One angle, Angle A = 80° find the other angle, Angle B
Hint: They are formed on a line.
If 2 angles are formed on a line, then they make a supplementary / linear pair of angles, i.e, both the angles form 180°.
Here,
Angle A = 80°
Angle B = x°
So,
Angle A + Angle B = 180°
80° + x° = 180°
x° = 180° - 80°
x° = 100°
=》 Angle B = 100°

Estimate the line of best fit using two points on the line.
Answer: i think it's b
Answer:
C.
Step-by-step explanation:
A and D are immediately wrong since the line is increasing.
Using the formula of rise over run, we can find the slope. We then use 40 as the rise and 5 as the run
40/5 is 8.
We can now put 8 as the slope in the y=mx+b equation. We can see the line intersect at 20 at the y-axis, which makes 20 the y-intercept. We can now insert that into the b part of the equation. This leaves us with y=8x+20.
Jack rode his bike 30 miles 5 hours. At this rate, how long would it take jack to ride one mile?
Answer:
36 seconds
Step-by-step explanation:
30 / (5 x 60) = 0.01
0.01 hours = 0.6 minutes
0.6 minutes = 36 seconds
Answer:
10 minutes
Step-by-step explanation:
First, we need to convert hours to minutes. 5 x 60 = 300.
300 minutes for 30 miles.
Next, divide both numbers by something to equal 1. (Divide it by 30, because we are trying to get 30 to 1.)
300 divided by 30 = 10
30 divided by 30 = 1
So, it would take Jack 10 minutes to ride 1 mile.

Step-by-step explanation:
Mr. Miranda borrowed $8,800 for 12 months at simple interest to pay for a new swimming pool. If Mr. Miranda paid the bank a total of $10,287.20, what was the simple interest rate of the loan?
85.5%
1.4%
16.9%
14.5%
The answer would be b, or 1.4%.
The simple interest rate of the loan will be 16.9%. Then the correct option is C.
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
A = P + (PRT)/100
Where P is the principal, R is the rate of interest, and T is the time.
Mr. Miranda acquired $8,800 for a considerable length of time at basic interest to pay for another pool. On the off chance that Mr. Miranda paid the bank a sum of $10,287.20.
The simple interest rate of the loan will be given as,
10,287.20 = 8,800 + [(8,800 x r x 12) / (100 x 12)]
1,487.2 x 100 = 88r
r = (1487.2 / 88) x 100
r = 0.169 x 100
r = 16.9%
The simple interest rate of the loan will be 16.9%. Then the correct option is C.

The midpoint of AB is (-9, -10) and the coordinates of point A are (-1, 9) what are the coordinates of point B?
Answer:
B = (-17, -29)
Step-by-step explanation:
The midpoint (M) of AB is ...
M = (A +B)/2
Solving for B gives ...
B = 2M -A = 2(-9, -10) -(-1, 9) = (-18+1, -20 -9)
B = (-17, -29)

Answer:
x = -3 or x = 2
Step-by-step explanation:
Given that,
x ( x - 2 ) + 3 ( x - 2 ) = 0
( x + 3 ) ( x - 2 ) = 0
So,
( x + 3 ) = 0 ( x - 2 ) = 0
x + 3 = 0 x - 2 = 0
x = 0 -3 x = 0 + 2
x = (-3) or x = 2
