Given:
A figure of a circle. A secant SU and a tangent SR is drawn to the circle from the external point S.
To find:
The measure of the line segment TU.
Solution:
According to the secant tangent segment theorem, the square of tangent is equal to the product of secant and external segment of the secant.
Using secant tangent segment theorem, we get
Subtract both sides by 960.
Divide both sides by 64.
Now, the measure of the line segment TU is:
Therefore, the correct option is C.
Answer:
25X + 25Y = 1700
25X + 100Y = 3200
Step-by-step explanation:
Given that the principal of a high school spent $1700 for X desk and Y chairs at $25 each. Then, the equation will be
25X + 25Y = 1700 ....... (1)
If he had bought half the number of desk in twice the number of chairs he would have spent 1600. That is
25(X/2) + 25(2Y) = 1600
25X/2 + 50Y = 1600
Find the LCM and cross multiply
25X + 100Y = 3200 ........(2)
Answer:
.7% of the people had a mild allergic reaction
Step-by-step explanation:
42/6000 = .007
To turn the decimal into a percent, you need to move the decimal 2 spaces to the right.
.007 → 00.7 → .7%
Did everyone what she made by hours worked to find her hourly rate:
231 / 22 = 10.50 per hour
Multiply her hourly rate by number of hours:
10.50 x 40 = 420
She would earn $420
