A= 15+z+ square root 17(z+15)/ z-2
z=2a^2/(a-1)^2 + 30a/(a-1)^2 - 15/(a-1)^2
No its not a polygon.
It has a curve where as a polygon is a plane figure with at least three straight sides and angles
Thanks for the help xoxoate!
Answer:
The error was on the diameter. The tire diameter was supposed to be;
4.6+15+4.6=24.2
The student only includes one sidewall width
Step-by-step explanation:
The question is on circumerence of a tire
Here we apply the formulae for circumference of a circle
C=2 
×r or × d where r is the radius of the tire and d is the diameter
Finding d= diameter of rim + sidewall to the right +sidewall to the left
d= 15+4.6+4.6=24.2 inches
r=d/2= 12.1
C=2 ××r
C=2×3.14×12.1 =75.99 Inches
Answer:
Box A contains =3pain pencils and 9 plain pens
Box B contains 7color pencils and 3 crayons
probablilty=event space/sample space or number of outcome/total no.of possible outcome
probability that a plain pencil from the first box will be selected =3/11
probability that a color pencil from the second box will be selected=7/10
therefore probability that a plain pencil from the first box and a color pencil from second box will be selected=3/11 plus 7/10=110/110=1.
therefore the answer is 1.
