Answer:
The answers are:
- The winner of the game was Janon.
- Henry came in last place.
Step-by-step explanation:
<u>Scores:</u>
- Henry: -7
- Janon: 0
- Clark: -5
The number line model is given by the attached picture. As you can see Henry's score is at the leftmost and Janon's score is at the rightmost. So Janon's score is the largest and she won the game. The last place is for Henry as he is at the leftmost (the lowest score).
Increase by 15% means multiply the original by 1.15. So 6500x1.15 is 7475.
To solve the first question, which is asking for the total amount of money, we have to add what Yvonne started with, with how much she earned.
4,000+960=4,960.
Now for the second question. It is asking for the unit rate of interest earned per year. So we have to divide 960 with the amount of years, which is 3.
960/3=320.
For the last question. 1 percent of 320 is 3.2, so we add 320 with 3.2 to increase the rate. Then we'll multiply the sum with 3 to find how much she would've earned. Finally, we'll add the amount with the 4,000 she started with.
320+3.2=323.2
323.2x3=969.6
4,000+969.6=4,969.6
So the answers are:
How much does she have in her account at the end of 3 years? <u>$4,960</u>
At what annual simple interest rate did the account grow? <u>$320 per yea</u>r
How many more dollars would she have in her account if the interest rate were 1% greater? <u>4,969.6</u>

Answer:
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
Triangles DEF and OEN are similar by AA Similarity Postulate
Remember that if two triangles are similar, then the ratio of its corresponding sides is proportional
In this problem
substitute the given values
Step-by-step explanation:
using Pythagoras a²+b²=c²
13²+16²
169+256=425
square root of 425 is 20.6 which round to 21 miles
