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
Step-by-step explanation:
first you need m and m is -15/5 that means -3
your function is mx =y so your function is -3x= y
Answer:
93
Step-by-step explanation:
All the angles in a triangle add up to 180 degrees.
52 + 35 + x = 180
87 + x = 180
x = 93 degrees
Y=5x-9
Explanation:
y-y1=m(x-x1) Substitute the numbers in
y-1=5(x-2) Distribute the 5
y-1=5x-10 Add the 1 to both sides
y=5x-9
