How many radians does the minute hand of a clock rotate through over half an hour? How many degrees?
Ivanshal [37]

Answer:

So minute hand will rotate \pi radian in half an hour

Step-by-step explanation:

In one hour minute hand of clock rotate about 360°

So in half an hour minute hand clock rotate \frac{360}{2}=180^{\circ}

We have to find how many minute hand rotate in radian

For conversion of degree to radian we have to multiply with \frac{\pi }{180}

So 180^{\circ}=180\times \frac{\pi}{180 }=\pi radian

So minute hand will rotate \pi radian in half an hour

The 8 students in Mrs. Alexander's class were asked how many minutes it takes them to get to school in the morning. Here is what
IrinaK [193]

To find the mean just add all of them then divide the result by 8. To find the median put the numbers in order. So 3, 3, 4, 4, 13, 15, 15, 16 then find the middle number, if there is not middle number (which there isn’t) add the two middle numbers (4 and 13) to get 17 then divide 17 by 2 to get 8.5 which is the median

Drag steps of the solution into order to solve for x in the equation 8(x+7)=104
Nadusha1986 [10]
Hello!

The first step to solving this equation would be to distribute the 8 to x+7 to simplify the equation:
(8*x)+(8*7)=104
8x+56=104

The second step would be to then subtract 56 from both sides to isolate 8x:
8x+56-56=104-56
8x=48

Finally, the last step would be to divide both sides by 8 to solve for x:
8x/8=48/8
x=6

Your final answer would be x=6

Hope this helps, and Happy New Year!

Angela weighs 15% less than she did one year ago. Which of the statements below is true?
Elden [556K]

The current weight W_c is 15% less than the weight Angela had 1 year ago (W). Or we can write,

W_c=(1-\frac{15}{100}) W\\ W_c=\frac{85}{100}W\\.

Thus Angela,s current weight is 85% of her weight one year ago.
