Let each side perpendicular to the river be "x".Then the side parallel to the river is "400-2x".
The formula for Area = width*length
A(x) = x(400-2x)
A(x) = 400x - 2x^2
You have a quadratic with a = -2 and b = 400
Maximum Area occurs where x = -b/2a = -400/(2*-2) = 100 ft. (width)
length = 400-2x = 400-2*100 = 200 ft (length)
Answer:
Probability [Randomly choose plant Juan's mother want] = 3 / 5
Step-by-step explanation:
Given:
Total number of plant in store = 30 plants
Number of plant kind Juan's mother want = 18
Find:
Probability [Randomly choose plant Juan's mother want]
Computation:
Probability of an event = Number of favorable outcome / Total number of outcomes
Probability [Randomly choose plant Juan's mother want] = Number of plant kind Juan's mother want / Total number of plant in store
Probability [Randomly choose plant Juan's mother want] = 18 / 30
Probability [Randomly choose plant Juan's mother want] = 3 / 5
15:20
divide each by 5
3:4
to find the ratio of the area's we square the ratio's of the sides
3^3 : 4^2
9:16
Choice B
Answer:
y-5=11
y-5+5=11+5 (Add 5 to both sides)
y=16 (Simplify)
I believe that y=16 cannot be simplified so y=16 should be the answer let me know if it helped.
Subtract 4 from both sides of the equation
you will end up with 2/7x=4
next multiply 7x by both sides
you will end up with 2=28x
next divide 28 from both sides
you will end up with x=1/14 in
fraction form. Hope this helps.
