Answer: m A = 150°
well if what you are talking about is arcs, which is what it seems like, the ans for m A = 150°
Step-by-step explanation:
all of the arcs in a circle add up to 360.
so
360 - 101 - 109 = 150
150 would be your degree

-2x - 2y - 2z + 5x - 2y - 4z
Answer: 3x-4y-6z
Step-by-step explanation:
First collect the like terms and you get:
-2x + 5x - 2y - 2y - 2z - 4z
Add similar elements:
3x - 2y - 2y - 2z - 4z
And you do it again and you get: 3x-4y-2z-4z
then just take away -4z from -2z and you get: 3x-4y-6z
Given two similar triangles, what would you need to know
to find an unknown length? How would you find that
unknown length?
Answer:
There is a pattern with the ratios of corresponding sides. You can see that the measurement of each side of the first triangle divided by two is the measure of the corresponding side of the second triangle. Use patterns like this to problem solve the length of missing sides of similar triangles.
Answer:
I would need to know the length of a pair of corresponding sides, so I could set up a proportion to solve for the unknown length. I would set the ratio of the known corresponding sides equal to the unknown measure, making sure I put corresponding measures from the triangles in the same positions in the ratios. Then I would cross-multiply to solve.

The sum of two consecutive odd integers is at least 76. Find the least possible pair of integers.
n + n + 2 ≥ 76
n + n + 2 > 76
n + n + 1 > 76
n + n + 1 ≥ 76
Answer:
n + n + 2 ≥ 76Explanation:
To find odd numbers, we have to use n + n + 2
For example let the number be 1, the 1 + 2 = 3, 3 + 2 = 5.
Therefore, used: n + n + 2 expression and it should be equals or at least 76. so finally n + n + 2 ≥ 76 applies.

Answer:
y = -7x -7
explanation:
y - y₁ = m ( x - x₁ )
y - -7 = -7 ( x - 0 )
y + 7 = -7x
y = -7x -7
Or using the formula:
y = mx + b
y = -7x - 7

Find the slope and the y-intercept of the line.
3x+5y=−4
Write your answers in simplest form.
Answer:
slope = -3/5
y intercept = 4/5
Step-by-step explanation:
First, we can rearrange 3x + 5y = 4 into slope intercept form (y = mx + b) to get 5y = -3x + 4. Now we can divide by 5 to make y the subject: y = -3/5x + 4/5. The number in front of x is the slope and the number on its own is the y intercept.
slope = -3/5
y intercept = 4/5

On the map below, all numbered streets run parallel to each other. Both 3rd and 4th streets are intersected by King Avenue.
A delivery driver is driving around town and has noticed that every time he turns, it creates an angle. What are the measures of Angles X, Y, and Z on the map?
In your answer, give the measures of angles X, Y, and Z, and explain how you calculated each one.
The map is an illustration of parallel lines and a transversal
The measure of angle X is 105The measure of angle Y is 75The measure of angle Z is 105How to determine the measures of the anglesAngles X and 75 are supplementary angles.
So, we have:
X = 180 - 75
Subtract
X = 105
Angles Y and 75 are corresponding angles.
So, we have:
Y = 75
Angles X and Z are alternate exterior angles.
So, we have:
Z = X
This gives
Z = 105
Hence, the measures of angles X, Y and Z are 105, 75 and 105 degrees respectively

Show all work below to answer the following for a certain city that had a population of 150,000 in the year 2010. In 2020, the population was 185,000.
a. Find the constant rate of continuous growth, k, for this population. (Please round to 5 decimal places)
b. When will the population reach 250,000 people?
The constant rate of continuous growth, k, for this population is equal to 2.11935%. And the population will reach 250,000 people in 24.36 years.
For solving this question, you should apply the Population Growth Equation.
Population Growth EquationThe formula for the Population Growth Equation is:
[tex]P_f=P_o*(1+\frac{R}{100} )^t[/tex]
Pf= future population
Po=initial population
r=growth rate
t= time (years)
STEP 1 - Find the constant rate of continuous growth, k, for this population.
For this exercise, you have:
Pf= future population= 185,000 in 2020.
Po=initial population =150,000 in 2010.
r=growth rate= ?
t= time (years)=2020-2010=10
Then,
[tex]P_f=P_o*(1+\frac{R}{100} )^t\\ \\ 185000=150000\cdot \left(1+\frac{R}{100}\:\right)^{10}\\ \\ \left(1+\frac{R}{100}\right)^{10}=\frac{185000}{150000} \\ \\ \left(1+\frac{R}{100}\right)^{10}=\frac{37}{30}\\ \\ R=100\sqrt[10]{\frac{37}{30}}-100=2.11935\%[/tex]
STEP 2 - Find the t for population 250,000 people.
[tex]P_f=P_o*(1+\frac{R}{100} )^t\\ \\ 250000=150000\cdot \left(1+\frac{2.11935}{100}\:\right)^{10}\\ \\ \left(1+\frac{2.11935}{100}\right)^{10}=\frac{250000}{150000} \\ \\ \left(1+\frac{2.11935}{100}\right)^t=\frac{5}{3}\\ \\ t\ln \left(1+\frac{2.11935}{100}\right)=\ln \left(\frac{5}{3}\right)\\ \\ t=\frac{\ln \left(\frac{5}{3}\right)}{\ln \left(\frac{102.11935}{100}\right)}\\ \\ t=24.36[/tex]

The distance between Reeta's house and her office is 14 km. She covers 10 km 65 m by scooter, 3 km 75 m by bus and the rest on foot. How much distance does she cover by walking?
Answer:
She covered 0.86 km or 860m by walking.
Step-by-step explanation:
Given:
➮ Distance between Reeta's house and her office is 14km.
She covers 10km 65m by Scooter. Then, 3km 75m by Bus. And rest of distance covered by foot.To Find:
➮ How much distance covered by foot/walking ?
Solution:
To find the distance covered by foot = Total distance - Sum of distance covered through scooter and bus.
Sum of distance covered through scooter and bus:-
As, we know:
• 1km = 1000m
⇒ 10km = 10×1000
= 10000m
⇒ 3km = 3×1000
= 3000m
So, 10000m + 65m ➝ 10065m
3000 + 75m ➝ 3075m
➝ 10065m + 3075m
➝ 13140m
• 13140m into km:-
⇒ 13.14km
Now, Finding the distance covered by walking:
➝ 14km - 13.14km
➝ 0.86km
Hence, She covered 0.86km or 860m by walking.
