A cylindrical can contains an unknown number of golf balls. The can has a height of 10 inches and a volume of 15.625 Pi inches c

AlladinOne [14]

20 golf balls can fit in the can.

<u>Step-by-step explanation:</u>

Given:

Height (h) = 10 Inches

Volume of 15.625 Pi inches cube.

To Find:

How many balls can be filled in that can.

Solution:

Diameter of the golf ball [as per standard value] = 1.68 in

Radius of the golf ball = $\frac{1.68}{2} = 0.84 in$

Volume of the golf ball = $\frac{4\pi r^3}{3}$

= $\frac{4\pi (0.84)^3}{3}$

= $2.5 (or) 0.79 \pi inches$

Volume of the can = $15.625\pi in^3$

Now we have to divide the volume of the can by the volume of the golf ball, we will get = $\frac{15.625 \pi }{0.79\pi } = 19.7$ balls

Thus we can conclude that approximately 20 balls can be filled in that can.

Which list contains values that are all part of the solution set of the graphed inequality? 2, 1, 3. 9, 4 2001. 3, 4, 0, 2. 6 1.

olya-2409 [2.1K]

The inequality is,

$0\leq x\leq 2001.3$

we have given that the solution set

2, 1, 3. 9, 4 2001. 3, 4, 0, 2. 6 1. 1, 1. 5, 19. 7, 8. 2 11, 1, 48. 5, 7.

here we have given that all the values of x are positive and

Which is the smallest point in above set?

0

and

Which is the highest point in the above set?

2001.3

Therefore,

we have a=0 and b=2001.2

Our equality lie in a and b

Therefore,

$a\leq x\leq b$

Plug the value of a and b we get

$0\leq x\leq 2001.3$

Therefore we get the inequality is,

$0\leq x\leq 2001.3$

Using the standard 28/36 guidelines, what is the maximum mortgage payment allowed for someone with an annual salary of $60,750?

Anna11 [10]

$\frac{28}{36}$ rule says that 28 % of your total income should be spent on Housing finances and 36 % of your gross total income should be spend for Debts.

Annual Salary = $ 60,750

Maximum mortgage payment=28% of $ 60,750

$=\frac{28}{100} \times 60750=\frac{1701,00}{100}\\\\ =1701$

Maximum ,mortgage payment allowed for someone with an annual salary of $60,750= $ 1,701.00→→→Option (C)

If the sum of the measure of two angles in a triangle is 101, then the measure

LiRa [457]

Answer:

79 degrees.

Step-by-step explanation:

It is just a rule of trigonometry that all the angles inside ANY triangle will add up to 180 degrees.

There's only 3 possible angles in a triangle, so if you know what the sum of 2 are, its easy to find the last one.

All you have to do is 180 - 101, which equals 79 degrees.

Hope this helped : )
