George can build a laptop twice as fast as her working together it takes them three hours which equation would you use to determine how long it would take Kurt working alone
Answers
Since George can build a laptop twice as fast as Kurt and working together takes them 3 hours, an equation which you would use to determine how long it will take Kurt working alone is: D. 1/t + 1/2t = 1/3.
How to determine the amount of time it would take Kurt working alone?In order to determine the amount of time it would take Kurt working alone, we would have to assign variables to the amount of time taken by George to build a laptop and the amount of time taken by Kurt to build a laptop, and then translate the word problem into an algebraic equation (expression) as follows;
Let the variable g represents the amount of time taken by George to build a laptop.Let the variable t represents the amount of time taken by Kurt to build a laptop.Let the variable w represents the combined work rate.Since George can build a laptop twice as fast as Kurt, an equation which models this situation is given by;
g = 2t .....equation 1.
Next, we would write an algebraic equation (expression) that models the combined work rate;
1/c = 1/t + 1/g .....equation 2.
Substituting equation 1 into equation 2, we have the following:
1/3 = 1/t + 1/2t
1/t + 1/2t = 1/3.

Chau used 6 rolls of blue fabric to make costumes for the annual school play. He used the total length of 14.4yd of fabric. If each roll had the same length of fabric, how much fabric was in each roll? Write your answer in inches.
Answers
Answer: Each roll of fabric had 86.4 inches of fabric.
Step-by-step explanation:
Each roll of fabric used in the annual school play had a length of 14.4yd / 6 rolls = 2.4 yards of fabric.
1 yard = 36 inches
so, 2.4 yards = 2.4 x 36 inches = 86.4 inches
Each roll of fabric had 86.4 inches of fabric.
Explanation: The problem states that Chau used 6 rolls of blue fabric, and the total length of fabric used was 14.4 yards. Dividing the total length of fabric by the number of rolls gives the length of each roll, which is 2.4 yards or 86.4 inches.

Answers
Using substitution method to solve the system of linear equations, the value of x and y are 4 and -24 respectively.
What is system of linear equationA system of linear equations is a set of two or more linear equations that contain two or more variables. The goal of solving a system of linear equations is to find the values of the variables that satisfy all of the equations in the system simultaneously. Linear equations are equations that can be written in the form of ax + by = c, where a, b, c, x and y are constants.
In this problem, the equations are
y = -6x ...eq(i)-2x - y = 16 ...eq(ii)Using substitution method;
Put the value y in eq(i) into eq(ii)
-2x - (-6x) = 16
-2x + 6x = 16
4x = 16
x = 4
Put x = 4 into equ(i)
y = -6(4)
y = -24
The value of x and y are 4 and -24

A 1.5 kg pendulum swings from point A of height yA = 0.04m to point B of height yB = 0.12m. The heights are relative to the lowest height. What is the change in gravitational potential energy from A to B?
Answers
Answer:
The change in gravitational potential energy from point A to point B can be calculated using the formula:
ΔU = mgh
Where:
m = mass of the pendulum = 1.5 kg
g = acceleration due to gravity = 9.8 m/s^2
h = change in height = yB - yA = 0.12 m - 0.04 m = 0.08 m
So, the change in gravitational potential energy from A to B is:
ΔU = (1.5 kg)(9.8 m/s^2)(0.08 m) = 1.176 J
So, the change in gravitational potential energy from A to B is 1.176 Joules.

Which expression is equivalent to 3 square root 27c7 • 3 square root 250c2, if c≠0
Answers
Answer:3 square root 27c7 • 3 square root 250c2 can be simplified by applying the property of square roots, (√a * √b) = √(ab) .
So, 3 square root 27c7 • 3 square root 250c2 = √(27c7 * 250c2) = √(27250c7c2) = √(675c7*c2) = √(675c9) = √(675) * √(c9) = 15c3
Therefore, 3 square root 27c7 • 3 square root 250c2 = 15c3 is the equivalent expression.

Which is equal to sin31°?
Answers
Answer: 0.515
Step-by-step explanation:
Since our angle is between 0 and 90 degrees, it is located in Quadrant I
In the first quadrant, the values for sin, cos and tan are positive.
Since 31° is less than 90, we can express this in terms of a cofunction
sin(θ) = cos(90 - θ)
sin(31) = cos(90 - 31)
sin(31) = cos(59)
hope this helps!
The value of sin 31° is 0.51504.
Sin 31 degrees is the value of the sine trigonometric function for an angle equal to 31 degrees.
The sin of 31 degrees is 0.51504, but the sin of 31 degrees can also be expressed in radians. To obtain 31 degrees in radian multiply 31° by π/ 180° = 31/180π. Sin 31degrees = sin (31/180 ×π)
The results of sin31° are rounded to five decimal places.
The following are identities of sine 31° :
sin31°
= cos (90°-31°) = cos 59°
= sin (180°-31°) = sin 149°
-sin31°
= cos (90°+31°) = cos 121°
= sin (180°+31°) = sin 211°
Therefore, The value of sin 31° is 0.51504.

The domain and range are (0 , ∞) and (0 , ∞).
What is domain ?
The collection of all potential inputs for a function is its domain. For instance, the domain of f(x)=x2 and g(x)=1/x are all real integers with the exception of x=0.
The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
The set of all initial elements in ordered pairs constitutes the domain (x-coordinates). The set of all second items in ordered pairs is the range (y-coordinates).
Given
y = 80 / x
As per the graph the domain and range are
domain : (0 , ∞)
{depth of the diamond > 0 }
