As part of a training program for the Boston Marathon, a runner wants to build endurance by running at a rate of 12 mph for 15 min. How far will the runner travel in that time period? mi

Answers

An hour is 60 mins long. 15 mins is 1/4 of that. So 60/4=15. And since he’s running at 12 miles per hour, then 12/4=3. Which means he will travel exactly 3 miles in 15 minutes.

Rewrite the following equation in slope-intercept form.
y + 3 = }(x + 6)
Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer:

Slope-intercept form is

y = mx + b

We want to get the y by itself on one side of the equation.

0 = 18x + 6y – 2

First let's subtract 6y from both sides.

-6y = 18x – 2

Next let's divide both sides by -6.

y = (18 / -6)x - (2 / -6)

y = -3x + 1/3

...The last instructions are kind of confusing to me, but I think that is the answer you're after. :)

The area of the hardscape is 3x^2 + 13x + 4. what is the length and width of the hardscape

Answers

Answer:

[tex](3x+1)[/tex]

[tex](x+4)[/tex]

Step-by-step explanation:

Assuming that the given surface is two-dimensional, one can simply factor the given polynomial to find the dimensions of the surface.

[tex]3x^2 + 13x + 4[/tex]

Just by looking at the polynomial, it is fairly obvious that the factors are;

[tex](3x+1)(x+4)[/tex]

One can check this by distributing, multiply every term in one of the parenthesis by every term in the other. Then combine like terms,

[tex]3x^2 + 12x + x + 4\\\\3x^2 + 13x + 4[/tex]

Without further information, it is impossible to determine which is the length, and which is the width, one just knows that the dimensions of the surface are;

[tex](3x+1)\\\\(x+4)[/tex]

When dividing same numbers with different exponents (they’re both 10 so this works different than if they were different numbers) you subtract the top exponent by the bottom exponent. So 15-4=11 ultimately making the solution 10^11. Hope this helps :)
