Michael drove from home to work at an average speed of 50 mph. His return trip home took 30 minutes longer because he could only
Sladkaya [172]

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

I need to know the surface area of this shape
Sophie [7]
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

lianna [129]
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!
