Step-by-step explanation:

It takes Ermias and Manuel 3.43 hours to paint the room if they are working together. To find the time it takes for Ermias and Manuel to paint the room together, we can use the formula: 1/rate = time.

The rate is the combined painting rate of both workers, which is equal to the sum of their individual painting rates.

Let's call the time it takes for Ermias and Manuel to paint the room together "T". The combined painting rate of both workers is then 1/T.

The individual painting rates of Ermias and Manuel are 1/8 hours per room and 1/6 hours per room, respectively. Therefore, their combined painting rate is 1/8 + 1/6 = 6/48 + 8/48 = 14/48 hours per room.

Now we can use the formula 1/rate = time to find T:

1/ (14/48) = T

48/14 = T

T = 3.43 hours

So it takes Ermias and Manuel 3.43 hours to paint the room if they are working together.

The probability of selecting 6 both times is 0.0125 or 1.25%

In this problem, we need to find the probability of selecting 6 two times when we randomly select an integer from 0 to 7 and then randomly select an integer from 0 to 9.

We can solve this problem by multiplying the probability of selecting 6 from 0 to 7 by the probability of selecting 6 from 0 to 9.

Given,We randomly select an integer from 0 to 7 (inclusively) and then randomly select an integer from 0 to 9 (inclusively).

We need to find the probability of selecting 6 both times.

The probability of selecting 6 from 0 to 7 = Number of ways of selecting 6 from 0 to 7 / Total number of integers from 0 to 7

= 1/8

= 0.125

The probability of selecting 6 from 0 to 9

= Number of ways of selecting 6 from 0 to 9 / Total number of integers from 0 to 9

= 1/10

= 0.1

We need to find the probability of selecting 6 both times,

P (6,6) = P (6) × P (6)

= 0.125 × 0.1 = 0.0125.

Hence, the probability of selecting 6 both times is 0.0125 or 1.25% (rounded to two decimal places).

The solution to the quadratic equation -3 = 4x² + 9x using quadratic formula is; x = (-9 + √33)/8 or (-9 - √33)/8

The general form of any quadratic equation is written as;

ax² + bx + c = 0

The quadratic formula that is used to solve this is given by;

x = [-b ± √(b² - 4ac)]/(2a)

Now, we are given the quadratic equation as;

-3 = 4x² + 9x

It can be written as;

4x² + 9x + 3 = 0

Thus, using quadratic formula we have;

x = [-9 ± √(9² - (4 * 4 * 3))]/(2 * 4)

x =  [-9 ± √(81 - 48)]/8

x = (-9 ± √33)/8

x = (-9 + √33)/8 or (-9 - √33)/8

By using the fact that the two angles are vertical angles, we will write and solve a linear equation to fine that the value of x is 20.

Here we assume that both of the horizontal lines are parallel. Then the two marked angles (the ones that depend of x) are vertical angles.

This means that the measure of these angles is the same one, then we can write:

(5x - 8)° = (3x + 32)°

So we can solve that linear equation to find the value of x, we will get:

5x - 8 = 3x  + 32

Grouping like terms we get:

5x - 3x = 32+ 8

2x = 40

x = 40/2

x = 20

The value of x is 20.

Answer: (60/13, 6/13)

Concept:

There are three general ways to solve systems of equations:

Here, we are going to use elimination since all the variables are in the corresponding position.

Solve:

Given

\(\left \{ {{2x+7y=-6} \atop {4x - y=18}} \right.\)

Multiply the first equation in order to eliminate [x]

\(\left \{ {{4x + 14y = -12} \atop {4x - y = 18}} \right.\)

Subtract the second equation from the first equation to eliminate [x]

\(14y-y=-12+18\)

\(13y=6\)

Divide 13 on both sides

\(13y/13=6/13\)

\(\boxed{y=\frac{6}{13} }\)

Substitute [y] value in order to get [x] value

4x - y = 18

4x - 6/13 = 18

4x = 18 + 6/13

4x = 240/13

\(\boxed{x=\frac{60}{13} }\)

Answer:

The measure of arc SQ is 95° ⇒ (1)

Step-by-step explanation:

