36 ÷ 3 = 12
12 x 30 = 360 (mins)
The answer is that it would take you 360 minutes to ski a distance of 36 miles.
or you could say: t would take you 6 hours to ski a distance of 36 miles.
In this problem, you are asked to write a number in
scientific notation. In figures, 78 million would look like this:
78,000,000
To write this to scientific notation, you have to move the
decimal point to the left until you will get a number between 1 and 10.
Here, you will have to move the decimal point 7 times to get
7.8
The exponent of the scientific notation is the number of
times you moved your decimal point. Since the movement of decimal point is
going to the left, you will have a positive exponent.
The scientific notation would look like this:
7.8 x 10^7
Let Length = L
then
W=width = 2*L-18
Perimeter = 2(W+L)=2(2L-18+L)=36
divide by 2
3L-18=36/2=18
3L=18+18=36
L=36/3=12 => W=2*L-18=2*12-18=6
=>
Length = 12, Width=6
Check: 2(12+6)=2(18)=36 =perimeter ! checks!
Answer:
92
Step-by-step explanation:
you cant distribute unless there is parentheses
but if there is and you're just multiplying it would be
2112
Answer:
x = -77
Step-by-step explanation:
based on the given conditions
x - 14 = -91
x = -91 + 14 then calculate the difference between -91 - 14 = -77
thus x which is peters number = -77
