Answer:
Bushes cost $28
Step-by-step explanation:
WE have:-
4*63 + 13b = 616 where b = cost of one bush.
252 + 13b = 616
13b = 616 - 252 = 364
b = 364/13
b = 28 (answer)
Answer:
x+x+1+x+2+x+3=190
4x+6=190
4x=184
x=46
Step-by-step explanation:
the numbers are 46&47&48&48
so your answer is 48
Answer:
f^-1(x) = x+1
Step-by-step explanation:
turn into y = x-1
1. Flip x to y and y to x
x = y-1
2. isolate y
x+1 = y
using a graph you can find it by reflecting x-1 over y=x
Answer:
The average is around 75.5
Step-by-step explanation:
Answer:
3700hours
154days
Step-by-step explanation:
Speed can be defined as the distance cover per time, it can be expressed as
Speed= distance/ time........eqn(1)
Given:
distance between two planets= 4.07×10^¹²
speed of light = 1.1×10^⁹ kilometres per hour
Time= ??
Then substitute the values into equation (1) we have
Speed= distance/ time
1.1×10^⁹ kilometres per hour= 4.07×10^¹²kilometre/ time
Cross multiply, we have
Time= (4.07×10^¹²kilometre) /(1.1×10^⁹ kilometres per hour)
Time= 3700hours.
To convert to day, we know that
60 minute= 1hour
24hour=1day
Time= (3700hour×1day)/24hour
Time= 154days approximately.
Hence, the time taken for light to travel from one of these planets to the other is 154days or 3700hours
