On 14 I said slope, it is the same thing as rate of change
X = 35
use the formula a^2 + b^2 = c^2 in order to find the hypotenuse, which is x.
21^2 + 28^2 = c^2
441 + 784 = c^2
1225 = c^2
35 = c
x = 35
Answer:
In inches, this would be 7 inches.
Step-by-step explanation:
Your scale is 1 in.:25 mi, right?
so if we take 175 mi and divide it by 25:
175÷25=7
For so it being 7 inches on your map.
Answer:
x = 0
Step-by-step explanation:
Let's simplify first:
x² + x² + x² = x² + x² =>
3x² = 2x² =>
3x² - 2x² = 0 =>
x² = 0
x = √0 = 0
The ratio of girls to boys would be 16:12 because if you divide 28 by 2 you get 14. subtract 2 to on one of them and add the two to the other. You get 12 and 16. There is a difference of 4 to them and when you add them together you get 28. :)
