Answer: 11 units

Step-by-step explanation:

The distance between points P(a,b) and Q(c,d) is given by :-

d=\sqrt{(d-b)^2+(c-a)^2}

Similarly , the distance between the two points (-7,5) and (4,5) is given by :-

d=\sqrt{(5-5)^2+(4-(-7))^2}\\\\\Rightarrow\ d=\sqrt{0+(11)^2}=11

Hence, the the distance between the two points = 11 units

Hannah earns $48 in 4 hours at this rate how many dollars will she earn in 20 hours?
baherus [9]
Hannah will earn $240 in 20 hours

Explanation: Since it tells you she earns $48 in 4 hours, you have to find how much she earns in 1 hour. So you do 48 divided by 4 (12) and that is how much she earns in 1 hour. Since the question is, how much does she earn in 20 hours, you multiply 12 x 20 and that equals 240 which means she earns $240 in 20 hours
