Answer:
The area of a circle is equal to pi times the radius squared so that means the radius of this circle is the square root of. 25!that means the radius is 5
82
The sum of the three angles is 180. One is given and the other we can figure out because it forms a straight line (180) with the angle to the left outside. The outside angle is 117, so 180-117 is 63.
So then add up the 3 angles in the triangle
63+35+y=180
y= 82
Answer:
equivalent = 30w 30(w) 30*w
the rest are non equivalent
Answer:
Step-by-step explanation:
Let the distance be d
<u>Then the time in travel is</u>
- d/60 one way, d/50 on return
<u>The round trip would take 1/2 hours longer if the average speed was 55 mph</u>
- d/60 + d/50 = 2d/55 + 1/2
- d/60 + d/50 - 2d/55 = 1/2
LCM(60,50,55) = 11*12*5*5 = 3300
- 55d/3300 + 66d/3300 - 120d/3300 = 1/2
- d/3300= 1/2
- d = 1650 miles
Answer:
Step-by-step explanation:
125 miles / 150 minutes = 300 miles / x Criss multiply
Notice that the numerators both have the same units -- miles. Proportions should always be set up that way.
125 x = 150 * 300 Combine the right
125x = 45000 Divide by 125
x = 45000/125
x = 360 more minutes which is 6 hours.
