An uber in Los Angeles charges $3.50 per mile and $2 for every person. If taxi cab ride for three people costs $20, how far did the taxi cab travel?

Answer:

[tex]-\frac{4}{3}[/tex]

Step-by-step explanation:

[tex]-3 \frac{3}{5}[/tex] ÷ [tex]2 \frac{7}{10}[/tex]

Convert both mixed numbers to an improper fraction. This can be done by multiplying the denominator by the "number" part of the mixed number, then adding the result to the numerator.

[tex]- \frac{18}{5}[/tex] ÷ [tex]\frac{27}{10}[/tex]

Now divide the fractions, to divide the fractions, one will find the reciprocal of the recond fractions, and then multiply it by the first fractions. Remember, the reciprocal of a fraction is when one switched the numerator and denominator of a fraction.

[tex]-\frac{18}{5} * \frac{10}{27}[/tex]

[tex]= -\frac{180}{135}[/tex]

Simplify;

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

Answer:

same amount at 2 months. he'd pay 140.

Step-by-step explanation:

35(month) +35(month) =70(joining fee). 70+70=140. that's two months at the first gym.

the second gym is also 140 for the two months because each month is $70. and 70+70=140

Answer:

2.5

Step-by-step explanation:

Add up all the numbers, then divide by the total amount of the numbers

1+2+3+4=10

10/4=2.5

Answer:

I think 2.5 years

Step-by-step explanation:

Since mean is the same thing as average,

I added them together

1+2+3+4 = 10

then divided by the amount of numbers there are

10÷4=2.5

Answer:

2t^2 - 37t + 171

Step-by-step explanation:

distrube the - to the (t-9) and then combine like terms

Answer:(2t2 +  27t) -  162  = 0  

STEP

2

:

Trying to factor by splitting the middle term

2.1     Factoring  2t2+27t-162  

The first term is,  2t2  its coefficient is  2 .

The middle term is,  +27t  its coefficient is  27 .

The last term, "the constant", is  -162  

Step-1 : Multiply the coefficient of the first term by the constant   2 • -162 = -324  

Step-2 : Find two factors of  -324  whose sum equals the coefficient of the middle term, which is   27 .

     -324    +    1    =    -323  

     -162    +    2    =    -160  

     -108    +    3    =    -105  

     -81    +    4    =    -77  

     -54    +    6    =    -48  

     -36    +    9    =    -27  

     -27    +    12    =    -15  

     -18    +    18    =    0  

     -12    +    27    =    15  

     -9    +    36    =    27    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -9  and  36  

                    2t2 - 9t + 36t - 162

Step-4 : Add up the first 2 terms, pulling out like factors :

                   t • (2t-9)

             Add up the last 2 terms, pulling out common factors :

                   18 • (2t-9)

Step-5 : Add up the four terms of step 4 :

                   (t+18)  •  (2t-9)

            Which is the desired factorization

Equation at the end of step

2

:

 (2t - 9) • (t + 18)  = 0  

STEP

3

Theory - Roots of a product

3.1    A product of several terms equals zero.  

When a product of two or more terms equals zero, then at least one of the terms must be zero.  

We shall now solve each term = 0 separately  

In other words, we are going to solve as many equations as there are terms in the product  

Any solution of term = 0 solves product = 0 as well.

Answer: 64=s3

Step-by-step explanation: V=s3

64=s3

find the cubic root of each side

3√ 64=s4=s

so the side of the cube is 4 cu in.

The surface area of a cube is

Answer:

[tex]30[/tex]

Step-by-step explanation:

1. Approach

First, use the Pythagorean theorem to solve for the hypotenuse of the given right triangle. Then find the perimeter by adding up the values of all the sides. The problem then has the lengths of the legs doubled. When the legs undergo a scaling factor, the hypotenuse and perimeter undergo the same scaling factor. Here, the legs are doubled, hence the hypotenuse and the perimeter are also doubled. Finally, subtract the new perimeter from the original perimeter.

2. Find the original hypotenuse

Remember the Pythagorean theorem states;

[tex]x^{2}+y^{2}=z^{2}[/tex]

Where (a) and (y) are the legs (or the sides adjacent to the right angle), and (z) is the hypotenuse or the side opposite to the right angle.

Substitute in the given value and solve,

[tex](5)^{2}+(12)^{2}=z^{2}\\\\25 + 144 = z^{2}\\\\169=z^{2}\\\\\sqrt{169}=z\\\\13=z[/tex]

3.Find the perimeter of the original triangle

To find the perimeter of a polygon, one must add up the lengths of all the sides.

[tex]5 + 12 + 13\\\\= 30[/tex]

4. Find the new perimeter

In a right triangle, when both legs undergo a scaling factor, the hypotenuse also has the same change, and the perimeter also undergoes the same change. In this case, the length of the legs is doubled, therefore, the hypotenuse and the perimeter are also doubled.

New hypotenuse; [tex]26[/tex]

New perimeter; [tex]60[/tex]

5. Find the difference

Now all that is left is to subtract the new perimeter from the original perimeter;

(New_perimeter) - (original_perimeter)

= [tex]60 - 30[/tex]

= [tex]30[/tex]

Answer:

The total number of vehicles is: x = 120

Hence, option C is correct.

Step-by-step explanation:

Total trucks that were sold in one month = 72 trucks

Let 'x' be the total number of vehicles.

Given that 60% of  the total vehicles sold were trucks.

Thus,

60% of x =  72

60/100 × x = 72

x = [72 × 100] / [60]

x = 120

Therefore, the total number of vehicles is: x = 120

Hence, option C is correct.

Answer:

C 120
