Answer:

x^(1/12).

Step-by-step explanation:

By the laws of indices:

(x ^ 1/2)^1/6)

= x ^(1/2*1/6)

= x^(1/12).

The area of the room = (40 x 24) - (20 x 12)

Area = 960 - 240 = 720 square feet

Divide square feet by width of a strip:

720 / 12 = 60 linear feet.

The answer is D.

Answer : The correct option is, (D) 60

Step-by-step explanation :

First we have to calculate the area of room.

Area of room = Area of big rectangle + Area of small rectangle

Area of rectangle = Length × Width

Area of room = (40 × 12) + (20 × 12)

Area of room = 720 square feet

Now we have to calculate the number of linear feet will he need to buy.

Number of linear feet = [tex]\frac{\text{Area of room}}{\text{Width of carpet strips}}[/tex]

Number of linear feet = [tex]\frac{720}{12}=60[/tex]

Thus, the number of linear feet will he need to buy is, 60

12. Answer below:

"one half" = [tex]\frac{1}{2}[/tex]

"negative five eighths" = [tex]\frac{-5}{8}[/tex]

To evaluate the expression, you multiply the two numbers together:

[tex]\frac{1}{2} * \frac{-5}{8} = \frac{1 * -5}{2 * 8} = \frac{-5}{16}[/tex]

13. Answer below:

"one third" = [tex]\frac{1}{3}[/tex]

"eleven sixteenths" = [tex]\frac{11}{16}[/tex]

To evaluate the expression, you multiply the two numbers together

[tex]\frac{1}{3} * \frac{11}{16} = \frac{1 * 11}{3 * 16} = \frac{11}{48}[/tex]

Check the picture below.

The measure of m∠EBC if m∠EBD = 36° and m∠DBC = 108° is 144degrees

The point where two lines intersect is known as the angle.

From the diagram shown:

m∠EBC = m∠EBD + m∠DBC

Given the following:

m∠EBD = 36degrees

m∠DBC = 108degrees

Substitute the given values into the expression as shown:

m∠EBC = 36 + 108

m∠EBC = 144degrees

Hence the measure of m∠EBC is 144degrees

The classification of the numbers into rational and irrational are:

1. Pi is irrational

2. 7 squared is irrational

3. 7.1234... is irrational

1) π is a mathematical expression whose approximate value is 3.14159365…

The given value of π is expressed in decimal which is non-terminating and non-repeating. As the value is non-terminating it shows the nature of irrational numbers. Hence, π is not a rational number

2) 7 squared is not a perfect square and as such it will have non-terminating and non-repeating decimal and so it is irrational.

3) 7.1234... is an irrational number because it is non-terminating and non-repeating decimal.

Answer:

B. No solutions.

Step-by-step explanation:

Let's try solving it:

3(x + 8) = 3x + 4

3x + 8 = 3x + 4.

There are no solutions  because if we simplify we get an absurd result. Subtract 3x from both sides of the equation:

3x - 3x + 8 = 3x - 3x + 4

8 = 4.

There are no solutions for x in this equation.

To solve this equation, we need to combine like terms and isolate the variable. Here are the steps:

Since 23 does not equal 4, these two sides are not equal. Therefore, there are no solutions for x in this equation.

Answer:

X²+4x+3=0

Step-by-step explanation:

y = X² + 4x + 3

y = 0

Solution:

x = -3, x² = -1

Steps:

X² + 4x + 3 = 0

write 4x as a sum

X²+ 3x + x + 3 = 0

Factor out x from expression

X (x + 3) + x + 3 = 0

Factor out x + 3 from expression

(x + 3) x (x + 1) = 0

When the product of factors equals 0, at least one factor is 0

x + 3 = 0

x + 1 = 0

solve for x

x = -3

x + 1 = 0

solve for x

x = -3

x = -1

The final solutions are

X = -3, X² = -1

Answer:

Option A.

Step-by-step explanation:

The vertex form of a parabola is

[tex]y=a(x-h)^2+k[/tex]

where, (h,k) is vertex and a is a constant.

The vertex of the parabola is (-2,-1).

Substitute h=-2 and k=-1 in the above equation.

