Answer:
Wheel1 = 147inches , wheel 2 = 113inches
Wheel 1 will travel 147 revolutions.
Step-by-step explanation:
Finding the circumference of both wheels
Wheel 1 = 2 pi r = 2 × 3.142 × 23.4 = 147.05 inches. To the nearest inches = 147inches
Wheel 2 = 2 pi × r = 2 × 3.142 × 18 = 113.11inches . To the nearest inches = 113inches.
I rotation = 1 revolution
In 1 rotation, wheel 1 will travel= 147 × 1 = 147 revolutions.
The answer is : (3x-1)(x+4)
Answer:
Average speed = 9.91 m/s
Explanation :
Total distance covered by a runner = 200 m
Time taken to complete this distance = 20.19 sec
We need to find the average of runner speed in meter/sec
We use the speed, distance, time formula
![speed = \frac{distance}{time}](https://tex.z-dn.net/?f=speed%20%3D%20%5Cfrac%7Bdistance%7D%7Btime%7D)
speed = ![\frac{200}{20.19}](https://tex.z-dn.net/?f=%5Cfrac%7B200%7D%7B20.19%7D)
Average speed = 9.91 m/s
that's the final answer.
I hope it will help you.
Answer:
1%
Step-by-step explanation:
S.P of each radio=$ 2288
Total S.P=
$4576
Gain=10%
Lose=10%
C.P=![\frac{S.P\times 100}{100+gain(in\;percent)}](https://tex.z-dn.net/?f=%5Cfrac%7BS.P%5Ctimes%20100%7D%7B100%2Bgain%28in%5C%3Bpercent%29%7D)
C.P=![\frac{S.P\times 100}{100-loss(in\;percent)}](https://tex.z-dn.net/?f=%5Cfrac%7BS.P%5Ctimes%20100%7D%7B100-loss%28in%5C%3Bpercent%29%7D)
By using the formula
C.P of one radio=
$2080
C.P of another radio=
=$2542.2
Total C.P of two radios=2080+2542.2=$4622.2
Total C.P >Total S.P
Loss=S.P-C.P
Loss=4622.2-4576=$46.2
Loss%=![\frac{Loss}{C.P}\times 100](https://tex.z-dn.net/?f=%5Cfrac%7BLoss%7D%7BC.P%7D%5Ctimes%20100)
Loss %=
1%
Hence, his loss 1%
