Could you please give a little more info on this problem?? I wanna help but im confused
Answers:
- Zainab made more money
- She made $2.50 more
=======================================================
Explanation:
To find the hourly rate, we divide the money made over the number of hours.
- Zainab's hourly rate = 44/8 = $5.50 per hour
- Keziah's hourly rate = 47.25/9 = $5.25 per hour
Then we'll multiply each of these results by 10 to figure out how much they made over the 10 hours
- Zainab: 5.50*10 = 55 dollars
- Keziah: 5.25*10 = 52.50 dollars
We see that Zainab made more money and she made 55-52.5 = 2.50 dollars more.
The way I usually solve these problems is by using trial and error. A good way to find out about where your numbers are is by finding the square root of that number. The square root of 306 is about 17.5, so I would start with 16 and 17. 17*16=272, so I would know I had to go higher. I would then try 17*18 which equals 306. Because you need the numbers to be negative, you would make both of those numbers negative. The two integers would then be -17 and -18.
Answer:
Option: B is the correct answer.
B) Construct the <u>center of a given circle.</u>
Step-by-step explanation:
The center of the circle is constructed as:
- Draw a chord AB and construct it's perpendicular bisector.
- Draw another chord CD and construct it's perpendicular bisector.
- The point where the perpendicular bisectors of both the chord meet gives us the center of the given circle.
Hence, option B is correct we are given a geometric construction of center of a given circle.
