What are the angle measures
Answer:
equation: 3x - 20 = 0
Step-by-step explanation:
3x = 20
add its opposite to both sides.
3x - 20 = 20 - 20
= 3x - 20 = 0

Find ƒ–1 for the function ƒ(x) = –2x + 1.
Answer:
Step-by-step explanation:
y = -2x+1
rearrange to solve for x
2x = -y+1
x = -½y + ½
f⁻¹(x) = -½x + ½ = -(x-1)/2
What is an equation of the line that passes through the point
(−1,−3) and is parallel to the line 4x-y=2?
Answer: y = 4x + 11
Step-by-step explanation:First, you put the equation into the standard “slope/intercept” form.
4x -y = 2 subtract 4x from both sides ; -y = -4x + 2 Multiply by -1 :
y = 4x - 2
In this standard form we see that the slope of the line (coefficient of x) is 4. ANY line parallel to this one must thus also have a slope of 4.
y = 4x - a (generic)
ANY other combination of slope multiples and constant terms will therefore also be lines parallel to this one. The one that passes through a specific point will simply have a different constant term.
We find this by putting our point value into the equation:
3 = 4(-2) + a ; 3 = -8 + a ; a = 11
Thus, our “parallel line equation” through the point (-2,3) is:
y = 4x + 11

Which value for x makes the sentence true? 1/10 + x = 1/7
Answer:
3/70
Step-by-step explanation:
change 1/10 and 1/7 so the denominator (bottom number) is the same. 1/10= 7/70 and 1/7= 10/70 so you need 3/70 to make the two numbers equal.

Answer:
area is 15 square units
16 units for perimeter
Step-by-step explanation:
perimeter refers to the sum of all of the sides
if the width of this rectangle is 3 squres, and the length of the square is 5 squares then
3+3+5+5 = 16 units for perimeter
for area = length x width
since length = 5 and width = 3 then
5x3=15
so area is 15 square units
Consider the function graphed below.
What is the average rate of change of the function over the interval [1, 3] ?
A.36
B. 48
C.72
D.96
Answer:
A. 96
Step-by-step explanation:
By using slope formula we got that average rate of change of the function over the interval [1, 3] is 48 .
What is the average rate of change?the rate at which one variable of a function changes in relationship to another variable is called average rate of change.
Here we can see in graph that
when x =1 y=12
and when x= 3 ,y=108
Now we know that rate of change is same as slope of straight line passing through that points
So average rate of change can be calculated as
[tex]=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]=\frac{108-12}{3-1}\\\\[/tex]
[tex]\frac{96}{2}[/tex]
=48
By using slope formula we got that average rate of change of the function over the interval [1, 3] is 48 .

Daniel puts some wheat flour into an empty bowl. Then he add 2/3 cup rye flour to make a total of 2 5/12 cups of flour. How much wheat flour is in the bowl.
Answer:
1 3/4 cups of wheat flour is in the bowl
Step-by-step explanation:
x + 2/3 = 2 5/12
First, convert the 2/3 to 12ths by multiplying numerator and denominator by 4 = 8/12
Then convert the 2 5/12 to an improper fraction 29/12
x + 8/12 = 29/12
subtract 8/12 from both sides
x = 21/12 = 1 9/12 = 1 3/4
Ramps in a parking garage need to be safe and steep. The maximum safe incline for a ramp at 8.5°. Is this ramp safe? Explain how you know using your math to justify your answer.
NEED ASAP PLEASE
Answer:
No. It is not safe.
Step-by-step explanation:
If the maximum safe incline for a ramp is said to be 8.5°, it means that the incline of any ramp that is greater than 8.5° is not safe.
Let's find the angle measure of the incline in the diagram given to ascertain whether it is safe or not.
Opposite side to angle of inclination = 20
Adjacent side to angle of inclination = 100
Apply the trigonometric function, TOA, which is:
Tan θ = Opp/Adjacent
Tan θ = 20/100
Tan θ = 0.2
θ = Tan^{-1}(0.2)
θ = 11.3099325° ≈ 11.3°
Angle of inclination for the ramp shown = 11.3°.
This is not safe because it has exceeded the maximum safe incline for a ramp which should be 8.5° maximum.

Find the total surface area of the
following prism:
5 cm
5 cm
5 cm
5 cm
10 cm
5 cm
apothem = 3.6 cm
SA = [ ? ] cm2
Answer:
Total surface area = 340 cm²
Step-by-step explanation:
Surface area of the given prism = Area of two bases + Area of its lateral surfaces
Area of pentagonal base = [tex]\frac{1}{2}(\text{Apothem)}(\text{Perimeter})[/tex]
= [tex]\frac{1}{2}(3.6)(5\times 5)[/tex]
= 45 cm²
Area of the lateral sides of the prism = Perimeter of the pentagonal base × height
= (5×5)×10
= 250 cm²
Total surface area of the prism = 2(45) + 250
= 90 + 250
= 340 cm²

С
D
y = 3.2 – 4
Answer:
y = 3x + 12
Step-by-step explanation:
Slope (m) = 24-9/4-(-1)
= 25/5
= 3
Using point (-1 , 9)
y - y1 = m (x - x1)
y - 9 = 3 (x - -1)
y - 9 = 3 (x + 1)
y - 9 = 3x + 3
y = 3x + 3 + 9
y = 3x + 12

Rounding to the first decimal place, calculate the mean for the following distribution of homicide rates in the 12 metropolitan areas with the lowest homicide rates (homicides per 100,000 population) in the U.S. in 2017.
Mesa, AZ: 4.1 Seattle, WA: 3.8 Portland, OR (tie): 3.4 New York, NY (tie): 3.4 Virginia Beach, VA: 3.3 San Jose, CA: 3.1 El Paso, TX: 2.9 Austin, TX: 2.6 San Diego, CA: 2.4 Suffolk County, Long Island, NY: 2.2 Montgomery County, MD: 2.0 Fairfax, VA: 1.7
Solution :
Given :
X = homicide rate (homicides per 100,00 population)
n = 12 = metropolitan areas
Area X (homicides per 100,000 population)
Mesa, AZ 4.1
Seattle, WA 3.8
Portland, OR (tie) 3.4
New York, NY(tie) 3.4
Virginia beach, VA 3.3
San Jose, CA 3.1
EI, Paso, TX 2.6
Austin, TX 2.6
San Diago, CA 2.4
Suffolk County 2.2
Montgomery, MD 2.0
Fairfax, VA 1.7
Therefore, the mean of X = [tex]$\bar X = \frac{\sum X_i}{n}$[/tex]
[tex]$=\frac{34.9}{12}$[/tex]
= 2.9
Therefore, the mean of homicide rater in the 12 metropolitan areas is 2.9 homicide per 100,000 population.
