Answer:

9,216π or 28,938.2 meters³

Step-by-step explanation:

Given: diameter 48 inches

Radius 24 inches

Note:

Volume of hemisphere = volume of sphere / 2

Volume of hemisphere = 1/2 • 4/3 • πr³

= 1/2• 4/3×π×24³

= 1/2•18432π

= 9,216π

= 28,938.2 meters³

Total no of whole number of that have less than 1000 and divisble by 7

lbvjy [14]

Answer:

There are 142 whole numbers less than 1000 and divisible by 7.

Step-by-step explanation:

The multiples of 7 form an arithmetic sequence like shown:

7, 14, 21, ...

The last term of this sequence can be found by dividing 1000/7=142.9 and rounding down to the previous integer: 142*7= 994.

Thus, the sequence has:

a1=7, r=7, an=994. We need to find n and we'll do that by using the general term formula:

$a_n=a_1+(n-1).r$

And solving for n:

$\displaystyle n= \frac{a_n-a_1}{r}+1$

$\displaystyle n= \frac{994-7}{7}+1$

n = 142

There are 142 whole numbers less than 1000 and divisible by 7.

Paul makes green paint. The ratio of yellow to blue is 2:3. If he uses 1/5 ounce of yellow. How much blue should he use?

dybincka [34]

Answer:

A. 3/10

Step-by-step explanation:

So the ratio is saying 2 units to 3 units. What represents 1 unit when 1/5 is two units? We cut it in half which is 1/10.

Now we have 1 unit so we can easily find three by multiplying by three, or even just adding three together. So that's 3/10.

let me knowif you don't quite get it.

max2010maxim [7]

Answer:

$69

Step-by-step explanation:

Given

$Purchase = \$69$

$Amount\ Left = \$0$

Required

Determine the cash before purchase

To get the her amount before the purchase, we simply add both given parameters together.

This is done as follows;

$Amount = Amount Left + Purchase$

Substitute 0 for Amount Left and 60 for Purchase

$Amount = \$0 + \$69$

$Amount = \$69$

Hence, she had $69 before the purchase
