Answer:
MK
Step-by-step explanation:
ML is the short side of right triangle MLK. MJ is the hypotenuse of right triangle MKJ. This gives you a clue that the ratios of interest are the short side to the hypotenuse. All these right triangles are similar, so ...
ML/MK = MK/MJ . . . . . ratio of short side to hypotenuse is the same
ML·MJ = MK² . . . . . . . cross multiply
MK = √(ML·MJ) . . . . . the geometric mean of ML and MJ is MK
50 secs
as $90÷5hrs= 18 $ per hrs
$18÷60min=$0.30 per min
$0.30÷60sec=$0.005 per sec
$0.25÷$0.005= 50sec to make $0.25
so 50sec is the answer
The student Government wants to make a profit of at least $3000 from a magazines sales. At least $3000 simply means the profit should be $3000 and above.
There profit is $1.25 per magazine(m) subscription sold.
Their expenses are as follows
advertisement in school = $100
advertisement in community = $150
let
m = number of magazine sold
profit = selling price - cost price
selling price

Cost price

Therefore,
The answer to your question is 35
Set up a proportion.
(8.75/5)=(x/2)
5x=2*8.75
5x = 17.5
x= 3.5
