Answer:
First five terms are:
4300, 4240, 4180, 4120, 4060
Step-by-step explanation:
Minus 60 from the predicted number of cars in the first month to get the second month, then do the same for the predicted number of cars in the second month to get the third month and so on.
The expression for the nth term would be = 4300 - (n-1)(60)
= 4360 - 60n
Answer:
Step-by-step explanation:
The tangent segment is perpendicular to the diameter, so the triangle is a right triangle (not just based on its appearance). A property of circles is: a tangent is perpendicular to the radius drawn to the point of tangency.
In the right triangle, one leg has length 12.6, and the hypotenuse has length 21.
Apply the Pythagorean Theorem: (leg)^2 + (leg)^2 = (hypotenuse)^2
Oh, and the diameter has length 2x!

44
Step-by-step explanation:
let boys be x and girls be y
x/y=5/6
x=5y/6....(1)
if 6 boys join the club that will be x+6
Therefore:
(x+6)/y=13/12
13y=12x+72
13y-12x=72
Recall x=5y/6
Therefore:
13y-12(5y/6)=72
13y-(2*5y)=72
13y-10y=72
3y=72
y=24 people
Therefore:
x=(5*24)/6
x=20 people
Therefore people in the club before are 20+24=44
No, 1/8 is smaller because 2/10 is equivalent to 1/5 and 1/5 is larger than 1/8.
