Answer:
37.5%
Step-by-step explanation:
40-x%*40=25
x%40=15
x%=15/40=37.5%
Answer:
the answer to this would be 256.
Step-by-step explanation:
before explaining this,
- negative x negative = positive
- positive x positive = positive
- negative x positive = negative
- positive x negative = negative
this would be because -2 x -2 it equals 4. then, we multiply 4 x -2 and we get -8, then we multiply -8 x -2 and we get 16, then we keep doing the same thing until we get the answer/ used all the -2's.
1. -2 x -2 = 4
2. 4 x -2 = -8
3. -8 x -2 = 16
4. 16 x -2 = -32
5. -32 x -2 = 64
6. 64 x -2 = -128
7. -128 x -2 = 256
2+2+2x6795-90+6000x5678910+5-1x67^8
The number of hours Tom took a trip of 1,020 miles is 3 hours.
Given that, Tom took a trip of 1,020 miles.
The speedformula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance traveled by a body in a given period of time. The SI unit of speed is m/s.
Tom traveled by train at 55 miles an hour and the same number of hours by plane at 285 mph.
Let the number of miles travelled by train be x. Then, the number of miles travelled by plane be 1020-x.
Time = x/55 = (1020-x)/285
⇒ 285x = 55 (1020-x)
⇒ 285x = 56100 - 55x
⇒ 285x + 55x = 56100
⇒ 340x= 56100
⇒ x = 56100/340
⇒ x = 165 miles
So, time = 165/55 = 3 hours
Therefore, the number of hours Tom took a trip of 1,020 miles is 3 hours.
