Jing spent 1/3 of her money on a pack of pens, 1/2 of her money on a pack of markers, and 1/8 of her money on a pack of pencils.
Reika [66]

As per the problem

Jing spent \frac{1}{3} of her money on a pack of pens.

\frac{1}{2} of her money on a pack of markers.

and \frac{1}{8} of her money on a pack of pencils.

Total fraction of money spent cab be given as below

Fraction of Money Spent =\frac{1}{3} +\frac{1}{2}+\frac{1}{8}

Take the LCD of denominator, we get LCD of (3,2,8)=24

Fraction of Money Spent =\frac{8+12+3}{24} =\frac{23}{24} \\\\

\\ \text{Hence fraction of Money Spent }=\frac{23}{24} \\ \\ \text{Fraction of Money left}=1-\frac{23}{24} \\ \\ \text{Simplify, we get}\\ \\ \text{Fraction of Money left}=\frac{24-23}{24} \\  \\ \text{Fraction of Money left}=\frac{1}{24}

You are skiing down a mountain with a vertical height of 800 feet. The distance from the top of the mountain to the base is 1600
adoni [48]

Answer:

θ  = 30^{0}

Step-by-step explanation:

Since the vertical height of the mountain is 800 feet, and the distance from the top to its base is 1600 feet. Let the angle of elevation be represented by θ, applying the required trigonometric function;

Sin θ = \frac{opposite}{hypotenuse}

Sin θ = \frac{800}{1600}

        = 0.5

θ = Sin^{-1} 0.5

θ  = 30^{0}

Thus, the angle of elevation from the base to the top of the mountain is 30^{0}.

Question 1: The Millers have hired an interior designer to decorate their family room. they want to have a 22" by 30" oil painti
____ [38]

Answer: Total molding cost is $197.20.

Step-by-step explanation:

Since we have given that

Length of oil painting frame = 22 inch

Width of oil painting frame = 30 inch

Width for molding = 4 inches

So, Length after molding would be

4+22+4 = 30 inches

Width after molding would be

4+30+4 = 38 inches

So, Perimeter of molding would be

2(L+B)\\\\=2(30+38)\\\\=2\times 68\\\\=136\ inches

Cost per inch = $1.45

So, Total molding cost would be

1.45\times 136\\\\=\$197.20

Hence, Total molding cost is $197.20.
