Answer:
Expressing a number in a power of 2 means that you have to figure out how many times you should multiply 2 by itself so the product will be that number.
The number is expressed as 2^n
For example:
Express 16 as a power of 2:
To get 16, you have to multiply 2 by 4 times.
2 × 2 × 2 × 2 = 16
16 = 2^4
Then the answer is 2^4
117/3 = 39
39 + 39 + 39 = 177
They must be consecutive.
The integers are 37, 39, and 41.
Answer: D. 136in^2
Step-by-step explanation:
Find the surface area if all sides and add
4*10=40
2*4=8
2*4=8
4*10=40
2*10=20
2*10=20
40+40+8+8+20+20=136
136in^2
You find the rates of each computer on its own...
One does the job in 55 minutes which we can say is 1/55
The other has a rate of 1/45.
The question wants to know how long it would take both working simultaneously to complete the job...
t/55+t/45=1
(9t+11t)/495=1
20t=495
t=24.75 minutes (24:15)
