At a rate of 4 gallons per min , how long will it take to fill a 300 gallon swimming pool

Time to fill = Total Gallons of the Pool / Fill Rate

Time to Fill = 300 gallons / 4 gallons per minute

Time to Fill = 75 minutes

If it takes 15 minutes to load 3 racks of buns jow many hours will it take to load 36vracks

zysi [14]

Write and solve an equation of ratios:

15 min 3 racks
---------- = -------------
x 36 racks

Solving this for x: 3x = (15)(36) => x = 180 minutes.

convert this into hours: 180 min 1 hr
------------ * -------------- = 3 hrs (answer)
1 60 min

A motorcycle travels 3 and 1/8 miles in 2.5 minutes. Which of the following represents the rate, to the nearest mile, at which t

bonufazy [111]

The rate would be 75 miles in 1 hour.

Set up a proportion to solve this:
3 1/8 miles in 2.5 minutes gives us the ratio 3.125/2.5.
The second ratio would be x miles in 60 minutes, or x/60.

3.125/2.5 = x/60

Cross multiply:
187.5 = 2.5x

Divide both sides by 2.5:
187.5/2.5 = 2.5x/2.5
75=x

0/35-31/35-2/35= Reduce if possible

sineoko [7]

Hi!

<em>I will write it like this to make it easier to see:</em>

<em />

$\frac{0}{35} - \frac{31}{35} - \frac{2}{35}$

Seeing this, we can right away take the $\frac{0}{35}$ away to make it easier, because 0/35 is 0. Now, we are left with:

$-\frac{31}{35} - \frac{2}{35}$

Since the denominators (the 35s) are the same, we do not have to mess with those. We simply subtract the numerators (-31 - 2) and we get -33. Therefore, your answer is :

$-\frac{33}{35}$

Hope this helps! Have a great day! :D

Determine whether the set of vectors <img src="https://tex.z-dn.net/?f=%20v_%7B1%3D%283%2C2%2C1%29%2C%20v_%7B2%7D%20%3D%28-1%2C-

Since each vector is a member of $\mathbb R^3$ , the vectors will span $\mathbb R^3$ if they form a basis for $\mathbb R^3$ , which requires that they be linearly independent of one another.

To show this, you have to establish that the only linear combination of the three vectors $c_1\mathbf v_1+c_2\mathbf v_2+c_3\mathbf v_3$ that gives the zero vector $\mathbf0$ occurs for scalars $c_1=c_2=c_3=0$ .

$c_1\begin{bmatrix}3\\2\\1\end{bmatrix}+c_2\begin{bmatrix}-1\\-2\\-4\end{bmatrix}+c_3\begin{bmatrix}1\\1\\-1\end{bmatrix}=(0,0,0)\iff\begin{bmatrix}3&-1&1\\2&-2&1\\1&-4&-1\end{bmatrix}\begin{bmatrix}c_1\\c_2\\c_3\end{bmatrix}=\begin{bmatrix}0\\0\\0\end{bmatrix}$

Solving this, you'll find that $c_1=c_2=c_3=0$ , so the vectors are indeed linearly independent, thus forming a basis for $\mathbb R^3$ and therefore they must span $\mathbb R^3$ .
