Need help with this math

IgorLugansk [536]

<h2>Answer: 6 gallons </h2>

First we are told that we initially had 1/3 of the tank and when 10 gallons were added we had 3/4 of the tank:

$\frac{1}{3}+10gallons=\frac{3}{4}$ (1)

$10gallons=\frac{3}{4}-\frac{1}{3}$ (2)

$1gallon=\frac{1}{24}$ (3)

This means 1 gallon is equivalent to 1/24 tank.

On the other hand if we have 3/4 of a tank and need to reach 1 tank we have to add another fraction of the tank:

$\frac{3}{4}+X=1$ (4)

$X=\frac{1}{4}$ (5)>>>>This is the fraction needed to complete 1 tank

Now we need to know <u>how much that 1/4 tank is equivalent in gallons</u>.

From (3) we know $1gallon=\frac{1}{24}$ . So, we can write the following relation to transform from fractions of a tank to gallons:

$\frac{1}{4}.\frac{1gallon}{\frac{1}{24}}=(\frac{1gallon}{4})(\frac{24}{1})$

$\frac{24}{4}gallons=6gallons$

Therefore:

<h2>6 more gallons are needed to fill the tank</h2>

The chairlift at a ski resort rises a total of 2600 feet from where it starts. The angle of elevation is about 22.3 degrees. How

Monica [59]

Answer:

6852 feet .

Step-by-step explanation:

Refer the attached figure

The chairlift at a ski resort rises a total of 2600 feet from where it starts. i.e.AB = 2600 feet

The angle of elevation is about 22.3 degrees.i.e.∠ACB= 22.3°

We are supposed to find How far do riders travel on the lift i.e.AC

In ΔABC

We will use trigonometric ratio

$Sin\theta =\frac{Perpendicular}{Hypotenuse}$

$Sin22.3^{\circ} =\frac{AB}{AC}$

$AC=\frac{2600}{Sin22.3^{\circ}}$

$AC=\frac{2600}{0.379456159529}$

$AC=6851.9$

So, riders travel 6852 feet .
