Y *x =20
y +x =9
rewrite 1st eq. as y = 20/x
subsituute that into 2nd eq.
20/x +x =9
multiply each term by X
20 +x^2 = 9x
subtract 9x from each side:
x^2 - 9x +20 = 0
now factor:
(x-5) (x-4) = 0
solve for x
5-5 = 0
4-4 = 0
so X can be 4 or 5
replace x into equations and solve for Y
so when X = 4, Y = 5
When X = 5, Y = 4
x= 5,4
y = 4,5
Answer:
The measure of angle KSP is 
Step-by-step explanation:
step 1
Find the measure of angle ISP
we know that
The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.
we have
substitute
step 2
Find the measure of angle KSP
we know that
----> by supplementary angles
we have
substitute
The diameter of the wheel is 30 inches, therefore the radius is 15 inches.
We calculate the angular velocity (w) of this using the formula:
w = v / r
w = 60 mph / 15 inches = 4 mph / inches
Since the flange is 1 inch beyond the rim, hence the effective radius for this is 16 inches.So the velocity on the outer edge is:
v = w r
v = (4 mph / inches) * 16 inchesv = 64 mph
