Answer:
10 miles per hour
Step-by-step explanation:
there are 60 minutes in an hour once you covert you have that it took 1.17 hours then there are 5280 feet in a mile so you convert and get 12.075 miles
you divide
12.075/1.17 = 10.3205128
then you simplify to the nearest whole number and get 10
The distance between them is 4.0.
The equation would be 1.5-(-2.5)=d
Hope that helps ya :)
The answer is C because 4 + 15 = 19.
Step-by-step explanation:
h = height of rectangle (should be "length", but ok)
w = width of rectangle
w = h + 97
the diagonal of the rectangle is the Hypotenuse (baseline) of a right-angled triangle with the legs being one height and one width side of the rectangle.
so, we use Pythagoras
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90° angle).
diagonal² = h² + (h + 97)² = h² + h² + 2×97h + 97²
113² = 12769 = 2h² + 194h + 9409
3360 = 2h² + 194h
1680 = h² + 97h = (h + 97/2)² - 9409/4
(completing the square)
6720/4 + 9409/4 = (h + 97/2)²
16129/4 = (h + 97/2)²
127/2 = h + 97/2
30/2 = h = 15
the height is 15.0 in
