Robert says he needs 250 plastic sleevs for his basball card collection.He has 3084 baseball cards.Each sleev holds 12 cards do

Iteru [2.4K]

Answer:

Step-by-step explanation:

Given that:

Plastic sleeves needed = 250

Number of baseball cards = 3084

Sleeves held per card = 12

To determine the number of sleeves needed ;

Number of baseball cards / number of sleeves per card

= 3084 / 12

= 257

No, I do not agree with Roberts, from the calculation above, the number of plastic sleeves needed is 257

The volume of a cone-shaped funnel is 236 cubic centimeters. The radius of the funnel is 5 centimeters Find the height of the fu

DochEvi [55]

Answer:

9 cm

Step-by-step explanation:

V = 1/3 pi r^2 h

V = 1/3 * 3.14 * 5^2 * h

236 = 1/3 * 3.14 * 25 * h

236 = 26.1667 h

236 / 26.1667 = h

9.019 = h

Rounded to the nearest whole number the h is about 9 cm.

Can someone answer this question?

KonstantinChe [14]

Answer:

No solution.

Step-by-step explanation:

(1/12)^-2b * 12^(-2b + 2) = 12

1/12 is basically the same thing as 12^-1.

12^(-1 * -2b) * 12^(-2b + 2) = 12

12^2b * 12^(-2b + 2) = 12

12^(2b - 2b + 2) = 12

12^2 = 12

Since the answers don't match up, the answer will be no solution.

Hope this helps!

Sophie has to choose seven different positive (non zero) whole numbers whose mean is 7.

Anna71 [15]

Answer:

The largest possible number is 28.

Step-by-step explanation:

Sophie has to choose seven different numbers whose mean is 7, this means that the sum of the numbers is 49. (since the mean is the sum of them all divided by 7 and if we want the mean to be 7, then the sum would need to be 49).

We are asked what is the largest possible number she could choose, so therefore, the other six numbers should be non-zero and the smallest ones so she would have to choose the numbers from 1 to 6 first.

Let's see how much they sum up: $1+2+3+4+5+6=21$

So now, she needs one more number to sum up to 21 and that will give her 49 in total, this number is 28 (since 28 + 21 =49).

Thus, 28 is the largest number she could choose because if she chose any other greater number the mean would be bigger than 49.
