Answer:
19/2 = 9.5. This is the speed she can ride in a single hour. At that speed, she would travel 9.5/3 miles in 1/3 of an hour. 9.5/3 = 3.1666666666666667
Step-by-step explanation:
Answer:
a) $2.75 b) $13.75
Step-by-step explanation:
since 8.25 is the total cost of 3 books, inorder to find the cost of 1 book, divide 8.25/3
that equals = $2.75
then we need to find the cost of 5 books, so multiply the cost of 1 book by 5
so 2.75*5 = $13.75
Parallel lines have the same slope but different y-intercepts. Which answer has the same slope as the one above? Hint: m is the slope (coefficient of x)
Answer:
3/2
Step-by-step explanation:
We can use the slope formula to find the slope of the line
m = ( y2-y1)/(x2-x1)
Using the points (0,-4) and (2,-1)
m = ( -1 - -4)/( 2 - 0)
= (-1+4)/ (2 -0)
= 3/2
Ф = 3π/4. Transform it into Rectangular (or Cartesian) form .
The coordinates of Ф are x ,y in rectangular form ==> so:
tan(Ф) = y/x and y=x . tan(Ф) ==> y= x. tan(3π/4). we know that tan(3π/4)= - 1
Hence y = - x