[tex]y=a(x-(-2))^2+(-1)[/tex]

[tex]y=a(x+2)^2-1[/tex]     .... (1)

The parabola passes through the point (0,3). So, it must be satisfy by the point (0,3).

[tex]3=a(0+2)^2-1[/tex]

[tex]3+1=4a[/tex]

[tex]a=1[/tex]

Substiturte a=1 in equation (1).

[tex]y=1(x+2)^2-1[/tex]

On simplification we get

[tex]y=x^2+4x+4-1[/tex]

[tex]y=x^2+4x+3[/tex]

It means the equation [tex]x^2+4x+3=0[/tex] could be solved using the given graph.

Answer:

Area of the rug will be 6912 square inches.

Step-by-step explanation:

Rob has purchased a rug having measurement 72 inches by 98 inches for his apartment.

Since the rug will be in the shape of a rectangle, area will be represented by the formula,

Area = Length × width

        = 72 × 96

        = 6912 square inches.

Therefore, area of the rug will be 6912 square inches.

To calculate the area of Rob's rug, multiply the length of 96 inches by the width of 72 inches, resulting in an area of 6,912 square inches. Thus, the area of the rug is 6,912 square inches.

To find the area of Rob's rug, you need to multiply the length and the width of the rug.

The formula for area is:

Area = Length × Width

Using the given dimensions:

Area = 96 inches × 72 inches = 6,912 square inches

Therefore, the area of the rug is 6,912 square inches.

Paulo's time in standard notation is 15,600 seconds. Miguel ran the marathon in a shorter time of 15,360 seconds. For the given equations, A) and B) each have one solution (x=3 and x=10, respectively), while C) has an infinite number of solutions.

To convert Paulo's time from scientific to standard notation, we multiply 1.56 by 10 to the power of 4. This equals 15,600 seconds. Next, we need to convert Miguel's time to seconds to directly compare the two durations. Miguel ran for 4 hours and 16 minutes, which is equal to (4 × 3600) + (16 × 60) = 14,400 + 960 = 15,360 seconds. Therefore, Miguel ran the race in a shorter amount of time by 240 seconds.

For question 2, we solve the following equations:

For equation A) 2x + 4(x - 1) = 2 + 4x, after simplifying we get 2x + 4x - 4 = 2 + 4x. The 4x terms cancel out and we are left with 2x - 4 = 2. Solving for x gives x = 3. This equation has one solution.

For equation B) 25 - x = 15 - (3x + 10), simplifying gives 25 - x = 5 - 3x. Solving for x yields x = 10, so this equation also has one solution.

For equation C) 4x = 2x + 2x + 5(x - x), simplifying results in 4x = 4x, which is true for all values of x. Therefore, this equation has an infinite number of solutions.

As question 3 involves an image that we cannot see here, this part of the student's question has been left unanswered.

Final answer:

To create a 35% saline solution by mixing a 50% and a 30% solution, the nurse needs to use 6000cc of the 30% solution.

Explanation:

The question asks how much of a 30% saline solution a nurse needs to mix with 60cc of a 50% saline solution to achieve a final solution concentration of 35%. To solve this problem, let's denote the volume of the 30% solution needed as x cc. Using the concept of weighted averages for concentrations, we can set up the following equation:

(60cc × 50%) + (x cc × 30%) = (60cc + x cc) × 35%

Solving this equation, we get:

3000 + 0.3x = 0.35(60 + x)

3000 + 0.3x = 21 + 0.35x

Subtracting 0.3x from both sides:

3000 = 21 + 0.05x

Subtracting 21 from both sides and dividing by 0.05:

x = 6000 cc

Therefore, the nurse should use 6000cc of the 30% saline solution to achieve the desired concentration.

The answer is 2/3 okay? Pls thx me!

The third number to the left of the decimal is the hundreds, so you have 200.

The 2nd number to the left of  the decimal is the tens, so you have 30.

The first number to the left of the decimal is the ones, and you have 0 ones, so you have 0.

The first number to the right of the decimal is the tenths place, which is 0 so it is 0.0

The second number to the right is the hundredths place, which is 0.07

The third number is the thousandths place, which is 0.001

The expanded form becomes:

200 + 30 + 0 + 0.0 + 0.07 + 0.001
