Answer:
$42
Step-by-step explanation:
40% of $63 is $25.2
$63 - $25.2 = $37.8
How much your paying without tax 37.8
7% of $63 is $4.41.
$37.8 + $4.41 = $42.21
Rounded 42.21 = 42
Im not 100% sure about the rounding but I hope this helps!
1 millimetre = 1/1000 = 1×10^-3 m
Answer:
The area of hub cap is 452.16 square centimeters.
Step-by-step explanation:
We are given the following in the question:
Radius of hubcap = 12 cm
A hubcap is of the shape of circle.
Area of hubcap = Area of circle
Area of hubcap =
where r is the radius of the hubcap.
Putting the values, we get,
Thus, the area of hub cap is 452.16 square centimeters.
Answer:
Infinite solutions
Step-by-step explanation:
Given is a system of equations.
-3x+y=10
-6x+2y=20
Equation I when multiplied by 2, gives as
-6x+2y =20 which is the same as equation 2 given.
This gives the two lines are not intersecting nor parallel. But the two lines are coincident with each other.
Hence each point on the line is solution.
Infinite solutions.
Let us try to solve and verify this
BY substitutition we have y = 3x+10, substitute in II
-6x+2(3x+10) =20
Or -6x+6x+20=20
20=20 Thus for any x, this becomes true.
Hence infinite solutions.
