help me its math khan academy 8th grade math
Answer:
95%
Step-by-step explanation:
So, we can see on the chart that 78 out of 82 people from ages 18 to 22 use Face.book. So we're trying to find what percentage 78 is of 82:
The first step is to write 78 as a fraction of 82, which is:
78/82
In order to find the simplest form of 78/82 we cancel out the greatest common divisor of 78 and 82, which is 2 :
78/82 = 37/41
Now we just need to convert this fraction to a percentage :
37/41 = 95% (rounded)
So we have the final answer :
78 is 95% of 82
Which means that:
Approximately 95% of people from ages 18 to 22 use Face.book

Answer:
The exponential equation is y = -2×(1/2)^x
Step-by-step explanation:
1) The horizontal asymptote of the function is the x axis (always nice)
2) At x=0, y=-2 (i.e, this function will be multiplied by -2 bc the exponent part will transform into one at x=0)
3) Then we need to ascertain the base of the exponential. Based on the facts that at x=1, y=-1 and the "a-value" is -2, we can set up an equation to find b:

Fares has a container filled with 540 grams of tea leaves. Each morning, he uses 6 grams to make a cup of tea.
Write an expression to represent the grams of tea leaves remaining after x days.
How many grams of tea leaves will remain after 17 days? Show your work.
Answer:
Step-by-step explanation:
Quantity of tea leaves used for one morning = 6 grams
Quantity of tea leaves used for 'x' days = 6 *x = 6x grams
Quantity of tea leaves left after x days = 540 - 6x
Expression: 540 - 6x
Quantity of tea leaves remaining after 17 days = 540 - 6*17
= 540 - 102
= 438 grams

A juice factory offers its juice in both bottles and cans. A class of students on a field trip decides to compare the numbers of cases of bottled juice and canned juice that are packaged each minute. The students count the number of cases that are packaged on each assembly line over several minutes.
What is the unit rate for canned juice, in cases per minute? Explain how you found this unit rate.
Answer: 50 cases per minute
Step-by-step explanation:
1. Select one of the points on the graph. Let's use (2, 100) in this case.
2. Divide the number of cases (y) by the amount of minutes (x) This means the equation would be 100 ÷ 2.
3. Since 100 cases ÷ 2 minutes = 50 cases per minute, that means that is unit rate, which can be expressed by y = 50x or f(x) = 50x.
In the figure, line m is parallel to line n. The measure of angle 2 is 40 degrees and the measure of angle 3 is 68 degrees. What is the measure of angle 5?
Explain how you found the answer using the relationships of angles.
Answer:
∠1 - 40°
Step-by-step explanation:
∠1 - 40°
b/c it's a right triangle and we have two angles given, 50° and 90°. Add them and subtract by 180° and get 40°.
∠2 - 140°
b/c an exterior (outside) angle is equal to the two most isolated / farthest angles added. The two most is angles are 105° and 35°, add them and get 140°.
∠3 - 40°
b/c ∠'s 1 and 3 are vertical angles meaning they're equal so since ∠1 is 40°, so is ∠3.
∠4 -
b/c ∠' s 2 and 4 are vertical angles meaning they're equal so since ∠2 is 140°, so is ∠4.
∠5 - 35°
b/c we have two angles, 105° and 40°. Add them and subtract by 180° and get 35°.

Find the area of the semicircle. Round your answer to the nearest hundredth.
Answer:
56.52
Step-by-step explanation:
This is because in order to find an area of a circle you must do R^2*3.14 and since it is a semicircle add /2 so R^2*3.14/2 and since half of 12 is 6, 6*6 is 36 and 36*3.14 is 113.04 and divide that by 2 which is 56.52
Answer:
177.475 [tex]inches^{2}[/tex]
Step-by-step explanation:
Since the formula for finding the area of a full circle is A = π[tex]r^{2}[/tex], area equals pi times radius squared, we fill out the formula and solve.
A: unknown
Pi: 3.14
Radius: diameter is 12, so you divide it by 2, which is 6.
A = 3.14 x 6 squared.
using pemdas, you do exponents first,
A = 3.14 x 36
A ≈ 113.04
Now that we have the area for the full circle, we divide it by two to find the area of the semicircle,
113.04/2
= 56.52
So, the area of the semicircle is 56.52 [tex]inches^{2}[/tex]

Step-by-step explanation:
So let's look at the choices and find which one has only one 3 (3's will be boldened for convenience).
A. (1-1), (2-2), (3-3), (4-4), (5-5), (6-6)
A has two three's, so it's out.
B. (1-3), (2-3), (3-1), (3-2), (3-4), (3-5), (3-6), (4-3), (5-3), (6-3)
B has 10 three's, so it's also out.
C. (5-1) (5-2) (5-3) (5-4) (5-5) (5-6)
C has 1 three, so it's correct. However I will still test D to make sure.
D. (1-6) (2-5) (3-4) (4-3) (5-2) (6-1)
D, like A, has two three's, so it's out.
With that information, we can deduce that C has the favorable outcomes for rolling exactly 1 three.

You spin the spinner, flip a coin, then spin the spinner again. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest tenth.
The probability of spinning an odd number, not flipping heads, then not spinning a 6 is
__
Using it's concept, it is found that the probability of spinning an odd number, not flipping heads, then not spinning a 6 is:
[tex]p = \frac{20}{81} = 24.69\%[/tex]
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
There are 5 odd numbers in the spinner, out of 9, hence the probability of spinner an odd number is 5/9.The coin is fair, hence the probability of flipping tails = not heads is of 1/2.Out of the 9 numbers in the spinner, only one is six, hence the probability of not spinning a 6 is of 8/9.Then, the probability of the compound event is:
[tex]p = \frac{5}{9} \times \frac{1}{2} \times \frac{8}{9} = \frac{20}{81} = 24.69\%[/tex]

What is the surface area of the triangular prism shown?
Answer:
Step-by-step explanation:
we need to find the surface area of the shapes before adding them together. the triangles are 6*4 and since there are two, we do not need to divide by 2. (normally to find the area of a triangle it is base times height divided by 2)
so the area of the triangles are 24 units. Next we have the outer rectangles. 7*5=35. Since there are 2, we multiply by 2. Last we have the middle rectangle. 7*6=42.
the whole equation would be: 24+70+42= 136
so your answer would be B: 136.

The distance travelled by Samantha from her friend's home to school will be 24 KM
What is pythagoraean theorem?The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the square of the other two sides.
Here Samantha is travelling in a right-angled triangular path so the distance between Samantha's school and her friend's home will be calculated as:-
H² = P²+B²
(30)² = x²+(18)²
x²= 900-324=576
x=√576
x=24 KM
Hence the distance travelled by Samantha from her friend's home to school will be 24 KM
