Write two equivalent fractions for 10 to 3

1 answer:

7 0

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.

I think it's A because 35n is independent from the 50.

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]

Answer:

Evans was the fastest

Explanation:

The relation between velocity, time and distance is as follows:

$velocity = \frac{distance}{time}$

1- For Cutwright:

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

This means that:

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

2- For Evans:

We have time = 96.6 minutes and distance = 42 laps

This means that:

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

3- For Loza:

We have time = 102.6 minutes and distance = 38 laps

This means that:

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 :)

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.
