Model  requiring  525 block and 290 blocks

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.

Answer:

it might be 48.9 but im not sure

Step-by-step explanation:

Answer:

I think D is correct answer if not then C.

Step-by-step explanation:

Answer:

"x" is the actual value of x, <measures is the measures of the angles itselfs. so insert x into the expression to find the angle measure.

Step-by-step explanation:

Answer:

90 degree

Step-by-step explanation:

total angle is the sum of x-18 and x

since the figure is forming right angle so angle is 90 degree

90=x-18 +x

x=54

Answer: points in original figure (-6, 2)

Points in final figure (6, 2)

Step-by-step explanation:

First reflect the figure over the y axis. Then you can see that y is still 2 and that d has now become positive 6

Put those values in as (6,2) for the final figure

Answer:

(1-2) LS = 288cm² TS = 378cm²

(3-4) LS = 1419.2 TS = 1673.5

(5) LS = 543 TS = 606

Step-by-step explanation:

(1-2)

7 1/2 = 7.5

7.5 x 15 = 112.5

9 x 12  ➗ 2 = 54

54 x 2 = 108

9 x 7.5 = 67 .5

(3-4)

3.14 x 81 = 254.3

(5)

9 x 15 = 135 x 2 = 270

15 x 7 = 105 x 2 = 210

9 x 7 = 63

0.25

Step-by-step explanation:

3 ÷ 12 = 0.25

5 ÷ 20 = 0.25

Hope this helps, thank you !!

Answer:

3 ÷ 12 = 0.25

5 ÷ 20 = 0.25

I think  the answer its 1.8 percent because if you subtract 15-13.2 comes out to be 1.8.

but l also think it could be 12 percent error.      

The odometer recorded [tex]13.2[/tex] miles for his last trip to the hardware store, but he knows the distance traveled is [tex]15[/tex] miles then the percent error is  [tex]12 \%[/tex] .

A percentage is a number or ratio that can be expressed as a fraction of 100. And is denoted using the percent sign, "[tex]\%[/tex]".

Percentage [tex]=\frac{Diffeerence \ in \ value}{Total \ value}[/tex]

We have,

Last trip to the hardware store [tex]=13.2[/tex] miles

Original trip to the hardware store [tex]=15[/tex] miles

So,

Using the above given formula;

Percentage error [tex]=\frac{Diffeerence \ in \ value}{Total \ value}*100[/tex]

                     [tex]=\frac{15-13.2}{15} *100[/tex]

                    [tex]=\frac{1.8}{15} *100[/tex]

                    [tex]=12 \%[/tex]

So, the Percentage error in the odometer is [tex]12 \%[/tex] which is find out using above given formula.

Hence, we can say that the odometer recorded [tex]13.2[/tex] miles for his last trip to the hardware store, but he knows the distance traveled is [tex]15[/tex] miles then the percent error is    [tex]12 \%[/tex] .
