Dami works 4 times as many hours per week as Cooler. Together they work a total of 49 h One week. Find the number of hours worked by each person

Cooler - 9.8 hours   |   Dami - 39.2 hours

Step-by-step explanation:

If Dami works 4 times as much as Cooler, and Cooler works x hours every week, then Dami works 4*x hours every week, or 4x. Since the combined time they work is 49 hours, we can represent this in the equation 4x+x=49, or 5x=49. Dividing both sides by 5 we get x=9.8.

Since Cooler works x hours every week, he worked for 9.8 hours. And since Dami works 4x hours every week, she worked 4*9.8 hours=39.2 hours.

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

c is the answer
