The graph shows gas mileage for a car. What is the unit rate?
A)

B)

27
09
27 miles per gallon
D)
54 miles per gallon
Answer:
The unit rate = 27 miles per gallon.
Hence, option C is true.
Step-by-step explanation:
From the given line graph:
Taking two points
(2, 54)(6, 162)The unit rate can be determined by finding the rate of change or slope between the points (2, 54) and (6, 162)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(2,\:54\right),\:\left(x_2,\:y_2\right)=\left(6,\:162\right)[/tex]
[tex]m=\frac{162-54}{6-2}[/tex]
Refine
[tex]m=27[/tex]
Therefore, the unit rate = 27 miles per gallon.
Hence, option C is true.
2. Write the slope-intercept form of the equation of the line described.
Parallel to y=-x-5; through (4, -3)
Answer:
y = -x + 1
Step-by-step explanation:
We're putting it into the form y=mx+b where m is the slope, and b is the y-intercept.
When two lines are parallel, they have the same slope, so the slope is going to be -1.
New equation: y = -x + b.
Now, you know that (4, -3) is a solution so you can plug in x = 4 and y = -3, then see what value of b make the equation true.
-3 = -4 + b
add 4 to both sides
1 = b
This means that the equation is y = -x + 1

The base of an isosceles triangle is seven less than twice one of the congruent sides. If the perimeter of the triangle is 63 cm, find the length of each side.
Answer:
17.5
Step-by-step explanation:
let 'x' = each congruent side
let '2x - 7' = side of base
x + 2x - 7 = 63
3x = 70
x = 17.5

If a wave has a wavelength of 20 meters and is
traveling at a rate of 60m/s, what is its
frequency?
Answer:
Frequency of wave = 3 Hertz
Step-by-step explanation:
Given that:
Wavelength of wave = 20 meters
Velocity of wave = 60m/s
We know that:
v = fλ
Here,
v = velocity , f = frequency and λ = wavelength
Putting values in formula
60 = f(20)
20f = 60
Dividing both sides by 20
[tex]\frac{20f}{20}=\frac{60}{20}[/tex]
f = 3 Hertz
Hence,
Frequency of wave = 3 Hertz
Write two multiplication equations that compare the number of blue fish 16 to the number of yellow fish 4
Answer:
b = 4y
y = 1/4 * b
Step-by-step explanation:
Number of Blue fish = 16
Number of yellow fish = 4
Let:
Blue fish = b
Yellow fish = y
b = 4y
b = 4(4)
b = 16
From ;
b =4y
y = b/4
y = 1/4 * b
Hence,
y = 1/4 * 16
y = 16/4
y = 4

An angle measures 58.6° less than the measure of its complementary angle. What is the
measure of each angle?
Answer:
Your answer is 31.4°.
Step-by-step explanation:
The answer itself just requires very simple thinking. Complementary angles are any two angles that add up to 90 degrees. We are given ANGLE<1, so all we have to do is subtract 90 from 58.6 to find ANGLE<2.
90°-58.6°= 31.4°

How do u convert decimals to percents and percents to decimals????????
Answer:
To convert a decimal to percent, just multiply it by 100, or move the decimal place 2 times
Ex: 0.29 x 100 = 29
The answer would be 29%
To convert a percent to a decimal, do the opposite
Ex: 29%/100 = 0.29
To convert decimals to percents is to multiply by 100 then add a percent sign. To convert percents to decimals is to move the decimal point two places to the left or divide by 100 and remove the percent sign.
Step-by-step explanation:
Example:2.5%
2.5% can be expressed in decimal form as 0.025. Since a percent represents the part per 100 to convert a percent to a decimal divide 2.5 by 100.
2.5/100=0.025.
Example:2.5
2.5 can be expressed in percent form as 250%.Since a decimal represents a fraction and a percent is out of 100, to convert a decimal to a precent multiply 2.5 by 100.
2.5 x 100=250
Add the percent sign
250%
TODAY ONLY: Towels are 30% off at the Towel Emporium. If our total before discount was $99.30, what is the price we will pay?
Answer:
$69.51
Step-by-step explanation:
To solve the discount problem we have to multiply the price by the new percent (trust me it will make sense later)
To find the new percent after the 30% discount we have to subtract 30% from 100% which will leave us with 70% or 0.70
Now we multiply:
$99.30 x 0.70 = 69.51
So the new price after the discount is $69.51

Jo walks to school every day. The probability Jo is late on a Monday is 0.4. The probability Jo is late on a Tuesday is 0.2. What is the probability that Jo is not late on Monday?
Answer: The probability that Jo is not late on Monday = 0.6
Step-by-step explanation:
The probability of getting late is independent on each day.
Also, for an event E
Probability of not E = 1- P(E) , where P(E) = Probability of happing E
Given: The probability Jo is late on a Monday is 0.4.
Then, the probability that Jo is not late on Monday = 1-0.4= 0.6
Hence, the probability that Jo is not late on Monday = 0.6

Answer:
-0.4
Step-by-step explanation:
its that one
The strongest correlation is -0.4.
Option C is correct.
What is correlation?Correlation is a statistical term that expresses how closely two variables are related linearly (meaning they change together at a constant rate). It's a typical tool for describing simple relationships without stating a cause and effect link.
When the result is closer to +1 (positive correlation) or -1 (negative correlation), the strongest correlation is considered (negative correlation).
A positive correlation coefficient means that the value of one variable is directly related to the value of another.
Here -0.4 is the closest value to 1.
So, the strongest correlation is -0.4.
