Solution:
we are given that
Both circle Q and circle R have a central angle measuring 140°. The area of circle Q's sector is 25π m^2, and the area of circle R's sector is 49π m^2.
we have been asked to find the ratio of the radius of circle Q to the radius of circle R?
As we know that
Area of the sector is directly proportional to square of radius. So we can write

just makes sense
Answer:
22.7%
Explanation:
Given that last year stock for company A was $7200
The stock for company B last year was worth $3510
Stock in company A decreased by 24%
This means the new value of stock for company A became;
(100-24)/100 *$7200
76/100*$7200
0.76*7200 =$5472
Stock in company B decreased by 20%
This means the new value of stock for company B became;
(100-20)/100 *$3510
80/100*$3510
0.8*$3510
$2808
Original investors stock value was = $7200+$3510 =$10710
New investors stock value is = $5472+$2808=$8280
Decrease in value of stock = $10710-$8280 =$2430
percentage decrease in stock value = decrease in stock/original value of stock *100%
=2430/10710 *100 =22.689
=22.7%
Answer:
x = 5 unit
Step-by-step explanation:
The given figure represent the theorem of circle,
It two chords of circle intersect outside or inside when produce, then
AP × PB = DP × PC
SO , from given data we can find the X
Now, (X + 4) × 4 = (9 + 3) × 3
Or, X + 4 = 
Or, X + 4 = 
Or, X = 9 - 4
∴ X = 5 unit
Answer:
3(x-10)(x-6)
Step-by-step explanation:
3(x²-16x+60)
60 16
-10 × -6 -10 + -6
3(x-10)(x-6)
