Mr. D'Agostino decided he wanted to build a pool in his backyard this summer. He sketched a drawing that had a scale of 1 in. = 4 feet. If the drawing had a length of 4 feet and a width of 5 feet, what is the actual area of the pool?
Answer:
46080 ft²
Step-by-step explanation:
Given :
Scale :
1 in = 4 feets
Recall :
I foot =. 12 inches
Length of drawing = 4 feets
Length of drawing in inches = 4 * 12 = 48 inches
Width of drawing = 5 feets
Width of drawing in inches = 5 * 12 = 60 inches
Actual length of pool = 48 * 4 = 192 feets
Actual width of pool = 60 * 4 = 240 feets
The actual area of the pool :
Length * width
192 feets * 240 feets = 46080 ft²
For what value(s) of w does the equation 7 + 3x - 1 = w(x + 2) have infinitely many solutions?
Answer:
w=3
Step-by-step explanation:
7 + 3x - 1 = w(x + 2)
Solve for w
Distribute
7 + 3x - 1 = wx + 2w
Combine like terms
3x+6 = wx+2w
For this to have infinite terms
3x = wx and 6 = 2w
3x = wx
Divide by x
3 =w
and 6 = 2w
Divide by 2
6/2 = 2w/2
3 =w
When w = 3, there will be infinitely many solutions

A construction company spends w weeks extending an existing road. The existing road is 5 miles long. Each week the company completes 0.2 miles of the extension. Which equation models the total length (L) of the road?
A. L = 0.2w + 5
B. L = 0.2w - 5
C. w = 0.2L + 5
D. w = 0.2L - 5
Answer:
L = 0.2w + 5
Since there is already 5 miles, your adding 0.2w. Its not 0.2L because that is the total length and its the sum.
Answer:
L= 0.22+5

Martina and Ashanti worked together on an art project. They began working at 3:25 p.M. And finished working at 5:15 p.M. How long did the girls work together on their art project?
Answer:
The girls worked together on their art project for 1 hour and 50 minutes.
Step-by-step explanation:
In order to find the answer you have to find the difference between the time they began working and the tine they finished working. You have to subtract 3:25 from 5:15.
Since 25 minutes on the time they began working is higher than 15 minutes, you have to subtract 1 from the time they finished working that is 5 hours:
5-1=4
Then, you have to increase the minutes on the time they finished working by 60:
15+60=75
Now, you have to subtract the minutes which would be 25 from 75:
75-25=50
Finally, you have to subtract the hours which would be 4 minus 3:
4-3=1
The result would be 1 hour and 50 minutes.
According to this, the answer is that the girls worked together on their art project for 1 hour and 50 minutes.

To find the average of some quantities , add them together and then divide the total by the number of
Answer:
quantities or total number of observations
Step-by-step explanation:
Average also known as mean is a measure of central tendency. It is determined by adding the numbers together and dividing it by the total number
Average = sum of the numbers / total number
For example, there are 3 numbers 3 , 6, 9
Average = ( 3 + 6 + 9) / 3 = 18 / 3 = 6

After 10 weeks of work, bob has $1200. After 15 weeks of work Bob has $1800. After 20 weeks of work Bob has $2400. Write the firs four terms of a sequence that represents this situation. Writ and equation to model the situation
Answer:
1200,1800,2400,3000
5x = 600x
Step-by-step explanation:
The first four terms would be
1200,1800,2400,3000
As we can see that
After 10 weeks of work bob has $1200
After 15 weeks of work, bob has $1,800
So the more the weeks would be, the more the earnings it is
And, the difference of the earnings is
= $1,800 -$1,200
= $600
The equation would be
5x = 600x
So if we assume x = 1
So
5 = 600
if we assume x = 2
So
10 = 1200
and so on
