landmark on your vacation, you create a model of it using blocks.

a) Suppose you are making a model where one block represents 2 feet. About how
many blocks tall is your model of the Empire State Building? What is the scale
factor? (2 points)

b) Suppose you are making a model where one block represents 5 feet. About how
many blocks tall is your model of the Empire State Building? What is the scale
factor? (2 points)

d) Use your knowledge of scale drawings and image sizes to fill in the missing
information in the table. (3 points)

Answers

B) your model would be 290 blocks tall because 1,450/5=290.
C)reduction of the Empire State Building because you are building a model that takes blocks representative of a larger unit than what it signifies

What is scale factor ?

Scale Factor is used to scale shapes in different dimensions. In geometry, we learn about different geometrical shapes which both in two-dimension and three-dimension. The scale factor is a measure for similar figures, who look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii.

a) You have two given data available here: the actual height of the Empire State Building measuring 1,450 feet, and the height of the block measuring 2 feet. To find how many blocks stacked together would make up 1,450 feet, just divide 1,450 by 2.

Number of blocks=1,450 feet * (1 block/2 feet)

Number of blocks = 725 blocks

Therefore, you would use a model requiring 725 blocks.

The scale factor for the model is 1 block per two feet.

b) You have two given data available here: the actual height of the Empire State Building measuring 1,450 feet, and the height of the block measuring 5 feet. To find how many blocks stacked together would make up 1,450 feet, just divide 1,450 by 5.

Number of blocks=1,450 feet * (1 block/5 feet)

Number of blocks = 290 blocks

Therefore, you would use a model requiring 290 blocks.

The scale factor for the model is 1 block per five feet.

Tom has a part-time job. On Wednesday, Tom earned $20.50, and on
Thursday he earned $36.21. On Friday, Tom earned twice as much as he
did on Wednesday. How much did Tom earn altogether for the three days?

Answers

Answer:

97.71

Step-by-step explanation:

Answer: $20.50 + $36.21

Step-by-step explanation:

$20.50 (Wednesday) + $36.21 (Thursday) = $56.71 Since Tom is getting twice as much he did on Wednesday ($20.50), we'll be doing this: $20.50 x 2 (which equals 41 or $41.00) and add it to $56.71

$56.71 + $41.00 = $97.71 So, this means that Tom earned $97.71 altogether for three days

Answers

Answer:

g = -25

t = -5

d = 9

Step-by-step explanation:

its a two step equation meaning you have to reverse the formula. For example, the first problem 1/5g + 8 =3. The first thing you would want to do is to subtract 8 from 3 because since 8 started out with addition, you have to reverse it into subtraction. so 3 - 8 = -5. Next step is to get the "g" by itself. Now since 1/5g is in multiplication form, we have to reverse it to division in order for the 1/5 to cancel out and to get "g" by itself. So then finally you do -5 ÷ 1/5 = -25. g = -25. so the answer is -25.
