Answer:

Alright, lets get started.

An actual fly is about .2 inches long.

The model fly for the movie will be 27 feet long.

Converting 27 feet into inches, it will be = inches

So, lets first find the scale factor, so

scale factor will be =

So, scale factor will be = 1620

It means from the original size, the model fly is scaled to 1620 times.

The actual fly has a wingspan of about .5 inches.

So, the model fly will have a wingspan =

So, the model fly will have a wingspan = 810 inches

Converting inches into feet,

the model fly will have a wingspan =

So, the wingspan will be 67.5 feet. : Answer

What is 54x41 using estamation

Answer: 2,000

Step-by-step explanation: To estimate the product of 54 × 41, first round each number so that each number contains only one non-zero digit.

So in this case, we will round 54 to the nearest ten and we also round 41 to the nearest 10.

To round 54 to the nearest 10, since the digit to the right of the rounding place is 4, we round down. So 54 rounds down to 50.

To round 41 to the nearest 10, the digit to the right of the rounding place, 4, tells us to round down so 41 rounds down to 40.

Now we have 50 × 40.

If we multiply these two numbers together, we get a product of 2,000.

Therefore, 54 × 41 is approximately equal to 2,000.

Answer:

Step-by-step explanation:

First you must round 54 and 41. Now you have 50×40. It would be easier to take of the 2 zeros at the end and and them on later. Now we have 5×4. This =20. Now we add the 2 zeros we took away and get 2,000. Hope that helps!

Lin took 75 boxes of carrots and 80 boxes of potatoes to the market. She sold 68 boxes of carrots and 71 boxes of potatoes. How many boxes of vegetable did she take home?

Answer: 16

Step-by-step explanation:

Given : Lin took 75 boxes of carrots and 80 boxes of potatoes to the market.

i.e. Total number of boxes of vegetables she took =

Also, she sold 68 boxes of carrots and 71 boxes of potatoes.

i.e. Total number of boxes of vegetables she sold =

Number of boxes of vegetable did she take home =

Hence, the number of boxes of vegetable did she take home = 16

16 vegetables because 75-68=7 and 80-71=9 and 9+7=16

Simplify. x + 4.7 = −9.2 A. −13.9 B. 13.9 C. −12.9 D. 12.9

Note the equal sign. What you do to one side you do to the other.

Isolate the x, subtract 4.7 from both sides

x + 4.7 = - 9.2

x + 4.7 (-4.7) = - 9.2 (-4.7)

x = -9.2 - 4.7

x = -13.9

-13.9, or A, is your answer

hope this helps

Isolate the x, subtract 4.7 from both sides

x + 4.7 = - 9.2

x + 4.7 (-4.7) = - 9.2 (-4.7)

x = -9.2 - 4.7

x = -13.9

-13.9, or A, is your answer

hope this helps