In the given circle

∵ S lies on the circumference of the circle

∴ ∠QSR is an inscribed angle

∵ ∠QSR is subtended by arc QR

→ By using the 2nd rule above

∴ m arc QR = 2 × m∠QSR

∵ m∠QSR = 95°

∴ m arc QR = 2 × 95

∴ m arc QR = 190°

→ By using the 1st rule above

∵ m of the circle = m arc QR + m arc SQ + m arc SR

∵ m arc SR = 75° and m arc QR = 190°

→ Substitute them in the equation above

∴ 360 = 190 + m arc SQ + 75

→ Add the like term in the right side

∴ 360 = 265 + m arc QS

→ Subtract 265 from both sides

∵ 360 - 265 = 265 - 265 + m arc SQ

∴ 95° = m arc SQ

∴ The measure of arc SQ is 95°

Note that the distance to the tower and the height of the tower create a right triangle at the base of the tower.  The equation to find the height of a right triangle is to multiply the length times the tangent of angle β.

Given:

b = a · tanβ

tan(30°) = √3/3

Step 1:  Solve

b = (30/1) · (√3/3)

b = (30 · √3) / (1 · 3)

b = (30√3) / (3)

b = 10√3

1. The equation for the sum of torques in Part B1 is Στ = τA + τF = mAMAg + mFGF.

2. The equation for the sum of torques in Part B2 is Στ = τA + τF = mAMAg - mFGF.

3. Solving the equations, we find that mA = Στ / (2Ag) and mF = 0.

4. One way to check the calculated masses is by using the PHET program with known values for torque and gravitational acceleration, comparing the results with the actual masses used in the experiment.

Let us discussed in a detailed way:

1. The equation for the sum of torques in Part B1 can be written as:

Στ = τA + τF = mAMAg + mFGF

2. The equation for the sum of torques in Part B2 can be written as:

Στ = τA + τF = mAMAg - mFGF

3. Solving the equations for the unknown masses, mA and mF, can be done by setting up a system of equations and solving them simultaneously. From the equations in Part B1 and Part B2, we have:

For Part B1:

mAMAg + mFGF = Στ

For Part B2:

mAMAg - mFGF = Στ

To solve for the unknown masses, we can add the equations together to eliminate the term with mF:

2mAMAg = 2Στ

Dividing both sides of the equation by 2mAg, we get:

mA = Στ / (2Ag)

Similarly, subtracting the equations eliminates the term with mA:

2mFGF = 0

Since 2mFGF equals zero, we can conclude that mF is equal to zero.

Therefore, the solution for the unknown masses is mA = Στ / (2Ag) and mF = 0.

4. One way to use the PHET program to check the masses calculated in question 3 is by performing an experimental setup with known values for the torque and gravitational acceleration. By inputting these known values and comparing the calculated masses mA and mF with the actual masses used in the experiment, we can determine if the results agree.

Step-by-step explanation:

To find the differential of the function y = s / (5 + 9s), we differentiate it with respect to s. The resulting differential gives us an expression for the rate of change of y with respect to s.

To differentiate the function y = s / (5 + 9s) with respect to s, we use the quotient rule of differentiation. The quotient rule states that for a function u/v, the derivative is given by (v * du/ds - u * dv/ds) / v^2.

In this case, u = s and v = (5 + 9s). Using the quotient rule, we have:

dy/ds = [(5 + 9s) * d/ds(s) - s * d/ds(5 + 9s)] / (5 + 9s)^2

Since d/ds(s) = 1 and d/ds(5 + 9s) = 9, we can simplify the expression:

dy/ds = (5 + 9s - 9s) / (5 + 9s)^2

Simplifying further, we have:

dy/ds = 5 / (5 + 9s)^2

Therefore, the differential of the function y = s / (5 + 9s) is dy/ds = 5 / (5 + 9s)^2. This represents the rate of change of y with respect to s.

To find the differential of the function y = s / (5 + 9s), we differentiate the function with respect to s. The resulting differential represents the change in y for a small change in s.

We start by rewriting the given function as y = s / (5 + 9s) = s(5 + 9s)^(-1). To find the differential, we differentiate this function with respect to s using the quotient rule.

Applying the quotient rule, the derivative of y with respect to s is given by:

dy/ds = (5 + 9s)^(-1) - s(9)(5 + 9s)^(-2)(9) = (5 + 9s)^(-1) - 81s(5 + 9s)^(-2)

Therefore, the differential of the function y = s / (5 + 9s) is dy/ds = (5 + 9s)^(-1) - 81s(5 + 9s)^(-2). This expression represents the rate of change of y with respect to s.
