Vonna scored 35 goals at soccer practice. Her ratio of goals to misses was 5:8. How many times did she miss?
Digiron [165]

<u>Answer:</u> She misses 56 times at a soccer practice.

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

Let the goals she misses be 'x'.

According to the question:

5:8::35:x

These two ratios follow direct relationship, so:

\frac{5}{8}=\frac{35}{x}\\\\5x=35\times 8\\\\x=\frac{280}{5}\\\\x=56

Hence, Vonna misses 56 times at a soccer practice.

What's the answer?????????????
Taya2010 [7]

Answer:

BD = 12 :)

Step-by-step explanation:

Alright, we'll need the Pythagorean theorem for this!

So, the length of AC is 10. That means the lengths of AD and DC are both half of that, which is 5 :)

DC = 5

We already know that BC = 13, so we can plug in these values into the pythagorean theorem for the right triangle BDC:

BD^2 + DC^2 = BC^2

BD^2 + 5^2 = 13^2

BD^2 + 25 = 169

BD^2 = 169 - 25 = 144

BD = √144 = 12 :)

Volume of box with side length of 5 = 5^3 = 125

Volume of sphere = (4/3)*pi*5^3 = (4/3)pi * 125

Ratio = 125/(4pi/3)*125  = 1/(4pi/3) = 3/(4pi)
