A storage tank holds 235,500 in^3 of a chemical. The chemical is dispensed to completely fill 25 identical cylindrical container

ololo11 [35]

Volume of a cylinder is given by V = πr^2h

Since the content of the storage tank completely filled the 25 identical cylinders, this means that the volume of the 25 cylinders combined is equal to the volume of the storage tank.

25(πr^2h) = 235,500
πr^2h = 235,500/25 = 9,420
h = 9,420/(3.14 x 5^2) = 9,420/78.5 = 120.

Therefore, the height of the cylinderical containers is 120 in

12. An equation is shown. 8 1/2 - 3 1/? = 5 3/12<br>What is the value of the missing number?

weeeeeb [17]

Answer:

Step-by-step explanation:

Alright, lets get started.

$8\frac{1}{2}-3\frac{1}{?}=5\frac{3}{12}$

These are mixed number given.

Suppose the complete mixed number of second place is x.

Converting mixed numbers into fractions.

$\frac{17}{2}-x=\frac{63}{12}$

Adding x in both sides

$\frac{17}{2}=x+\frac{63}{12}$

$x=\frac{17}{2}-\frac{63}{12}$

Making common denominator

$x=\frac{102}{12}-\frac{63}{12}$

$x=\frac{39}{12}$

$x=\frac{13}{4}$

In mixed number form:

$x=3\frac{1}{4}$

So comparing with given equation, the '?' sign will be equal to 4.

Hence the answer is 4 : Answer

Hope it will help :)

Tommy has 6 more than 3 times the amount of money in his bank account than Judy. Judy has $7500 more than a number in her accoun

Ad libitum [116K]

Answer:

Amount of money Judy has in her account is $\$(7500+n)$ .

Amount of money Tommy has in his account is $\$(22506+3n)$

Step-by-step explanation:

To find : Amount of money in Judy account and amount of money in Tommy account:

Solution:

Given:

Judy has $7500 more than a number in her account.

Let the number be 'n'.

So we can say that;

Amount of money in Judy account is equal to 7500 plus number.

framing in equation form we get;

Amount of money in Judy account = $\$(7500+n)$

Hence Amount of money Judy has in her account is $\$(7500+n)$ .

Now Given:

Tommy has 6 more than 3 times the amount of money in his bank account than Judy.

So we can say that;

Amount of money in Tommy account is equal to 3 multiplied by Amount of money in Judy account plus 6.

framing in equation form we get;

Amount of money in Tommy account = $3(7500+n)+6 =22500+3n+6=\$(22506+3n)$

Hence Amount of money Tommy has in his account is $\$(22506+3n)$ .
