Distance traveled by an car is the ratio of the mileage gives by the car to the total fuel the tank holds. The millage of 6 kilometre per liter in 3 liter the cars can travel 18 kilometre.

Given information

All three cars can travel the same distance on a tank of gas.

The second car gets 6 kilometres per liter more than the first, but its tank holds 3 fewer liters than the first.

The third car gets 6 kilometres per liter less than the first, but its tank holds 6 more liters than the first.

Suppose the first car runs m. kilometre per liter. Then the second car will run (m+6) kilometre per liter and third car runs (m-3) kilometre per liter.

Suppose the first car has l liter in the tank. Then the second car has (l-3) liter and third car has (l+6) liters in her tank.

Distance traveled by an car is the ratio of the mileage gives by the car to the total fuel the tank holds.

As the distance traveled by the first car is same as the second one. Hence,

[tex]\begin{aligned}\\\dfrac{m}{l} &=\dfrac{m+6}{l-3} \\ml-3m&=ml+6l\\m&=-2l\\\end[/tex]

Let the above equation is equation 1.

As the distance traveled by the second car is same as the third one. Hence,

[tex]\begin{aligned}\\\dfrac{m-3}{l+6} &=\dfrac{m+6}{l-3} \\ml-3m+9-3l&=ml+6l+6m+36\\l+m&=-3\\\end[/tex]

Put the value of m in the above equation from equation 1,

[tex]l-2l=-3\\l=3[/tex]

[tex]m=2\times3=6[/tex]

Thus the value of the m is 6.

With the millage of 6 kilometre per liter in 3 liter the cars can travel 18 kilometre.

Answer:

the plane flies 396,000yd in 30 min

Step-by-step explanation:

450 / 2 = 225

1 mile = 1,760

225 * 1,760 = 396,000 yd

Plz mark as brainliest if this helped! Have a nice day!!!

-Lil_G

Step-by-step explanation:

450 miles = 1hour = 60mins

X miles = 30mins

cross multiply

450 × 30 = 60 × X

13500 = 60X

divide through by 60

225 = X

therefore, X = 225miles

now

1 mile= 1760 yards

225 miles = X

cross multiply

X = 1760 ×225

X = 396000 yards

It passes the vertical line test

the vertical line test is taking a vertical line and putting it anywhere on the graph, and if it passes 2 points, it fails, and since if you put the line anywhere, it only passes one point of the parabala, so it passes the line test

Answer: C

Step-by-step explanation: The easiest way to determine if a

relation is a function is to use the vertical line test.

The vertical line test tells us that if we can draw a vertical line

that intersects more than one point on the graph of a relation,

then the relation is not a function.

However, in this case, notice that there is no way to draw a

vertical line that intersects more than one point on the graph.

Therefore, this relation must be a function.

After solving the equations, the cost of parasailing will be 99.75 and the cost of surfing will be equal to 75.25.

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both.

Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

The given information in the question is,

Assume the cost of parasailing is x and the cost of surfing is y.

x + y = 175

Total number of people in Parasailing = 16 people

Total number of people in Surfing = 20 people

Total collection done by resort = $3,101

16x + 20y = 3,101

So, the equations will be,

16x+20y=3,101            (i)

x + y = 175                  (ii)

Now, multiply the equation (ii) by 16 and solve the equation,

16x+20y=3,101

16x+16y= 2,800

4y = 301

Now, find the value of y,

y = 301/4

y = 75.25

Then, the value of x will be equal to,

x + y = 175

x+75.25 =175

Solve for x:

x=175-72.25

x = 99.75

Answer:

(7,0) ---> (x = 7) and (y = 0)

Step-by-step explanation:

2x – 9y = 14

x= -6y +7     <-- (Substitute for x to above equation)

---------------------------------------------------------------------------------------------------------

2(-6y +7)– 9y = 14

-12y + 14 - 9y = 14    <-- combine like terms

-21y + 14 = 14  

        -14 = -14   <-- inverse operation on both sides

      -21y = 0     <-- Divide

          y = 0  <--- Substitute for y to get x  ↓

-------------------------------------------------------------------------------------------------------

2x – 9y = 14

2x – 9(0) = 14     <-- Substituted y from above

          2x = 14     <-- Divide

            x = 7

Kurt was on the treadmill for 42 minutes

Step-by-step explanation:

Answer:

After about 9 minutes.

Step-by-step explanation:

We can write an exponential function to model the decay of Herodium-100.

We are given that it decreases by half every minute.

The standard exponential function is given by:

[tex]f(m)=A(r)^m[/tex]

Where A is the initial amount, r is the rate, and m is the rate (in this case, in minutes).

Mathman initially has 2000 mL of Herodium-100. Therefore, A = 2000.

And since it decreases by half every minute, r = 1/2. Thus:

[tex]\displaystyle f(m)=2000\Big(\frac{1}{2}\Big)^m[/tex]

Mathman needs to rest when the Herodium-100 levels drop to 4 mL. Therefore, we can substitute 4 for f(m) and solve for m:

[tex]\displaystyle 4=2000\Big(\frac{1}{2}\Big)^m[/tex]

Solve for m. Divide both sides by 2000:

[tex]\displaystyle \frac{4}{2000}=\frac{1}{500}=\Big(\frac{1}{2}\Big)^m[/tex]

We can take the natural log of both sides:

[tex]\displaystyle \ln\Big(\frac{1}{500}\Big)=\ln\Big(\frac{1}{2}^m\Big)[/tex]

By logarithm properties:

[tex]\displaystyle \ln\Big(\frac{1}{500}\Big)=m\ln\Big(\frac{1}{2}\Big)[/tex]

Therefore:

[tex]\displaystyle m=\frac{\ln(1/500)}{\ln(1/2)}\approx 8.9657\approx 9\text{ minutes}[/tex]

Mathman will have to rest and replenish after 9 minutes.

Step-by-step explanation:

1. I can't see the first one very well.

2. Find the area of each triangle by doing 1/2 * base * height. This should give you [tex]40m^{2}[/tex]

3. The area of a trapezium is [tex]\frac{1}{2} (a+b)h[/tex] where a is the top edge, b is the bottom edge and h is the height.

We can work out the bottom edge using pythagoras - split the trapezium into 2 triangles on each side and a rectangle in the middle. This gives you the length of the bottom edge which is 2 + 2 + 2 = 6'

Work out the area by doing 1/2(2+6)4 = 16' squared.

4.Split this shape into a triangle and rectangle. We know the right hand edge of the triangle= 9-4 = 5'.

To find the bottom edge of the triangle, use tanθ=opposite/adjacent line. Therefore tan45=bottom edge of triangle/5'. tan 45=1 therefore bottom edge = 5'.

The bottom edge of triangle gives us the height; use 1/2(a+b)h to work out the area of the trapezium. 1/2(4+9)5 = 32.5' squared
