Brandon is 24 michael is 72...hope that helps :D
This question requires you to know the lowest common multiple (LCM) of 5, 4 and 2. there are a few ways to do that. in this case the LCM would be 20. this means that in 20 year the science department would buy all 3 equipment at the same time
the question does not present the options, but this
does not interfere with the resolution
Let
x------> the length of the swimming pool
y------> the width of the swimming pool
we know that
x=12 ft
y=12-t
the distance between Mike and Ryan is equal to the distance of the diagonal of the rectangular swimming pool
D is the diagonal
D=32 ft-----> D²=32²----> equation 1
D²=x²+y²---> D²=12²+(12-t)²-----> equation 2
equate equation 1 and equation 2
32²=12²+(12-t)²------> 1024=144+(144-24t+t²)
t²-24t-736=0-----> this equation can be used to calculate the values of t
the answer is
the equation t²-24t-736=0
can be used to calculate the values of t
Answer:
He has $36 Left
Step-by-step explanation:
Multiply 5/8 and 120
75 (Money spent)
120 - 75 = 45
45 (Money Left)
Multiply 1/5 and 45
9 (Money Spent)
45 -9= 36
He has $36 Left
