75 1/3 = 75.33
75.33% = 75.33/100
= 7533/10000
not sure if it can be simplified more than this
Product of a number and four is 4x
<span>12 more than that is 12+4x </span>
<span>fewer than 60 </span>
<span>12 + 4x < 60</span>
<span>The answer is -12 + 20x ≥ –6x 9. The inequality is –4(3 – 5x)≥ –6x 9. The first step is to multiply factors on the left side. The intermediary steps are: (-4)*(3) - (-4)*(5x) ≥ –6x 9. -12 - (-20x) ≥ –6x 9. So, the first step will be: -12 + 20x ≥ –6x 9.</span>
Answer:
Time in minutes = 66 2/3
Time in hours = 1.11
Step-by-step explanation:
Problem:
Time taken by both machine to make 20 yo-yo
let the time taken be x minutes
Given
Time taken by machine A to make 1 yo-yo = 5 mins
No. of yo-yo made by machine A in x minutes = x/5
Time taken by machine B to make 1 yo-yo = 10 mins
No. of yo-yo made by machine B in x minutes = x/10
Total no. of yo-yo made by both the machine = x/5 + x/10 = (2*x+x)/10
Total no. of yo-yo made by both the machine = 3x/10
But given that together they made 20 yo -yo
Thus,
3x/10 = 20
=> x = 20*10/3 = 200/3
Thus, it took 66 2/3 minutes to make 20 yo-yo by both of them
In one hour there is 60 minutes
Time taken in Hours will be = 200/3*60 = 200/180 = 10/9 = 1 1/9= 1.11 hours
Answer: 25 grapefruits
Step-by-step explanation:
They buy grapefruit at a price of 5 per dollar. This means that the price per grapefruit is:
= 1 / 5
= $0.20 per grapefruit.
They then sell at a price of 5 per $3. The selling price per grapefruit is:
= 3 / 5
= $0.60
The profit per grapefruit is:
= 0.60 - 0.20
= $0.40
In order to make a profit of $10, they should sell:
= 10 / 0.4
= 25 grapefruits
