Answer:
Option A.
Step-by-step explanation:
see the attached figure with letters to better understand the problem
In this problem we have a triangle with a circle inscribed in it
so
step 1
Find the length side B.C
substitute the given values
step 2
Find the length side C.D
Remember that
therefore
step 3
Find the length side E.D
we know that
substitute the given values
step 4
Find the length side E.F
Remember that
therefore
step 5
Find the length side A.F
Remember that
therefore
step 6
Find the perimeter
Answer:
Step-by-step explanation:
The line given has a slope of 7.5 and a point at (12, 80)
Because of the slope, simply subtract 2 from the x and subtract 15 from the y to get another point, at (10, 65)
Thus, simply put your points at (10, 65) and (12, 80)
Hope it helps and let me know if you want me to elaborate.
Answer:
Area of shaded region = 422 cm²
Step-by-step explanation:
Area of rectangle = length × breadth
= 3cm × 10cm
= 30cm²
Area of circle = πr²
= 3.14 × 12²
= 3.14 × 12cm × 12cm
= 452.16 cm²
Area of shaded region = Area of circle - Area of rectangle
= (452.16 - 30) cm²
= 422 cm²
start with -9.55. then do that number plus 136.32. which is 126.77. then 82.77 for phone bill which leaves you at 44$ then divide by 4$ because thats how much a gallon is worth =. that leaves you with 11. so you can afford and put 11 gallons of gas in your car!! :)
