Answer:

\frac{3xr}{200}

Step-by-step explanation:

A certain NYC taxi driver has decided to start charging a rate of r cents per person per mile

rate is cents . convert it in to dollars

1 cent = 1/100 dollars

r cents =  r/100 dollars

Each people travels x miles

cost is \frac{r}{100} \cdot x

For 3 people the cost is

3\frac{r}{100} \cdot x

Discount is 50%, so we divide by 2

\frac{3\frac{r}{100} \cdot x}{2} =\frac{3xr}{200}

Anettt [7]

If you unroll the fence, you find it has a length equal to the circumference of a circle of radius 10 m and an average height of 3 m. Its two-sided area will be

... A = 2·(3 m)·(2π·(10 m)) = 120π m²

Then the amount of paint required is

... (120π m²) × (1L)/(100 m²) = 1.2π L ≈ 3.77 L

Graph the solution set.-10x≤2y
vagabundo [1.1K]

To be able to determine the graph of this inequality, we'll start rearranging the inequality putting the "y" variable at the left side of the equation.

\begin{gathered} -10x\leq2y \\ \frac{-10x}{2}\leq\frac{2y}{2} \\ -5x\leq y \\ or \\ y\ge-5x \end{gathered}

Since the inequality here is greater than or equal to, this means that the shade is above the solid line.

This equation also has a slope of -5 and y-intercept of 0.

Therefore, the graph of this equation looks like this:

16: 2r - 6 =22 <br> 17: 3g + 7 = 31<br> 18: 3f - 7 = 38
cricket20 [7]
<span>16: 2r - 6 =22 
2r = 22  + 6
2r = 28
r =28/2
r = 14

17: 3g + 7 = 31
3g = 31 - 7
3g = 24
g = 24/3
g= 8

18: 3f - 7 = 38
3f = 38 +7
3f = 45
f = 45/3
f = 15</span>

when Dallas committed to work one morning his average speed was 45 mph. On the return trip he average only 35 mph. Due to conges
defon

The required distance is 16.40 km.

This problem can be solved if we know the concept of speed, time and distance.

We know the speed=\frac{distance}{time}

To solve the problem let us assume that the total distance between the workplace and home is x km.

Given that his speed while going from home to work is 45 mph and while returning is 35 mph.

Time for the complete journey is \frac{5}{6}hr.

Now according to question;

   \frac{x}{45}+\frac{x}{35}=\frac{5}{6}

⇒\frac{7x+9x}{315}=\frac{5}{6}

⇒16x=\frac{5*315}{6}

⇒ x=\frac{5*315}{6*16}

∴ x=16.40\ km

So, the required distance is 16.40 km.
