Nutka1998 [239]

Perimeter of a rectangle: 2(l + w)

2(l + w) ≥ 30 in


Simplify- divide both sides by 2.

l + w ≥ 15 in

Substitute (w + 3) into l so only 1 variable is used.

(w + 3) + w ≥ 15 in

Simplify further- add variables and subtract 3 from both sides.

2w ≥ 12 in

Divide both sides by 2.

w ≥ 6 in

icang [17]

ANSWER:

2.33 foot

STEP-BY-STEP EXPLANATION:

We can calculate the distance from the staircase to the wall, by means of the trigonometric cosine ratio, which is the following:

$\begin{gathered} \cos \theta=\frac{\text{ adjacent}}{\text{ hypotenuse}} \\ \theta=75\text{\degree} \\ \text{ hypotenuse = 9 foot} \\ \text{adjacent = x} \end{gathered}$

Replacing and solving for x:

$\begin{gathered} \cos 75=\frac{x}{9} \\ x=9\cdot\cos 75 \\ x=2.33 \end{gathered}$

The distance would be 2.33 foot

Helpp pls????????????

Jet001 [13]

Answer:

It just means that it is not equal to each other so the equation is false.

Step-by-step explanation:

The equal sign with a line through it means that they aren't the same. -12 is a different number from 12 so they can't end up being the same in the end of the equation.

Hope this helps!

Expression is equivalent to 486 – 9 + 6 + 33 × 2

mojhsa [17]

Answer:

549

Step-by-step explanation:

A calculator can give you an equivalent expression.

I might work from the middle outward:

= 486 -3 +33×2

= 483 +66

= (480 +60) + (3 +6)

= 540 + 9

= 549
