ∑ w.f/∑w
also the sum of all the weights is 100% = 1
weighted mean = 15%*92 + 15%*78+15%*82+15%*90+20%*80+20%*86/1
= 51.3 + 33.2
= 84.5
Therefore the Alans's average for the course is 84.5
Order these numbers from least to greatest.

Tell whether the x- and y-values in the table show a proportional or non-proportional relationship. If the relationship is proportional, tell the rule. Select one:
aProportional; x = 3/7y
bNon-proportional
cProportional; x=1/3y
dProportional; x=2/5y
Answer:
b. Non-proportional
Step-by-step explanation:
A table of values that represents a proportional relationship will have the same ratio of every pair in the given table. That is, y/x will result in the same value all through for every given pair.
The table of values given does not show a proportional relationship, because the ratio of y to x of each given pair of values are different and unequal:
y/x = 3/1 ≠ 5/2 ≠ 7/3 ≠ 9/4
Therefore, it is non-proportional.

Jean-Claude equally shared a box of chocolates with two of his friends. The box weighed 9/5 pounds. How many pounds of chocolate did each person receive?
I find that if you transform fractions into decimals, they become marginally easier to work with. Nine over five in decimal form is one point eight. If we divide 1.8 by three (Jean-Claude and his two friends), then we come up with the answer 0.6, which, once turned back into a fraction, would be six over ten, or three over five.

9514 1404 393
Answer:
y = -1/5x -1
Step-by-step explanation:
When given 2 points, it can work well to start with the 2-point form of the equation for a line.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (0 -(-2))/(-5 -5)(x -5) +(-2)
y = 2/(-10)(x -5) -2
y = -1/5x -1 . . . . . eliminate parentheses and collect terms
