Answer:
Given the equation, the radius of the circle is 7.
Step-by-step explanation:
We are given the equation, x² + y² = 49.
In order to find the radius, we have to calculate the square root of 49. This is because the original form of the equation is x² + y² = r².
So, the radius of the circle is 7.
Answer:
20 + 2x = 4x
Step-by-step explanation:
So you are setting the two expressions equal to each other.
buying a membership card and paying each time looks like this: 20 + 2x where x is the number of times you go to the gym. 20 dollars base then 2 each time you go.
4 each time you go is just 4x
so just set the two equal to each other.
20 + 2x = 4x
If you solve it you will get x = something, which would be the number of times to make the two equal.
So, problem statement tells you that 1lb = 16oz and that 1oz = 28.3g. That means that 1lb = 16 * 28.3g = 452.8g
You have three items, convert their weights to grams:
1) 800g
2) 1.6lb = 1.6 * 452.8g = 724.48g
3) 30oz = 30 * 28.3g = 849g
So, sorting from greatest:
3, 2, 1, or: 30oz, 1.6lb, 800g.
