Hello!
Solve for the distance by solving for the circumference of the wheels:
C = 2rπ
C = 2(8.5)(π)
C = 17π
The wheels make 15 rotations, so multiply the circumference by 15:
17π × 15 = 255π or ≈ 800.7 inches
I am pretty sure it's Y=2/5x - 4.8. I'm sorry if it's wrong
Answer:
d/r = t
Step-by-step explanation:
d = r * t
d/r = t
Answer: There are 7 nickles, 21 dimes and 16 quarters.
Step-by-step explanation:
Since we have given that
Number of coins = 44
Let the number of nickels be 'x'.
Let the number of dimes be '3x'.
Let the number of quarters be
According to question, we get
So, there are 7 nickles,
3x =
Hence, there are 7 nickles, 21 dimes and 16 quarters.
Answer:
Yes, this is a right triangle.
Step-by-step explanation:
The Pythagorean Theorem states that if the sum of the squares of the two small sides of a triangle add up to the square of the longest side, then the triangle is a right triangle: a² + b² = c², where a and b are the smallest sides (called legs) and c is the longest side (called the hypotenuse).
Here, the two smallest sides are 10 and 49.5, so let's square them, add them up, and see if they add up to 50.5²:
10² = 100
49.5² = 2450.25
100 + 2450.25 = 2550.25
50.5² = 2550.25
Since 10² + 49.5² equals 50.5², we know that this is a right triangle.
Thus, yes, this is a right triangle.
