What is the area of this composite figure?

jek_recluse [69]

Answer:

7.14 in. sq

Step-by-step explanation:

First find the area of the square; 2x2=4

Now find the area of the semi-circle; radius = 1.

1 squared= 1 Now multiply by 3.14 which equals 3.14

Now divide by 2 because it's a semi-circle, you get 1.57.

Multiply 1.57 by 2 because you have 2 semi-circles, the would equal 3.14

Add 4+3.14 and you get 7.14

The area of the composite figure is 7.14 in. sq

Tom bought a PS4 on Black Friday for 25% off. If the system sells for $399, what is the sales price of the PS4?

Delicious77 [7]

Answer:

The sales price of the PS4 is $532.

Step-by-step explanation:

The system sells for $399 after giving 25% off on a Black Friday on the sales price.

Let the sales price of the PS4 system is $x.

Then after giving 25% discount the price will become $x(1 - \frac{25}{100}) = 0.75x$

Therefore, 0.75x = 399

⇒ x = 532

Therefore, the sales price of the PS4 is $532. (Answer)

Can I get help with this question?

The answer is 157 degrees because the line segment is 180 and if <AFB is 23, you take 23 away from 180 and you should get 157. To check, add 157 to 23 or take away 157 from 180.
