Hi,

Formula for ball volume (considered a sphera) is:

$V=\dfrac{4\pi\cdot r^3}3=\dfrac{4\pi\cdot 15^3}3=\dfrac{42,390}3=14,130\ in^3.$

Ali Clara and Shane raise money for new books for the school library all Ellie rays 20% more than Clara and $58 more than Shan C

Vikki [24]

Answer:

a. $435

b. 33.33%

Step-by-step explanation:

P.S - The exact question is -

Let Clara raised money = x

As given,

Ali raised 20% more than Clara

⇒Ali raised money = $x + \frac{20}{100}x = x + \frac{1}{5} x = \frac{6}{5}x$

Also given,

Clara raised $\frac{1}{4}$ times more than Shan

Clara raised money = Shan raise money + $\frac{1}{4}$ times shan raired money

⇒Clara raised money = $\frac{5}{4}$ Shan raised money

⇒Shan raised money = $\frac{4}{5}$ times Clara

⇒Shan raised money = $\frac{4}{5}$ x

As given,

Ali raised $58 more than shan

⇒ $\frac{6}{5}x = \frac{4}{5}x + 58$

⇒ $\frac{6}{5}x -\frac{4}{5} x = 58$

⇒ $\frac{2}{5}x = 58$

⇒x = (29)(5) = $145

∴ we get

Clara raised money = x = $145

Ali raised money = $\frac{6}{5}x$ = $174

Shan raised money = $\frac{4}{5}$ x = $116

a.)

Total raised money = $145 + 174 + 116 = $435

b.)

Percentage of money Clara raised = $\frac{145}{435}$ ×100% = $\frac{1}{3}$ ×100% = 33.33%

Find the missing value so that the two points have a slope of -3/10 (x,-8) and (-5,-5)

rosijanka [135]

Answer:

Step-by-step explanation:

The slope is given by

m = (y2-y1)/(x2-x1)

-3/10 = (-5--8)/(-5-x)

-3/10 = (-5+8)/(-5-x)

Using cross multiplication

-3 (-5-x) = 10*(-5+8)

Simplify

-3(-5-x) =10(3)

Divide by -3

-3/-3(-5-x) =10(3)/-3

-5-x = -10

Add 5 to each side

-5-x+5 = -10+5

-x=-5

Divide by -1

x=5

Katyanochek1 [597]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

Please find the complete question in the attached file.

$Box \ average =\frac{1}{6} \\\\SD = \frac{1}{6} \times \frac{5}{6} = \frac{5}{36} \approx 0.373\\\\Expected \ value= 1000 \times \frac{1}{6} \approx 166.7\\\\SE = 1000 \times 0.373 \approx 11.8\\\\$

The total number of aces is approximately 167, 12 or more. The SE is 12 out of 1000, which is 1.2 percent.

The percentage of aces is expected to be around 16.67% , or 1.2%.
