Diana had a large stack of playing cards. She knew that 17 of them were kings. She took a sample of 30 cards and found 4 kings.

Mandarinka [93]

Answer:

Diana approximately had 128 cards

Step-by-step explanation:

Cross multiply:

$4n=17\cdot 30\\ \\4n=510\\ \\n=\dfrac{510}{4}=127.5\approx 128$

Me.Green tells you that a right Triangle has a hu triangle has a hypotenuse 13 and a leg of 5. She asks you to find the other le

tiny-mole [99]

the pythagorean theorem is a^2+b^2=c^2

You have a and c already, so its 5^2+b^2=13^2

13^2 equals 169. 5^2 equals 25.

You now have 25+b^2=169

169-25=144

The square root of 144 is 12.

The other leg is 12 units
