Tell whether the angles are complementary or supplementary. Then find the value of x.
Answers
the angles are complementary because they add up to 90° because of the red square. x=20
Step-by-step explanation:
4x-5+15=90
4x+10=90 subtract 10 from each side
then you get left with 4x=80
divide 4 from each side then you get left with x=20 and to check just substitute 20 where x is so 4(20)-5= 80-5=75 +15=90.

If the regular price is $900 and the discount rate is 30%, what is the sale price?
Answers
Answer:
$630
Step-by-step explanation:
First, multiply the original price by the decimal of the percentage:
900 x 0.30 = 270
Since this is a discount we subtract the original amount and the discount amount. If it we were calculating tax or a raised price, you would add. But were lowering the price so:
900 - 270 = 630
Therefore, it’s 630

50%
64%
PLS NO LINK thanks :)
Answers
Answer:
Step-by-step explanation:
here you go it in there
Answer:
Probability is 64%
Step-by-step explanation:
Given the smaller circle which is shaded whose radius is denoted by r and the largest circle whose radius is denoted by R
r = 3 inches
R = 5 inches
Step 1 : To calculate the area of shaded region.
Area of circle =
⇒ Area =
= square inches
Step 2 : To calculate the area of larger circle.
Area of circle =
⇒ Area =
= square inches
Step 3 : Calculate the probability that a point chosen from shaded region
Probability = Area of shaded region/Area of larger circle.
= /
=
= 0.36 = 36%
Step 4 : calculate the probability that a point chosen inside the larger circle is not in shaded region.
Probability = 1 - 0.36
= 0.64 = 64%
Hence the probability is 64%
