Can someone help me with these two problems?

Sav [38]

Answer:

C. 38°

D. 30°

Step-by-step explanation:

The relevant relation in both cases is the inscribed angle measures half the measure of the arc it intercepts.

C. Angle TSQ intercepts arc TQ, so the measure of arc TQ is 2(86.5°) = 173°. The measure of arc TR is the difference between the measures of arcs TQ and RQ, so is ...

arc TR = 173° -135° = 38°

D. Inscribed angle PQR intercepts arc PR, so is half its measure.

angle PQR = 60°/2 = 30°

Nitella [24]

Answer:

A. What is the percent of change from last year to this year.

Answer: The percent of change from last year to this year is:

$\frac{10.00 - 8.50}{8.50} \times 100$

$\frac{1.50}{8.50} \times 100$

$17.65 \%$

Therefore, the percent change from last year to this year is 17.65%

B. Is this a percent increase or decrease?

Answer: This is a percent increase.

C. If you have 25% off coupon to use on 10.00 ticket what is the cost?

Answer: The 25% of 10.00 is given below:

$\frac{25}{100} \times 10.00$

$0.25 \times 10.00$

$2.5$

Therefore, the cost is:

$10.00 -2.5 =7.5$

Solve the equation. Check your solution.<br> -0.5=y-1<br> help

nekit [7.7K]

Answer:

y=0.5

Step-by-step explanation:

$- 0.5 = y - 1 \\ - 0.5 \ + 1 = y \\ 0.5 = y$

Check by substitution :

$- 0.5 = y - 1 \\ - 0.5 = (0.5) - 1 \\ - 0.5 = - 0.5 \\$
