The first and the third one
Answer:
15 14/15
Step-by-step explanation:
8 + 7 = 15
1/3 + 3/5
5/15 + 9/15
14/15
15 + 14/15 = 15 14/15
Answer:
n = -20
Step-by-step explanation:
Subtract 34 on both sides of the equation:
n = 14 - 34
n = -20

Answer:
2.42 feet
Step-by-step explanation:
the bicycle wheel rotates 5 times and travels 37.94 feet, then we know that the circumference of the wheel (the outside of the wheel as it touches the ground 5 times around) is 37.94/5 = 7.588
Then we use the formula for the circumference of a circle: 2(pi)(radius) = circumference
We plug in what we know 2(3.14)(radius) = 7.588 and then solve for the radius
We divide 2 from both sides of the equation (3.14)(radius) = 3.794
We divide pi from both sides (radius) = 1.208
Then the last step, we multiply the radius by 2, because we need the diameter, which is double the radius
1.208 * 2 = 2.416 or 2.42 rounded up
Final answer = 2.42 feet
