Answer:

<em>The answer is 25 times</em>

Step-by-step explanation:

So i'm guessing the problem is Two neon lights are turned one at the same time. One blinks every 4 seconds and the other blinks every 6 seconds. In 60 seconds How many times will they blink together. If that is not the problem let me know

HELP<br> ASAP<br> 35 POINTS

By finding the distance between each pair of consecutive vertices, we could find that the perimeter is 26.8

<h3>How to find the perimeter of the figure?</h3>

To find the perimeter, we need to find the length of each side of the figure in the image.

And remember that the distance between two points (a, b) and (c, d) is:

√( (a - c)^2 + (b - d)^2 )

So we need to find the distance between each of the vertices of the figure.

The first two are (0, 3) and (4, -1). The distance between these is:

d = √( (0 - 4)^2 + (3 + 1)^2 ) = √25 = 5

The second pair is (4, -5) and (4, -1). The distance between these is:

d = √( (4 - 4)^2 + (-5 + 1)^2 ) = √16 = 4

The third pair is (4, -5) and (-5, 4). The distance between these is:

d = √( (4 + 5)^2 + (-5 - 4)^2 ) = √162 = 12.7

The last pair is (-5, 4) and (0, 3), this time the distance is:

d = √( (-5 - 0)^2 + (4 - 3)^2 ) = √26 = 5.1

The perimeter is the sum of these distances:

5 + 4 + 12.7 + 5.1 = 26.8

By finding the distance between each pair of consecutive vertices, we could find that the perimeter is 26.8

A recipe for oatmeal cookies makes 24 cookies. The recipe calls for 2 1/2 cups of flour. Penny wants to make 3/4 of the recipe.

barxatty [35]

Answer:

Penny needs $1\frac{7}{8}$ cups of flour to make 3/4 of the recipe.

The recipe will make 18 cookies.

Step-by-step explanation:

We have been given that a recipe for oatmeal cookies makes 24 cookies. Penny wants to make 3/4 of the recipe.

To find the number of cookies that will 3/4 of the recipe will make, we need to find 3/4 of 24 as shown below:

$\frac{3}{4}\text{ of recipe}=24\times \frac{3}{4}$

$\frac{3}{4}\text{ of recipe}=6\times \frac{3}{1}$

$\frac{3}{4}\text{ of recipe}=18$

Therefore, the recipe will make 18 cookies.

We are also told that recipe calls for 2 1/2 cups of flour. To find amount of flour needed for 3/4 of the recipe, we will multiply 2 1/2 cups by 3/4 as:

$\text{Cups of flour needed to make 3/4 of recipe}=2\frac{1}{2}\times \frac{3}{4}$

$\text{Cups of flour needed to make 3/4 of recipe}=\frac{5}{2}\times \frac{3}{4}$

$\text{Cups of flour needed to make 3/4 of recipe}=\frac{5\times 3}{2\times 4}$

$\text{Cups of flour needed to make 3/4 of recipe}=\frac{15}{8}$

$\text{Cups of flour needed to make 3/4 of recipe}=1\frac{7}{8}$

Therefore, Penny needs $1\frac{7}{8}$ cups of flour to make 3/4 of the recipe.
