Hey there!!
Given :

Find f ( 7.5 )
Now, we will need to substitute the value of 7.5 in place of x



Hope my answer helps!
Answer:
The answer is 0.005.
Step-by-step explanation:
<u>When you divide any number by 10, you move the decimal point over to the left by </u>1 place.
If, for example, you were instead multiplying by 10, your answer would change to 0.5.
Answer:
31
Step-by-step explanation:
50 x .62= 31
(games played) x the percentage won.
You could muliply 50 by 62% if your calculator has the % symbol if not you have to turn it into a decimal. To go from percent to decimal just take your percentage and move the decimal to the left twice. 62% = .62

Answer:
x = 16
Step-by-step explanation:
Either or both of the right triangles can be used to find x. Or, triangle ABC could be used. All numbers are assumed to be degrees.
<u>Using ∆ABD</u>
55 +90 +2x+3 = 180
2x = 32 . . . . . . subtract 148
x = 16
<u>Using ∆BCD</u>
50 +90 +2x+8 = 180
2x = 32 . . . . . . subtract 148
x = 16
<u>Using ∆ABC</u>
55 +(2x +3) +50 +(2x +8) = 180
4x = 64 . . . . . . . subtract 116
x = 16
