Answer:
The last one: 70/100 = x/80
And 56 free throws.
Explanation:
70% is 70 out of 100. And if the player is free throwing a total of 80 times, then 80 is 100% of the free throws. Both of the values that represent 100% are the denominators in the fractions.
The equations are equal, and whatever you do to the bottom, you have to do to the top. 100 was multiplied by 4/5 to get 80. So 70 is multiplied by 4/5 to get x.
4/5 * 70 is 56
<u>Examining the question:</u>
We are given the expression:
We know from Basic trigonometry that:
<u>Simplifying the expression:</u>
Replacing these values in the given expression, we get:
Since the denominator of both the values in the denominator is the same:
We know that =
, using the same property:
and we are done!
