Answer:

w = 80/9 ft.

L = 640/9 ft.

Step-by-step explanation:

L = length w = width

2w = L/4 so 8w = L

160 = 2L + 2w

160 = 2(8w) + 2w

160 = 16w+2w

160 = 18w

80/9 = w

Hello!

<u><em>Answer:</em></u>

<u><em>w=12</em></u>

<u><em>*The answer must have a positive sign.*</em></u>

Step-by-step explanation:

First, you add by 5 from both sides of an equation.

$-5+\frac{w}{3}+5=-1+5$

Then, you simplify.

$\frac{w}{3}=4$

Next, you multiply by 3 from both sides of an equation.

$\frac{3w}{3}=4*3$

And finally, simplify and solve. You can also multiply by the numbers from left too right.

$4*3=12$

Final answer: → $w=12$

Hope this helps!

Thanks!

Have a great day!

What is the value of a over 6 plus 3 if a=48

AlexFokin [52]

Hello there!

By a over 6, I assume you mean a / 6? And by the wording, I assume 3 is outside of the fraction.

For the three outside the fraction,

(a / 6) + 3
(48 / 6) + 3
8 + 3
= 11

Answer:

UW ≈ 6.55 ≈ 7

Step-by-step explanation:

cos (35) = adjacent/hypotenuse

cos(35) = UW/VW

cos(35) = UW/8

8*cos(35) = UW

UW ≈ 6.55

Hope this helped! <3

Please help!!!! the question is in screenshot

Answer:

$-\cos nw_0t$

Step-by-step explanation:

We can use the double angle identity for sine.

$\sin (A+B)=\sin A \cos B+\sin B\cos A$

The given expresion is

$\sin (nw_0t-90)$

We apply the identity to get:

$\sin (nw_0t-90)=\sin nw_0t \cos 90-\cos nw_0t \sin 90$

We simplify to obtain;

$\sin (nw_0t-90)=\sin nw_0t (0)-\cos nw_0t (1)$

This simplifies to:

$\sin (nw_0t-90)=-\cos nw_0t$ The correct answer is D
