A pair of shoes originally costs $60. They are on sale for 25% off and sales tax is 7%. Cost is calculated by first applying the discount, then sales tax.

What is the total cost of shoes including tax?​

Answer:

Step-by-step explanation:

The domain, the possible values of x, is only limited in this function when the function is undefined. Specifically division by zero is undefined. In this case x cannot be equal to 9 because that would lead to division by zero. And that is the only restriction. So the domain is all real numbers except 9. In interval notation this is

x=(-oo, 9),(9, +oo)

Answer:

81

Step-by-step explanation:

thus it said 27 km/hr, she travel 27 km every hour so 27*3=81

Answer:

The ratio of red to blue would be 60: 6 which can be simplified to 10:1.

The ratio of red to blue counters would be 60: 6 which can be simplified to 10:1

Ratio is the comparison of two quantities in terms of same units.

Example : If a & b be two numbers, then the ratio is a/b, where b≠0

Let Blue counters = x

Red counters would be = 3 times of blue counters = 3x

There are a total of 120 counters in a box.

First we have to find, the number of red and the number of blue counters:

3x + x = 120

⇒ 4x = 120

⇒ x = 120/4

⇒ x = 30

There are 30 blue counters.

Red counters = 3×30 = 90

Carl took 1/3 of the red, 90 / 3 = 30, so there were 60 red counters left in the box.

Kerry took 80% of the blue, 30 * 0.80 = 24, so there were 6 blue counters left in the box.

The ratio of red to blue counters would be 60: 6 which can be simplified to 10:1.

Answer: D

(5/4) (1/6) 4^ (5/6)

Step-by-step explanation: I’m taking the test for this unit and I got it wrong but this was the CORRECT answer.

The probability that exactly 4 of the 5 dice land showing a "1" if, Tomer is playing a game that involves rolling 5 6-sided dice at once is 5 / 4 × (1 / 6)⁴ × (5 / 6), so option D is correct.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a value between 0 and 1.

Given:

Tomer is playing a game that involves rolling 5 6-sided dice at once,

Calculate the probability that exactly 4 of the 5 dice land showing a "1" as shown below,

Probability = 5 / 4 (1 / 6)⁴ × (5 / 6)⁵⁻⁴

Probability = 5 / 4 × (1 / 6)⁴ × (5 / 6)¹

Probability = 5 / 4 × (1 / 6)⁴ × (5 / 6)

Thus, the probability that exactly 4 of the 5 dice land showing a "1" is 5 / 4 × (1 / 6)⁴ × (5 / 6).

Step-by-step explanation:

Find the mean by adding together all of the numbers, then dividing it by how many numbers there are.

(29 + 75 + 21 + 45 + 39 + 14) / 6

= 37.17

So, if 29 is added, the mean is approximately 37.17

Answer:

D

Step-by-step explanation:

Answer: D

The first option is incorrect because 56+angle 3=180 and when you solve it angle 3 equals 124 degrees, not 142 degrees

The second option is incorrect because 56+43+angle 1=180 (because all triangles add up to 180 degrees). When you solve that angle 1 equals 81 degrees, not 99 degrees

The third option is incorrect because angle 1+angle 2=180, and we already know angle 1 equals 81, so when you solve that angle 2 equals 99 degrees, not 137 degrees. So we know the last option is correct.

But if you want to make sure it's correct, you can always solve for angle 4. Angle 4+43=180 degrees, and when you solve it, angle 4 equals 137 degrees, and we know that option is correct.
