To find the tax rate when given the initial price of an object and the final tax value, you use the equation: $350 * X = $22.75 (where X is the sales tax rate). Then solve:
$22.75/$350 = .065
So the rate is 6.5%
The angle between the legs labeled 
and 
is complementary to the angle with measure 31 degrees, so that angle has measure 90 - 31 = 59 degrees. Then
The slope is 2/-2, so -1. The y-intercept is 2. So, y=-x+2
On her map 1 inch is equal to 20 miles.
5x=100
divide both sides by 5
x=20
5 is for the 5 inches.
x is for the unknown.
100 is the 100 miles between the cities.
So the scale 1:20
Answer:
P=38
Step-by-step explanation:
At this case I would use the circumference formula for the rounded part.
The formula of the circumference is C=2πr.
So... We know that the radius is 5 which is half of the diameter. So... C=2π5 which is C=10π or C=31.4 which we divide by 4 because on the image is 1/4th of a circle and C/4 which C=7.85 so the P of the whole figure is P=10+10+5+5+7.85 which is P=37.85 which will be P=38.
Answer: P=38
