The diagram below shows the dimensions of a rectangular house with a rectangular backyard. What is the total area, in square feet, of the house and backyard?
Answer:
D) 5,200
Step-by-step explanation:
The formula to find the area of a r rectangle: l x w, where l is the length and w is width.
Area of the backyard: 50 x 80
= 4,000 ft
Area of the house: 40 x 30
= 1,200 ft
Total = 4,000 + 1,200
= 5,200 ft²
Gas Tank- 11 in , 1.25 ft, 1.75 ft
The gas tank is 20% full. Use the current price of gas in your community to find the cost to fill the tank (1 gal = 231 in^3
Current price = 3.79
Answer:
$45.48
Step-by-step explanation:
Given that:
Gas tank are 11 inches, 1.25 feet and 1.75 feet.
The gas tank is 20% full. Use the current price of gas in your community to find the cost to fill the tank (1 gal = 231 in³)
Current price = 3.79
Solution:
Formula: Volume = LWH
While,
L = Length
W = Width
H = Height
Since we, know that
Gas tank are 11 inches, 1.25 feet and 1.75 feet.
We have to convert either to inches or feet.
Note that: 1 feet = 12 inches
I will convert feet to inches
Thus,
1.25 × 12 = 15
1.75 × 12 = 21
Since 11 is already in inches we don't have to change that.
Now from the formula: LWH
Therefore, we have:
V = 11 × 15 × 21
V = 3465
Now, from the given the gas tank is 20% full
Finding 20%:
3465 × 20 % = 693
Now subtract to find the other 80%
3465 - 693 = 2772
Since 1 gal = 231 in ³
2772/ 231 = 12
Now, 12 mulitply by the current price of gas given:
12 × 3.79 = 45.48
Hence, the cost to fill the tank is $45.48

Answer:
$45.48
Step-by-step explanation:
Convert to inches
1.25 × 12 = 15
1.75 × 12 = 21
Since 11 is already in inches we don't have to change that.
Now from the formula: LWH
Therefore, we have:
V = 11 × 15 × 21
V = 3465
Now, from the given the gas tank is 20% full
Finding 20%:
3465 × 20 % = 693
Now subtract to find the other 80%
3465 - 693 = 2772
Since 1 gal = 231 in ³
2772/ 231 = 12
Now, 12 mulitply by the current price of gas given:
12 × 3.79 = 45.48
Hence, the cost to fill the tank is $45.48

What is the interquartile range of this data set?
Answer:
13
Step-by-step explanation:
To find the interquartile range you would first have to find the median. If you list the number in least to greatest order you will find that the median is 30.5. After you find the median you will spilt the data set up. So on one side it will be 20, 25, 30 and 30, the other side you be 31, 40, 41, and 49. Next, you would find the median of the first set that I listed which is 27.5. You would do the same for the second set and find the median which is 40.5. You would then subtract the first sets median from the second sets median which is 40.5-27.5 and that is 13.

Answer:
x = 2, x = -2
Step-by-step explanation:
2x^2 = 8
divide both sides by 2
x^2 = 4
This is a perfect square!
square root on both sides
x = 2, or -2
(2 negatives multiplied = positive)
Check work

2*4 = 8
8 = 8 :)
Check work
2*(-2)^2 = 8

What is the slope of the line that passes through the points (-7, -2)(−7,−2) and (-15, -14)(−15,−14)? Write your answer in the simplest form.
Answer: The slope is positive, which tells us that the line has an upward direction.
Step-by-step explanation:
The slope of a line is calculated by finding the difference of the y-coordinates and dividing it by the difference of the x-coordinates.
In this case, the difference of the y-coordinates is -2 - (-14) = 12, and the difference of the x-coordinates is -7 - (-15) = 8.
The slope is therefore 12/8 = 1.5.
