Kenji scores 23 points per coin. After collecting a total of 2 coins, how many points will Kenji have scored in all?

Answer:

2/3 + 4/5

√3 - √3 ( = 0)

√49 - √1

Step-by-step explanation:

Expressions representing a rational numbers are B , D and E

A number that can be expressed as an integer or the quotient of an integer divided by a nonzero integer.

Irrational number, any real number that cannot be expressed as the quotient of two integers.

Firstly, we know that π is an irrational number .

So π x √4 = 2π

2π is an irrational number and so option A cannot represent a rational number.

2/3 + 4/3 = 6/3 = 2

[tex]\sqrt{36} + \sqrt{5}[/tex]

= 6 + [tex]\sqrt{5}[/tex]

[tex]\sqrt{3} - \sqrt{3} = 0[/tex]

So, option D represents a rational number.

[tex](\sqrt{49} )(\sqrt{1} ) \\= 7[/tex]

Answer:

DECIMAL TASK #30

$81.15

Step-by-step explanation:

12.95 x 2 = 25.9

or

12.95 + 12.95 = 25.9

and then

9.75 x 3 = 29.25

or

9.75 + 9.75 + 9.75 = 29.25

and then

the 26 from the popcorn and drinks

25.9 + 29.25 + 26 = 81.15

Answer:

The correct option is;

The domain restriction is correct but the expression for f⁻¹(x) is not

Step-by-step explanation:

The expression for the function is given as follows;

f(x) = x² - 331

The inverse function suggested = f⁻¹(x) = √(x-331)

The domain restriction is x ≥ 0

The inverse function if given as follows;

y = x² - 331 (Interchange x and y to get)

x = y² - 331

x + 331 = y²

y = ±√(x + 331)

Given that the domain restriction has been put as x ≥ 0, we select the + case to give;

f⁻¹(x) = √(x + 331)

Therefore, the domain restriction is correct but the expression for f⁻¹(x) is not.

Answer: B

The domain restriction is correct, but the expression for f–1(x) is not.

Step-by-step explanation:

[tex]4x - 3 < 7[/tex]

Add 3 to both sides of the equation

[tex]4x - 3 + 3 < 7 + 3 \\ 4x < 7 + 3 \\ 4x < 10[/tex]

Divide both sides of the equation by 4

[tex] \frac{4x}{4} < \frac{10}{4} [/tex]

Simplify

[tex]x < \frac{5}{2} [/tex]

The solution to the inequality is x < 5/2.

In Mathematics and Geometry, an inequality is a relation that compares two (2) or more numerical data, number, and variables in an algebraic equation based on any of the inequality symbols;

In this scenario and exercise, we would determine the solution set to the given inequality for x in parts as follows;

4x - 3 < 7

By adding 3 to both sides of the inequality, we have:

4x - 3 + 3 < 7 + 3

4x < 10

x < 10/4

x < 5/2.

Step-by-step explanation:

for 1 jeans

7% tax=7/100×25.68

=1.7976

So 1.7976$ is charged on one jeans.

7% tax for 2 jeans =2×1.7976

=3.5952$

Total price=3.5952+25.68

=29.2752

7% tax for 3 jeans=3×1.7976

=5.3928

Total price=5.3928+25.68

=31.0728

Hope this answer will help you

Answer:

$51.36

$77.04

Step-by-step explanation:

Multiply the cost of the number of pairs of jeans by the sales tax amount, 7%.

cost of 2 pairs:   48 + 7/100 x 48 = $51.36

cost of 3 pairs:   72 + 7/100 x 72 = $77.04

Answer:

the number of ways in which the prizes are allocated is 67,525

Step-by-step explanation:

Given that

Number of customers = 75

Number of prizes = 3

And, the value of gift card = $10

Based on the above information,

The number of ways in which the prizes are allocated is shown below:

[tex]=^{75} C_3[/tex]

= [tex]\frac{75!}{(3!\times(75-3)!}[/tex]

After solving this the number of ways that came is 67,525

hence, the number of ways in which the prizes are allocated is 67,525

Area of circle:

Since d = 28 cm and π = 22/7, the area is:

Answer: 7 cm

Step-by-step explanation: The formula for this type of question is; √2×d÷2 where d stands for the diagonal so, √2×10÷2 = 7.071067812, to the nearest cm is 7cm.

Answer:

7 cm

Step-by-step explanation:

The diagonal divides the square into 2 right triangles.

Using Pythagoras' identity with the diagonal as the hypotenuse.

let x be the side of the square, then

x² + x² = 10²

2x² = 100 ( divide both sides by 2 )

x² = 50 ( take the square root of both sides )

x = [tex]\sqrt{50}[/tex] ≈ 7 cm ( to the nearest cm )
