Answer:

B. 733 customers

Step-by-step explanation:

15+30+45=90

since 30 people select a black frame, 1/3 of the customers picked black frames. If this data is consistent through the month (which we have to assume it is) then that means 1/3 of customers select a black frame on average. 1/3 of 2,200 is about 733, so we can assume, using the data given, that about 733 customers selected black frames! :)

And the cross-section perpendicular to the yaxis is a square. Set up a definite integral expressing the volume of the solid
zheka24 [161]

The volume of the cross-section perpendicular to the solid is the amount of space in the cross-section

<h3>How to set up the integral?</h3>

The question is incomplete;

So, I will give a general explanation on how to set up a definite integral for volume of a solid

Assume the solid is a cone;

Using the disk method, the integral of the volume is:

V = \int\limits^a_b {\pi r(x)^2} \, dx

Using the washer method, the integral of the volume is:

V = \int\limits^a_b {\pi [R(x)^2 -r(x)^2 ]} \, dx

1/10+50/100 need help ​
monitta

Answer:

3/5

Step-by-step explanation:

For this problem, you first have to make the denominators the same. You can use 100 in this example. You will have to multiply 1/10*10 which gives you 10/100. Then you add the numerator and denominator which is 60/100. Then you simplify to give you the answer of 3/5. I hope this helps you!
