The formula for this is t = k/r, read "t varies inversely as r". If the info they give us is 4 hours and 35 miles per hour, we find that k = 140. Now use that 140 in another equation to solve for t: t = 140/45, and t = 3.1 hours

That is the answer
Answer: she waters 4 plants
Step-by-step explanation:
5cups /quart=20/x(x=#of quarts)
5x=20
x=20/5
x=4
(x,y) = (3,7)
Since both equations express y in terms of x we can equate them.
4x - 5 =2/3x + 5 (subtract 2/3x from both sides )
10/3x - 5 = 5 (add 5 to both sides)
10/3x = 10
multiply both sides by 3/10
x = (3× 10)/10 = 3
substitute x = 3 in either of the 2 given equations to obtain y-coordinate
y = 4x - 5 ⇒ y=(4 × 3) - 5 = 12 - 5 = 7
point of intersection = (3,7)
Answer: 624
Step-by-step explanation:
The area of a rhombus is the product of the diagonals divided by 2 so the area of the rhombus in this case is 12 * 16 / 2 or 96 multiply with 6.5 we get 624 so that's the answer
