Answer:

<h2>The answer is 8 ft</h2>

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

perimeter = 40 ft

length = 12 ft

Substitute the values into the above formula and solve for the width

That's

40 = 2(12) + 2w

40 = 24 + 2w

2w = 40 - 24

2w = 16

Divide both sides by 2

We have the final answer as

Hope this helps you

Which of the following are solutions to the equation sinx cosx = (sqrt of 3)/4? Check all that apply.

Dmitriy789 [7]

$\sin x \cos x = \dfrac{\sqrt 3}{4}$

$2 \sin x \cos x = \dfrac{\sqrt 3}{2}$

$\sin 2x = \sin \frac \pi 3$

$2x = \frac \pi 3 + 2 \pi n \textrm{ or } 2x = (\pi - \frac \pi 3) + 2 \pi n \quad \textrm{integer } n$

$x = \frac \pi 6 + \pi n \textrm{ or } x = \frac \pi 3 + \pi n$

Which expression is equivalent to -0.55 – 0.47a + a?

Leto [7]

Answer:

-0.55 + 0.53a

Step-by-step explanation:

-0.55 – 0.47a + a

To find an expression equivalent to this, we must simplify the equation to a reasonable extent;

-0.55 – 0.47a + a

= -0.55 + 0.53a

= 0.53a - 0.55

The expression equivalent to the given one is -0.55 + 0.53a or 0.53a - 0.55

Answer:

umm i'm not rly sure what's going on here...but here's how i'd do it

Step-by-step explanation:

3280.84x12=39370.08 which is about 3,9370 feet.

to double check let's do an algebraic expression

1/3280.84=x/12 cross multiply

x(1)=3280.84(12) simplify

x=39370.08

hope that helped.

I WILL SELECT A BRAINIEST,LIKE AND GIVE 20 POINTS TO THE FIRST PERSON TO AWNSER MY QUESTIONS.

Cerrena [4.2K]

23.) 21 hrs at $ 11 per hr = (21 * 11) = 231....and u received 91% of ur wages...
0.91 (231) = 210.21
fraction u got : 210.21 / 231 = 0.91 = 91/100 <== I am not 100% sure on
this. I might be making this harder then it looks....u r going to get 210.31 take home pay.....or 91% which in fraction form is 91/100

26B. 17/10 = 85/ x
cross multiply
17x = 850
x = 850/17
x = 50....50 liters of oil <==

26C. 12:9...added = 21

12/21(4200) = 50400/21 = 2400 <== higher cost receives 2400
9/21(4200) = 37800/21 = 1800
