Answer: You will need 1080 in²

Step-by-step explanation:

The formula for finding the area of a triangle is:

Area = 1/2 x b x h

b = base length
h = height

So the equation would be:

1/2 x 12 x 30 = 180

After finding our answer of 180 we multiply it by the amount of pennants we want to hang in this case that number is 6

180 x 6 = 1080

That's how we arrive at our answer of 1080 in².

I need help -x + 5y = 14, x + 3y = 18 solve by substitution

Answers

Answer:

x=6,y=4 equation form

or

(6,4) point form

Step-by-step explanation:

Answer: x = 6, y = 4

Step-by-Step Explanation:

=> -x + 5y = 14 (Eq. 1)
=> x + 3y = 18 (Eq. 2)

From Eq. 2,
=> x = 18 - 3y (Eq. 3)

Substitute value of ‘x’ from Eq. 3 in 1 :-

-x + 5y = 14
-(18 - 3y) + 5y = 14
-18 + 3y + 5y = 14
8y = 14 + 18 = 32
=> y = 32/8 = 4

Therefore, y = 4

Substitute value of ‘y’ in Eq. 3 :-

x = 18 - 3y
x = 18 - 3(4)
x = 18 - 12
=> x = 6

Therefore, x = 6

PLEASE HELPP ASAP Gavin has two bags of titles. The number and colors of the titles are shown in the table. If Gavin randomly draws one tile from each bag what is the probability that he will select two black tiles?

Answers

Answer:

the answer is 7/27 cause you find the total number of tiles and total number of black tile then put it in the ratio of :

total no of black tiles/ total tiles

Answer:

The answer is 7/27

Step-by-step explanation:

For this you will be using What you want over the total of what you have. Sum all the things which gives you: 27 in total.

You want only the black ones, so add 3+4 and you get 7

What you want is the black (7) over the total amount you have (27)

so your answer is 7/27

Answer:

  1/2(n -10) = -4

Step-by-step explanation:

Understanding the given sentence as a math sentence requires that you first understand it as an English sentence.

Parsing the English

The subject of the English sentence is "difference". We know that a difference in math is two values separated by a minus sign. Having understood that, we need to identify the two values involved.

The descriptor of "difference" in the English sentence is "of a number n and 10." This tells us the two values are "n" and "10". The first one listed goes on the left of the minus sign. So, the difference we're talking about is ...

  (n -10)

The English sentence tells us that this difference is multiplied by 1/2. The math equivalent is shown as ...

  [tex]\dfrac{1}{2}(n-10)[/tex]

When the English tells us the result of this operation, it means this value is equal to that result. We are told this value is equal to -4

Writing the equation

We now know the left- and right-sides of the equation being described in English. That means the equation described is ...

   [tex]\dfrac{1}{2}(n-10)=-4[/tex]

Describe how you would use unit cubes to determine the volume of the rectangular prism below. What is the volume of the rectangular prism? A cube that is five inches in length width and height.

Answers

Answer:

Unit Cubes = 125 in

Volume = 125 in

Step-by-step explanation:

To find the volume of a rectangular prism, we multiply the length of the prism by the width of the prism by the height of the prism.

Volume of rectangular prism = length x width x height

Advance explanation:

The formula to find the volume of the rectangular prism is this:

L x W x H = V

L = Length = 5 in

W = Width = 5 in

H = Height = 5 in

V = Volume = 125

You first need to multiply the Length with the Width then multiply the Length and Width with the height (5 x 5 x 5), after that your answer will be 125 In

Hope this helps!

Summarized Steps:

Multiply the Length and Width with the Height (L x W x H).Your answer will be the result of the equation.

Leena pulls a blue tile out of a bag of same-size tiles without looking. There are 4 purple tiles, 6 blue tiles, and 8 green tiles left in the bag. Find the theoretical probability that the next tile she picks is the same color and the probability that it is a different color. Is it likely the next tile she picks will match?

Answers

Answer:

1/3

Step-by-step explanation:

To find the probability of finding a blue tile you have to find blue tiles over the total number of tiles

First, we have to find the total amount of blue tiles

4 purple 6 blue 8 green

we have 6 blue tiles

Next, we have to find the the total amount of tiles

4+6+8=18

Now, we put it as a fraction then simplify

6/18=1/3
