Answer:

For 10. the answer is 0, and 150 miles (assuming the 25 is in miles per hour)

For 11. the answer is 0, and 22.5 tacos

Step-by-step explanation:

Rate of change is equal to the change y over the change in x, or in this case, the change in speed over the change in time, because the rate for both problems is "constant", there is no change in speed. To find the number of miles driven you need to multiply the time passed (6 hours) by the speed (25 mph), 6 x 25 = 150. The number of tacos eaten is times passed (9 minutes) multiplied by the speed he is eating tacos (2.5 tacos per minute), 2.5 x 9 = 22.5. Hope this helps!

Answer:

See Explanation

Step-by-step explanation:

<em>The question is incomplete as what is required of the question is not stated.</em>

<em>However, since the question is only limited to distance, a likely question could be to calculate the distance from Bayville to Colleyville.</em>

Represent the distance from Atlanta to Colleyville with AC

Represent the distance from Atlanta to Bayville with AB

Represent the distance from Bayville to Colleyville with BC

So, we have that:

$AC = 25.5\ miles$

$AB = 10\frac{2}{3}\ miles$

The relationship between AB, AC and BC is:

$AC = AB + BC$

Make BC the subject of formula:

$BC = AC - AB$

$BC = 25.5 - 10\frac{2}{3}$

Convert fraction to decimal

$BC = 25.5 - 10.7$

$BC = 14.8$

<em>Hence, the distance from Bayville to Colleyville is 14.8 miles</em>

The product of 2 √3 and 3 √12 simplified form is...

Serjik [45]

<h2>Greetings!</h2><h3>When multiplying two roots together, you can rearrange the equation so that the roots are next to each other and so are the whole numbers:</h3>

2 x 3 x $\sqrt{3}$ x $\sqrt{12}$

<h3>This means that 2 x 3 is simple, = 6,</h3><h3>But when multiplying $\sqrt{3} x \sqrt{12}$ you simply multply the two numbers and put them in a square root:</h3>

$\sqrt{3} x \sqrt{12}$ = $\sqrt{36}$

<h3>But this can be square rooted to 6, which then means that the equation is now:</h3>

2 x 3 x 6 = 36

<h3>So the simplified form is 36.</h3>
