Answer:
Step-by-step explanation:
we know the slope is 15, and contains these points (-10,-5)
y=15x+b
Plug in x and y with those points.
-5=15(-10)+b
-5=-150+b
b=145
The equation is y=15x+145
Well, this is really simple math.
Divide 7 by 15.
7/15 = 0.46666666666
To make it simple, round to the nearest hundredths.
7/15 = 0.47
Answer:
Option (A)
Step-by-step explanation:
One side of the given triangle is a diameter of the semicircle given.
Measure of the diameter = 10 units
Total area of the semicircle = 
= 
= 39.27 square units
Area of the right triangle = 
= 
= 24 square units
Area of the shaded region = Area of the semicircle - Area of the right triangle
= 39.27 - 24
= 15.27 square units
≈ 15 square units
Therefore, option (A) will be the answer.
Answer:
Yes
Step-by-step explanation:
Since the triangles have two congruent angles, the third angle is also congruent.
The sides of one triangle are proportional to the corresponding sides of the other triangle.
Answer:
21
Step-by-step explanation:

Multiplying both sides by 7, we get

The two 7s on the left cancel out to give 1, so
