b. View graph
c. 6.40u
Step-by-step explanation:
knowing that the triangle area is equal to base by heigh between two, then:
The length of the longest altitude of your triangle is:
finally it can be seen that the position of the triangle does not matter, as long as the base and heigh are maintained, the area of the triangle will be the same
Well there is two ways that you an solve this equation. So I will tell you both and you can pick which one you prefer to use. Anyone is fine by me not that it really matters but anyways here it goes.
First way is... You want to find out what 15% off $63 so a way to do it is you first want to find out what 10% of $63 is which would be 6.3 because you jus have to move the decimal place to the left one place. Which leaves you with the left over 5% which is half of the 10% which we have got 6.3 so half of that would be 3.15. So add those together and you get 9.45. I hope this is what you wanted to know.
Just because!!!
The other way that you could have done it is that you could have done it the decimal way... $63x0.15 to get 9.45 the same answer as above.
Eric took 20 hours to do the job alone.
<u>Step-by-step explanation</u>:
<u>Given </u>:
- Total work = 75 packages
- Joe took 5 hours to complete the total work.
The amount of work Joe alone can do per hour = 75/5 = 15 packages.
The amount of work Joe and Eric together do per hour = 75/4 = 18.75
The amount of work Eric alone can do per hour = 18.75 - 15 = 3.75
The time Eric took to complete the entire work = 75 / 3.75 = 20 hours.
