Three guys rent a hotel room for the night. When they get to the hotel they pay the $30 fee, then go up to their room. Soon the

bellhop brings up their bags and gives the lawyers back $5 because the hotel was having a special discount that weekend. So the three lawyers decide to each keep one of the $5 dollars and to give the bellhop a $2 tip. However, when they sat down to tally up their expenses for the weekend they could not explain the following details:
Each one of them had originally paid $10 (towards the initial $30), then each got back $1 which meant that they each paid $9. Then they gave the bellhop a $2 tip. HOWEVER, 3 • $9 + $2 = $29.

The guys couldn't figure out what happened to the other dollar. After all, the three paid out $30 but could only account for $29.

Can you determine what happened?

1.85=0.05 times number of nickles
times 100 both sides
185=5 times number of nickels
divide both sides by 5
37=number of nickles

A square has an area of 576 great inches how long is each side of feet
bija089 [108]
The formula for the area of a square is A=s*s or A=s^2
So we can plug in the area and solve for the side
576=s^2 (square root both sides)
s=24 inches

Since one foot is 12 inches, 24 inches would be 2 feet

Hope this helps

Simplify (ignore my garbage camera quality ....)
monitta

Answer:

C. 3

Step-by-step explanation:

Given expression is:

({3^{\frac{1}{7}})^7

We know that the rules of exponents are used to solve these kind of questions.

When there is exponent on exponent like in this question 1/7 has an exponent of 7 , the exponents are multiplied.

So,

=3^{(7*\frac{1}{7} )}

The 7's will be cancelled out and remaining power will be 1

=3^1\\=3

Hence, option C is correct ..

The length of an arc of a circle is 7.34 units, and the measure of the corresponding central angle is 81 degrees. What is the ap
GuDViN [60]

Answer:

A.  5.19 units

Step-by-step explanation:

\textsf{Arc length}=2 \pi r\left(\dfrac{\theta}{360^{\circ}}\right) \quad \textsf{(where r is the radius and}\:\theta\:{\textsf{is the angle)}

Given:

  • \theta = 81°
  • Arc length = 7.34 units

Substituting given values into the equation and solving for r:

\implies 7.34=2 \pi r\left(\dfrac{81^{\circ}}{360^{\circ}}\right)

\implies 7.34=r\left(\dfrac{18 \pi}{40}\right)

\implies 7.34 \cdot 40=18 \pi r

\implies 293.6=18 \pi r

\implies r=\dfrac{293.6}{18 \pi}

\implies r=5.19 \sf \: units \:(2\:dp)
