Answer:
Correct Answer: (8,2)
Step-by-step explanation:
<u>Dilation about the origin</u>
Most dilations in the coordinate plane use the origin, (0,0), as the center of the dilation.
In such cases, every point (x,y) dilated by a factor of k is mapped to the point (kx,ky).
The point R=(4,1) is dilated by a scale factor of 2 (k=2), thus the coordinates of its image are (2*4,2*1) = (8,2)
Answer:
The number of extra glasses required is 3954.
Step-by-step explanation:
Total volume of water in a bottle = 370 liters
Number of glasses, N = 46
capacity of each glass = 90 ml = 0.09 liter
The volume of water required to fill 46 glasses is
= 0.09 x 46 = 4.14 liter
The amount of water left = 370 - 4.14 = 355.86 liter
The number of extra glasses required to fill is
n = 355.86/0.09 = 3954
So, the number of extra glasses required is 3954.
18 - (-f) = 91
Subtracting a negative value changes to addition:
18 + f = 91
Subtract 18 from both sides:
F = 73
Since it is 25% all you would have to do is mutiply it by 4 to get 160. So in conclusion 160 is the answer.
