Answer:
100 miles
Step-by-step explanation:
Given :
To work :
speed = 50mph
Let time taken = x
From work :
speed = 40mph
30 minutes = 30/60 = 0.5
Time taken = x + 0.5
Distance from home to work :
Distance = speed * time
To work distance = from work distance
This can be algebraically expressed as :
50 * x = 40(x + 0.5)
50x = 40x + 20
50x - 40x = 20
10x = 20
x = 20/10
x = 2
Hence,
Distance = 50 * 2 = 100
The the distance from home to work = 100 miles
The area is the area of 2 pairs of congruent triangles and one rectangle. Use the formulas for the areas of these figures, then add results.
Front triangle area (A = (1/2)bh)
.. = (1/2)(16 m)*(25 m) = 200 m^2
Right side triangle
.. = (1/2)(22 m)*(24 m) = 264 m^2
Base (A = lw)
.. = (16 m)*(22 m) = 352 m^2
Total area
.. 2*front triangle +2*side triangle +base
.. = 2*200 m^2 +2*264 m^2 +352 m^2
.. = 1280 m^2
Hello!
The five-number summary is the lowest number, highest number, median, quartile 1 and quartile 3
First you should order the numbers from least to greatest.
65, 78, 80, 90, 92, 92, 98, 101,106, 112, 116, 119
The lowest number is 65
The highest number is 119
Next you can find the median
The median is the number in the middle
The two numbers in the middle are 92 and 98
Since there are two numbers you take the average
92 + 98 = 190
190/2 = 95
The median is 95
Now we know the answer is either A or B
Next you can find the lower quartile
The lower quartile is the median of the numbers under the median
So we list all the numbers under 95
65, 78, 80, 90, 92, 92
The numbers in the middle are 80 and 90
The average between these two is 85
So the lower quartile is 85
From this we know the answer is B
The answer is B
Hope this helps!
