Answer:
Step-by-step explanation:
Part A: You can only use Pythagorean's Theorem on a right triangle.
Part B: The side across from the right angle is the hypotenuse. It has a length of 15.
Part C: To find the missing side using Pythagorean's Theorem:
and
and
and
a = 10.20
$11 per hour. Divide 82.5 by 7.5 and you get how much money she earns in an hour (11 dollars)
Answer:
c) r = 4x + 2y
Step-by-step explanation:
∑y
-3 + 5 =2
∑x
1 + 3 = 4
r = 4x + 2y
Answer:
7
cm²
Step-by-step explanation:
First, find the area of the big circle with the formula A =
r²
A =
(3)²
A = 9
Now, we can find the areas of the smaller circles. Since they have the same radius, they are congruent (will have the same area)
A =
r²
A =
(1)²
A = 
Now, we will subtract the areas of the smaller circles from the area of the big circle to find the area of the shaded region:
9
-
-
= 7
So, the area of the shaded region is 7
cm²
Subtract 4x on both sides then divide by negative to all three numbers and your answer will be y = 1/2x - 3/2
