Use proportions and use letters for unknown measurements
H=hour
10h+7=32 would be the best equation. Hope this helps!
Answer:
- Q11 - 12 sides
- Q12 - 10 sides
Step-by-step explanation:
<u>Use the formula for sum of interior angles of a regular polygon:</u>
<u>Each angle A measures:</u>
- S/n = 180(n - 2)/n
- A = 180(n - 2)n
- An = 180n - 360
- (180 - A)n = 360
- n = 360/(180 - A)
<h3>Question 11</h3>
<u>Each angle is 150, then finding n:</u>
- n = 360/(180 - 150)
- n = 360/30
- n = 12
<h3>Question 12</h3>
<u>Each angle is 144, find n:</u>
- n = 360/(180 - 144)
- n = 360/36
- n = 10
Answer:
A)100 in
Step-by-step explanation:
Given: Radius of circular table= 16 inches
Now, solving for circumference of the tabletop.
Remember, circumference of circle= 
we know pi= 3.14
∴ Circumference= 
⇒ Circumference of circular tabletop= 100.48 in ≅ 
∴ Circumference of circular tabletop is 100 in.
Answer: There is an important difference between the way counts are viewed in ratio to that in fractions. The ratio of boys : girls →4:5 so you have 4 boys and 5 girls making the whole count 4+5=9 in its simplest form. ... girls →59 of the whole.
Step-by-step explanation: have a good day!
