20/6 because 20 x 3 = 6 x 10 = 60. 309 is equivalent to 10/3 because 30 x 3 = 9 x 10 = 90.
40/12 is equivalent to 10/3 because 40 x 3 = 12 x 10 = 120.

If the scale factor between two similar solids is 2:5, then the ratio of their lateral areas is 4:10
Lena [83]
No.
The ratio of the areas is the ratio of the squares of the scale factor.
So it's  2^2 : 5^2  = 4:25

The results of the car race are shown below.Explain how to determine who drove the fastest.
gizmo_the_mogwai [7]

<u><em>Answer:</em></u>

Evans was the fastest


<u><em>Explanation:</em></u>

<u>The relation between velocity, time and distance is as follows:</u>

velocity = \frac{distance}{time}


<u>1- For Cutwright:</u>

We have the time = 84 minutes and the distance = 35 laps

<u>This means that:</u>

velocity = \frac{35}{84} = 0.61667 lap/minute


<u>2- For Evans:</u>

We have time = 96.6 minutes and distance = 42 laps

<u>This means that:</u>

velocity = \frac{42}{96.6} = 0.43478 lap/minute


<u>3- For Loza:</u>

We have time = 102.6 minutes and distance = 38 laps

<u>This means that:</u>

velocity = \frac{38}{102.6} = 0.37037 lap/minute


Based on the above calculations, we can note than Evans was the fastest


Hope this helps :)

I just need help with three, four, and seven. Solve the system of linear equations, and determine if the equation has one soluti
likoan [24]

3. If y=5x+9 and y=3x-2, then

5x+9=3x-2\implies2x+9=-2\implies2x=-11\implies x=-\dfrac{11}2

Then

y=5\left(-\dfrac{11}2\right)+9=-\dfrac{55}2+9=-\dfrac{37}2

(only one solution)

4. If y+2=4x, then y=4x-2. So we're told that 4x-5=4x-2 but this is impossible, because that would that for any x, we have -5 = -2. This is false, so this system has no solution.

7. "y is 6 less than 3 times x" means y=3x-6. "x is 2 more than one-third of y" means x=\dfrac13y+2. Solving the second equation for y gives y=3x-2, which would mean 3x-6=3x-2. But for the same reason as in (4), there is no solution. For any value of x, this equation gives the false conclusion that -6 = -2.
