Answer: 19 birds were at the shelter on Wednesday.
Step-by-step explanation:
Let x represent the number of birds that were at the shelter on Wednesday.
Let y represent the number of birds that were at the shelter on Wednesday.
Nicole found a record showing that there were a total of 40 birds and cats on Wednesday. This means that
x + y = 40
The animal shelter spends $5.50 per day to care for each bird and $8.50 per day to care for each cat. Nicole noticed that the shelter spent $283.00 caring for birds and cats on Wednesday. This means that
5.5x + 8.5y = 283 - - - - - - - - - - - - - -1
Substituting x = 40 - y into equation 1, it becomes
5.5(40 - y) + 8.5y = 283
220 - 5.5y + 8.5y = 283
- 5.5y + 8.5y = 283 - 220
3y = 63
y = 63/3 = 21
x = 40 - y = 40 - 21
x = 19
A scenario that would best model the graph on Holly, her home, and school is:
- Holly was trying to get to school from home but fell ill when 4 miles from home.
- Holly waited to catch her breath and gain some strength.
- Holly reached school and reported her condition.
- The school allowed her to go home.
<h3>What happened Holly's journey to school?</h3>
As Holly was heading to school, she felt uneasy and had to wait for 10 mins to catch her breath.
After doing so, she then continued to school which was 6 miles from her home. When she got there, she went to the nurse's office.
She waited in school for 15 minutes and was then told to go home to rest and recuperate. She then made the journey back home in a car and arrived in 10 minutes.

No. It's rational. The solutions are +10 and -10.
Answer:
Therefore, we conclude that the probability is P=0.3456.
Step-by-step explanation:
We know that there is a 0.60 probability that a random student at UMSL has watched Game of Gnomes. We calaculate the probability that 3 of 4 students watched Game of Gnomes.
Therefore, we get:
Therefore, we conclude that the probability is P=0.3456.
To change a decimal into a percent,
move the decimal point 2 places that way ==> .
Examples:
0.25 = 25 %
0.8439 = 84.39 %
