Answer:
20 is 1/10 of 200.
Step-by-step explanation:
100*(1/10) = 10
200*(1/10) = 20
Since 100 times 1/10 is 10, all you have to do is double it. So now, 200 times 1/10 is 20.
:) Hope this helps!
I am to believe that his score was 70.
since mike scored 15 less than 85 i had suspected it was 70

Step-by-step explanation:
C.converse of the corresponding angles postulate
∠1 = 58° ( alternate angles )
HOPE THIS HELPS:)
STAY SAFE
∠1 and ∠2 form a straight angle and are supplementary, thus
∠2 = 180° - 58° = 122°
The correct answer is B) 9 m.
The measure of the sector of circle R is 32π/9 m. The measure of the central angle is 80°. This means that the sector is 80/360 = 2/9 of the circle. The area of a circle is given by A=πr², so the area of the sector is A=2/9πr². To verify this, 2/9π(4²) = 2/9π(16) = 32π/9.
Using this same formula for circle S, we will work backward to find the radius:
18π = 2/9πr²
Multiply both sides by 9:
18*9π = 2πr²
162π = 2πr²
Divide both sides by 2π:
162π/2π = 2πr²/2π
81 = r²
Take the square root of both sides:
√81 = √r²
9 = r
