A concrete slab has a length of 25 in, a height of 30 in, and a width of 20 in. There are 200 slabs needed for a job. What is the volume of all 200 slabs?
15,000 in3
250,000 in3
1,000,000 in3
3,000,000 in3
Answer:
3,000,000 in3
Step-by-step explanation:
The volume of each slab is 25x20=500. 500x30=15,000. per slab is an increased volume of 15,000.
Stacking 15,000 over 15,000 over and over again results in the volume of 200 be equal to 200(15,000). Take power away from the numbers and you have 2x15x100,000. Its equal to 3,000,000. Thats your answer

Answer:
11 is 405, 12 is 107.5, 13 im not sure of
Step-by-step explanation:
First on 11 you can just do 21*21 (the big square) and subtract that by 36 (which is 6*6, the small square), you'll get 107.5.
Then on 12, it is made up of a large rectangle, a small triangle, and a flatter triangle. The top triangle's formula is 1/2(7*3) which = 10.5. The big rectangle is 13*7 = 91. The last triangle is 1/2(4*3) which = 6. It is 3 because 13-10. Add all those up and you should get 107.5.
And I just want to know on number 13 if that 11 is the radius or diameter. I can't seem to tell.

A coin toss is used to simulate an experiment. Which of the following must be true about that experiment?
It must have four possible outcomes, each with a probability of 1/4 .
It must have four possible outcomes, each with a probability of 1/2 .
It must have two possible outcomes, each with a probability of 1/2 .
It must have two possible outcomes, each with a probability of 1/4 .
It must have two possible outcomes, each with a probability of 1/2 .
The correct option is (3).
What is Probability?A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1.
As per the given data:
A coin toss is used to simulate an experiment.
For finding probability of any event, we should know the sample space of the event.
The sample space for a coin toss can be obtained by observing all the possible outcomes when a coin is tossed.
Sample space = {H, T}
Where H is heads and T is tails.
There can be 2 possible outcomes, either the coin toss will result in a head or it will result in a tail.
P(H) = 1/2
Similarly
P(T) = 1/2
Hence, It must have two possible outcomes, each with a probability of 1/2 .

A quarter has a diameter of approximately 24 millimeters. What is the approximate area of the quarter ?
Answer choices:
75.36 mm square
452.16 mm square
150.72 mm square
1,808.64 mm square
Answer: 452.16
Step-by-step explanation: The formula for area is A=πr². The radius is half of the diameter, which would give us 12. so just plug in. 12² is 144. 144π is 452.38. (Which is close to 452.16) Hope this helps :)

Answer:
Step-by-step explanation:
we have to find if the series have a constant of proportionality by dividing the value of y by each value of x
1)
100 : 2 = 50
200 : 4 = 50
300 : 6 = 50
400 : 8 = 50
ok = y
2)
0.60 : 4 = 0.15
1.20 : 8 = 0.15
1.44 : 12 = 0.12
no = n
3)
0.15 : 1 = 0.15
0.3 : 2 = 0.15
0.45 : 3 = 0.15
0.6 : 4 = 0.15
ok = y

Four runners completed in a 10-kilometer relay race. Each Runner ran the same distance. What was that distance?
Answer:
each runner ran 2.5 kilometers
Step-by-step explanation:
10÷4=2.5
The distance would be 2.5 kilometers if four runners completed a 10-kilometer relay race while covering the same distance each.
What is division?A method of dividing something into equal parts is called division. It produces a fair distribution of resources and is one of the four basic operations in mathematics.
How to solve this problem?Total distance = 10 kilometers
Total number of runners = 4
Since they all covered the same distance,
the distance = 10/4 = 2.5 kilometers
Therefore, the distance would be 2.5 kilometers if four runners completed a 10-kilometer relay race while covering the same distance each.

What is the measure of ∠ZXY?
Answer:
55
Step-by-step explanation:
These angles are called complementary angles where the sum of the angles = 90°
So,
(4x + 7) + 35 = 90°
Subtract 35 on both sides
4x + 7 = 55
Subtract 7 on both sides
4x = 48
Divide 4 on both sides
x = 12
(Edit: 4(12) + 7 = 55, my bad I didn’t read the problem correctly and focused on solving for x)
Answer: ZYX=55 x=12
Step-by-step explanation: that square in the corner means the angle is 90 degrees so 90-35=55. XYZ=55 (now im guessing that wasn’t the whole question since there was an x) so then 55-7 (since you would do adding last, backwards you do subtraction first) =48. 48 divided by 4=12 x=12
