The answer:
the full question is as follow:
<span>Point F is on circle C. What is the length of line segment GF?

12.5 units
15.0 units
17.5 units
20.0 units

according to the image, GF= GC + CF

CF is the radius of the circle, so it is CF =CE = 7.5
all that we want to find is the value of GC
let's consider the triangle GEC. This is a right triangle, so for finding GC, we can apply Pythagorean theorem

that is, GE² + EC² = GC², and from this, we have GC = sqrt(</span>GE² + EC² )

GC = sqrt(10² + 7.5² )=sqrt(56.25)=12.5
<span>
therefore, </span>GF= GC + CF=12.5 + 7.5 = 20.0
the answer is 20.0 units

y in the first equation because y is already by itself. All you have to do is move the -3x to the other side.

Answer:

Step-by-step explanation:

1. Eggs are sold at a price of P 105.00 per dozen.

Rate = $\frac{1}{105}$

2. The carpentry job can be done by 3 carpenters in 4 days.

Rate at which each carpenter works = $\frac{4}{3}$ = 1 $\frac{1}{3}$ days

This shows that each carpenter worked for an average of 1.3333 days to complete the job.

3. Five tickets are sold at P 600.00

The price for one ticket = $\frac{600}{5}$

= 120

One ticket is sold for P 120.00.

4. The dollar's rate is P 52.00.

This implies that;

1 dollar = P 52.00

dollar rate = $\frac{1}{52}$

5. The ratio of water to milk in the recipe is 1 to 4.

This implies that to 1 measure of water, 4 measures of milk is used in the recipe.

rate = $\frac{1}{4}$
