Find each angle or arc measure.

The width and the length of the rectangular pen will be equal to w=11 feet and the length=20 feet.

The perimeter is defined as the sum of all the sides of the figure. In a rectangle, it is the sum of all the sides of the rectangle.

For this problem, we need to find what perimeter is equal to 62 feet. To find the perimeter of a rectangle we do:

P=2w+2l

where p = perimeter, w = width, and l = length

This problem says that the length is 9 feet longer than the width, so the length would be:

w+9

Now we know what the perimeter and length is, so we can put those into the equation above. This is what it will look like:

62=2w+2(w+9)

and that will solve like so:

62=2w+2w+18

62=4w+18

44=4w

w=11

Now that we know the width we can plug it into our first equation to find the length:

62=(2(11)+2l

62=22+2l

40=2l

l=20

Your width is 11 feet and your length is 20 feet.

hence the width and the length of the rectangular pen will be equal to w=11 feet and the length=20 feet.

Answer:

25 pizzas and 36 subs

Step-by-step explanation:

5x+3x=233 --> but there are 11 more subs that pizza, so 11x3 is 33

(5x+3x) +33 = 233

5x+3x= 200

8x=200

x=25

so then 5 dollars by 25 pizzas, and 36 (25+11) subs at 3 dollars = 233$

Answer:

use vertex form of parabola:

y=a%28x-h%29%5E2%2Bk....if vertex (0,7), we have

y=a%28x-0%29%5E2%2B7

y=ax%5E2%2B7......use point (3,2) to find a

2=a%2A3%5E2%2B7

2=9a%2B7

2-7=9a

-5=9a

a=-5%2F9

so, your equation is: y=-%285%2F9%29x%5E2%2B7

Step-by-step explanation:

Before we continue, note that "percent increase from 43 to 78" is the same as "the percentage increase from 43 to 78". Furthermore, we will refer to 43 as the initial value and 78 as the final value.

So what exactly are we calculating? The initial value is 43, and then a percent is used to increase the initial value to the final value of 78. We want to calculate what that percent is!

Here are step-by-step instructions showing you how to calculate the percent increase from 43 to 78.

First, we calculate the amount of increase from 43 to 78 by subtracting the initial value from the final value, like this:

78 - 43

= 35

To calculate the percent of any number, you multiply the value (n) by the percent (p) and then divide the product by 100 to get the answer, like this:

(n × p) / 100 = Answer

In our case, we know that the initial value (n) is 43 and that the answer (amount of increase) is 35 to get the final value of 78. Therefore, we fill in what we know in the equation above to get the following equation:

(43 × p) / 100 = 35

Next, we solve the equation above for percent (p) by first multiplying each side by 100 and then dividing both sides by 43 to get percent (p):

(43 × p) / 100 = 35

((43 × p) / 100) × 100 = 35 × 100

43p = 3500

43p / 43 = 3500 / 43

p = 81.3953488372093

Percent Increase ≈ 81.3953

That's all there is to it! The percentage increase from 43 to 78 is 81.3953%. In other words, if you take 81.3953% of 43 and add it to 43, then the sum will be 78.

The step-by-step instructions above were made so we could clearly explain exactly what a percent increase from 43 to 78 means. For future reference, you can use the following percent increase formula to calculate percent increases:

((f - n)/n) × 100 = p

f = Final Value

n = Initial Value

p = Percent Increase

Once again, here is the math and the answer to calculate the percent increase from 43 to 78 using the percent increase formula above:

((f - n)/n) × 100

= ((78 - 43)/43) × 100

= (35/43) × 100

= 0.813953488372093 × 100

≈ 81.3953

The experimental probability is 4/5 if they randomly selected 6 blue, 4 yellow, 2 red, 3 green, and 5 purple marbles.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

Total number of marbles = 6+4+2+3+5 = 20

Total number of marbles except yellow = 20 - 4 = 16

The experimental probability = 16/20

or

= 4/5

Thus, the experimental probability is 4/5 if they randomly selected 6 blue, 4 yellow, 2 red, 3 green, and 5 purple marbles.

The value of a will be 0.125. Then the value of a is positive then the parabola will be upward.

It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.

A parabola opening up or down has vertex (0,-4) and passes through (-12,14).

The equation of the parabola is given as

y = a(x - h)² + k

where (h, k) is the vertex of the parabola.

(h, k) = (0, -4)

Then the equation of the parabola will be

y = a(x)² - 4

The parabola is passing through (-12, 14). Then the value of a will be

   14 = a(-12)² - 4

   14 = 144a - 4

144a = 18

     a = 1/8

     a = 0.125

Then the equation of the parabola will be

y = 0.125x² - 4

If the value of a is positive then the parabola will be upward.

The z scores are approximately:

From those scores, we can say:

=====================================================

Further Explanation:

We'll need to convert each given score to a corresponding standardized z score.

The formula to use is

z = (x - mu)/sigma

where,

Let's find the z score for the Care of Magical Creatures class

z = (x - mu)/sigma

z = (3.80 - 3.75)/(0.15)

z = 0.333 approximately

Repeat this process for the Defense Against the Dark Arts score.

z = (x - mu)/sigma

z = (3.60 - 3.25)/(0.60)

z = 0.583 approximately

And for the Transfiguration class as well

z = (x - mu)/sigma

z = (3.10 - 3.20)/(0.38)

z = -0.263 approximately

The negative z score means his grade below the average, whereas earlier the other scores were above the average since he got positive z scores.

Now do the final class (Potions) to get this z score

z = (x - mu)/sigma

z = (2.50 - 2.90)/(0.75)

z = -0.533 approximately

This grade is below average as well.

----------------------------

To summarize, we have these z scores

Harry did his best in Defense Against the Dark Arts because the z score of 0.583 (approximate) is the largest of the four z scores. On the other hand, his worst grade is in Potions because -0.533 is the lowest z score.

Answer:

The answer is B, 396 square units.

Step-by-step explanation:

We can separate the figure into five individual polygons and sum up their areas to find the total surface area of the figure.

The base of the figure is 8*12 = 96.

The rectangle at the back of the figure is 8*9 = 72.

To find the area of the rectangle on top, we need to first find second side length. To do this, we use the pythagorean theorem (a^2 + b^2 = c^2) on the right triangle, so 9^2 + 12^2 = c^2 --> 225 = c^2 --> c = 15. Next, we find the area of the rectangle which is 8*15 = 120.

The area of the triangle to the side is 1/2*12*9 (9 is height because it's a right triangle) = 54, so the area of both triangles is 54*2 = 108.

Now we sum up the areas: 96 + 72 + 120 + 108 = 396

Find the volume of the wading pool

Use V = pi * r^2 * h

Givens

r = 6 feet

h = 1.5 feet

pi = 3.14

2 f^2 takes 2 minutes.

Solution

V = pr * r^2 + h

r = d/2

r = 6 / 2

r = 3 feet

Put the givens into the formula

V = 3.14 * 3 * 3  * 1.5

V = 42.39 cubic feet

Time

2 cubic feet takes 1 minutes

42.39 cubic feet takes x                  

2/42.39 = 1/x                      Cross multiply

2x =  42.39                         Divide by 2

2x/2 = 42.39/2

x = 21 rounded to the nearest whole number.
