Answer: $24.47
Step-by-step explanation: I don’t understand the kilometers.
Answer:
1) m=-7/5
2) m=-7/5
3) parallel
Step-by-step explanation:
the first part:
graph the points and then find the slope
m=-7/5
the second part:
slope= m in y=mx+b
m=-7/5
the last part:
they are parallel because they have the same slope
Answer: The tip left for the servers was $14.80
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Total cost of the food (before tax) = $82.25
</em>
- <em>Tip = 18% of the amount before the tax
</em>
So, to calculate the tip we have to multiply the cost of the food before tax ($82.25) by the 0.18 (percentage in decimal form, 18/100= 0.18).
Mathematically speaking:
82.25 x 0.18 = $14.80
The tip left for the servers was $14.80
When it comes to hundreds and thousands and even millions, you can tell how much bigger something is by how many more zeros are at the end. Each new zero added, is another rank up. The system goes:
1=10x bigger
2=100x bigger
3=1000x bigger
4=10000x bigger
5=100000 bigger
so on and so forth. There are 2 zeros in 700, and only 1 zero in 70, the difference in zeros is 1, so you can refer to the chart and conclude that 700 is 10 times bigger than 70. You could also divide 700 by 70 to get 10. This is more accurate, but the chart is simpler.
