Answer:
b is the answer I believe so because it have to be greater than 0
Step-by-step explanation:
I hope it's right and if not my bad
First we have to find 18% of $55.82, which we can do by using the equation 55.82 x 0.18
55.82 x 0.18 = 10.05
so the tip = $10.05
now we just add it to the original bill
55.82 + 10.05 = 65.87
so the total cost = $65.87

Step-by-step explanation:
Answer:
230
Step-by-step explanation:
The scale factor is by what amount the bigger is bigger than smaller, or what amount the smaller is smaller than the bigger.
Now, we first have to use same units. Lets use cm.
We know 100 cm = 1 meter
For projection (big one):
10 meters by 4.6 meters, that, in cm would be:
10*100 = 1000 cm
4.6 * 100 = 460 cm
So, the projection is:
1000cm (long) by 460 cm (tall)
The T-Rex on lens is:
x cm (long) by 2 cm (tall)
So, the height is given for both, so we can see that
2cm in lens is to 460 cm in projector
The scale factor is:
460/2 = 230
That means the projected image is 230 times the real image
THe scale factor is 230
