Find the unit rate and answer the question. Only put the number of hours in as your answer. (Your answer will look something like this... 325)
rate :
distance/time225/375 miles/hr======================
1 hours → 75 miles
? hours → (1125/75)
15 hoursIt takes her 15 hours to drive 1125 miles.
Answer:
15 hours
Step-by-step explanation:
Finding how much distance in 1 hour
⇒ Ceci = 225 miles = 3 hours
⇒ 225 miles = 3 hours
⇒ 225/3 miles = 3/3 hours
⇒ (25 x 9)/3 miles = 1 hour
⇒ (25 x 3) miles = 1 hour
⇒ 75 miles = 1 hour
Finding how much hours in 1125 miles
⇒ 75 miles = 1 hour
⇒ 75x miles = 1125 miles = x hours
⇒ 75x/75 = 1125/75
⇒ x = 15
⇒ 75(15) miles = 1125 miles = (15) hours
⇒ 1125 miles = (15) hours
Dean and his friends went to Aqua World Water Park, where they floated down the Lazy River for 1 2 of an hour. This was 1 4 of the total time Dean and his friends spent at Aqua World. Use an equation to find the total amount of time Dean and his friends spent at the park. To write a fraction, use a slash ( / ) to separate the numerator and denominator.
What is the value of x?
Answer:
x = 10
Step-by-step explanation:
the two angles shown are supplementary, they add up to 180 degrees
so we can write this equation to solve for 'x':
100 + 9x - 10 = 180
90 + 9x = 180
9x = 90
x = 10
Answer:
[tex]\tt x=10^o[/tex]
Step-by-step explanation:
The given angles are supplementary angles, meaning they add up to 180°.
[tex]\tt 100+ 9x - 10 = 180^o[/tex]
[tex]\tt 90 + 9x = 180^o[/tex]
[tex]\tt 90+9x-90=180-90\:\: (Subtract)[/tex]
[tex]\tt 9x=90[/tex]
[tex]\tt \cfrac{9x}{9}=\cfrac{90}{9}\;\;(Divide)[/tex]
[tex]\tt x=10^o[/tex]

Answer:
a. the relationships between the area of walls left to paint and the time they have been working
b. Company 1
c. Company 2
d. Company 1 = 147 hours, company 2 = 162 hours
Step-by-step explanation:
a. The linear functions model the relationships between the area of walls left to paint and the time they have been working.
b. Company 1 is painting faster because the first line has a slope of -1000/7 while the second line has a slope of -100/9, which means Company 1 is painting 100 ft^2 every 7 hours while Company 2 is painting 100 ft^2 every 9 hours. Therefore Company 1 is going faster.
c. Company 2 had less area to paint when they began because at the 0 hour mark, company 1 had 2100 ft^2 to paint and company 2 had 1800 ft^2 to paint.
d. Company 1 will take 21*7=147 hours to finish. Company 2 will take 18*9=162 hours to finish.
I hope these solutions were helpful. Happy mathing!

Answer:
4) 2,400
5) The graph is going up by 500's and this could be misleading because you would have to estimate the elevation.
Step-by-step explanation:
Answer:
it depends
Step-by-step explanation:
for 4 you could say mountain a is 2,250 feet higher or that it is x% higher.
for 5 you could put "the graph may be misleading because the graph starts at a non-0 number thus making one mountain seem much taller than the other" because both mountains start at 16,500 and not 0 making the difference seem more extreme than it is.

Given the data presented in the bar graph, which age group represents 25% of the people at the family reunion? A) 10−19 B) 20−29 C) 30−39 D) 50−59
Answer:
B
Step-by-step explanation:
First you find the amount of people at the reunion which was 80. Then you find 25% of 80. 25% of 80 is 20. The only age group with 20 people is the 20-29 year olds.
Robert had some friends at his house after school. His mom cut up 2 pies for them to eat. If she cut each pie into fourths, how many pieces will there be? Choose the model that represents the answer.
1/4
8/8
2/8
4/4
NO LINKS!!!!!)
Answer:
8/8
Step-by-step explanation:
There are two pies, and each one was cut into fourths. There are four fourths in a whole, and since there are two wholes, there are two four fourths (I don't know if this makes sense).
Basically, multiply how many fourths (four per pie) by how many pies there are.
4 x 2 = 8
There are 8 pieces.

