Segments PR and QT are diameters of Circle A.

Dafna11 [192]

Answer:

C. 320

Step-by-step explanation:

Given:

PR and QT are diameters

As we can see in the photo, PR and QR are perpendicular with each other at the angle PAQ => the angle QAR = 90°

=> arc PR = 360°/2 = 180°

=> mTAU = 180° - mRAS -mSAT - mPAU = 180° - 50° + 40° + 40° = 50°

Hence, mPRU = mRAS + mSAT + mTAU + arc PQ

= 50° + 40° + 50° + 180°

= 320°

A stockbroker earns a base salary of 40000 dollar plus 5%of the total value of the stocks,mutual funds , and other investments t

lisabon 2012 [21]

Well his salary is $40,000 dollars.

$72,750 - $40,000 = $32,750

This means that 5% of the value of investments he had sold was equal to $32,750.

$\frac { 1 }{ 20 } \times I=32750\\ \\ 20\times \frac { 1 }{ 20 } \times I=20\times 32750\\ \\ \therefore \quad I=655000$

The stockbroker sold $655,000 worth of investments.

The ratio of North American butterflies to South American butterflies at a butterfly park is 5:3. The ratio of South American bu

Natalija [7]

Answer: There are 12 European butterflies.

Step-by-step explanation:

Let be "s" the number of South American butterflies at the butterfly park.

Since the ratio of North American butterflies to South American butterflies at a butterfly park is 5:3 and the number of North American butterflies at the butterfly park is 30, you can write the folllowing proportion:

$\frac{5}{3}=\frac{30}{s}$

Solving for "s", you get:

$(s)(\frac{5}{3})=30\\\\s=(30)(\frac{3}{5})\\\\s=18$

Let be "e" the number of European butterflies at the butterfly park.

Knowing that the ratio of South American butterflies to European butterflies at the butterfly park is 3:2, and since there are 18 South American butterflies, you can write the following proportion:

$\frac{3}{2}=\frac{18}{e}$

Solving for "e", you get:

$(e)(\frac{3}{2})=18\\\\e=(18)(\frac{2}{3})\\\\e=12$
