A baseball has a diameter of 6 cm. If you wanted to replace the inside of the baseball with air, how much would be needed in cub

e-lub [12.9K]

This is just another way of asking "what is the volume of a sphere of 6cm"
The volume of a sphere is $V= \frac{3}{4} \pi R^{3}$
The R is 3cm in this problem since the diameter is twice the radius. For a 3cm radius sphere this is 113.1cm^3

Solve the system using the substituiton method<br> branliest offered<br> 3x-7y=10<br> x-4y=5

fiasKO [112]

Hi there!

To solve this problem using substitution, we need to set x equal to a value and substitute it into the other equation.

Since
x - 4y = 5,
x = 5 + 4y

3x - 7y = 10
3(5 + 4y) - 7y = 10
15 + 12y - 7y = 10
15 + 5y = 10
5y = -5
y = -1

Now that we know y is -1, we can substitute it back into the equation to find x:

y = -1
x - 4y = 5
x - 4(-1) = 5
x - (-4) = 5
x + 4 = 5
x = 1

So, your answers are x = 1 and y = -1.

Hope this helps!

If the simple interest on $4000 for 8 years is $2240, then what is the interest rate?

mixer [17]

$~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\dotfill & \$2240\\ P=\textit{original amount deposited}\dotfill & \$4000\\ r=rate\to r\%\to \frac{r}{100}\\ t=years\dotfill &8 \end{cases} \\\\\\ 2240 = (4000)(\frac{r}{100})(8) \implies 2240=\cfrac{32000r}{100}\implies 2240=320r \\\\\\ \cfrac{2240}{320}=r\implies 7=r$
