I NEED HELP PLEASE! Jenny's birthday cake is circular and has a 30 cm radius. Her slice creates an arc of with a central angle of 120 degrees. What is the area of Jenny's slice of cake? Give your answer in terms of pi. PLEASE HELP HELP HELP!!!!

Answers

When a circle (i.e. the cake) is cut through the radius, the parts formed are referred to as the sectors of the circle. The area of the slice in terms of $\pi$ is $300 \pi$

Given that

$r = 30cm$ --- the radius

$\theta = 120^o$ --- central angle

The area of the slice is calculated using the area of a sector, as follows:

$Area = (\theta)/(360) * \pi r^2$

So, we have:

$Area = (120)/(360) * \pi * 30^2$

$Area = (1)/(3) * \pi * 900$

$Area = \pi * 300$

$Area = 300\pi$

Hence, the area of the slice of cake is $300\pi$

Ok, so if the angle is 120 degrees, its one third of the full cake (which is 360 degrees). So the area of the whole circle (worked out with area = pi * r^2 where r is 30) gives 900*pi, and so one third of that (because her slice is one third) is 300pi.

revenue for the week is 2,000. Labor consits of two worker's. earning 8.00 per hour. who work 40 hours each. what is labor cost as a percentage of revenue.

Answers

so, two workers working 40 hours each, that's 80 hours of work. 8 dollars per hour in pay: 8*80=640; so 640 dollars were paid to the workers.

the labor cost is $(640)/(2000) *100$ =[tex] \frac{64}{2} /tex]=32

so the labor cost is 32% of the revenue.

A function is created to represent the amount of money in your checking account. What restrictions would be made to the domain?-The domain would include all real numbers.* -The domain would only include positive integers. -The domain would only include positive numbers. -The domain would only include integers. I am thinking that it could also be negative. Thank you for any and all help!

Answers

Answer:

B. The domain would only include positive integers.

C. The domain would only include positive numbers.

Step-by-step explanation:

We are given a function that represents the amount of money in the checking account.

As, the function contains the amount of money in the account, the domain cannot have negative values.

So, the domain cannot include all real numbers and it cannot include only integers.

Therefore, the domain can include positive numbers and therefore, it can also include positive integers.

Hence, B and C are correct.

Which one of the following numbers is a multiple of 8?A. 512
B. 98
C. 124
D. 27

Answers

A.512 because when you divide it by eight you get 64.

if you divide 512 by 8 you get 64 and 64 is a multiple of 8. so your answer is 512
