You are a landscaper, and you are designing a fence to enclose part of a yard. The section to be enclosed is rectangular and has a width of 21 feet and a length of 38 feet. What length of fence, in feet, will you need to enclose this part of the yard? 59 60 118 120 798

Answers

Answer:

If you draw this out, you can see that total fence equation will be:

2L + 4W = 1200

Simplify, divide by 2

L + 2W = 600

L = (600-2W)

:

Area;

A = L*W

Substitute (600-2W) for L:

A = (600-2W)*W

A = -2W^2 + 600W; a quadratic equation

 

:

The dimension that will produce the greatest area will be the "axis of symmetry

which is: x = %28-b%29%2F%282a%29

:

In this equation a=-2, b=600

W = %28-600%29%2F%282%2A-2%29

W = %28-600%29%2F%28-4%29

W = +150 ft is the width

:

Find the length

L = 600 - 2(150)

L = 300 ft is the length

:

We can say the a field 300 by 150 gives he greatest area

:

This illustrated on a graph where y axis is the area and x axis is the width:

In that case you now know. The answer to the first blank (coefficient of x)
To find the y intercept (the second blank), which I will call c, you can use either pair of the coordinates and substitute them in the equation together with the gradient you found previously.
If you choose to sub in (0,6) and since gradient=0.5,
Then: 6=0.5(0) + c
therefore, c=6
Likewise, if you choose to sub in (8,10)
Then: 10=0.5(8) + c
Therefore, c also equals to 6
So in conclusion the gradient of the slop is 0.5 and the y intercept is 6
The linear function will be: y=0.5x + 6

What is the greatest common factor of 60,70, and 80

Answers

Answer:

10

Step-by-step explanation:

Answer: The GCF of 60, 70, and 80 is 10.

Step-by-step explanation: If you think about it, the GCF is definitaly going to be 10. That is because you can multiply 10 to get 60, 70, and 80. There is no other number higher than 10 that can be multiplied by something to get all of these values.  

If x=4 y=-3 and z =5 find the value of 5y +2x-z

Answers

The answer is -12.

All you have to do is substitute the variables for their values and solve.

Hope this helps!

Answer:-12

Step-by-step explanation:

So if the equation is 5y+2x-z and the substitutions are x=4     y=-3      z=5 , all you have to do is replace each variable with its given numbers. Like so

5(-3)+2(4)-5

Now what you have to do is simplify

Negative times a positive is a negative

Negative times a negative is a positive

Positive times a positive is a positive

So....

-15+8-5

-20+8

-12

This is a simple substitution problem. Remember the basics of negatives and positives! Than you will be just fine! :D

Graph 8x−4y=16. From Big Ideas Math

Answers

Solve for y.

8x−4y=16

-4y = -8x + 16

y = (-8x + 16)/-4

y = (-8x)/-4 + (16/-4)

y = 2x - 4

We only need two points to graph linear equations.

Now let x be 0 and solve for y.

y = 2(0) - 4

y = -4

This leads to the point (0, -4).

We need another point.

Let y = 0 and solve for x.

0 = 2x - 4

4 = 2x

4/2 = x

2 = x

This leads to the point (2,0).

Plot these two points on the xy-plane and connect the points with a straight line.

I'll let you do that.

what is the answer to this? −1.2b−5.3≥1.9

Answers

Answer:

b≤−6

here u go

Answer:

b ≤ -6 ✅

Step-by-step explanation:

To solve an inequality, we will solve just like a normal equation. The goal is to isolate b, so we can determine the set of values it can take on.

Step 1: Add 5.3

We need to reverse the operation - 5.3, so we add 5.3.

-1.2b - 5.3 + 5.3 ≥ 1.9 + 5.3

-1.2b ≥ 7.2

Step 2: Divide by -1.2

We need to reverse the multiplication that is multiplying b by -1.2, so we will divide. However, we must remember an important rule first.

Important: When we divide by a negative number in an inequality, we must reverse the inequality sign, so ≥ becomes ≤.

-1.2b / -1.2 ≥ 7.2 / -1.2

b ≤ -6 (remember to reverse the sign!)

Step 3: Check

We now substitute our answer in and see if it is correct. We will use a number that is smaller than -6, for example, -8.

-1.2(-8) - 5.3 ≥ 1.9

9.6 - 5.3 ≥ 1.9

4.3 ≥ 1.9 ✅

We can check again with -6, since this and all numbers smaller than it should be a solution set.

-1.2(-6) - 5.3 ≥ 1.9

7.2 - 5.3 ≥ 1.9

1.9 ≥ 1.9 ✅

b ≤ -6 ✅

You want to know the opinions of drivers with valid licenses across America on the issue of establishing a law that requires individuals to take and pass another driver's test at the age of 65 to determine whether they may retain their license. You obtain a list of all licensed drivers and mail a survey to a random sample of 10,000 drivers. Of those, 6,457 responded and 46% say they favor the test. Which of the following statements is true? (5 points)

A. Because random sampling is used, we can feel confident that the percentage of all
drivers with a valid license who say they favor the test is close to 46%.
B. The results of this survey may be affected by nonresponse bias.
C. We cannot trust these results because the survey was mailed. Only survey results
from face-to-face interviews are considered valid.
D. Because more than half of those who were mailed the survey actually responded,
we can feel fairly confident that the actual percentage of all drivers with a valid
license who say they favor another test is close to 46%.
