Answer: You spent 5 hours babysitting.
Step-by-step explanation:
This situation can be represented by the equation y = 8x+ 10 where y is the money you earn and x is the number of hours.
So if y is equation to fifty dollars then what is x ?
50 = 8x +10 subtract 10 from both sides.
-10 -10
40 = 8x
x = 5
What is 4 hours 45 mins after 4:25 a.m.?
Add 4 hrs first:
4:25 + 4 hrs = ?
5:25, 6:25, 7:25, 8:25
4:25 a.m + 4 hrs = 8:25
8:25 a.m + 45 mins = ?
8:25 + 45 = 9:00
8:25 a.m + 45 mins = 9:00 a.m
4 hrs and 45 mins after 4:25 a.m is 9:00 a.m.
Answer:
= 486 in²
Step-by-step explanation:
Linear scale factor = Image distance/object distance
Therefore; Linear scale factor = OL'/OL
= 54/ 12
= 9/2
Area scale factor is equivalent to the square of linear scale factor
Thus;
Area scale factor = (9/2)²
= 81/4
Hence; 81/4 = Area of larger rectangle/Area of smaller rectangle
Area of the smaller rectangle = 4 ×6 = 24 in²
Therefore;
Area of enlarged or larger pic = 81/4× 24
<u>= 486 in²</u>
I’m pretty sure the power is 4
