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

Answers

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 (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 (\pi )/(180)

So 180^(\circ)=180* (\pi)/(180 )=\pi radian

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

The length and width of a rectangle have a sum of 90. What dimensions give the maximum area?

Answers

w-width\nl-length\n\n2w+2l=90\n2l=90-2w\ \ \ \ /:2\nl=45-w\n\nA=wl\to A=w(45-w)=45w-w^2

Area\ of\ a\ rectangle\ is\ a\ square\ function.\nThe\ maximum\ area\ is\ equal\ to\ the\ y-coordinate\ of\ vertex\nand\
2( l + w) = 90, where l, w are dimensions of the rectangle => l + w = 45;
The maximum area is obtain when l = w;
Then l = w = 45/2 = 22.5

Identify the percent of change as an increase or decrease. Then find the percent of change, rounding to the nearest tenth of a percent, if necessary.60 cars to 24 cars

Answers

Answer:

-60% decrease

Step-by-step explanation:

60 is the old value and 24 is the new value.

percent change = (new - old)/(|old|) x 100%

so for this problem, you can substitute the values given in the formula:

percent change = (60-24)/(|60|) x 100% = (-36)/(60) x 100% =

-60% (decrease)

To find the mass in grams, multiply the number of kilograms by the unit rate, 1,000 grams per kilogram.

Explanation: To find the mass in grams, you multiply the number of kilograms by the unit rate, which is 1,000 grams per kilogram. So, to convert 12 kilograms to grams, you would multiply 12 by 1,000. The mass of the package in grams would be 12,000 grams.
