A poster is 3 inches long. it is 4 times as wide as it is long find the perimeter and area of the poster?

1 answer:

8 0

So we know that the width is 12 because 4 x 3 = 12. The formula to find the perimeter is Length + length + width + width. So you would do 3 + 3 + 12 + 12 = 30. Therefore the perimeter is 30 inches

Answer:

0.5

Step-by-step explanation:

First find the mean of the data

3+4+4+5 = 16

16/4 = 4

Find the distance of each data to the mean

4-3 = 1

5-4= 1

4-4 = 0

Now find the mean of those

1+1+0+0 = 2

2/4

MAD = 0.5

Find the value of y so that WX is perpendicular to YZ

Alexxandr [17]

step 1

Find out the slope WX

W(2,-3) and X(-4,9)

m=(9+3)/(-4-2)

m=12/-6

m=-2

step 2

Find out the slope YZ

Y(5,y) and Z(-1,1)

m=(1-y)/(-1-5)

m=(1-y)/-6

m=(y-1)/6

step 3

Remember that

If two lines are perpendicular

then

their slopes are negative reciprocal

that means

(y-1)/6=1/2 -----> because the negative reciprocal of -2 is 1/2

solve for y

2y-2=6

2y=6+2

2y=8

Someone please I just want to get done with this

marusya05 [52]

Answer:

{10, 20, 30, 40, 50, 60}

Step-by-step explanation:

The function is:

$f(x)=10x\\\{x\in \mathbb{N}|1\leq x \leq 6\}$

State that the tange of function is the set of all output values of a function. Therefore, the answer cannot be {1, 2, 3, 4, 5, 6} and $1\leq x\leq 6$ . The answer is not $10\leq y\leq 60$ because its output will always be a natural number and it's not stated in the answer, like I did above. The answer is {10, 20, 30, 40, 50, 60}

Six pyramids are shown inside of a cube. The height of the cube is h units. The lengths of the sides of the cube are b.The area

Viefleur [7K]

Step-by-step explanation:

Cubes have square faces, so the area of the base is b².

The volume of the cube is b³.

The height of each pyramid is half the height of the cube, so h = b/2. Which means b = 2h.

The cube is made of 6 square pyramids with the same base and height. Therefore, each pyramid has 1/6 the volume of the cube. So the volume of each pyramid is b³/6.
