Answers

There are numerous important information's already given in the question. Based on those information's the answer to the question can be easily determined.
Number of movies that are drama = 5
Number of comedy movies = 8
Number of adventure movies = 11
Total number of movies that Jazmin has = 5 + 8 + 11
= 24
Then
Ratio of adventure movies to the total number of movies = 11:24
This ratio of 11:24 cannot be simplified further. So this is the answer to the given question. I hope the procedure is clear enough for you to understand.

The total number of movies in Jazmin's collection is:
5+ 8+ 11= 24

11 adventure movies: 24 movies

The ratio of adventure movies to the total number of movies in Jazmin's collection is 11:24~

A gardening box has a perimeter of 27 1/2 feet. if the length is 9 feet, what is the area?

Answers

42 ³/₄ ft²

Further explanation

Given:

A gardening box has a perimeter of 27 ¹/₂ feet.
The length is 9 feet.

Question:

What is the area?

The Process:

A gardening box is rectangular. Units of length that are the same, i.e., in feet.

The perimeter formula is as follows:

$\boxed{ \ Perimeter = length + length + width + width \ }$

It can also be written as follows:

$\boxed{\boxed{ \ Perimeter = 2 * (length + width) \ }}$

Step-1: calculate the width

Let's use the formula above.

$\boxed{ \ 2 * (9 + width) = 27(1)/(2) \ }$

$\boxed{ \ 9 + width = (55)/(2) / 2 \ }$

$\boxed{ \ 9 + width = (55)/(2) * (1)/(2) \ }$

$\boxed{ \ 9 + width = (55)/(4) \ }$

$\boxed{ \ width = (55)/(4) - 9 \ }$

$\boxed{ \ width = (55)/(4) - (36)/(4) \ }$

$\boxed{\boxed{ \ width = (19)/(4) \ ft\ }}$

Step-2: calculate the area

The area formula is as follows:

$\boxed{\boxed{ \ Area = length * width \ }}$

$\boxed{ \ Area = 9 * (19)/(4) \ }$

$\boxed{ \ Area = (171)/(4) = 42(3)/(4) \ }$

Thus, the area of a gardening box is $\boxed{\boxed{ \ 42(3)/(4) \ ft^2 \ }}$

Keywords: a gardening box, has a perimeter, 27 1/2 feet, the length, width, 9 feet, what is the area?, rectangular, formula

To figure out the width is easy all you do is subtract the length twice, because of there being 2 sides that have the same length,and then divide whatever is left. So its 27.5-18=9.5. 9.5/2=4.75. 4.5 is your width. and now area. area=length times width, so a= 9 times 4,75, which is 42.75.

How do you solve for x in x^2+5x=36

Answers

First we want to set the equation equal to zero by subtracting 36 from each side...

x^2 + 5x -36 = 0

Now we factor

(x + 9)(x - 4) = 0

Now set each expression equal to zero and solve...

x + 9 = 0 x - 4 = 0
x = -9 x = 4

Your solution set is

(-9, 4)

Answer: (-9,4)

Step-by-step explanation: First, we set the equation equal to zero by subtracting 36 from both sides to get x² + 5x - 36 = 0.

Next, we factor the left side of the equation

as the product of two binomials.

Since the factors of -36 that add to +5 are +9 and -4,

we have (x + 9)(x - 4) = 0.

This means that either x + 9 = 0 or x - 4 = 0.

Solving each equation from here,

we have x = -9 or x = +4.

So your solution set is (-9,4).
