Answers

Answer: $65.67

Step-by-step explanation:

Question does not seem complete as it lacks what exactly needs to be done.

I will however assume that it wants the final price of this pair of shoes.

The shoes cost $54.75

A 9% processing fee will be added to the cost:

= 54.75 + ( 1 + 9%)

= $59.68

Then there is a shipping fee of $5.99.

Total is:

= 59.68 + 5.99

= $65.67

Find the volume of a right circular cone that has a height of 12.7 m and a base with a circumference of 18.9 m. Round your answer to the nearest tenth of a cubic meter.

Answers

Answer:

119.64m^3

Step-by-step explanation:

Given that

The height is 12.7 m

And the base with the circumference is 18.9 m

We need to find out the volume of the right circular cone

As for determining it first compute the radius

As we know that

Circumference = 2πr

18.9 = 2 × 3.14 × r

r = 3m

Now the volume is

= 1 ÷ 3πr^2h

= 1 ÷ 3 × 3.14 × 3^2 × 12.7

= 119.64m^3

To find a y term, find the absolute value of the x term (|x|).

Absolute value - the distance between 0 and a number. The absolute value of a number will always be equal to the positive form of the number (if it isn't already positive).

Some examples: The absolute value of 18 is 18. The absolute value of -10 is 10.

Find the absolute value of each x term to find y:

x ⇒ y

-2 ⇒ 2

-1 ⇒ 1

0 ⇒ 0 (the absolute value of 0 is always 0)

1 ⇒ 1

2 ⇒ 2

Answers

should isolate y
this is a slope intercept form equation
if you were to solve it, you’d get y = 1/9x - 7/3

We will isolate the variable y to make the equation in the slope-intercept form.

And the equation is y = x/9 - 7/3.

What is linear equation?

Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.

Given:

A linear equation,

x - 9y = 21.

We will isolate the variable y to make the equation in the slope-intercept form.

9y = x - 21

∠Q ≈ 42.969, ∠P ≈ 52.03, QR ≈ 15.036

Step-by-step explanation:

Law of sines:

13/sin Q = 19/sin 85°

=> sin Q = 13 × sin 85°/19

=> Q = sin^-1 (13 × sin 85°/19)

=> Q ≈ 42.969

∠P=> 180 - 85 - 42.969 ≈ 52.03

QR/sin 52.03° = 19/sin 85°

A store sells ink jet printers and laser printers. On Monday, it sold a total of 100 printers. The store earns $40 profit for each ink jet printer sold and $55 profit for each laser printer sold. If the store's profits from printer sales were $4,600 on Monday, how many more ink jet printers were sold than laser printers?

Answers

Answer:

The store sold 20 more ink jet printers than laser printers.

Step-by-step explanation:

Since the store sold 100 printers, you can say that the result of adding up the numbers of each type of printers sold is equal to 100, which is:

x+y=100, where:

x is the number of ink jet printers sold

y is the number of laser printers sold

Also, you know the amount the profit the store gets for each type of printer and the total profit received on Monday which means that adding up the results of multiplying each type of printer for its price is equal to the total profit, which can be expressed as:

40x+55y=4,600

Now, you have two equations:

x+y=100 (1)

40x+55y=4,600 (2)

You have solve this system of equations to find the number of ink jet and laser printers that were sold. First, you have to solve for x in (1):

x=100-y (3)

Then, you have to replace (3) in (2) and solve for y:

40(100-y)+55y=4,600

4000-40y+55y=4,600

15y=600

y=600/15

y=40

Finally, you can replace the value of y in (3) to find the value of x:

x=100-40

x=60

Now that you know that the store sold 60 ink jet printers and 40 laser printers, you can find the difference between this numbers to be able to know how many more ink jet printers were sold:

60-40=20

According to this, the answer is that the store sold 20 more ink jet printers than laser printers.

Answers

The probability that Felix will spin a green and an F on the next spin is 2/45.

What is probability?

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Given, Felix spins each spinner 30 times. He

records the number of times each section is spun. Red (7), Yellow (5), Blue (10), Green (8)

Since probability distribution:

A probability distribution is a mathematical function that describes the probability of different possible values of a variable.

probability= desired outcome/ Total Outcomes

In our case,

Total outcomes = 30 *30

Desired outcome = spin a green and an F on the next spin

Since from probability distribution getting F and getting green has a likelihood of 5 and 8.

thus,

Probability  = 8 * 5/ 30 *30

probability = 2/45

therefore,  the probability that Felix will spin a green and an F on the next spin is 2/45.

Yall what is "Mei runs 66.72 miles in 6 weeks.If she runs 2 days each week,what is the average distance she runs each day?"

Answers

Answer:

5.56 miles

Step-by-step explanation:

We are told from the above question:

Mei runs 66.72 miles in 6 weeks.

She runs 2 days each week

Therefore, the total number of days she runs in 6 weeks is calculated as:

1 week = 2 days

6 weeks = x

Cross Multiply

x = 6 weeks × 2 days/1 week = 12 days

The average distance she runs each day is calculated as:

12 days = 66.72 miles

1 day = x

Cross Multiply

12 days × x = 1 day × 66.72 miles

x = 1 day × 66.72 miles/12 days

x = 5.56 miles

The average distance she runs each day is 5.56 miles.
