Answer:
13
Step-by-step explanation:
So the concept is that co-interior angles add up to 180 in parallel line. This means:
3x + 9 + 9x + 15 = 180
So we solve for x.
12x + 24 = 180 ( What I did was simplifying the equation).
12x + 24 - 24 = 180 - 24
12x / 12= 156 / 12
x = 13

In 2010, the population of a city was 168,000. From 2010 to 2015, the population grew by 7%. From 2015 to 2020, it fell by 6%. How much did the population decrease from 2015 to 2020, to the nearest 100 people?
Answers
Answer:
169,000 people
Step-by-step explanation:
increase from 2010-2015:
168000/100 = 1680 = 1%
1680 x 7 = 11,760 people
population at 2015 = 168000+11760 = 179,760
decrease from 2015-2020:
179760/100 = 1797.6 = 1%
1797.6 x 6 = 10,785.6 people
population at 2020 = 179760-10787.6 = 168,974.4 people
rounded to the nearest 100 = 169,000 people

What are the coordinates of F after a reflection over the line y=1? Give your answer in the format (#,#)
Answers
Answer:
So for the coorfinates of F, you have to see how far it is from y=1. The F is 2 points under the 1 so you have to count 2 above the 1. So the point would be (7,3). Same for the other ones. For example like D. It's 2 above 1 so its going to be 2 under which would result in (1, -1)

How much force is needed to push a 10kg ball to an acceleration of 0.8 m/s2?
Answers
Answer:
Mass of the object (m)= 10kg
Acceleration of the object (a)= 2m/s^2
Force acting on the object (F)= ?
Solution
F = m × a
F = 10 × 2
F= 20N
The force acting on the object is 20N.
Step-by-step explanation:
8N of force is needed to push a 10kg ball to an acceleration of 0.8 m/s²
What is Force?Force is an influence that can change the motion of an object.
Given,
Mass of the object (m)= 10kg
Acceleration of the object (a)= 0.8m/s²
We need to find Force acting on the object (F)= ?
Force=Mass ×Acceleration
F = m × a
Plug in the values of mass and acceleration
F =10 × 0.8
F= 8N
Hence, The force acting on the object is 8N.

One angle of an isosceles triangle is known to be 68°. What would be one of the other angles?
a 44°
b 55°
c 66°
d 112°
Answers
Answer:
44
Step-by-step explanation:
Isosceles triangles have two angles that are equal. If the two equal angles are 68
We have 68, 68, and an unknown angle x
They add to 180
68+68+x = 180
136+x=180
x =180-136
