x=13
Step-by-step explanation:
i don't know if that is right
They y-axis represents the -3 now all that you need to do is line it up to -3 and 3 in the graph
Answer:
94.4
Step-by-step explanation:
1.18 is 118%
1.18 times 80 is 94.4
The correct answer is a
(X+1)^2 - x^2=23
X^2 + 2x + 1 -x^2 =23
2x +1 =23
2x =22
X= 11
X+1= 12
Answer:
109.9 feet
Step-by-step explanation:
To find how many feet has Miguel traveled, we need to know the circunference of the tire:
C = pi*d = 3.14 * 28 = 87.92 inches
So, for each revolution of the tire, Miguel will travel 87.92 inches. So, to know the distance he will travel, we can do a rule of three:
1 revolution -> 87.92 inches
15 revolutions -> x inches
1/15 = 87.92/x
x = 87.92 * 15 = 1318.8 inches
As the question asks for the distance in feet, we convert from inch to foot by dividing the value of inches by 12, so:
distance in feet = 1318.8 / 12 = 109.9 feet
