Answer:

210 feet

Step-by-step explanation:

First, you have to use the measurements of the rectangular home that they give you. If the length of one side is 45 feet, and the other is 60 feet, then all you have to do is add both the numbers. However, the home is a rectangle, so you to find the perimeter of the other 2 sides. They must be the same because the house is a rectangle. So just add 60 feet twice, and 45 feet twice as well.

60+60=120 feet

45+45=90 feet

Total= 210 feet

The function rule C = 40n + 210 relates the number of months n to cost in dollars C of a phone plan and budget phone. Make a tab

Viefleur [7K]

Answer:

Input - Output

2 - $290

12 - $690

24 - $1170

Step-by-step explanation:

Cost after n months:

The cost after n months is given by the following function:

$C(n) = 40n + 210$

After 2 months:

This is C(2). So

$C(2) = 40(2) + 210 = 80 + 210 = 290$

After 12 months:

This is C(12). So

$C(12) = 40(12) + 210 = 480 + 210 = 690$

After 24 months:

This is C(24). So

$C(24) = 40(24) + 210 = 960 + 210 = 1170$

Table:

Input - Output

2 - $290

12 - $690

24 - $1170

X. Y

Dovator [93]

Answer:

Slope: 5

Y-intercept: 0

Equation: y=5x

Step-by-step explanation:

Lets look for an equation of the format y = mx + b, where m is the slope and b is the y-intercept (the value of y when x = 0).

Slope is defined as the "Rise/Run" of the line. The change in y(the rise) for a change in x(the run). This can be calculated by taking any two of the given data points. I'll pick (1,5) and (5,25):

Rise = (25 - 5) = 20

Run = (5 - 1) = 4

The Rise/Run, or slope, m, is (20/4) or 5.

The equation becomes y = 5x + b.

To find b, the y-intercept, enter any of the points into the equation and solve for b:

y = 5x + b

y = 5x + b for (4,20)

20 = 5*(4) + b

b = 0

The line goes through the origin at x = 0 (0,0).

The equation is y = 5x + 0 or just y = 5x.

Slope: 5

Y-intercept: 0

Equation: y=5x

Dollar is worth three and 3 1/2 kruneros. What is the value of 43 3/4 kruneros?

Korvikt [17]

Question:

One dollar is worth 3 1/2 kruneros. What is the value of 43 3/4 kruneros?

Answer:

The value of $43\frac{3}{4}$ kruneros is 12.5 dollars

Solution:

Given that,

Dollar is worth three and 3 1/2 kruneros

Which means,

$1 \text{ dollar } = 3\frac{1}{2} \text{ kruneros }\\\\1 \text{ dollar } = 3.5 \text{ kruneros }$

We have to find the value of $43\frac{3}{4}$ kruneros

Let us convert the mixed fractions to improper fractions

Multiply the whole number part by the fraction's denominator.

Add that to the numerator.

Then write the result on top of the denominator.

$43\frac{3}{4} = \frac{43 \times 4 + 3}{4} = \frac{175}{4} = 43.75$

So we have to find the value of 43.75 kruneros

Let "x" be the value of 43.75 kruneros

Then,

1 dollar = 3.5 kruneros

x dollar = 43.75 kruneros

This forms a proportion and we can solve the sum by cross multiply

$1 \times 43.75 = x \times 3.5\\\\x = \frac{43.75}{3.5}\\\\x = 12.5$

Thus value of $43\frac{3}{4}$ kruneros is 12.5 dollars
