If he travels 5/2 miles in 15 mins, then in 1 min he will travel 5/2 ÷ 15 = 1/6 miles and it will take him 15 ÷ 5/2 = 6 mins to travel 1 mile.
Answer:
f(t) = 15 + 160 + 1
Step-by-step explanation:
it said that t= 4 and because the t is after the 40 you would times 40 by 4 to get 160. Then you add them all up and there you go you got your velocity and speed.
Lateral area of the cone is given by:
LA=πr√(h²+r²)
where:
h=height
r=radius
Given that LA=287.5 yd² and r=(15/2) yds, then the height will be:
287.5=7.5π√(h²+7.5²)
solving for h we get:
(287.5/7.5π)²=h²+7.5²
thus
h²=(287.5/7.5π)²-7.5²
h²=63.1851597
To get the slant height we use Pythagorean theorem.
c²=a²+b²
a²=h², b²=7.5²
thus
c²=h²+7.5²
c²=63.1851597+56.25
c²=119.4351597
c=10.92864~10.9 yards
Answer:
Scale factor = 
Step-by-step explanation:
Perimeter of the actual flag = 22 in.
Perimeter of the scale drawing of the flag = 11 in.
Since, perimeter of a triangle = Sum of all three sides of the given triangle
Therefore, scale factor of the drawing
= 
= 
= 
=
Therefore, scale factor of the drawing will be .
Each side of the scaled triangle will be half of the actual triangle.
