if the formula for the perimeter of a rectangle is p=2l+2w, what is the formula for w in terms of p and l
aleksklad [387]

Answer:

(p-2l)/2 = w

Step-by-step explanation:

p=2l+2w


We want to solve for w.

The first step is to subtract 2l from each side

p-2l=2l-2l+2w

p-2l=2w

Then we will divide each side by 2 to isolate w

(p-2l)/2 = 2w/2

(p-2l)/2 = w

I would tell her that her prediction is inaccurate because it isn’t guaranteed that the coin will land on both sides an equal amount of times. It’s possible that the coin could land heads up more often than it could land tails up or the other way around.

Find the value of x to the nearest tenth 10 and 35
Verdich [7]

We can use the tangent rule for this problem because the opposite x is unknown and adjacent side 10 is knwon. Since,

tan \theta= \frac{Opposite side}{Adjacent side}

tan 35=\frac{x}{10}

0.474=\frac{x}{10} Since tan 35°=0.474

0.474*10=\frac{x}{10}*10 Multiplying each sides by 10.

4.74=x

x=4.7 (Rounded to nearest tenth)
