Answer:
58 seconds
Step-by-step explanation:
Given the following :
Elevation of red Kite = 140 ft off the ground
Rising rate = 7 feets per second
Elevation of blue Kite = 315 feets
Rising rate of blue Kite = 4 feets per second
Determine how long will it take for the red and blue kites to be the same height.
Let number of seconds = t
Red Kite = 140 + 7t
Blue Kite = 315 + 4t
Red Kite = Blue Kite
140 + 7t = 315 + 4t
7t - 4t = 315 - 140
3t = 175
t = 175/3
t = 58.333
t = 58s (nearest tenth(
Answer:
x=4.75
Step-by-step explanation:
16(4x-3)=8(2x+4)
16*4x-3=8*2x+4
-2x -2x
16*2x-3=8*4
multiply 8*4=32
16*4x-3=32
-16 -16
4x-3=16
+3 +3
4x=19
divide 4 by both sides
x=4.75
Answer:
The perimeter of the figure is 86.53 meters
Step-by-step explanation:
we know that
The perimeter of the figure is equal to the circumference of a semicircle, plus the sum of the legs of the right triangle
step 1
Find the circumference of a semicircle
The circumference of a semicircle is given by the formula
we have
----> the radius is half the diameter
assume
substitute
step 2
The sum of the legs of the right triangle is equal to
step 3
Perimeter of the figure
