Answer:
A = 108 in.²
Step-by-step explanation:
The figure can be decomposed into 3 rectangles.
✔️Area of rectangle 1 = L*W
L = 8 in.
W = 6 in.
Area = 8*6 = 48 in.²
✔️Area of rectangle 2 = L*W
L = 10 in.
W = 4 in.
Area = 10*4 = 40 in.²
✔️Area of rectangle 3 = L*W
L = 5 in.
W = 4 in.
Area = 5*4 = 20 in.
✔️Area of the irregular figure = 48 + 40 + 20 = 108 in.²
Answer:
-8.228 and -13.416
Step-by-step explanation:
math
The first checkpoint = 1check
the second checkpoint = 2check
complete distance = f
1check = 2/5 (2check)
2check = 1/4 (f)
then
1check = 2/5 * 1/4 (f)
1check = 1/10 f
the distance of the first check point is 1/10 of the distance of race
Answer:
15h +5
Step-by-step explanation:
let h be the total hours.
the total cost for h hours would be 15h
a on time 5 dollars for a jacket
expression for total cost 15h +5
Find the circumference to see how much of the wheel is touhing the ground
c=2pir
c=2pi1.9
c=2.8pi
2.8pi=distance per 1 rotation
number of rotations per second times 2.8pi=12feet per second
dvide both sides by 2.8pi
number of rorations per second=12/2.8pi
number of roations per second=6/1.4pi
number of roations per second=3/0.7pi
number of roations per second=30/7pi
aprox
number of roations per second=1.364 rotations per second
