Answer:
Mr.Kim is presently 40 years old, and his daughter is 15 years old.
Step-by-step explanation:
K is Mr Kim's present age
D=his daughter's present age.
K=D+25 ; or Mr.Kim is his daughter's age plus 25 years.
K+10=2(D+10); or in 10 years, Mr Kim will be twice daughters age
Substitute the K from the first equation into the second equation and then solve for variable D.
(D+25)+10 = 2(D+10) Simplify.
D+35 = 2D+20 You must subtract D from both sides.
35 = D+20 Lastly, subtract 20 from both sides.
15 = D or D = 15
Mr Kim's daughter's is 15 years old.
Mr Kim's age is D+25
15+25 = 40 years old.
Answer:
Missing number is 8
Step-by-step explanation:
Expression: <span>t=2(2h/32)^1/2
Squaring on both sides,
t</span>² = 2(2h/32)
t² = 4h/32
t² = h/8
h = 8t²
Height of player 1 = 8(0.9)² = 6.48 Feet
Height of player 2 = 8(0.8)² = 5.12 Feet
Difference = 6.48 - 5.12= 1.36 Feet = 16.32 in
In short, Your Answer would be:16 Inches
Hope this helps!
