Find the dimensions of the regular corral split into 2 pens of the same size producing the greatest possible enclosed area given
mrs_skeptik [129]

Answer:

Length = 225 ft

Width = 150 ft

Step-by-step explanation:

If L is the length and W is the width, then:

900 = 2L + 3W

A = LW

Solve for W in the first equation:

3W = 900 − 2L

W = 300 − ⅔ L

Substitute into the area equation:

A = L (300 − ⅔ L)

A = 300L − ⅔ L²

Use calculus to find dA/dL and set to 0, or use the formula for vertex of a parabola.

Using calculus:

dA/dL = 300 − 4/3 L

0 = 300 − 4/3 L

L = 225

Using vertex formula:

L = -b / (2a)

L = -300 / (-4/3)

L = 225

Find the width:

W = 300 − ⅔ L

W = 150

You got the right answers, but the problem says to assume that the length is greater than the width.

Samuel is running a 3-mile race. He would like to finish the race in under 33 minutes. He has already run for 10. 5 minutes. The
photoshop1234 [79]

x < 22.5; Samuel has less than 22.5 minutes to finish the race in the estimated time.

<h3>What amount of time Samuel left for the race?</h3>

The given inequality is-

10x < 33

From here, we define the variable x.

x = Number of the minutes left for the race

From here we can find the value of x

We have then:

x < 33-10.5

x < 22.5

Hence, Samuel has less than 22.5 minutes to finish the race in the estimated time.

if a bag contains 400 coins,and 33 1 over 2 are nickels, how many nickels are there what percent of the coins are not nickels
iren2701 [21]
Assuming the number is 331/2, or 331 over 2: 
331/2 = 165.5 ÷ 400 = .4138 x 100% = 41.38%
100% - 41.38% = 58.62% not nickels

If the number is 33 1/2, or 33 and one half
33 1/2 = 67.5 ÷ 400 = 0.0838 x 100% = 8.38%
100% - 8.38% = 91.62% not nickels
