100 is the max % that there so divide 100% by 15=which is 6.66666666667 and so just multiply <span>6.66666666667*30 the cabs going to the airportwhich = 200 cabs</span>

So 15% is out of 100%, and the cab company has sent 30 cabs out of x?(x is the total number of cabs). \frac{15}{100} =  \frac{30}{x}

So, by setting up that data we already know, we can make this equation to figure out how many cabs total the company actually has:

<span>15x = 100 * 30
</span>
We do the multiplication on the right side

15x = 3000

And divide to isolate the "X" variable

x = 200

So, the cab company has 200 cabs total, and they sent out 30 of them.

makvit [3.9K]

Answer:

Step-by-step explanation:

Volume has three parameters and is three dimensional, thus needing a unit in the third power

In difference,

Area is two-dimensional and has only 2 parameters, thus needing a unit only in the second power

Points and Brainliest Giveaway!<br><br> What is the simplified form?<br> (2x^2 + 3x) + (4x^2 -7)
nika2105 [10]

Answer:

Explanation:

We can factor the numerator and denominator as;

(

x

−

2

)

(

x

−

1

)

2

x

(

x

−

1

)

We can now cancel common term in the numerator and denominator:

(

x

−

2

)

(

x

−

1

)

2

x

(

x

−

1

)

⇒

x

−

2

2

x

However, we cannot divide by

0

so we must exclude:

2

x

=

0

⇒

x

=

0

and

x

−

1

=

0

⇒

Where:

x

Or

Factor: 3x3 + 15x2 +4xy +20y
Sveta_85 [38]

Answer:

The factored version of the given equation is going to be (3x² + 4y)(x + 5)

Step-by-step explanation:

<em>3x³ + 15x² + 4xy + 20y</em>

First, you break down 3x³. You can do this by finding the common factor of 3x³ and 15x². You can add the x to the other parentheses because x times x² equals x³

<em>(3x² + )(x + 5)</em>

Now, we break down 4xy by finding the common factor of 4xy and 20y.

<em>(3x² + 4y)(x + 5)</em>

So, the factored version of the equation above is (3x² + 4y)(x + 5)
