Answer: 36 miles per hour (mph)

We have 12 miles traveled in 1/3 of an hour

Multiply both values by 3 so that the "1/3 hr" becomes "1 hr"

12*3 = 36

(1/3)*3 = 1

So you travel 36 miles in one hour, ie your speed is 36 miles per hour.

You can use this ratio to help

12 miles : 1/3 hr

3*(12 miles) : 3*(1/3) hr

36 miles : 1 hr

bonufazy [111]

Answer:

The sum of the measures of the angles of a convex quadrilateral is 360° as a convex quadrilateral is made of two triangles. Yes, this property also holds true for a quadrilateral which is not convex. This is because any quadrilateral can be divided into two triangles.

One serving of trail mix has 67 grams of carbohydrates, which is 22% of the recommended daily amount. What is the total recommen

DaniilM [7]

For this case we propose a rule of three:

67 grams -----------> 22%

x grams --------------> 100%

Where:

The variable "x" represents the recommended amount of daily carbohydrates.

So, we have:

$x = \frac {100 * 67} {22}\\x = 304.5455$

Rounding we have the recommended amount, in grams, of carbohydrates: 305 grams

Answer:

305 grams

Which of the following shows that polynomials are closed under subtraction when polynomial x + 5 is subtracted from 3x2 + 2x − 6

Art [367]

For this case we have the following polynomials:
$P = 3x ^ 2 + 2x - 6

Q = x + 5$
By subtracting both polynomials we have:
$P - Q = (3x ^ 2 + 2x - 6) - (x + 5)
$
What we must do is subtract terms of the same degree.
We have then:
$P - Q = 3x ^ 2 + (2x - x) + (-6 - 5)

P - Q = 3x ^ 2 + x - 11$
Answer:
$3x ^ 2 + x - 11$ will be a polynomial
