54 is 75%
You set up a proportion
75/100=x/72
Mulitply 75×72 = 5400
Then divide it by 100=54
Therefore, 54 is 75% of 72

To solve this all you need to do is multiply 0.75 and 72 and you get 54.

Please help with 6 and 7
Maru [420]

Answer:

6a) i- 2hrs 36mins  ii- 3hrs 12mins

b) car A≈ 76.9km/h  car B≈ 62.5km/h

c)------

7a) 35km

b) car A=75km  car B=60km

c) 30km

d) car A≈36mins  car B≈48mins

Step-by-step explanation:

6a) Using the graph follow the lines until they finish then go downwards until you get to the x-axis. The x-axis is going up by 12mins for each square.

b) Using the answer from a, you divide 200km by the time.

For car A 2hrs 36mins becomes 2.6 because 36mins/60mins=0.6

∴ car A: 200/2.6≈ 76.92km/h

For car B 3hrs 12mins becomes 3.2 because 12mins/60mins=0.2

∴ car B: 200/3.2≈ 62.5km/h

7a) Using the graph go down from where the line of car A finished to meet car B. The y-axis is going up by 5km for each square.

b) Starting from the x-axis at 1 hour go upwards to see where you meet the car B line (60km) and car A line(75km). (sorry if that does not really make sense).

c) Difference from car A line to car B:

155km-125km=30km

d) Going across from 50km meet car A line and go down to see it has been travelling for approx. 36mins. Then continue across to car B line, go down to see it reached 50km at approx. 48mins.

Hope this helps.

Which is the best estimate of x based on rounding the constants and coefficients in the equation to the nearest integer 6.15 (x
artcher [175]
Your answer would be x = 12.41 

6.15 (x - 8.86) = 21.83
      *6.15 * 6.15

6.15x - 54.49 = 21.83
         + 54.49  + 54.49

6.15x = 76.32
/6.15    /6.15

x = 12.41
