Hey there! I'm happy to help!

If something is symmetrical you can cut a line through it and it will be the same on both sides. If you have a perfect circle you can cut it in half and it will be the same on both sides, so it is symmetrical.

We see that W looks the same on both sides if you cut it in half at the 3. It is the same on both sides, so the answer is W.

420 inches of space in all equal length width and height

Step-by-step explanation:

Because 4+3+7 = 14 x 30

it all equals up to 420

Mr. Jones will need 420 inches of space in all equal length, width, and height.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations.

* Multiplication operation: Multiplies values on either side of the operator

For example 12*2 = 24

We have been given that the tissue box dimensions are 4, 3, and 7

If the class brought in a total of 30 boxes.

So the required space would be : (4+3+7)×30 = 14 × 30

Answer: The average difference of weights of all 48 eggs from mean eight is 0.08.

Step-by-step explanation:

The mean absolute deviation of a data interprets the mean distance between each data point and the mean.

When this distance goes larger it means data has greater variability

Given, 48 large eggs have a mean weight of 2.1 ounces and a mean absolute deviation of 0.08 ounces.

It means that the average difference of weights of all 48 eggs from mean eight is 0.08.

Answer:

C

Step-by-step explanation:

The slope is 1400. And the y intercept is 5000 because when x=0 y=5000. And if you multiply 1400 by 4 and then add 5000 you get 10,600 lbs for the weight at 4 weeks.

The slope is 1400 and the y-intercept is 5000 of the linear equation which is the correct answer would be option (C) y = 1400x + 5000; 10,600 lbs.

The slope of the line is defined as the angle of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

We have to determine the slope and y-intercept of the linear equation that models this data,

Week       Weight (lbs)

0                 5000

1                 6400

2                 7800

3                 9200

Slope  = (7800 - 6400)/(2 - 1) = 1400

There is a 1400 slope.

And since y=5000 for x=0, the y-intercept is 5000.

So the equation of a baby whale’s weight at 4 weeks is y = 1400x + 5000

Hence, the correct answer would be option (C)

Answer: The answer is that the length is square ft, and the width is  .

Step-by-step explanation:

The length and width of the wall of the barn are 18, 9

The area of rectangle is product of length and width

Given area of rectangle is 90 ft²

given length = 8 ft + 2ₓ width

l = 8 +2 w

area = l × w

90 = (8 +2 w) × w

90= 8w +2w²

2w²+ 8w -90 =0 or w²+4w - 45 =0

On solving w= 9, -5

as width cannot be negative so w= 9

l= 8+2×9

l=26

Thus the length and width of the wall of the barn are 18, 9

Answer:

17600 people.

Step-by-step explanation:

Given that The parade route will be 1 mile long (5,280 feet are in a mile) and the sidewalks are 10 feet deep.

The area of the parade route will be

5280 × 10 = 52800 ft^2

If the average person takes up 3 square feet of space, then, divide the area by 3. That is,

52800 / 3 = 17600 people.

Therefore, the estimate for the number of people who can attend the parade will be 17600 people.

Answer:

You are 11.5  feet off the floor are you in 5 minutes

You are 23  feet off the floor are you in 10 minutes

it will take 13.91 minutes to reach the ground

Step-by-step explanation:

If   you are top , height will keep decreasing as you move downward.

Given

top height 32 feet

Descending speed = -2.3 feet /minute

Here negative sign implies that height is decreasing.

concept used

distance = speed * time

How many feet off the floor are you in 5 minutes?

time = 5 minutes

distance descended = -2.3 feet /minute*5 minutes = - 11.5 feet

Hence ,

I would have moved 11.5 feet from the top.

Distance from ground will be = Top height - distance descended

Distance from ground will be = 32 - 11.5 = 20.5 feet

____________________________________________

How many feet off the floor are you in 10 minutes

distance descended = -2.3 feet /minute*10 minutes = - 23 feet

Hence ,

I would have moved 23 feet from the top.

Distance from ground will be = Top height - distance descended

Distance from ground will be = 32 - 23= 9 feet

______________________________________________

When you reach the ground distance descended will be 32 feet.

Since its a descend distance off the floor has to be taken as negative value

Thus, distance descend in this case will be -32 feet

-32 feet= -2.3 feet /minute*Time

Time = -32/-2.3 = 13. 91 minutes.

Thus, it will take 13.91 minutes to reach the ground.
