Answer:

Step-by-step explanation:

Since, Here Each tile has length one fourth in and width one sixth in.

That is inches and inches

And, the actual tiles have length one sixth ft and width one ninth ft.

That is inches and inches ( because 1 foot = 12 inches)

Thus the ratio of length of the actual length of tile =

And, The ratio of tile in the model of the actual area = Area of the tile in model/ actual area

Graph :

We are given with a graph of a line ABEquation of a line perpendicular to AB passes through point (7,6)

From the slope of line AB using any two points from the given line

A is (0,1) and B is (-2,5)

lets find out slope using slope formula

[tex]slope =\frac{y_2-y_1}{x_2-x_1} =\frac{5-1}{-2-0} =-2[/tex]

Slope of perpendicular lines are negative reciprocal of one another

Slope of perpendicular line is [tex]\frac{1}{2}[/tex]

Use point slope formula to find equation of the line

[tex]m=\frac{1}{2} , (7,6)[/tex]

Point slope formula

[tex]y-y_1=m(x-_1)\\y-6=\frac{1}{2} (x-7)\\y-6=0.5x-3.5\\y=0.5x-3.5+6\\y=0.5x+2.5[/tex]

Heavy rain in Oxford caused the Brandywine Creek to rise.

The creek rose three inches the first day, and each day twice as much as the previous day.

Then we have

a₁ = 3

r = 2

Then the amount of the creek rise on the fifth day will be

n = 5, Then we have

a₅ = 3 × 2⁴

a₅ = 3 × 16

As he earned $16 for walking his neighbour’s dog four times, we can find out the rate for walking their dog one time by dividing 16 by 4. Therefore, the rate for one walk is $4.

We can then find out how many times Brayden walked his neighbour’s dog when he earned $24 by dividing that by $4.

Therefore, the amount of times he walked his neighbour’s dog is 24/4 which is 6.

1 inch = 2.54 centimeters

2 inches = 2.54 × 2

= 5.08 centimeters

convert feet to centimeters

1 feet = 30.48 cm

6 feet = 182.88 centimeters

Total height = 6 feet 2 inches
