Answer:
351.86 Square inches (to the nearest hundredth)
Step-by-step explanation:
The shaded region is referred to as the Annulus of two concentric circles.
To find the area of the shaded region is to subtract the area of the smaller circle from the area of the larger circle.
Let the radius of the larger circle=R
Let the radius of the smaller circle=r
Area of shaded region
R=11cm, r=3cm
Therefore:
Area of shaded region
There are 4 multiples of 7 between 1 and 30, so there is 4 out of 30 tickets that are a multiple of 7. There is a 0.133 chance of pulling a <span>ticket that has a number which is a multiple of 7.</span>
A=5/12 if your solving for a
Part A: It is a non-linear function because it doesn't continue at a constant rate. The last y value increased by 2 instead of 4 like the previous coordinates. There's no consistency if that makes sense.
Part B: linear- (1,2) (2,4), (3,6) Notice how the x increases by the same amount (1) and the y increases by the same amount (2)
non-linear- (2,4) (5,10) (7,11) The x and y values are increasing by completely different amounts in this one.
we'll proceed along the same lines as the previous one.
the cost of the boots is 90.10 and that includes 6.25% sales tax, so if "x" is the 100%, then 90.10 is really the 106.25%, because is including the extra 6.25%.
so if that's the cost of each boot, without tax, then the markup will be 88.8 - 50.88 = 37.92.
if the 100% is 88.8, how much is 37.92 off of it in percentage?
