Answer: 1.2miles
Step-by-step explanation:
Divide 15 by 50 to get how far she rides in 1 minute that multiply that by 60 to get how far she rides in 1 hour.
Let the unknown number be x
13x+72= -23x
13x+23x= -72
36x= -72
x= -2
Answer: 54 square feet
Step-by-step explanation:
To find perimeter of a rectangle we must use the formula l+l+w+w=p where l and w represent width and length
Since we know length and width is x=12 just substitute so
15+15+12+12=54 so 54 is the perimeter
Answer:
∂u/∂xi = i·cos(sn)
Step-by-step explanation:
For u = sin(v), the partial derivative of u with respect to xi is ...
∂u/∂xi = cos(v)·∂v/xi
In this case, v=sn, and ∂sn/∂xi = i, so the derivatives of interest are ...
∂u/∂xi = i·cos(sn)
Answer:
55m
Step-by-step explanation:
a²+b²=c²
19 x 19 = 361
52 x 52 = 2704
2704 + 361= 3065
the square root of 3065 is 55.4 so round that to 55.
