Find the unit rate. 108 people 12 days people : days = (Type whole numbers or decimals.)
108 people 12 days
the people:days=108:12
BUT this is not simplified of course
We simplify ratios like a fraction.
We can see that both numbers are divisible by 12
So we can do
108÷12/12÷12=9/1 (answer)
To know that both are divisible by 12 isn't hard as long as you are observant and are good with numbers and the divisibility rules of 2 and 3.

HELP PLEASE FAST 15 and 16 how to solve PLEASE
Answer:
15. 6
16. 40
Step-by-step explanation:
Use the formula for pythagorus: c^2 = a^2 + b^2
15. 10^2 = 8^2 + b^2
100 = 64 + b^2
*minus 64 on both sides
36 = b^2
*square root both sides
b = √36 = 6
16. c^2 = 24^2 + 32^2
c^2 = 576 + 1024
c^2 = 1600
*square root both sides
c = √1600 = 40
Hope this helps :)
1) 164
2) 1600
because a^2 + b^2 = c^2 <3

Find the Central arc measure
Answer:
The central arc measure is 125.
12. Two trains, Train A and Train B, weigh a total of 312 tons. Train A is heavier than Train B. The difference in their weights is 170 tons. Use elimination to solve the system of equations to find the weight of each train. a + b = 312 a-b= 170 a + b = 312 a - b = 170
Answer:
a = 241
b = 71
Step-by-step explanation:
a + b = 312 (#1)
a - b = 170 (#2)
(#1) + (#2) = 2a = 482.
a = 482 / 2 = 241.
b = 312 - 241 = 71.
Figure ABCD is a square. Find the
measure of ZABE.
B
С
A А
D
mZABE = [?]°
Answer:
∠ABE = 45°
Step-by-step explanation:
Since we know that the figure is a square, we know that ∠A, ∠B, ∠C, and ∠D are all 90°.
Assuming that Point E is at the center of the square, the lines will bisect each of the angles above. Half of 90° would be 45°.
∠ABE = 45°.
A college basketball player makes 70% of his free throws. At the end of a game, his team is losing by two points. He is fouled attempting a three-point shot and is awarded three free throws. Assuming each free throw is independent, what is the probability that he makes at least two of the free throws?
a. 0.784
b. 0.700
c. 0.216
d. 0.441
Answer:
B.
Step-by-step explanation:
If he makes 70% then 70% as a decimal would be 0.700 which is B
Probability is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
The probability that he makes at least two of the free throws is 0.0700.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head when a coin is tossed is 1/2
We have,
Each free throw is independent of the other.
Percentage of making free throws = 70%
The probability that he makes at least two of the free throws.
= 70%
= 70/100
= 0.07
This can be written as 0.0700.
Thus,
The probability that he makes at least two of the free throws is 0.0700.
