The fencing William chooses costs $29.53 per foot, including installation. What will the fencing cost? Show your work.

TiliK225 [7]

Answer:

$C = 29.53x$

Step-by-step explanation:

Given

$Unit\ cost = \$29.53$

Required

The cost of fencing (C)

The cost is calculated as:

$C = Unit\ Cost * Perimeter\ of fencing$

Let:

$x \to Perimeter\ of fencing$

So, we have:

$C = Unit\ Cost * x$

$C = 29.53 * x$

$C = 29.53x$

<em>The question cannot be solved further since the dimension of the fence is not given</em>

<em>If you know the dimension, calculate the fence perimeter and substitute the value for x</em>

Aricela is trying to estimate the distance between her house and the park. On a map with a scale of 0.5 in. = 2 miles, the dista

mrs_skeptik [129]

Answer:

Option A - $\frac{0.5}{2.75}=\frac{2}{d}$

Step-by-step explanation:

Given : Aricela is trying to estimate the distance between her house and the park. On a map with a scale of 0.5 in. = 2 miles, the distance between her house and the park is 2.75 in.

To find : Which proportion can Aricela use to determine the distance, d, between her house and the park?

Solution :

The distance between her house and the park is 'd' miles.

A scale of 0.5 in. = 2 miles

The distance between her house and the park is 2.75 in.

i.e. the scale is 2.75 in. = d miles

The proportion form is

$\frac{0.5\ in}{2.75\ in}=\frac{2\ miles}{d\ miles}$

Therefore, proportion can Aricela use to determine is $\frac{0.5}{2.75}=\frac{2}{d}$ .

So, option A is correct.

Answer:

x = 8, and y = 12

Step-by-step explanation:

There are 2 variables, so you need 2 equations to form a system of equations in two variables.

The upper left triangle has all angle measures given: 100, 2x + y, 5x + y. We know that the sum of the measures of the angles of a triangle is 180.

First equation:

100 + 2x + y + 5x + y = 180

Simplify:

7x + 2y = 80 (First equation)

Now we see that the upper and lower sides are parallel, so alternate interior angles are congruent. The angles measuring 2x + y and 5x - y are alternate interior angles and are congruent.

Second equation:

2x + y = 5x - y

Simplify:

3x - 2y = 0 (Second equation)

Now we use the first equation and the second equation as a system of simultaneous equations to solve for x and y.

7x + 2y = 80

3x - 2y = 0

Solve the second equation for 2x.

3x = 2y

Now replace 2y in the first equation with 3x.

7x + 3x = 80

10x = 80

x = 8

Replace x with 8 in the second equation.

3(8) - 2x = 0

24 = 2x

x = 12

Answer: x = 8, and y = 12

Answer:

y = -.075x +4.89

Step-by-step explanation:

The data set has almost no net slope, so the first equation is the most appropriate. (An absolute value function would be a much better fit.)

y = -.075x +4.89
