Answer:
7 hours=455 miles 6 hours=3
Step-by-step explanation:
FIrst, lets find how many mph he is at. 845/13= 65mph
So, if he goes for 7 hours, he would do 7*65, which is 455 miles
Then we can do 6*65 which is 390
Answer:
2.25
Step-by-step explanation:
Just add it up, IDK if it's the full answer because you had 3 dots (...).
At rest
mg=836 N
as g=9.8
m=836/9.8=85.30 kg
when going up,
mg+ma=935N
ma=935-836= 99N
a=99/85.30 = 1.16 m/s².
that is the acceleration of elevator
pls marks as brainliest answer
The given function is

According to this function, the starting height of the rocket is 20 feet because that's the initial condition of the problem stated by the independent term.
Additionally, we find the maximum height by calculating the vertex of the function V(h,k).

Where a = -16 and b = 300.

Then, we find k by evaluating the function

Hence, the maximum height is 1426.25 feet.
At last, to know the time need to hit the ground, we just use h=9.375 and we multiply it by 2

Hence, the rocket hits the ground after 18.75 seconds.
Answer:
? = 55
Step-by-step explanation:
if we put the triangles onto of each other
side CT is on top of TR
126 ÷ 70 = 1.8
70 × 1.8 = 126
BT is on top of TS
so,
99 ÷ ? = 1.8
99 = 1.8 × ?
99 ÷ 1.8 = ?
55 = ?
55 × 1.8 = 99
Hoped i helped :)
