Step-by-step explanation:

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

The height of the container in meters is 2.0066.

Unitary method is a mathematical way of first determining the value of a single unit then deriving the given unit from it.

According to the given question containers for international shipments measures 6 feet and 7 inches.

We know 1 feet is 12 inches.

∴ 6 feet is (12 × 6) = 72 inches.

So, 6 feet 7 inches is (72 + 7) inches which is 79 inches.

We know 1 inches is 0.0254 meter.

∴ 79 inches is ( 79 × 0.0254 ) meter which is

Answer:

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.

1/7×2/3=2/21

Solution with Steps

1/7×2/3=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

1×2 and 7×3=2/21

This fraction cannot be reduced.

Therefore:

1/7×2/3=2/21

Solution by Formulas

Apply the fractions formula for multiplication, to

1/7×2/3

and solve

1×2 and 7×3

=2/21

Answer:

1/7 × 2/3 is 2/21

becuase, if you times the numerators, which are the top numbers; and then the denominators which are the bottom numbers; like if you multiply 1×2 you get 2 and 7×3 is 21.

Step-by-step explanation:

The distance is:

Return trip will take:

The maxima of f(x) occur at its critical points, where f '(x) is zero or undefined. We're given f '(x) is continuous, so we only care about the first case. Looking at the plot, we see that f '(x) = 0 when x = -4, x = 0, and x = 5.

Notice that f '(x) ≥ 0 for all x in the interval [0, 5]. This means f(x) is strictly increasing, and so the absolute maximum of f(x) over [0, 5] occurs at x = 5.

By the fundamental theorem of calculus,

[tex]\displaystyle f(5) = f(0) + \int_0^5 f'(x) \, dx[/tex]

The definite integral corresponds to the area of a trapezoid with height 2 and "bases" of length 5 and 2, so

[tex]\displaystyle \int_0^5 f'(x) \, dx = \frac{5+2}2 \times 2 = 7[/tex]

[tex]\implies \max\{f(x) \mid 0\le x \le5\} = f(5) = f(0) + 7 = \boxed{13}[/tex]

Answer:

Step-by-step explanation:

5x² + 30x - 7xy - 42y

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

Answer:  see proof below

Step-by-step explanation:

Use the following Sum to Product Identities:

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

                                             sin (-A) =   sin (A)

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

Answer:

  √53 ≈ 7.3 miles

Step-by-step explanation:

The Pythagorean theorem can be used to find the length of a diagonal of a rectangle. The diagonal is effectively the hypotenuse of a right triangle with leg lengths equal to the side lengths of the rectangle.

__

If c represents the distance between opposite corners, and 'a' and 'b' represent the length and width of the city, then we have ...

  c² = a² +b²

  c² = 2² +7² = 53

  c = √53 . . . . . exact corner-corner distance in miles

  c ≈ 7.3 . . . . . . approximate corner-corner distance

The exact distance is √53 miles; to the nearest tenth, the distance is approximately 7.3 miles.

3) 6m+5n-m --> 6(5)+5(3)-(5)

                          30+15-5 --> 45-5 --> 40

5) 4(x+4)+2

   4x + 16 +2

   4x +18

Answer:

3)

Given:

m = 5

n = 3

We plug in these values into our equation (6m + 5n - m);

6m + 5n - m

Now modified, would be:

6(5) + 5(3) - 5

30 + 15 - 5

45 - 5

= 40

5)

If we simplify this expression,

4(x + 4) + 2

We use the distributive property to multiply 4 to both x and 4 which are in the brackets.

Which will now be;

4x + 16 + 2

Now we combine like terms (our constants):

(16 + 2) = 18

So it would be, now:-

4x + 18, C is your answer.
