Answer:

2250 ft ²

Step-by-step explanation:

Lawn is 50 feet across on each side so

Base (b) = 50ft

From front to back it is measured 45 feet so

height (h) = 45ft

Area of lawn = b x h

= 50 x 45

= 2250 ft²

Look at the graph shown<br> Which equation best represents the line?
Brilliant_brown [7]

y=\frac{11}{4}x +4 is the equation best represents the line.

Solution:

Take any two points on the line.

Let the points be (0, –4) and (4, 7).

x_1=0,y_1=-4,x_2=4, y_2=7

General form of equation of a line is y = mx + c

where m is the slope and c is the y-intercept of the line.

<em>y-intercept is the point which line crosses at y-axis.</em>

In the given line, y-intercept is 4.

c = 4

Slope of the line:

$m=\frac{y_2-y_1}{x_2-x_1}

$m=\frac{7-(-4)}{4-0}

$m=\frac{11}{4}

Equation of the line:

y = mx + c

y=\frac{11}{4}x +4

Hence y=\frac{11}{4}x +4 is the equation best represents the line.

What is the constant of proportionality in the table below?
kenny6666 [7]

Answer:  \dfrac{2}{5}

Step-by-step explanation:

The constant of proportionality 'k' between two variables ( one independent and one dependent ) is given by :-

k=\dfrac{\text{Value of dependent variable}}{\text{Value of independent variable}}

In the given table, independent variable = Days

Dependent variable = Total Miles

From first row,  Days = 3

Total Miles = 1\dfrac{1}{5}=\dfrac{6}{5}

Then, the constant of proportionality in the table

k=\dfrac{\dfrac{6}{5}}{3}=\dfrac{6}{5\times3}=\dfrac{2}{5}

Hence, the constant of proportionality in the table is \dfrac{2}{5} .
