Answer:
The student took 2.5 minutes to paint 1 square foot.
Step-by-step explanation:
In order to know how long the student took to paint each square foot we first need to know the total area of the bulletin board. Since it is a rectangle we can compute it's area by multiplying the width and the height. That is:
area = 2*3 = 6 square foot
Since the student took 15 minutes to paint the whole board the pace at which he was working can be calculated by dividing the total area of the board by the time he took to paint all of it. So we have:
pace = 6/15 = 0.4 foot/min
To find how long it took him to paint 1 square foot we can divide it by the pace he was painting. We have:
time = 1/0.4 = 2.5 minutes
The student took 2.5 minutes to paint 1 square foot.
The radius of can is 2.524 inches
<em><u>Solution:</u></em>
Given that large can of tuna fish that has a volume of 66 cubic inches and a height of 3.3 inches
To find: Radius
Given a large can of tuna fish, we know that can is generally of cylinder shape, we can use the volume of cylinder formula,
<em><u>The volume of cylinder is given as:</u></em>

Where,
"r" is the radius of cylinder
"h" is the height of cylinder
is a constant equal to 3.14
Substituting the given values in above formula,

Thus the radius of can is 2.524 inches

</span>The distance poles B and E= BD+DE=4/5+7/10=(8+7)/10=15/10=3/2 yard
the answer is 3/2 yard (distance poles B and E)
