Answer:
I need more info but if your wondering how much each notebook cost the answer is
Step-by-step explanation:
So first we have to divide 28/8 beacuse thats how many over how much.
When we do it it becomes 3.5. Now this is our number but we must add a zero to the end, so now it $3.50. $3.50 for each notebook!
Hope this helps you, :3
Please consiter <3 me it helps me out a lot!
At the start you will start with $7 and $7.60 there is a simple way and a more complex process. The simple way is using the formula of y=mx+b so y=.8x+7 and the other way is just too add .8 to 7 and .7 to 7.6 and keep doing that till you get the answer. The answer is 7, seven topping have to be added to make them the same price.
Answer:
15 centimeters.
Step-by-step explanation:
We must calculate the volume of each cylinder and add it, like this:
v = pi * (r ^ 2) * l
replacing:
v1 = 3.14 * (5 ^ 2) * 7
v1 = 549.5
v2 = 3.14 * (10 ^ 2) * 5
v2 = 1570
The sum would be:
549.5 + 1570 = 2119.5
That would be the volume of the cylindrical disk, this case would be the same formula only that it would not be length but thickness, like this:
v = pi * (r ^ 2) * t
we want to know r, therefore:
r ^ 2 = v / pi * t
replacing:
r ^ 2 = 2119.5 / (3.14 * 3)
r ^ 2 = 225
r = 15
which means that the radius would be 15 centimeters.
