Subtract 240 from both sides:
Divide both sides by 12:
So, she needs to work at least 10 hours. Note that this is the minimum number of hours Ellie needs to work this week to earn at least $360 by the end of the month. This problem has no maximum: the more she works, the more she gains, so there's likely a typo in the question.
X is how much it costs for one hour, so when you multiply it by 3 1/2, you get the amount of money charged for 3 and a half hours.
The correct answer to this is 70
Answer:
15 m.
Step-by-step explanation:
If the figures are similar then the ratio of their heights is
∛128 / ∛250
= 0.8.
So 0.8 = 12/ h where h is the height of figure 1,
h = 12 / 0.8
= 15 m.
Answer: A (1)
Step-by-step explanation:
The way to find a common factor is by dividing the given numbers by the largest possible multiple that still gives you a whole number
A
49/1=49
62/1=62
80/1=80
This is an option
B
49/2=24.5
62/2=31
80/2=40
This is not an option, 24.5 is not a whole number
C
40/3=16.333(repeating)
This is not an option, you are not given a whole number
D
49/4=12.25
This is also not an option, 12.25 is not a whole number
Answer
Our only possible answer is A-1
