- A rectangular pool has an area of 140 square feet. If the length of the
pool is 16 feet, what is its width?
Answers
Answer:
8.75 feet
Step-by-step explanation:
Use the area formula, A = lw, where l is the length and w is the width
Plug in the area and length, and solve for w:
A = lw
140 = 16w
8.75 = w
So, the width is 8.75 feet

Answers
Answer:
B
Step-by-step explanation:
residual is the given - predicted
residual 1: -0.42
residual 2: 0.35
so on and so forth
B matches up with the first two coordinates
The residuals are 0.42, 0.35, -0.08, 0.79, and -0.65 because residuals are the difference between the actual and predicted.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
The residual = actual—predicted
We have given:
X Given Predicted Residual value
1 0.7 0.28 0.42
2 2.3 1.95 0.35
3 4.1 4.18 -0.08
4 7.2 6.41 0.79
5 8 8.65 -0.65
Thus, the residuals are 0.42, 0.35, -0.08, 0.79, and -0.65 because residuals are the difference between the actual and predicted.

The first week, the students collected 2,054 books. About how many books did the students collect for the hospitals the second week? Choose the better estimate.
Answers
Answer:
3799 books
Step-by-step explanation:
We have the total number of books collected as 5,853 books
In the first week, a total of 2,054 books were collected.
If the collection of books went on for two weeks;
Hence in the second week, a total of (5,853 - 2,054) were collected.
Therefore, number of books collected in the second week = 3799 books

Step-by-step explanation:
log(5x+10)-log(4x+12)=1-2log(3)
log(5x+10/4x+12)=1-2log(3)
log(5x+10/4x+12)=log(10)+log(3^-2)
log(5x+10/4x+12)=log(10×3^-2)
log(5x+10/4x+12)=log(10×1/9)
log(5x+10/4x+12)=log(10/9)
