A boat can travel 105 miles on 15 gallons of gasoline. How much gasoline will it need to go 140 miles?
90 gallons
980 gallons
20 gallons
35 gallons
Answers
Answer:
20 gallons
Step-by-step explanation:
105/15=7
7*20=140
First you have to find the ratio or unit rate so 105/15= 140/x x is the gasoline needed so when you cross multiply you get 2100/105x divide both sides by x and you get 20

What is the absolute deviation of Victoria’s quiz score from the mean?
A. 0 points
B. 2 points
C. −1 point
D. 1 point
Please give the right answer
Answers
Answer:
B. 2 points(Approximately)
Step-by-step explanation:
The mean absolute deviation (MAD) is defined as
[tex]MAD=\frac{\Sigma |x_{i}-\mu| }{N}[/tex]
Where [tex]\mu[/tex] is the means and [tex]N[/tex] is the total number of elements.
First, we need to find the mean:
[tex]\mu = \frac{\Sigma x_{i} }{N} =\frac{18+12+15+10+13+20+16+12+18+6}{10}= \frac{140}{10}\\ \mu=14[/tex]
Then, we calculate the difference between each value and the mean, from that difference, we are gonna use the absolute value.
18 - 14 = |4|
12 - 14 = |-2|
15 - 14 = |-1|
10 - 14 = |-4|
13 - 14 = |-1|
20 - 14 = |6|
16 - 14 = |2|
12 - 14 = |-2|
18 - 14 = |4|
6 - 14 = |-8|
Now, we sum all terms and divide them by the total number of elements, which are 14.
[tex]MAD=\frac{4+2+1+4+1+6+2+2+4+8}{14}= \frac{34}{14}\\ MAD \approx 2.4[/tex]
Therefore, the absolute deviation is about 2 points. The right answer is B.

Answer: [tex]-2x^2 + 10x-8[/tex]
Step-by-step explanation:
To find the product of the binomials, we first need to find the linear equations for the lines.
Using the rise over run method for f(x), we can see that the line rises 2 units for every 1 unit ran. 2/1 = 2, so we know the slope is 2, and we can see that the y-intercept on the graph is -2.
Equation: [tex]f(x) = 2x-2[/tex]
Using the rise over run method for g(x), we can see that the line rises -1 unit for every 1 unit ran. -1/1 = -1, so we know the slope is -1, and we can see that the y-intercept on the graph is 4.
Equation: [tex]g(x) = -x+4[/tex]
Multiplying the binomials:
[tex](2x-2)(-x+4)[/tex]
Use the FOIL method:
First: 2x * -x
Outside: 2x * 4
Inside: -2 * -x
Last: -2 * + 4

answer is 28
2) 4x-7=49
add 7 to both sides
4x=49+7
4x=56
divide 56 by 4

answer is 12
Answer:
28 weeks
Step-by-step explanation:
It takes Mr. Holloway 8 weeks to make 2 guitars. Write this as a rate.
8 weeks
2 guitars
Divide the numerator and denominator by 2 to find the unit rate.
8 weeks÷2
2 guitars÷2
=
4 weeks
1 guitar
It takes Mr. Halloway 4 weeks to make 1 guitar. You want to find how long it will take him to make 7 guitars. Write a proportion.

A circle has a radius of 5 in. A central angle that measures 150° cuts off an arc.
Explain how to find the arc length exactly, and then approximate it to one decimal place.
Answers
Answer:
Part 1) The exact value of the arc length is \frac{25}{6}\pi \ in
Part 2) The approximate value of the arc length is 13.1\ in
Step-by-step explanation:
ind the circumference of the circle
The circumference of a circle is equal to
C=2\pi r
we have
r=5\ in
substitute
C=2\pi (5)
C=10\pi\ in
step 2
Find the exact value of the arc length by a central angle of 150 degrees
Remember that the circumference of a circle subtends a central angle of 360 degrees
by proportion
\frac{10\pi}{360} =\frac{x}{150}\\ \\x=10\pi *150/360\\ \\x=\frac{25}{6}\pi \ in
Find the approximate value of the arc length
To find the approximate value, assume
\pi =3.14
substitute
\frac{25}{6}(3.14)=13.1\ in
