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]

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°.

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.
hope this helps :)

Answer:
C. (5-1), (5-2), (5-3), (5-4), (5-5), (5-6)
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.

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 ping pong ball (0.02 kg), bowling ball (25 kg), cotton ball (0.3 kg), wrecking ball (500 kg), and baseball (5 kg) are all moving with the same velocity. Which answer choice lists them from least kinetic energy to most kinetic energy?
A
Wrecking ball, bowling ball, baseball, ping pong ball, cotton ball
B
Cotton ball, baseball, ping pong ball, bowling ball, wrecking ball
C
Cotton ball, pin pong ball, baseball, bowling ball, wrecking ball
D
Ping pong ball, cotton ball, baseball, bowling ball, wrecking ball
Answer:
D) Ping pong ball, cotton ball, baseball, bowling ball, wrecking ball.
Step-by-step explanation:
If they are moving at the same time, the objects that have more mass have more kinetic energy.
the heaviest is the wrecking ball, and then the bowling ball, the baseball, the cotton ball, and the ping pong ball.
The only answer that follows this (in reverse) is D

Step-by-step explanation:
which is the measure of ∠DBC?
Answer: 20°
Step-by-step explanation:
There is 180 degrees in the triangle. ∠C is 50°, ∠A is 80°, ∠B is 30°, and the total adds up to 160°, so 180-160 equals 20.
Answer: 20 degrees
Step-by-step explanation: if you add up the angles of any triangle, the sum should always be 180. so add up angle A and angle C :
80 + 50 = 130
subtract that from 180 to find out what angle ABC is:
180 - 130 = 50
since we know that angle ABD is 30 degrees, all we have to do now is subtract that from 50:
50 - 30 = 20
angle DBC = 20 degrees

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:

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]

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

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 map below, the path from the whales to the sharks is parallel to the path from the penguins to the fish tanks.
A map of the aquarium at the City Zoo. A triangle has points whales, sharks, dolphins. The distance from Whales to sharks is 54 feet and from whales to dolphins is 30 feet. A triangle with points Dolphins, fish tanks, penguins. The distance from dolphins to fish tanks is 45 feet, and from penguins to fish tanks is x feet.
What is the distance between the penguins and the fish tanks?
25 feet
36 feet
69 feet
81 feet
Answer:
(D) 81 feet
Step-by-step explanation:
From the figure drawn, it is given that AB is parallel to DE, in ΔABC and ΔCDE, we have
∠BAC=∠DEC(Alternate angles)
∠ACB=∠DCE(Vertically opposite angles)
Thus, by AA rule, ΔABC is similar to ΔCDE.
Since the line connecting from the whales to the sharks is parallel to the line connecting from the penguins to the fish tanks, the triangles shown in the figure are similar. Using the property of similar triangles.
