Perimeter of the new triangle is 576 ft
Step-by-step explanation:
- Step 1: Given the perimeter of the right triangle = 72 ft. Find new perimeter.
Perimeter of the triangle = sum of the sides = a + b + c = 72
Each side is multiplied by 8, so new sides are 8a, 8b, 8c
⇒ New perimeter = 8a + 8b + 8c = 8(a + b + c) = 8 × 72 = 576 ft
I believe the answer is b
Answer:
360°
75° + 15t
Step-by-step explanation:
Given that the initial temperature of the oven is 75° and the temperature will increase at a rate of 15° per minute, it means that the temperature T after x minutes will be given as
T = 75 + 15x
Hence after 19 minutes, the temperature will be
= 75 + 15(19)
= 75 + 285
= 360°
After t minutes, the temperature will be
= 75° + 15t
answer is explained in above figure
