Answer:

660,000 gallons.

Step-by-step explanation:

Quarts refers to a unit of measurement of volume of a fluid such as water. Quart is typically a standard unit in the British Imperial (imperial quarts) and United States of America (U.S) Customary systems (liquid and dry quarts) of measurement as a unit of volume or capacity.

Generally, there are three (3) types of quarts still in use today; dry quarts, imperial quarts and the liquid quarts.

A quart has the symbol "qt" and it's typically calculated as a quarter (¼) of a gallon.

Mathematically, it is given by the expression;

[tex] 1 \; Quart = 0.25 \; Gallon[/tex]

Therefore, [tex] Gallon = Quart * 0.25[/tex]

Given that the volume or capacity of the swimming pool is 2,640,000 quarts.

[tex] Gallon = 2,640,000 * 0.25[/tex]

[tex] Gallon = 660,000 [/tex]  

Hence, the gallons of water of a swimming pool holding 2,640,000 quarts of water is 660,000 gallons.

Explanation:

Imagine you randomly selected n items to form a sample, and you did this 100 times. Each time doing a trial like this, we generate a confidence interval. We expect about 99 of those times to have a confidence interval containing the true value of μ. This is what it means when we say "We are 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of μ."

Answer:  see proof below

Step-by-step explanation:

Use the following Sum to Product Identities:

[tex]\cos A+\cos B=2\cos \bigg(\dfrac{A+B}{2}\bigg)\cdot \cos \bigg(\dfrac{A-B}{2}\bigg)\\\\\\\sin A-\sin B=2\cos \bigg(\dfrac{A+B}{2}\bigg)\cdot \sin \bigg(\dfrac{A-B}{2}\bigg)[/tex]

Use Even/Odd Identities:    cos (-A) = - cos A

                                             sin (-A) =   sin (A)

Use Quotient Identity:   [tex]\cot A=\dfrac{\cos A}{\sin A}[/tex]

Proof LHS →  RHS:

[tex]\text{LHS:}\qquad \qquad \qquad \dfrac{\cos x+\cos 7x}{\sin x - \sin 7x}[/tex]

[tex]\text{Sum to Product:}\qquad \dfrac{2\cos \bigg(\dfrac{x+7x}{2}\bigg)\cdot \cos \bigg(\dfrac{x-7x}{2}\bigg)}{2\cos \bigg(\dfrac{x+7x}{2}\bigg)\cdot \sin \bigg(\dfrac{x-7x}{2}\bigg)}[/tex]

[tex]\text{Simplify:}\qquad \qquad \quad \dfrac{2\cos \bigg(\dfrac{8x}{2}\bigg)\cdot \cos \bigg(\dfrac{-6x}{2}\bigg)}{2\cos \bigg(\dfrac{8x}{2}\bigg)\cdot \sin \bigg(\dfrac{-6x}{2}\bigg)}[/tex]

                          [tex]= \dfrac{ \cos (-3x)}{\sin(-3x)}[/tex]

[tex]\text{Even Odd:}\qquad \quad \dfrac{ -\cos (3x)}{\sin(3x)}[/tex]

[tex]\text{Quotient:}\qquad \quad -\cot(3x)[/tex]

LHS = RHS  [tex]\checkmark[/tex]

Answer:

length and width are x + 6 and 5x - 7y

Step-by-step explanation:

5x² + 30x - 7xy - 42y

= 5x(x + 6) - 7y(x + 6)

= (x + 6)(5x - 7y)

so

length and width are x + 6 and 5x - 7y

Answer:

Second option from the top

Step-by-step explanation:

        First, let us simplify x + 2 < -3

x + 2 < -3

x + 2 - 2 < -3 - 2

x < -5

        Now we can more clearly see which graph is correct.

   -> Since we are using < / > and not ≤ / ≥ the dot will be opened and not closed. This rules out the first and third options.

   -> Next, we need the direction of the line. Since < is facing to the left, our line will also be going to the left.

   -> To satisfy all requirements, since all graphs start at -5 already, the correct answer is the second option from the top.

Answer:

it's the second one

Step-by-step explanation:

it's all just common knowledge

the sign is a less than sign so the sign is an open dot. That eliminated two options. And whatever way the less than sign is pointing is the way the arrow goes

Answer:

[tex]y=0.5x-3[/tex]

Step-by-step explanation:

Given the following question:

Point A = (-4, -5) = (x, y)
[tex]m=\frac{1}{2} =0.5[/tex]

To find the slope intercept form of the given information we will have to use the formula y = mx + b where m equals the slope.

[tex]y=mx+b[/tex]
[tex]-5=0.5(-4)+b[/tex]
[tex]0.5\times-4=-2[/tex]
[tex]-5=-2+b[/tex]
[tex]-2+2=0[/tex]
[tex]-5+2=-3[/tex]
[tex]b=-3[/tex]
[tex]y=0.5x-3[/tex]

Which means your answer is "y = 0.5x - 3."

Hope this helps.

Answer:

[tex]1.5x^2+6x+6[/tex]

Step-by-step explanation:

Collect 1.5 from everything, noticing that [tex]6= 1.5\times 4)[/tex]

[tex]1.5(x^2+4x + b^2)[/tex]

Now let's remember that the square of a binomial is [tex](x+b)^2 = x^2+2xb+b^2[/tex], confronting with what we have inside the bracket, [tex]2bx = 4x \implies b=2[/tex]

Our completed bynomial becomes [tex]1.5(x^2+4x+4) = 1.5x^2+6x+6[/tex]

Answer:

1.5x² + 6x + 6

Step-by-step explanation:

1.5x² + 6x + ? = a(x + b)²

a = 1.5

2ab = 6

ab = 3

b = 3/1.5

b = 2

So, inputting all the values :-

a(x + b)²

1.5(x + 2)²

1.5(x² + 4x + 4)

1.5x² + 6x + 6

Answer:

0.222

Step-by-step explanation:

the slope of a line is equal to (y2-y1)/(x2-x1)

y1= 8

y2= 6

x1=5

x2=-4

(6-8)/(-4-5)

=0.222

The number of cats that you have is; 27 cats

Let the number of cats alice has be x.

Since you have thrice the amount of cats that alice has, then you have 3x cats.

Bob has 7 less cats than you. Thus, bob has; 3x - 7

If they have a total of 56 cats, then;

x + 3x - 7 + 3x = 56

7x - 7 = 56

7x = 56 + 7

7x = 63

x = 63/7

x = 9

Thus, number of cats you have = 3x = 3 * 9 = 27 cats
