Answer:
12/20
60%
Step-by-step explanation:
A fraction has a numerator and denominator
The numerator is the total number of heads
The denominator is the total number of times the coin was flipped
To express in percent form, multiply by 100
x 100 = 60%
Y = 10x + 20
x = number of cars washed for charity
y = amount earned for the charity
slope = 10
This means that :
<span>
For every car washed for charity, the amount earned for the charity increases by $10. </span>

Complete Question
A turtle can walk 1/12 of a kilometer in an hour. The turtle is 1/5 of a kilometer away from a pond.At this speed how long will it take the turtle to reach the pond?
From the above question:
1/12 km = 1 hour
1/5 km = x hour
Cross Multiply
1/12 km × x hour = 1/5 km × 1 hour
x hour = 1/5 km × 1 hour/1/12 km
x hour = 1/5 km ÷ 1/12 km
x hour = 1/5 × 12 hour
x hour = 12/5 hour
x hour = 2 2/5 hour
Answer:
3rd quadrant
Step-by-step explanation:
In the second quadrant, x is negative and y is positive so that means that the original values of x and y are both negative. The quadrant in which those kinds of points are located is Quadrant III.
The formula for area is pi x r^2 (pi times radius squared) so, for number 7 youre given the radius or "r", which is half the length of the inside of the cirlce. On a calculator: you would do 8 times 8 (8^2) because that's the radius squared and then you should get 64 and times 64 by 3.14 or use the pi button depending on what your teacher prefers you to use.
When you're given diameter or "d" which represents the is equal to the radius times 2. So, for example, number 8 the diameter is 26 so, the radius is 13. Use the formula for area just like in number 7 to find the area of this circle.
Make sure you pay attention to what information youre given (whether its "d", Diameter, "r" or radius. Use those two lists of steps for solving numbers 7 through 12.
For numbers 13-15: use the number (22/7) instead of 3.14 or the pi button on your calculator and do the same steps!!!!!
Let me know if you still need help after this:) happy math solving!
