The plans for a shed call for a rectangular floor with a perimeter of 294ft. The length is two times the width. Find the length
Dmitry_Shevchenko [17]
It is important to note that the perimeter is equal to 2(width) + 2(length). let's call width w and length L.

so 294 = 2w + 2L
but the length is two times the width, so L=2w.

294 = 2w + 2(2w)
294 = 2w + 4w
294 = 6w

divide both sides by 6 to solve for w.
49 = w. so our width is 49 feet.

L = 2w, so L = 2(49). L = 98.

our length is 98 feet.

Let the vector \mathbf{v}v have an initial point at (1, -2)(1,−2) and a terminal point at (0, 0)(0,0). Plot the vector \mathbf{v
ASHA 777 [7]

Given that the initial point of the vector is (1,-2) and the termination point of the vector is (0,0).

So, the tail of the vector is at point (1,-2) and the head of the vector is at (0,0). The vector, \vec{v}, has been shown in the figure.

The magnitude of the vector:

|\vec{v}|=\sqrt{(1-0)^2+(-2-0)^2}=\sqrt{1+4}=\sqrt{5}

The direction of a vector is the angle made by a vector with the positive direction of the x-axis.

From the figure, \theta = 180 \degree\tan ^{-1} \left|\frac {0-(-2)}{0-1}\right|

\theta = 180 ^{\circ} - \tan^{-1}(2) = 180 ^{\circ} - 63.43^{\circ}

\theta =116.57 ^{\circ}

Hence, the required vector having a magnitude \sqrt {5} and direction 116.57 ^{\circ} has been shown in the figure.

You buy 3 bags of takis for $2.25 each. The sales tax is 8%. what was your total after tax
AnnyKZ [126]

Answer: <u><em>$7.29</em></u>

Step-by-step explanation: First you need to multiply 3 by 2.25 because you are buying 3 bags of takis. → 3*2.25= $6.75

Then you need to turn 8%a decimal. 8 percent is 8 out of 100% thus

8/100 or .08.

You need to multiply .08 by 6.75 and then you get your answer of $7.29 for three bags of takis with a 8% tax.

Hope I helped!

Stay safe!
