The Empire State Building is just over 1,450 feet tall. In anticipation of visiting this 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?

Answer:

725, 1 per every 2 ft.

Step-by-step explanation:

It gives the actual height for the building, 1,450, and it says one block is two feet. Divide 1,450 by 2 and you'd get 725. And we already know dat one block is two feet so it's 1:2

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.

Compare. Write &lt;,&gt;,or=<br>2/6. 2/4​
Misha Larkins [42]

Answer:

2/6<2/4

Step-by-step explanation:

We can start by simplifying the two fractions. 2/6=1/3 and 2/4=1/2. 1/3<1/2 so 2/6 is smaller than 2/4.

Ahmad just bought a used sailboat with two sails that need replacing. How much sail fabric will Ahmad need if he replaces sail A
ValentinkaMS [17]

Answer:

sail a = 81ft²

sail b base = 12ft

Step-by-step explanation:

question 5:

the measurements for sail A are 18ft(height) and 9ft (base)

the formula to find the the area of a triangle is (b · h) 1/2

(9 · 18) 1/2 = (162) 1/2 = 81

so ahmad will need 81ft² of fabric for sail a

question 6:

we know that the formula to find the area of a triangle is  (b · h) 1/2 = a, since we know the height and the area of the triangle we plug them into the equation to find the measurement of the base.  

(b · 18) 1/2 = 108

\frac{(b . 18) 1/2}{1/2} = 108/ 1/2

(b · 18) = 216

18b  = 216

18b/18 = 216/18

b= 12

check your work:

(12 · 18) 1/2 = 108

(216) 1/2 = 108

108 = 108  true!

the base measurement for sail b is 12ft

hope this helps and have a great day!!

Can anyone show me how I would figure this problem out
jeka57 [31]

The value of x is the number inside the parenthesis, so h(-4) gives x a value of -4.

The equation says when X is ≤ -4 use the first equation


So h(-4) = -1/2(x) -15

= -1/2(-4) -15

= 2 -15

= -13


When x = -2 (h(-2) ) use the 2nd equation:

h(-2) = 20-3x^2

=20-3(-2)^2

= 20-3(4)

=20-12

=8


Now you have -13 + 3(8)

= -13 + 24

=11


The answer should be 11
