A construction worker is looking at blueprints drawn to a 1/20 scale and notices that a wall is 0.5 feet by 0.25 feet. He claims

that the area of the actual wall should be 20 times the area that is on the blueprints. Explain if he is correct or incorrect.

Answer:

incorrect

Step-by-step explanation:

we are finding area which is squared, or we can put it in an equation, (0.5*20)*(0.25*20) or 0.5*0.25*20^2 which equals 50      but (0.5*0.25)*20 only equals 2.5    therefor he is incorrect and the correct answer would be 20^2 or 400 times the area.

hope this helps :)

A local pizzeria sold 65 pizzas yesterday. Suppose the actual number of pizzas sold today was 60. Describe
Rudik [331]
We need to find the difference first. 65 - 60 = 5. Now we must find what percent 5 is of 65. It is 7,7%. The number decreased, and so it is a 7,7% decrease.

Use the distrubutive property to simply 2(-5-7j)
prisoha [69]

<u>Answer:</u>

2(-5 - 7j) = -10 - 14j

<u>Step-by-step explanation:</u>

Using the distributive property means that we have to multiply both -5 and -7j by 2:

2(-5 - 7j)

⇒ 2 × -5  +  2 × -7j

⇒ -10 - 14j

The coordinates of three vertices of square ABCD are A(−212,112),B(−212,−3), and C(2,112).
Lady_Fox [76]

Answer:

<em>P=760</em>

Step-by-step explanation:

Three of the coordinates of the square ABCD are A(-212,112) B(-212,-3) C(2,112). The image below shows the square is not ABCD but ABDC. In fact, this is not a square, as we'll prove later.

Note the x-coordinate of A and B are the same. It means this side is parallel to the y-axis. Also, the y-coordinate of A and C are the same, meaning this side is parallel to the x-axis. The missing point D should have the same x-coordinate as C and y-coordinate as B, i.e. D=(2,-3).

This shape has sides that are parallel to both axes.

To calculate the perimeter we find the length of two sides.

The distance from A to B is the difference between their y-axis:

w=112-(-3)=115

The distance from A to C is the difference between their x-axis:

l=2-(-212)=215

It's evident this is not a square but a rectangle. The perimeter is

P=2w+2l=330+430

P=760
