Answer:
y⁷/x⁵ , I hope this helps
Answer:
10:7
Step-by-step explanation:
ratios are simply just like fractions!
this ratio (40:28) can be re-written as 40/28
now, you can simplify this to its lowest terms
40/28=20/14=10/7
first in those steps i re wrote the question, then divided by two, then divided by two again !
so, 40:28=10:7
--------------------------------
you can even check this by cross multiplying, since ratios are fractions

40x7=28x10
280=280
they are equivalent which means our ratio is correct :)

Answer:
y = 1/2x
Step-by-step explanation:
The slope is the rise (up) over run (left or right depending on if the number is negative) between points. So the next point on the graph is up 5 and over 10. this simplified is 1/2. Then you put this into y=mx which is y=1/2x
Answer:
(C) 245 miles
Step-by-step explanation:
We can view the starting and ending flight points as the hypotenuse of a right-angle triangle. Since the plane flew 125 miles south, the height of the triangle is 125 and we are given the hypotenuse as 275
If we designate the height as a and the hypotenuse as h, and the base as b then
h² = a² + b² by the Pythagorean theorem
or
b² = h² - a² ==> (h + a)(h - a) {x² - y² = (x + y) (x -y)}
Substituting known values
b² = 275² - 125² = (275 + 125)(275-125) = 400 x 150 = 60,000
b = √60000 = 244.94 and the closest answer is C: 245 miles
