Write an equation and solve it. Call the length of the shorter piece "x", in this case, the longer piece is "3x". The sum of the two is equal to 116 inches.
Answer:
The answer for the number after 400 is <u>1595</u><u>.</u>
Step-by-step explanation:
:)
9 gallons of water
Divide the gallons by the number of plants.
6 ÷ 20 = 0.3
Multiply that by the number of plants you want.
0.3 x 30 = 9
Answer:
Some k's that will work:
1/2
1/3
1/4
(There are infinitely many answers.)
Step-by-step explanation:
Obviously 5 won't work because 25<5 is not true.
What about a negative? -5?
25<-5 is not true.
How about 1/3? 1/9<1/3 is true so 1/3 works.
Note: Think of a number between 0 and 1.
1/4<1/2 is true and (1/2)^2=1/4.
1/16<1/4 is true and (1/4)^2=1/16.
You can solve k^2<k.
Subtract k on both sides.
k^2-k<0
Factor.
k(k-1)<0.
So k^2-k is a parabola with x-intercepts (k-intercepts) at k=0 and k=1.
The parabola is open up so any number between 0 and 1 will satisfy k^2<k since between 0 and 1 the parabola is less than y=0 ( the x-axis).
