Answer:

288

Step-by-step explanation:

First Divide 180/5=36. So then do 3 times 36=108. (108=People Singing, 180=People not singing). So add 108+180 to get 288.

The total number of people who attend the concert is 288.

Given that, for every 3 people at the concert singing along, there are 5 people not singing along.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Ratio of the number of people singing along at the concert to the number of people not singing along

= 3:5

Now, 3+5=8

The number of more people not singing along = 180

Let the total number of people be x

So, 5/8 × x=180

⇒ x=(180×8)/5

⇒ x=36×8

⇒ x=288

Therefore, the total number of people who attend the concert is 288.

8 lots of 8

Answer:

I know that 1 and 3 are correct.

Step-by-step explanation:

3x16+8x8

There are 8 childrens tickets, which each cost 8 dollars so you multiply those.

There are three adult tickets, which each cost 16 dollars so you multiply those and then you add the two products together.

3x16+8²

8 squared is just 8x8.

There are three adult tickets, which each cost 16 dollars so you multiply those and then you add the two products together.

Answer:

x = 2

Step-by-step explanation:

7(3x + 5) - x = 75

1. Distributive property

multiply 7 by whatever is in the parenthesis

7*3x + 7*5 - x = 75

21x + 35 - x = 75

2. Combine like terms

21x - x = 20x

20x + 35 = 75

3. Subtract 35 on both sides

20x + 35 - 35 = 75 - 35

20x = 40

4. Divide both sides by 20 since u want to isolate the variable

20x/20 = 40/20

x = 2

And thats ur answer

Answer:

i belive its d or c

Step-by-step explanation:

Step-by-step explanation:

Notice that:

1st column = (5 - 1)² = 16

2nd column = (11 - 4)² = 49

Therefore 3rd column = (18 - *)² = 121, * = 7.

Answer:

7 is the missing number

Step-by-step explanation:

Let the missing number be x.

Lets study the pattern of the numbers. In each column , we find that the bottom number is the square of the difference of first 2 numbers.

In 1st column ,

Difference of first 2 numbers = 5 - 1 = 4

The bottom number = 16 = 4²

In 2nd column ,

Difference of first 2 numbers = 11 - 4 = 7

The bottom number = 49 = 7²

Similarly ,

Difference of first 2 numbers = 18 - x

The bottom number = 121

[tex] = > {(18 - x)}^{2} = 121[/tex]

[tex] = > {(18 - x)}^{2} = {11}^{2} [/tex]

[tex] = > 18 - x = 11[/tex]

[tex] = > x = 18 - 11 = 7[/tex]

Answer:

f(11) = 9

Step-by-step explanation:

f(x) = 1/4(5-x)^2

Area of triangle = 20 square yards

Step-by-step explanation:

The height of triangle = 5 yd

The base of triangle = 8 yd

We need to find area of triangle.

The formula used is: [tex]Area\: of\: triangle=\frac{1}{2}\times base \times height[/tex]

Putting values and finding area

[tex]Area\: of\: triangle=\frac{1}{2}\times base \times height\\Area\: of\: triangle=\frac{1}{2}\times 8 \times 5\\Area\: of\: triangle=4 \times 5\\Area\: of\: triangle=20\:square\:yards[/tex]

So, Area of triangle = 20 square yards

Answer:

100°

Step-by-step explanation:

I'm sorry, I don't quite remember the name of the four sided shape when it fits into a circle but when it does, the opposite angles are equal to 180° therefore we say 180° - 80° and get 100° for the opposite angle which is U

Step-by-step explanation:

Answer:

A. 1,876 tissue holders

Step-by-step explanation:

Answer:

See below.

Step-by-step explanation:

The question tells us that 2.54 cm is equivalent to 1 inch. The next part wants to know what 5.08 cm is in inches. We can just divide 5.08 by 2.54 to figure that out.

5.08/2.54 = 2

This means that 5.08 cm is 2 inches.

The next one wants to know how many centimeters 10 inches is. We can 2.54 and multiply it by 10.

2.54 · 10 = 25.4

This means that 25.4 cm is 10 inches.

Answer:

the tree would be 45 feet tall

Step-by-step explanation:

so the house is 30 feet and 50 feet shadow, if you divide by 2 you can see that every 15 feet gives a 25 foot shadow, since 75-50 is 25 so in turn if the tree is 45 feet tall, it will make 75 foot shadow

The value of x is 20.

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

Sin 30 = 10 / x ______(10

We know that,

Sin 30 = 1/2 _____(2)

So,

Substituting (2) in (1).

1/2 = 10/x

x = 10 x 2

x = 20

Thus,

The value of x is 20.
