Answer:

$1.6

Step-by-step explanation:

The price of $2.32 already includes the 45% mark up hence taking the original cost to be x, it means the cost of $2.32 is 145% of the original cost

Using the concept of cross multiplication we say that if

1.45 is equivalent to $2.32

1 is equivalent to x

x=\frac {2.32}{1.45}=1.6

Therefore, the company incurs $1.6 for each plug

#17-1: Simplify this complex fraction. 1/3 / 6/9
Gnesinka [82]

\huge{\boxed{\frac{1}{2}}}

To divide by a fraction, you multiply by its reciprocal, which you find by flipping the numerator and the denominator. \frac{1}{3} \div \frac{6}{9} = \frac{1}{3} * \frac{9}{6}

Multiply the numerators and the denominators separately. \frac{1}{3} * \frac{9}{6} = \frac{1*9}{3*6} = \frac{9}{18}

Simplify by dividing both sides of the equation by 9. \frac{9 \div 9}{18 \div 9} = \boxed{\frac{1}{2}}

Serhud [2]

Answer:

The height of near by tree will be 90 feet.

Step-by-step explanation:

Considering the water triangle as shown in figure a.

As the old faithful shoots water 60 feet into the air that casts a shadow of 42 feet.

Considering the tree triangle as shown in figure a. The tree triangle has a shadow 63 feet long.

Let x be the height of near by tree that cost a shadow 63 feet long.

Assuming that the triangles are similar

So,

the ratios of similar triangles will be related as:

\frac{63}{42}=\frac{x}{60}

\mathrm{Switch\:sides}

\frac{x}{60}=\frac{63}{42}

{x}=60.\frac{63}{42}

x=90 feet

Therefore, the height of near by tree will be 90 feet.
