Answer:

Step-by-step explanation:

4 cm × 1000 = 4000 cm = 40 meters

3 cm × 1000 = 3000 cm = 30 meters

A 4 cm by 3 cm section on the map represents 40 m by 30 m.

area = 40 m × 30 m = 1200 m²

The length and width

Nookie1986 [14]

Length is 15 ft and width is 12 ft

Step-by-step explanation:

Step 1: Given the area of the patio = 180 ft, length = l and width = l - 3. Area = length × width

180 = l (l - 3)

180 = l² - 3l

l² - 3l - 180 = 0

l = (3 ±√9 - 4 × 1 × -180)/2

= (3 ±√729)/2 = 3 ± 27/2

= 30/2, -24/2

= 15, -12 (Negative value is neglected)

∴ Length is 15

∴ Width = l - 3 = 12

Write an equation in

bixtya [17]

Answer:

Equation in slope-intercept form is $\mathbf{y=3x}$

Step-by-step explanation:

We need to write equation in slope-intercept form to represent the relationship shown in the table.

The general equation of slope-intercept form is: $y=mx+b$

where m is slope and b is y-intercept.

Finding slope using point (-2,-6) and (0,0)

The formula used is: $Slope=\frac{y_2-y_1}{x_2-x_1}$

We have $x_1=-2, y_1=-6, x_2=0, y_2=0$

Putting values and finding slope

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{0-(-6)}{0-(-2)}\\Slope=\frac{6}{2}\\Slope=3$

Using slope m= 3 and point (-2,-6) we can find y-intercept

$y=mx+b\\-6=3(-2)+b\\-6=-6+b\\b=-6+6\\b=0$

So, we have y-intercept b =0

Equation in slope-intercept form having slope m= 3 and y-intercept b =0 is:

$y=mx+b\\y=3x+0\\y=3x$

So, Equation in slope-intercept form is $\mathbf{y=3x}$

The bus fare in a city is $2.00. People who use the bus have the option of purchasing a monthly coupon book for $28.00. With the

LekaFEV [45]

Answer:

56 = 56

Step-by-step explanation:

Given:

Bus fare = $2.00

coupon book = 28.00

bus fare w/ coupon book = $1.00

let x be the number of bus rides.

2.00x = 1.00x + 28.00

2.00x - 1.00x = 28.00

1x = 28.00

x = 28.00

24 bus rides for both to have the same cost.

2.00x = 1.00x + 28

2.00(28) = 1.00(28) + 28

56 = 28 + 28

56 = 56
