Step-by-step explanation:
To obtain score of 80% on entire exam means the student have to answer
(80/100)×80 = 64 correct answers
Student have already answered 75% of the first 60 questions correctly meaning
(75/100)×60=45 correct answers from first 60 questions
Remaining correct answers s/he have to answer
64-45=19
So from remaining 20 questions s/he have to answer 19 correct questions that is
20 × (x/100) = 19
x = 19 ×(100/20)
x = 95%

10 Points And Brainliest IF Correct
Answer:
1. 12 x 6 = 72 area of parallelogram: B x H (BH)
2. 15 + 23 = 38 x 10 = 380 divided by 2 = 190 area of trapezoid: (B1 + B2) x Height x 1/2 (basically dividing by 2)
3. 8 - 2 = 6 (b1) for the trapezoid, 6 (b1) + 8 (b2) = 14 x 4 (height) = 56 divided by 2 (multiplying 1/2) = 28. (Area of the triangle in the figure) 4 x 4 = 16 divided by 2 = 8. 28 + 8 = 36
Using the formula of a triangle: BH x 1/2 (basically dividing by 2)
pls answer im failing math and need an A
Answer:
4. 23
4. 206
5. 75 ft
7. 6 sections
8. 6 families
Step-by-step explanation:
4. 3x + 5 is the same thing as 3 x 6 + 5 so it equals to 23
4. x to the power of 3 - 10 is equal to 6 to the power of 3 - 10 so it equals to 206
5. Formula for area of triangle = 1/2 x base x height
So, it's 1/2 x 10 x 15 = 75
7. 3/4 ÷ 1/8 = 6 (Trick: When dividing fractions, make sure to flip the fraction for the 2nd one and leave the 1st one as the same. After that, multiply them together)
8. 3 families have 4-5 pets, 2 families have 6-7 pets and 1 family have 8-9 pets. At least 4 pets means 4 pets and above. So 3 + 2 + 1 = 6 families.
4. 3x + 5. Substitute the X for 6. The expression is (3 x 6) + 5= 23.
X³ - 10. Substitute the X for 6. 6³-10= 216.
5. I'm not 100% sure but I believe that it is 75. I might be wrong.
6. 6
7. 6

What is Proportion?Proportions are defined as the concept where two or more ratios are set to be equal to each other.
Suppose we have two ratio p : q and r : s.
If both these ratios are proportional, then we can write it as p : q = r : s or p/q = r/s
Given that,
Amount of food fed to Great Dane by Deon in 1 week = 62 cups
He has a new bag with 160 cups of dog food.
He needs this food to last up to 2 1/2 or 2.5 weeks.
We have,
Amount of food needed in 1 week = 62 cups
Let Amount of food needed in 2.5 weeks = x cups
Ratio of 1 week to 62 cups and 2.5 weeks to x cups will be equal.
So using proportional concept, we can write this as,
1 / 62 = 2.5 / x
We have to find the value of x.
Doing the cross multiplication,
x = 2.5 × 62 = 155 cups
So the amount of food needed in 2.5 weeks = 155 cups.
But he has a new bag with 160 cups which is more than enough for 2.5 weeks, since only 155 cups is needed for 2.5 weeks.
Hence the new bag of food will last until 2 1/2 weeks.

x+47=90
x=43
----------------
y+x=90
put in 43 for x
y+43=90
y=47
Hope that helps :)
Answer:
X=43
y=47
Step-by-step explanation:
Well you have 47 degrees. Finding X first would be easier.
X and 47 are complementary (90 degreees) so you can subtract 47 from 90 and get “x” Which is 43.
Now for y.
Y and X is complementary also, which means since x is 43, 90-43 is 47. So y is 47.
