Yes her number line make sense in why is because the way she sat it up was the right way..
Answer:
Option (4)
Step-by-step explanation:
By the property of exterior angle of a triangle,
"Exterior angle of a triangle is equal to the sum of two opposite interior angles."
In the triangle ABC,
∠ACD is an exterior angle and ∠BAC and ∠ABC are the opposite interior angles.
m∠ACD = m∠BAC + m∠ABC
95° = m∠BAC + m∠ABC
Therefore, Option (4) will be the correct option.
1)
We calculate the total number of new light fixtures.
Total number of new light fixtures=(24 new fixtures/1 floor)(4 floors)=
=96 new fixtures.
2)
We calculate the total number of work hours
20 minutes=20 minutes * (1 hour/60 minutes)=1/3 hour.
1 electrician-----------1/3 hour----------1 new fixture
2 electricians---------- x ------------96 new fixtures
1 elec.*1/3 hour*96 nex fixtures=2 elect. * x * 1 new fixture.
x=(1 elec. *1/3 hour * 96 nex litght fixtures) / (2 elect.* 1 new fixture)=
=16 hours.
3)
We calculate the total number of days that it take two electricians to complete the installations.
1 day-------------8 work hours
x------------------16 work hours
x=(1 day* 16 work hours) / (8 work hours)=2 days
Answer: 2 days.
The dimensions of the scale drawing is length = 168 inches and width = 126 inches
<h3>How useful is a scale drawing?</h3>
Scale drawing helps to represent surfaces on earth in a paper by either enlarging its dimension, reducing its dimension by a constant factor called the scale factor.
The conversion or scale factor is 21 inches = 4 meters
If 21 inches = 4 meters,
then 1 meter = 21/4 inches
32 meters inches = 32 x 21/4 = 168 inches
24 meters = 24 x 21/4 = 126 inches.
In conclusion, length of the scale drawing is 168 inches and width of the scale drawing iss 126 inches

Answer:
90
Step-by-step explanation:
Step 1: Given data
Side of the rectangular prism (s): 3
Height of the rectangular prism (h): 6
Step 2: Calculate the surface area (SA) of the base
We will use the following expression, replacing the values for s and h.
SA = 2 × s² + 4 × s × h
SA = 2 × 3² + 4 × 3 × 6 = 90
The units are not provided but the SA should have the same units as s and h, but raised to the power of 2.
