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: 3
Step-by-step explanation: Your equation is p- (-9)=12. A negative plus a negative is a positive. So the equation is basically p+9=12. 12 minus 9 is 3 and that's the answer!
Answer:
Step-by-step explanation:
You haven't given the choices but I believe the equation below could represent the area of the circle:
(pi ~ 3.14) * (18)^2
The area for a circle is pi * radius squared, so to find the radius divide the diameter by 2.
The change in elevation is 14 meters.
The diver started at 10 meters above water but ended up 4 meters below water. This means you must add the 4 meters after passing the water line for a total elevation change of 14 meters.
