The most important thing in this problem is understanding and then dividing the given units properly. The first thing that is given is that the CD makes 58 1/2 revolutions in 3/4 minutes. We have to first simplify the number of revolutions made by the CD. This will make the problem in hand very easy.
Number of revolutions made by the CD = 58 1/2
= 117/2
Then
The unit rate = (117/2)/(3/4)
= (117 * 4)/(2 * 3)
= (117 * 2)/3
= 39 * 2
78
So the unit rate is 78 revolutions per minute.
Since both the triangles are similar,
(y-2)/(y+4) = 4/8
8(y-2) = 4(y+4)
8y - 16 = 4y + 16
8y - 4y = 16 + 16
4y = 32
y = 32/4
y = 8
The perimeter of triangle PQR:
4 + 6 + (8-2)
= 10 + 6
= 16 ft.
2/3 * 85/1 = 170/3
170/3 = 56 2/3
Your answer is 56 2/3
Answer:
°
Step-by-step explanation:
"Theorem 9-13: The measure of an angle formed by two secants, two tangents, or a secant and a tangent drawn from a point outside the circle is equal to half the difference of the measures of the intercepted arcs."
Basically no matter what other circle, secant or tangent you get, you just use the formula 
If you need the outer angle, just put the other angles in and solve
If you need the far or near point angle, re-arrange the formula to get that value.
Answer:
4 5/8
Step-by-step explanation:
Given function:
- ruler measure ( between 4 and 5 )
<u><em>Find the fraction area:</em></u>
- ok so let see what we know about this..
- middle of 4 and 5 also seems like in the middle of 4 1/2 to 4 3/4
- let convert these fraction into a denominator of 8..
- 2/4=4/8
- 3/4=6/8
- find the middle of 4/8 and 6/8
Therefore, the blue line is 4 5/8 inches long.
