Answer:
15
Step-by-step explanation:
63 - 18 = 45 ( Minus the number of cakes that are left over)
45 / 3 = 15 (Divide by 3 to find out how many cakes they sold each day)
A) The probability that there are no boys in the car is given by:
Answer:
x = 1 + 2c/3
Step-by-step explanation:
Move all terms that don't contain x to the right side and solve.
Hoped this helped!
Answer:
b) Decrease the amplitude Increase the mass.
Step-by-step explanation:
The period does not depend on the amplitude. The period depends on the spring constant, k and the mass, m.
Mathematically,
T = 2pi × sqrt(m/k)
The more amplitude the more distance to cover but the faster it will cover the distance. The distance and speed will cancel each other out, so the period will remain the same. Increasing the mass increases the period of oscillation.
Answer:
65/66
Step-by-step explanation:
Find the reciprocal of the second number (11/13), which you find by flipping the top and bottom number so it would be 13/11. Now multiply the top two numbers which are 5 and 13, that equals 65. Multiply the bottom numbers, 6 and eleven which is 66. That is how you get 65 over 66.
