Answer:
(i) The surface(sheet) of a conical tent is circular so we must use the formula for the area of a circle to find out;
Given the diameter 14, we must find the radius.
To find the radius we must do 1/2 of the diameter to get the radius.
14 x 1/2 = <u>7</u>, is the radius
Formula for area of a circle;
a = πr^2
where pi is 3.14 or 22/7, r is the radius which is being squared
Plug in the actual values:
a = πr^2
a = 3.14 x 7^2
a = 3.14 x 49
a = 153.86 square meters, is the area of the conical tent's sheet.
(ii) Since there are 153.86 meters in one sheet, we should multiply that by $12(because $12 per meter) to get the total cost.
So,
153.86 meters x $12 = $1,846.32, it would cost 1,846.32 dollars.
Answer:
y= 3x+4
Step-by-step explanation:
Slope-intercept form of an equation is
y=mx+b
m=slope
b=y-intercept
Just plug the values in and you get y=3x+4
The company charges $1.40 per mile.
Step-by-step explanation:
Given,
Cost of 6.5 miles ride = $12.00
Cost of 9 mile ride = $15.50
Let,
x be the cost per mile.
y be the pick up fee.
Total cost = Cost per mile*distance + pick up fee
According to statement;
6.5x+y=12.00 Eqn 1
9x+y=15.50 Eqn 2
Subtracting Eqn 1 from Eqn 2
Dividing both sides by 2.50
The company charges $1.40 per mile.
