Answer 1

Answer: Multiply the two base numbers of 5 and 6 together and you will have 30^3 as your answer.

Answer 2

Answer:

Answer:

27,000

Step-by-step explanation:

Solve exponents first according to PEMDAS:

5^3 is 5 multiplying by itself three times.

So,

5^3 = 5 x 5 x 5

5 x 5 x 5

25 x 5

= 125

Now let's find the second number:

6^3 is 6 multiplying by itself three times.

So,

6^3 = 6 x 6 x 6

6 x 6 x 6

36 x 6

= 216

Now let's multiply these two numbers:

125 x 216

= 27,000

MODELING REAL LIFE Bowling alley A charges $3.75 to rent shoes and $4 per game. Bowling alley B charges $2.50 torent shoes and $4.50 per game.
a. For what numbers of games is the total cost, including a pair of rental shoes, less at bowling alley A? at bowling alley B?
Bowling alley A:
Bowling alley B:
or more games
or
games
b. Bowling alley A increases the cost per game by $0.50. How does this affect your answer in part (a)? Explain.o

Answers

Using linear functions, it is found that:

a) The cheaper costs are given as follows:

Bowling alley A: 3 or more games.

Bowling alley B: 1 or 2 games.

b) Due to the same cost per game and higher cost for the pair of shoes, bowling alley A will never be cheaper than bowling alley B.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

For this problem, we have that:

The cost to rent shoes is the intercept.

The cost per game is the slope.

Hence the cost functions are given as follows:

A(x) = 3.75 + 4x.

B(x) = 2.5 + 4.5x.

The costs are equal when:

A(x) = B(x)

3.75 + 4x = 2.5 + 4.5x

0.5x = 1.25

x = 1.25/0.5

x = 2.5.

Hence the cheaper costs are given as follows:

Bowling alley A: 3 or more games.

Bowling alley B: 1 or 2 games.

Alley B has the lower initial cost due to the lower cost for the pair of shoes.

For item b, if we increase the cost per game by $0.50 for alley A, we have that:

A(x) = 4.5x + 3.75.

Hence:

Due to the same cost per game and higher cost for the pair of shoes, bowling alley A will never be cheaper than bowling alley B.

Find the area of segment CED given the following information:radius = 6in, area of ΔCAD = 17.18in2, and m∠CAD = 72°
Round your answer to the nearest hundredths if necessary.

Answers

Area of sector CAD = 72 / 360 x pi x 6^2 = 7.2pi = 22.6195 in^2

Therefore, area of segment CED = 22.6195 - 17.18 = 5.44 in^2

Answer: 5.43 square inches

Step-by-step explanation:

Here, the area of triangle ACD = 17.18 square inches,

And, the radius of the triangle having center A = 6 inches

The central angle of the arc CED = 72°

Hence, the area of the sector CAD = $(72)/(360)\pi (6)^2$

= $(2592\pi)/(360)$

= $(8138.88)/(360)$

= $22.608$ square inches

Since, the area of CED = The area of sector CAD - Area of triangle ACD

= 22.608 - 17.18

= 5.428 ≈ 5.43 square inches.

In which of the following stores would you pay the least amount for an item that is priced $360? Store A: Sale of 10% off and a successive discount of 10% off. Store B: Sale of 15% with no additional discount. Store C: Sale of $35 off and a successive discount of 10% off

Answers

The right answer for the question that is being asked and shown above is that: "A: Sale of 10% off and a successive discount of 10% off." The store that would let you pay the least amount for an item that is priced $360 is the Store A.

The correct answer is Store A: Sale of 10% off and a successive discount of 10% off.

Further explanation:

Discount is the reduction of amount in the cost price of any item.

The following formula for discount can be used when the rate of discount and the cost price is given.

$\boxed{{\text{Discount}}=\left( {\frac{{{\text{rate of discount}}}}{{100}}}\right)*{\text{cost price}}}$

The following formula for selling price can be used when the discount and the cost priceis given.

$\boxed{{\text{Selling price}}={\text{Cost price}}-{\text{Discount}}}$

Given:

The price of an item is $\boxed{\$360}$ .

Calculation:

Store A is allowing 10% off and then allowing a successive discount of 10%.

The first discount of an item by the use of the formula can be calculated as,

$\begin{aligned}{\text{discount}}&=\left( {\frac{{10}}{{100}}}\right)* 360\n&= 36\n\end{aligned}$

Now, the selling price after allowing the first discount is,

$\begin{aligned}{\text{Selling price}}&={\text{360}}-36\n&=324\n\end{aligned}$

The successive discount on the item can be calculated as,

$\begin{aligned}{\text{discount}}&=\left( {\frac{{10}}{{100}}}\right)*324\n&=32.4\n\end{aligned}$

Now, the selling price after allowing second discount is,

$\begin{aligned}{\text{Selling price}}&={\text{324}}-32.4\n&=291.6\n\end{aligned}$

Therefore, the amount we have to pay to Store A is $\boxed{\$291.6}$ .

Store B is giving 15% off with no additional discount.

The discount of an item by the use of the formula can be calculated as,

$\begin{aligned}{\text{discount}}&=\left( {\frac{{15}}{{100}}}\right)*360\n&=54\n\end{aligned}$

Now, the selling price after allowing discount can be calculated as,

$\begin{aligned}{\text{Selling price}}&={\text{360}}-54\n&=306\n\end{aligned}$

Therefore, the amount we have to pay to Store B is $\boxed{\$306}$ .

Store C is giving $35 off and then allowing a successive discount of 10%.

Now, the selling price after allowing first discount can be calculated as,

$\begin{aligned}{\text{Selling price}}&={\text{360}}-35\n&=325\n\end{aligned}$

The successive discount on the item can be calculated as,

$\begin{gathered}{\text{discount}}=\left( {\frac{{10}}{{100}}}\right)*325\n=32.5\n\end{gathered}$

Now, the selling price after deducting second discount can be calculated as,

$\begin{aligned}{\text{Selling price}}&={\text{325}}-32.5\n&=292.5\n\end{aligned}$

Therefore, the amount we have to pay to Store C is $\boxed{\$292.5}$ .

It can be clearly seen that if we buy an item which is priced at $360 from Store A then we have to pay least amount of $291.6.
