Multiply the original number base on the decimal place in this case you'll have to multiply it by ten since the decimal is on tenth place. Once you do that, place the number as the numerator and use the number which you used to multiply as the denominator. 

3.3 =  33/10 = 3 3/10

A truck can be rented from Company A for $60 a day plus $0.60 per mile . Company B charges $30 a day plus $0.90 per mile to rent
Mamont248 [21]

x = the number of miles

y = the total cost

Company A:

0.60x + 60 = y     [Company A charges $60 plus $0.60 per mile(x)]

Company B:

0.90x + 30 = y      [Company B charges $30 plus $0.90 per mile(x)]

To find the number of miles where the costs for both companies are the same, you can set the equations equal to each other as the costs(y) are the same:

y = y      Substitute the equations into "y" (substitute (0.60x + 60) and (0.90x + 30) into "y" since y = 0.60x + 60 and y = 0.90x + 30)

0.60x + 60 = 0.90x + 30   To find x, isolate/get the variable "x" by itself. Subtract 30 on both sides

0.60x + 60 - 30 = 0.90x + 30 - 30

0.60x + 30 = 0.90x      Subtract 0.60x on both sides to get "x" on one side of the equation

0.60x - 0.60x + 30 = 0.90x - 0.60x

30 = 0.30x      Divide 0.30 on both sides to get "x" by itself

100 = x     100 miles

(if you need to find out the cost where both companies cost the same, you can substitute/plug in the value of x into one of the equations.)

0.60x + 60 = y     Plug in 100 into "x" since x = 100

0.60(100) + 60 = y

120 = y        At 100 miles, both companies cost $120

Find the area of the circle.
Yuri [45]

Answer:

50.24 centimeters squared

Step-by-step explanation:

The diameter (d) is 8 which means the radius is 4 (8/2)

we use the formula pi x radius^2

It says to use 3.14 for pi

so the equation is 3.14(4)^2=3.14 x 16 = 50.24

The function f(x) is given by the set of ordered pairs.
My name is Ann [436]
Answer: f(0) = 6.

Explanation:

Ther ordered pairs are: (x,y) or (x, f(x) )

So, (1,0) means that f(1) = 0 which denies the fourth choice.

(-10,2) means that f(-10) = 2 which denies the first choice

(0,6) means that f(0) = 6, which is the third choice. So, that is the true equation.
