<h3>
Answer: 60 grams</h3>
========================================================
Explanation:
m = mass
v = volume
d = density
The formula we use is
d = m/v
Multiplying both sides by v allows us to solve for m
d = m/v
d*v = m
m = d*v
Now plug in the given density (d = 4) and the given volume (v = 15) and simplify:
m = d*v
m = 4*15
m = 60 grams
Note how,
d = m/v
d = 60/15
d = 4
which helps confirm our answer
Sin 30 = 1/2
tan 45 = 1
Cosec 60 = 2 / √3 = 2√3 / 3
cot 45 = 1
Cos 60 = 1/2
sec 30 = 2 / √3 = 2√3 / 3
_______________________________
[ 1/2 + 1 - 2√3/3 ] ÷ [ 1 + 1/2 - 2√3/3 ] = <em>1</em>
The face and denominator of the fraction are exactly the same thus the answer is 1 .
<span>The answer is 7 ft. The bathroom has rectangular shape. The area (A) of a rectangle is the product of the width (w) and length (l): A = w * h. The bathroom is rectangular. We know that A = 91 ft^2 and l = 13 ft. Let's substitute them in the formula for the area: 91 ft^2 = w * 13 ft. w = 91 ft^2 : 13 ft. w = 7 ft. The width of the bathroom is 7 ft.Hope this helps. Let me know if you need additional help!</span>
