Answer: y is equal to 3.89,

Step-by-step explanation: This question can be solved using the theorem of the power of a point.

The power of a point Theorem states that if a two lines intercept at a point that is intersect with the center of the circle, the lines will create either one segment (S) or two segments (s1 and s2). And the multiplication of each segment equal, which is s1s2 for line one is equal to s1s2 for line two.

Therefore for the diagram.

Using the power of a point Theorem;

9 ×y = 5 × 7

9y = 35

Therefore;

y = 35 ÷ 9 = 3.88889

y = 3.89

5 * 7 = 9y
35 = 9y

Mary spent 3/4 of her money on a jacket. She spent 1/4 of the remainder on a shirt. The jacket cost $33 more than the shirt. How
Leviafan [203]
$49.50 the jacket costs this because her total amount was $66. to find total money I said 3/4x - 1/4x = $33 so 1/2x =$33 and x= $66. then multiply the total by 3/4 to get $49.50

The sum of the areas of two circles is 8pie square meters. Find the length of a radius of each circle ifone of them is twice as
NeX [460]
Nice

area=pir^2
the areas are
pir^2+pi(2r)^2
they add to 8pi

8pi=pir^2+pi(2r)^2
undistribute pi
8pi=pi(r^2+(2r)^2)
divide both sides by pi
8=r^2+(2r)^2
expand
8=r^2+4r^2
add
8=5r^2
divide by 5
8/5=r^2
sqrt both sides
√(8/5)=r
double since it is double
2√(8/5) is radius of bigger aka (4√10)/5

radius=(4√10)/5
