Answer:

anything that has a numerator three times greater than its denominator. Examples: 3/1, 6/2, 9/3, 12/4, 15/5, so on.

Step-by-step explanation:

When simplifying, you divide both by the denominator and if it equals three, then the fraction is equal to three.

Answer:

[tex]S_{45}[/tex] = 9000

Step-by-step explanation:

there is a common difference between consecutive terms , that is

11 - 2 = 20 - 11 = 9

this indicates the sequence is arithmetic with nth term

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

here a₁ = 2 and d = 9 , then

[tex]S_{45}[/tex] = [tex]\frac{45}{2}[/tex] [ (2 × 2) + (44 × 9) ]

    = 22.5(4 + 396)

    = 22.5 × 400

Quaters - Q=12

Dimes - D=10

Nickels - N= 48

Step-by-step explanation:

First, notice that $6.40 = 640 cents. The corresponding linear equation and a solution is shown below in several steps:

Original equation for amount of Dimes (D):

10*D  + 25*(D+2) +5*4*(D+2) = 640

Simplified as following, resulting in the answer for D:

55*D=550

D=10

thus having the amount of Quarters:

Q=12

D.It is less than 0 because the addends have opposite signs and the positive addend is farther from zero.

Step-by-step explanation:

The given expression is :

When we subtract a larger number from a smaller number, we get a negative answer as mathematically we cannot subtract a larger number from smaller, so we subtract the numbers in standard format and out a negative sign in front of the answer.

Like this given expression will become : -519.70

Now, any negative number is smaller than zero.

Therefore, the correct answer is option D.

Answer:

  35

Step-by-step explanation:

A = PB

A = (7%)(500) = 0.07×500 = 35

35 is 7% of 500

_____

You can think of the % symbol as being a shorthand way to write /100. That is, ...

  7% = 7/100 = "seven hundredths" = 0.07

Answer:

I'm pretty sure it is 7.4% or 0.074.

0.041 = 4.1%

Step-by-step explanation:

The probability the first box has a secret decoder ring is 13/62.

The probability the second box has a secret decoder ring is 12/61.

The probability of both is:

P = (13/62) (12/61)

P ≈ 0.041

By using the definition of inverse functions, we will see that:

g(g(f(f(f(36))))) = f(36) = 25.

Two functions f(x) and g(x) are inverses if:

f( g(x) ) = x

g( f(x) ) = x

Then we can rewrite:

g(g(f(f(f(36)))))

First, we can see that:

g(f(f(f(36)))) = f(f(36))

Replacing that in our expression, we get:

g(g(f(f(f36))))) = g(f(f(36)))

And the above expression is equal to f(36), to be sure of that, let's replace:

u = f(36)

Then we can rewrite:

g(f(f(36))) = g(f(u))

And by definition, the above thing is equal to u:

g(f(u)) = u = f(36).

Finally, we conclude that:

g(g(f(f(f(36))))) = f(36) = 3*√36 + 7 = 3*6 + 7 = 25

Step-by-step explanation:

We know that,

The new surface area is approximately 12264.56 ft².

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

To solve this problem, we first need to calculate the original surface area of the complex solid.

The complex solid is composed of two rectangular prisms, one with dimensions 9.8 ft × 6.5 ft × 8.1 ft and one with dimensions 10.6 ft × 4.3 ft × 6.5 ft.

The surface area of the first rectangular prism is:

2(9.8 × 6.5) + 2(9.8 × 8.1) + 2(6.5 × 8.1) = 464.82 ft²

The surface area of the second rectangular prism is:

2(10.6 × 4.3) + 2(10.6 × 6.5) + 2(4.3 × 6.5) = 411.22 ft²

So the total original surface area of the complex solid is:

464.82 + 411.22 = 876.04 ft²

Now we need to find the new surface area, which is exactly 14 times the original surface area.

Therefore, we can write:

New surface area = 14 × original surface area

New surface area = 14 × 876.04

New surface area ≈ 12264.56 ft²

Thus,

The new surface area is approximately 12264.56 ft².
