Answer:
20 by 20
Step-by-step explanation:
the new dimensions have to be 12 because 12×12 =144 so you would add 8 to 12 and get 20 for each side
Answer:
The equation which represents the function is given by,
x = 3y .
Step-by-step explanation:
The direct variation function contains the points, (-9, -3) and (-12, -4).
Here,
= 3
So, the equation which represents the function is given by,
x = 3y .
The length of the circle - <span>the product of the diameter and the number Pi
l = d</span>π
l = 900cm
π ≈ 3,1415 przyjmiemy wartość 3
900cm = d* 3 [:3
d = 300cm
<span>Becky rounded value of Pi , hence the difference in result
</span>
<span>More accurate calculation
</span>
l = d*π
900cm = d*3,1415
d = 900cm : 3,1415 = 286,49cm
<span>Becky overestimated the outcome</span>
Let the number of hours the ski jet was rented be x, then
For company A, Cost = 2.25x + 24
For company B, Cost = 2.75x + 23
Fro the cost to be the same: 2.25x + 24 = 2.75x + 23
2.75x - 2.25x = 24 - 23
0.5x = 1
x = 1/0.5 = 2
x = 2
The cost are the same after 2 hours.