what is 2∙ 2∙ 2∙ 2∙ 2∙ 2∙ 2∙ 2∙ 2 in exponential form?
Only answer if you know 100% if you get it right I'll give brainliest
let's write 2*2*2*2*2*2*2*2*2 in exponential form.
Notice 2 has been multiplied times itself 9 times.
Basic exponential notation:-
[tex]\sf{2*2=2^2}[/tex]
[tex]\sf{2*2*2=2^3}[/tex]
[tex]\sf{2*2*2*2=2^4}[/tex]
You should notice a pattern.
This is the pattern:-
The number of times 2 has been multiplied times itself is the exponent.
In this case, we multiplied 2 times itself 9 times.
Hence, the answer is
[tex]\bigstar{\boxed{\pmb{2^9}}}[/tex]

Which of the following proportions could be used to convert 6 days to hours?
Answer:
[C] [tex]\frac{6\;days}{x\;Hours}=\frac{1\;day}{24\;Hours}[/tex]
Step-by-step explanation:
Since, we know that
1 Day = 24 Hours
6 Days = x Hours
Cross Multiply:
6 x 24 = 144
1x = 144
x = 144
144 = 144
Hence, the best answer is [C] [tex]\frac{6\;days}{x\;Hours}=\frac{1\;day}{24\;Hours}[/tex]
~lenvy~
The following proportions could be used to convert 6 days to hours as 1 day : 24 hours :: 6 days : x hours.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
There is a way to convert 6 days to hours, to use the proportion:
⇒ 1 day : 24 hours :: 6 days : x hours
This proportion shows the relationship between days and hours, and can be used to convert from one unit to the other. To solve for x, we can cross-multiply and divide:
x = 6 days × 24 hours / 1 day = 144 hours
So, 6 days is equivalent to 144 hours.
Hence, the correct answer would be an option (C).

Stevie is moving up to the attic and wants to paint a wall white. The wall is a triangle with a base of 20 feet and a height of 21 feet. What is the area of the wall?
Answer:
Step-by-step explanation:
Remark
Use the formula for the Area of a Triangle to find the number of square feet the paint will have to cover.
Formula
Area = 1/2 base * height
Givens
b = 20 feet
h = 21 feet
Solution
Area = 1/2 * 20 * 21
Area = 1/2 * 420
Area = 210 square feet

Answer:
Step-by-step explanation:
There are at least 2 ways you could do this. The best way is to use algebra. The trick is to equate 0.444444 to x, and then create a second equation by multiplying the first equation by 10. In doing this, you can subtract the two equations and that will get rid of the decimal.
10x = 4.444444...
x = .444444... Now subtract these 2 equation
9x = 4 Divide both sides by 9
9x/9 = 4/9
x = 4/9.
Since you are given choices, you could put each one into your calculator.
1/9 = 0,111111 not the answer.
40 /99 = 0.40404040 which is close but not the answer.
4 / 99 = 0.040404 ... which again is close but not the answer.

A bag contains tiles of different colors. Roshan randomly selects a tile from the bag and returns the tile to the bag after recording the color. He picks a green tile 6 times, a red tile 20 times, a blue tile 7 times, a purple tile 8 times, and a black tile 4 times. Based on the results, what is the theoretical probability that the next tile Roshan picks will be green?
Answer:
6/41
Step-by-step explanation:
6 + 7 + 20 + 8 = 41 so that is number of tiles he took. 6 of those were 41 so therefore, the chance is 6/41
Answer:
There are four red marbles and six blue marbles in all, for a total of ten marbles.
Without replacement, the probability of the first marble being blue is 6/10, while the probability of the second marble being red is 4/9.
The probability of both events occurring is reduced to 4/15 by multiplying 6/10 * 4/9 = 24/90.
