Answer:

54 square feet

Step-by-step explanation:

We need to find the area of the surface touching the floor and deduct it from the total surface area of the block.

The surface area of the entire block is given as:

A = 2(lw + lh + wh)

where l = length

w = width

h = height

The dimensions of the block are 2 feet by 3 feet by 6 feet. This means that:

l = 2 feet, h = 3 feet, w = 6 feet

Therefore, the total surface area is:

A = 2[(2 * 3) + (2 * 6) + (3 * 6)]

A = 2(6 + 12 + 18)

A = 2(36)

A = 72 square feet

The area of the surface that does not need covering is:

A = 3 * 6 = 18 square feet

The surface area of the part of the block that needs covering is therefore:

A = 72 - 18 = 54 square feet

Answer:

mean for data set 1 is 41

data set 1 MAD is 16.4

data set 2 MAD is 16.8

mean for data set 2 is 38

Step-by-step explanation:

Finding the mean:

formula: sum of the data set / total number of terms

sum of the data set: 18 + 29 + 35 + 58 + 65 = 205

total number of terms: there is 5 numbers in the data set

mean = 205 / 5

mean = 41

MAD (Mean Absolute Value):

step 1: Find the mean of the data (above)

step 2: Find the distance between each data and mean.

18, 29, 35, 58, 65

Distance between 18 and 41 is 23 (41 - 18 = 23)

Distance between 29 and 41 is 12 (41 - 29 = 12)

Distance between 35 and 41 is 6 (41 - 35 = 6)

Distance between 58 and 41 is -17 (41 - 58 = -17)

Distance between 65 and 41 is -24 (41 - 65 = -24)

step 3: take the absolute value of any negative numbers

|-17| and |-24| is 17 and 24

step 4: add all the distances

23 + 12 + 6 + 17 + 24 = 82

step 5: divided it by the number of data

82 / 5 = 16.4

formula: sum of the data set / total number of terms

sum of the data set: 19 + 26 + 27 + 45 + 73 = 190

total number of terms: there is 5 numbers in the data set

mean = 190 / 5

mean = 38

MAD (Mean Absolute Value):

step 1: Find the mean of the data (above)

step 2: Find the distance between each data and mean.

19, 26, 27, 45, 73

Distance between 19 and 38 is 19 (38 - 19 = 19)

Distance between 26 and 38 is 12 (38 - 26 = 12)

Distance between 27 and 38 is 11 (38 - 27 = 11)

Distance between 45 and 38 is -7 (38 - 45 = -7)

Distance between 73 and 38 is -35 (38 - 73 = -35)

step 3: take the absolute value of any negative numbers

|-7| and |-35| is 7 and 35

step 4: add all the distances

19 + 11 + 12 + 7 + 35 = 84

step 5: divided it by the number of data

84 / 5 = 16.8

Person A leaves his home to visit his cousin, person B, who lives 263 miles away. He travels at an average rate 46 miles per hou

gladu [14]

Answer:

It will take 2 hours after person B leaves before they meet

Step-by-step explanation:

Step 1: Determine expression for calculating speed, distance and time

The expression for calculating distance, speed and time is;

d=s×t

where;

d=distance in miles

s=speed in miles per hour

t=time in hours

Step 2: Distance covered by person A after 0.5 hours

In this case;

d=unknown

s=46 miles per hour

t=0.5 hours

replacing;

d=(46×0.5)=23 miles

Step 3: Determine the remaining distance to person B house

Remainder=Total distance-distance already covered by person A

where;

total distance=263 miles

distance already covered by person A=23 miles

replacing;

Remainder=(263-23)=240 miles

Remaining distance to person B house=240 miles

Step 4: The time it will take for them to meet

The only have a distance (d) of 240 miles left to cover

Since they are moving towards the same direction, there speeds (s) are added together=(46+74)=120 miles per hour

replacing in the expression below;

time=distance/speed

time=(240/120)=2 hours

It will take 2 hours after person B leaves before they meet
