If 100 pencils can be sold for $90, then how many pencils are needed to earn $8500?

ira [324]

Step-by-step explanation:

You can set up a proportion.

Let x be the number of pencils needed.

$\frac{100}{90} = \frac{x}{8500}$

Solve for x.

x = 9444.44 pencils (round it up to 9445 pencils if you need a whole number)

romanna [79]

Answer:

The gallons of gas the tank contain now is <u>35 1/12</u>.

Step-by-step explanation:

Given:

Fuel tank contains 1 3/4 gallons of gasoline.

Casey adds 33 1/3 gallons of gasoline to the tank.

Now, to find the total gallons of gas the tank contain.

Converting the mixed fractions into improper.

Gallons of gasoline in fuel tank $=1\frac{3}{4}=\frac{7}{4}$ .

Gallons of gasoline Casey adds $=33\frac{1}{3} =\frac{100}{3}$ .

<u>According to question:</u>

By adding we get the total gallons of gasoline now tank contain:

$\frac{7}{4} +\frac{100}{3}$

$=\frac{7\times 3+100\times 4}{12}$

$=\frac{21+400}{12}$

$=\frac{421}{12}$

$=35\frac{1}{12}$

Therefore, the gallons of gas the tank contain now is 35 1/12.

What is sin -1(1/2) if the terminal side of 0 is located in quadrant 1.

kotykmax [81]

Answer:

Step-by-step explanation:

$\sin^{-1}(\theta)$ is going to output a number in between $\frac{-\pi}{2}$ and $\frac{\pi}{2}$ .

Luckily you are looking for $\theta$ in the 1st quadrant which is contained in the given interval above, so the answer just comes down to what the calculator returns from entering $\sin^{-1}(\frac{1}{2})$ in your calculator.

You may also use the unit circle. sine value refers to the y-coordinate on there.

So you are looking for when the y-coordinate is 1/2 in the fist quadrant which is at 30 degrees.
