Toru has $80 to pay for dog grooming. The fee is $72 plus 7.25% tax.
Does he have enough money? Explain​

Answers

We have been given that Toru has $80 to pay for dog grooming. The fee is $72 plus 7.25% tax. We are asked to determine whether Toru has enough money for grooming or not.

The total charges for grooming would be $72 plus 7.25% of $72.

[tex]\text{Total charges for grooming}=\$72+\$72\times \frac{7.25}{100}[/tex]

[tex]\text{Total charges for grooming}=\$72+\$72\times0.0725[/tex]

[tex]\text{Total charges for grooming}=\$72+\$5.22[/tex]

[tex]\text{Total charges for grooming}=\$77.22[/tex]

Since total cost of grooming is $77.22 and Toru has $80 to pay for grooming, therefore, Toru has enough money for grooming.

Find the arc length of a sector with a radius of 9 feet and a central angle of 18°. Give answer in
terms of pi.

Answers

Answer:

The arc length of a sector:

[tex]A = \frac{9}{10} \pi[/tex]

Step-by-step explanation:

-The equation for finding the Arc length, would be:

[tex]Arc length = \frac{a}{360\textdegree} 2\pi r[/tex]

-Use the given radius and the central angle for the equation:

[tex]A = \frac{18\textdegree}{360\textdegree} 2\pi (9)[/tex]

-Then, solve the equation:

[tex]A = \frac{18\textdegree}{360\textdegree} \times 2\pi \times 9[/tex]

[tex]A = \frac{1}{20} \times 2\pi \times 9[/tex]

[tex]A = \frac{2}{20}\pi \times 9[/tex]

[tex]A = \frac{1}{10}\pi \times 9[/tex]

[tex]A = \frac{9}{10}\pi[/tex]

So, the arc length of a sector is [tex]\frac{9}{10} \pi[/tex] .

The question is not complete because it is not written correctly

Complete Question:

The drama club is holding auditions for five different parts in a one act play. If 9 people audition, how many ways can the roles be assigned?

a. 362,880

b. 15,120

c. 126

d. 120

Answer:

b. 15,120

Step-by-step explanation:

In other to solve the question above, we would use the formula for permutation.

This is because when assigning 5 DIFFERENT roles to 9 people, the order of assigning the roles is important. The formula for permutation, is used when order is involved.

Permutation (n, r) = nPr = n!/(n - r)!

In the above question,

n = 9 people

r = 5 different parts

9P5 = 9!/(9 - 5)!

= 9!/4! = 9×8×7×6×5×4×3×2×1/ 4×3×2×1

= 362880/ 24

= 15,120

Therefore, the number of ways that the roles can be assigned is 15,120 ways

Does the equation y = 3.0.47x represent exponential growth, exponential decay, or neither?

Answers

the answer is exponential decay!

Answer:

exponential decay

Step-by-step explanation:

exponential decay describes the process of reducing an amount by a consistent percentage rate over a period of time. It can be expressed by the formula y=a(1-b)x wherein y is the final amount, a is the original amount, b is the decay factor, and x is the amount of time that has passed.Exponential decay occurs when the amount of decrease is directly proportional to how much exists.

Sarah kept track of the points she scored during her first five basketball games in the table shown.

What must she score during game 6 to have a mean of 12 points scored per game?

A. 10
B. 12
C. 14
D. 20
E. 22

Answers

Answer:

E

Step-by-step explanation:

If you add 22 onto the sum of all the points and divide by the amount of games (6), you get 12.

The score she must get during the 6th game to have a mean of 12 point score per game is 22.

What is mean?

The mean is the average of numbers.

Mathematically, it is represented as follows;

mean = sum of terms / number of terms

Therefore, to get a mean of 12 point score per game the 6th score can be calculated as follows:

let

x = 6th score

Hence,

8 + 12 + 10 + 6 + 14 + x   / 6 = 12

50 + x / 6 = 12

cross multiply

12 × 6 = 50 + x

72 = 50 + x

72 - 50 = x

x = 22

Therefore, the score is 22.

A 15 feet tree casts a shadow that is 8 feet long. What is the distance from the tip of the tree to the tip of it's shadow?

Answers

Answer:

17 feet

Step-by-step explanation:

I used the Pythagorean theorem to answer this question.

a^2 + b^2 = c^2

15^2 + 8^2 = c^2

225 + 64 = c^2

289=c^2

c^2=289

c=√289

c=17 feet

The length of the tip of the tree to the tip of it's shadow will be;

⇒ 17 feet

What is Pythagoras theorem?

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

Given that;

A 15 feet tree casts a shadow that is 8 feet long.

Now,

Since, A 15 feet tree casts a shadow that is 8 feet long.

Hence, The length of the tip of the tree to the tip of it's shadow = x feet

So, We get by using the Pythagoras theorem;

⇒ x² = 15² + 8²

⇒ x² = 225 + 64

⇒ x² = 289

⇒ x = √289

⇒ x = 17

Thus, The length of the tip of the tree to the tip of it's shadow will be;

⇒ 17 feet

A factory sells backpacks for $40.00 each. The cost to make 1 backpack is $10.00. In addition to the cost of making backpacks, the factory has operating expenses of $12,000 per week. The factory's goal is to make a profit of at least $9,800 per week. Which inequality represents the number of backpacks, x, that need to be sold each week for the factory to meet this goal?

Answers

Answer:

The factory needs to sell 327 packbacks to make at least 9,800 per week.

Step-by-step explanation:

We know that each backpacks is sold for $40.00.

The goal is to make at least $9,800 per week. With this information we can define the inequality

[tex]40x -10x \leq 9,800[/tex]

Where [tex]x[/tex] represents backpacks. Notice that this inequality is about profits, that's why we subtract the cost from the sell price, in this case, the profid margin is $30.00 per backpack, so

[tex]30x\leq 9,800[/tex]

Solving for [tex]x[/tex]

[tex]x\leq \frac{9800}{30}\\ x \leq 326.67[/tex]

Therefore, the factory needs to sell 327 packbacks to make at least 9,800 per week.
