Answer:
≈ 11.4 m
Step-by-step explanation:
The diagonal splits the rectangle into 2 right triangles , with legs 7 and 9 and the diagonal the hypotenuse.
Using Pythagoras' identity with h as the diagonal, then
h² = 7² + 9² = 49 + 81 = 130 ( take the square root of both sides )
h = ≈ 11.4 m ( to the nearest tenth )
From the equations given above, you can graph them by the slope and the y-intercept. I will be solving this by substitution method. It will be giving the same values as with graphing. We do as follows:
-2x + 30 <span>= -x + 21
-x = -9
x = 9
y = -9+21 = 12
Hope this helps. Have a nice day.

Answer:
41 miles per hour
Step-by-step explanation:
This is a fraction equal to
41 miles ÷ 1 gallon
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 1
41 miles ÷ 1
1 gallon ÷ 1
= 41 miles per gallon
I hope this works
