Answer:

20x^11

Step-by-step explanation:

Why? because you mutiply the 4 nd 5 to get 20, then you multuply the x's, whihc if they have exponents, tou just add the xponents, so 6+5=11.

Answer:

20[tex]x^{11}[/tex]

Step-by-step explanation:

When you multiply exponents, you add the exponent numbers together.

4x * 5x = 20x

5 + 6 = 11

Answer:

There are 7 teams in the league

Step-by-step explanation:

Given that the number of games is given by:

[tex]G(n) = \frac{(n^2-n)}{2}[/tex]

The equation will be used to determine the number of games. As we already know, that 21 games are scheduled which means G(n) is 21 so we have to find n when G(n) is 21

Putting this mathematically

[tex]21 = \frac{n^2-n}{2}[/tex]

Multiplying equation by 2

[tex]2*21 = 2*\frac{n^2-n}{2}\\42 = n^2-n\\n^2-n-42 = 0\\n^2-7n+6n-42 = 0\\n(n-7)+6(n-7) = 0\\(n-7)(n+6)=0\\n-7 = 0 => n=7\\n+6=0 => n=-6[/tex]

As the number of teams cannot be negative, the number of teams in league are 7.

Hence,

There are 7 teams in the league

Answer:

54 monthly payments

Step-by-step explanation:

the total number of payments = 4.5 years x 12 payments per year = 54 monthly payments

each monthly payment = loan / PV annuity factor

monthly payment = $19,000 / 45.6139 = $416.54

Answer:

Step-by-step explanation:

Answer:

0.25

Step-by-step explanation:

Here, we want to find the constant of proportionality that relates total cost in dollars to number of tickets purchased

Mathematically, that will be ;

7.50/30 = 1/4 = 0.25

Kindly note we can select any pair

The ratio of both at any point in time is constant

Answer:

Both equations are same

Step-by-step explanation:

The reason why this is true is not far fetched

looking at the first equation, we have;

3-x = 4

we can also factorize the second equation to look this way

By this, we shall be having

3(4) = 3(3-x)

By the time we take out the 3 from both sides, we will have the initial equation

So what we are saying is that both equations are the same

Answer:

70

Step-by-step explanation:

Given :

The cooper family owns a luxery sedan and a compact car the fuel tank capacity for the luxury seden is 22.45 gallon and of the compact car is 8.7 gallons.

To Find :

The difference in the fuel tank of the two car.

Solution :

Capacity of sedan, S = 22.45 gallons.

Capacity of compact car, C = 8.70 gallons.

Difference in the capacity :

D = S - C

D = 22.45 - 8.70 gallons

D = 13.75 gallons

Therefore, difference in the fuel tank of the two car is 13.75 gallons.

Hence, this is the required solution.

Answer:

All terminating and repeating decimals are not rational numbers. For example, pi is a non-terminating & irrational number.

Step-by-step explanation:

The given statement "Are all terminating and repeating decimals rational numbers? Expla" is true.

Yes, all terminating and repeating decimals are rational numbers. A

rational number is defined as any number that can be expressed as a ratio of two integers, with the denominator not equal to zero.

Terminating decimals are those decimals that end after a finite number of digits.

For example, 0.75 is a terminating decimal because it ends after two digits. To show that such decimals are rational,

We can rewrite the decimal as a fraction.

0.75 can be expressed as 75/100 or simplified to 3/4.

Since both the numerator and denominator are integers, 0.75 is a rational number.

Now

Repeating decimals are those decimals that have a repeating pattern of digits after the decimal point.

For example, 0.3333... is a repeating decimal because the digit 3 repeats infinitely.

To show that repeating decimals are rational, we can use a similar approach to terminating decimals.

Take 0.3333... as an example.

We can represent this decimal as an infinite series:

0.3333... = 3/10¹ + 3/10² + 3/10³+ ...

This can be simplified using the formula for the sum of an infinite geometric series:

0.3333... = 3/10¹ + 3/10² + 3/10³+ ...

               = (3/10)/( 1 - 1/10)               (by sum of infinite geometric serires)

               = 3/9

Since 3/9 can be simplified to 1/3, we can conclude that 0.3333... is a rational number.

Thus, all terminating and repeating decimals are rational numbers because they can be expressed as a ratio of two integers.

Step-by-step explanation:

the square root of 1/4 is 0.5 which is positive, rational, and between 0 and 1

Answer:

The answer is sqaure root of 1/4

Step-by-step explanation:

Your Welcome Plz Mark Brainliest. I got this because the sqaure root of 1/4 is 0.5 which is bewteen 1 and 0 and it is positive and rational! If you are wondering how to get the sqaure root then here is the steps

1. Simple deduction 1/4 in 1 to the power of 2 and 2 to the power of 2

2.We can simplfy this to 1/2 to the power of 2

3. This will equal 1/2 which is also equal to 0.5

Plz condsierdate giving Brainliest Thanks :)

Answer:

[tex]y=-\frac{1}{4}x+\frac{9}4}[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

(x₁ , y₁) = (3, -3) & (x₂ , y₂) = (1 , 2)

[tex]slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]

        [tex]= \frac{2-3}{1-[-3]}\\\\= \frac{-1}{1+3}\\\\=\frac{-1}{4}[/tex]

m = (-1/4)

y - y₁ = m(x - x₁)

[tex]y - 3 = \frac{-1}{4}(x - [-3])\\\\y - 3 = \frac{-1}{4} (x + 3)\\\\y - 3 = \frac{-1}{4}x-\frac{3}{4}\\\\ y = \frac{-1}{4}x-\frac{3}{4} + 3\\\\ y =\frac{-1}{4}x+\frac{-3+12}{4}\\\\ y =\frac{-1}{4}x+\frac{9}{4}[/tex]

Answer:

105 frames

Step-by-step explanation:

Given that:

At 0 seconds, the video had already played 190 frames and there are 25 frames being played per second.

When the time is equal to [tex]3 \dfrac{2}{5}[/tex], the number of frames that are already being played is:

[tex]= 3 \dfrac{2}{5} \times 25[/tex]

[tex]= \dfrac{17}{5} \times 25[/tex]

= 17 × 5

= 85 frames.

But recall that, the frames had already played 190 frames at 0 seconds, then the number of frames that had already been played when the time is equal to [tex]3 \dfrac{2}{5}[/tex] is;

=(190 - 85) frames

= 105 frames

Answer:

2 m

Step-by-step explanation:

The length and width of a rectangular garden is 10 m and 3 m respectively.

He will double the area of the garden by adding the same number of meters to both the length and the width. Area = 2(10 × 3) = 60 m².

Let x is amount of increase in the length and width such that area will be :

(10+x)(3+x) =60

30+10x+3x+x² = 60

x²+13x-30=0

x²+15x-2x-30=0

x(x+15)-2(x+15)=0

x=2 and x = -15

Neglecting negative value, he aded 2 m toboth length and width of the garden.

Answer:

1208.9

Step-by-step explanation:

To figure out the answer we have to separate it two parts

So the surface area of the piñata is

=The surface area of first cone + the area of the second second cone

=π×r×(r+s)+π×r×(r+s)

=3.14×7×(7+24)+3.14×7×(7+17)

=3.14×7×31+3.14×7×24

=681.38+527.52

=1208.9
