∠DOC is the average of the given angle values,
(170° +44°)/2 = 107°
∠DOB is the supplement to that,
180° -107° = 73°
The appropriate choice is
B) 73°
Answer:
0 —> 15
1 —> 13.75
2 —> 12.5
3 —> 11.25
Step-by-step explanation:
Every time she drives for 1 hour, the car uses up 1.25 gallons of gas. If she fills it up and doesn't drive anywhere, the car will still be full with 15 gallons. If she drives for an hour, you would need to subtract 1.25 from 15 which would equal 13.75.
Then if she drives another hour, then you would subtract another 1.25 from 13.75.
Or a quicker way to do it would be if you multiply the number of hours driven by the gallons used per hour then subtract it from the filled up tank.... So for example if she drove 3 hours —> 3•1.25=3.75 then 15-3.75=11.25
Answer:
Therefore the area of parallelogram is 32 cm².
Step-by-step explanation:
Given:
[] ABCD is a Parallelogram .........Given
AB = 4 cm = Base
BC = 10 cm
CE = Height of Parallelogram
To Find:
area of parallelogram = ?
Solution:
In Right angle triangle BEC by Pythagoras theorem we have
Substituting the values we get
Which is the Height of Parallelogram
Now, area of parallelogram given by
Substituting the values we get
Therefore the area of parallelogram is 32 cm².
Answer:
6.75 ft^2
Step-by-step explanation:
The area of the seat can be calculated as follows
a + b/2 × h
6+3/2 × 1.5
9/2 × 1.5
4.5× 1.5
= 6.75 ft^2
Hence the area of the seat is 6.75ft^2
Answer:
1312.5 minutes
Step-by-step explanation:
For her phone service, Lucy pays a monthly fee of $25, and she pays an additional $0.06 per minute of use. The least she has been charged in a month Is $103.72
What are the possible numbers of minutes she has used her phone in a month?
Use m for the number of minutes, and solve your inequality for m.
The term least = ≥ = greater than or equal to
Our inequality equation is given as:
$25 + $0.06 × m ≥ $103.72
25 + 0.06m ≥ 103.72
0.06m ≥ 103.72 - 25
0.06m≥ 78.75
m ≥ 78.75/0.06
m ≥ 1312.5 minutes
The possible number of minutes she used is 1312.5 minutes
