Answer:
The distance travel by cyclist in 20 seconds is 528 feet .
Step-by-step explanation:
Given as :
The speed of cyclist riding bike = s = 18 miles per hour
Let The distance cover by cyclist in 20 seconds = d feet per sec
<u>Now, According to question</u>
∵ 1 miles = 5280 feet
∴ 18 miles = 5280 × 18 = 95,040 feet
So, The speed of cyclist in feet per hour = 95,040 feet per hour
<u>Again,</u>
∵ 1 hours = 3600 seconds
So, The speed of cyclist in feet per sec = ft/sec
∴ The speed of cyclist in feet per sec = 26.4 feet per second
<u>Again</u>
∵ In 1 sec the distance cover by cyclist = 26.4 feet
∴ In 20 sec the distance cover by cyclist = 26.4 × 20 feet
i.e In 20 sec the distance cover by cyclist = 528 feet
Hence, The distance travel by cyclist in 20 seconds is 528 feet . Answer
Answer: 1080
Determine the values of b1, b2, and b3, the sides of the triangular base. Also determine the value of h, the height of the triangular base and l, the length of the prism (the length between the bases).
The sides of the triangular base are:
b1 = 13 in.
b2 = 14 in.
b3 = 15 in.
The triangular base is a right triangle, and so the height is one of our sides. We will use
h = 12 in.
The length of the prism is
l = 20 in.
total surface area = bh + (b1+b2+b3)*l
bh = 12*20 = 240
l * (b1+b2+b3) = 20*(13 + 14+ 15) = 840
TSA = bh + l * (b1 + b2 + b3) = 240 + 840 = 1080
