Answer:

y = -2/3x -5

Step-by-step explanation:

First, let's fill in our equation of y = mx + b

(6, -9) is the coordinate we will be subsituting

If the equation that s to the one we are solving we must turn its slope into it's negative reciprocal, which would go from 3/2 to -2/3

Now let's substitute and solve

y = mx + b

(-9) = -2/3(6) + b

-9 = -4 +b

+4   +4

-5 = b

Now we create the equation

y = -2/3x -5

Using conditional probability, it is found that there is a 0.275 = 27.5% probability of choosing Urn 1 and a white marble.

Step-by-step explanation:

Raphael could finish the job in 3/2 hr = 90 min. Matilde could finish the job in 3 hr.

Let M denote for matilde

R for Raphael.

I assume they worked on the task together to finish it in 1 hr.

M does 1/M of the job per hr.

R does 1/R of the job per hr.

(1/M + 1/R) * x hr = 1 whole job completed

We are told x = 1 hr, so that's done.

We are told M's rate of work is 1/2 of R's

R's rate of work is 1/R

1/2 * 1/R = 1/2R

substitute 1/2R for 1/M

(1/2R + 1/R) * 1 hr = 1 whole job completed

solve

(R+ 2R)/ 2R^2 = 1

3R /2R^2 = 1

3R = 2R^2

2R^2 -3R = 0

R(2R-3) = 0

R = 0 or 2R = 3

However, if R could do the work in 0 hours, then his rate of work would be undefined.

Therefore, we select 2R = 3, which means R= 3/2.

R can do the whole job in 3/2 hr working alone.

M can do the whole job in 2*3/2 = 3 hr working alone.

We can check this solution to be sure it is correct.

In 1 hr, R can do 2/3 of the job.

In 1 hr, M can do 1/3 of the job

2/3+1/3 = 1.

We also can substitute in the original equation as double-check.

(1/3 + 1/(3/2))*1 = 1 ??

(1/3 + 2/3) = 1

Answer: R could finish the job in 3/2 hr = 90 min. M could finish the job in 3 hr.

The concrete cost for the pillar was $37,879.52.

Velocity is a quantity that indicates how quickly and in which direction a point is moving. A point always moves in a direction that is tangent to its path; for example, a circular path's direction at any instant is perpendicular to a line connecting the point to the circle's centre (a radius). The magnitude of the velocity (or speed) is the rate at which the point moves along its path in time.

If a point moves a certain distance along its path in a given time interval, its average speed is equal to the distance moved divided by the time taken. A train travelling 100 kilometres in two hours, for example, has an average speed of 50 kilometres per hour.

The cylinder's radius is equal to its diameter divided in half, or 12/2, or 6 metres.

The cylinder's volume is determined by:

\(V = pi * r^2 * h\)

\(V = 3.14 * 6^2 * 4\)

V equals 452,16 cubic metres

The price of the concrete is $82 per cubic metre, making the overall price:

$82 * 452.16 = $37,879.52

Hence, the pillar's concrete expense came to $37,879.52.

a. The student must pay $306.25 in interest.

To calculate the amount of interest, we can use the formula for simple interest:

Interest = Principal × Rate × Time

In this case, the principal (loan amount) is $5000, the rate is 8.25%, and the time is 9 months (expressed in years as 9/12).

Plugging in these values into the formula, we can calculate the interest amount the student must pay.

b. The future value of the loan is $5306.25.

To find the future value, we add the interest amount to the principal amount.

The future value is calculated using the formula:

Future Value = Principal + Interest

By substituting the values of the principal ($5000) and the interest ($306.25), we can find the future value of the loan.

Therefore, the student will have to pay $306.25 in interest, and the future value of the loan will be $5306.25.

By applying the Law of Cosines, we can determine the length of the third side, BC, given that side AB is 37 cm, side AC is 26 cm, and angle B is 32.5°. In order to perform this, we must first determine the cosine of angle B, which comes out to be 32.5°. Then, we enter this value, together with the lengths of AB and AC, into the Law of Cosines equation to obtain BC.BC = (AB2 + AC2 - 2(AB)(AC)cosB) is the equation. BC is then calculated by plugging in the known variables to obtain (37 + 26 - 2(37)(26)cos32.5°). By condensing this formula, we arrive at BC = (1369 + 676 - 1848cos32.5°). Then, we calculate BC as BC = (2095 - 1539.07), and finally, we simplify to obtain BC = 556.93. Finally, we determine that BC is 23.701 cm.

The decimal value of the sum of the two 5-bit two's complement numbers 10010 and 10101 is -5.

In two's complement representation, the leftmost bit represents the sign, with 0 indicating a positive number and 1 indicating a negative number. To perform the addition, we start by adding the least significant bits (LSBs) together, which gives us 0+1 = 1. Since both numbers are positive, the sum is also positive. Moving on to the next bit, we have 1+0 = 1. Continuing this process, we add 0+1 = 1, 0+0 = 0, and 1+0 = 1 for the remaining bits. However, when performing two's complement addition, we ignore any carry that occurs beyond the most significant bit (MSB).

The MSB in the sum is 1, indicating a negative number. To find the decimal value, we convert the remaining bits (01101) from two's complement to decimal. In two's complement, the leftmost bit is weighted as -16, the next bit as 8, then 4, 2, and 1 for the subsequent bits. Multiplying the bits by their respective weights and summing them up, we have -8 + 4 + 1 = -3. Therefore, the decimal value of the sum of 10010 and 10101 is -5.

Answer:

8x = 32

x = 4

y = 6

Step-by-step explanation:

2.5y + 3x = 27

5x – 2.5y = 5

_____________

8x = 32 (equation obtained after adding the two equations)

x = 32/8

x = 4

Plug x = 4 in 2.5y + 3x = 27

2.5y + 3*4 = 27

2.5y + 12 = 27

2.5y = 27 - 12

2.y5= 15

y = 15/2.5

y = 6

The equation results of adding the two equations is 8x = 32.

The solution to the system is (4, 6).

A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.

Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.

An example of a non-linear function is a quadratic function.

Given, A system of linear equations in variables 'x' and 'y'.

2.5y + 3x = 27...(i) and 5x - 2.5y = 5...(ii)'

Reaaranging eqn(i) we have

3x + 2.5y = 27...(iii)

Adding (ii) and (ii) we have,

8x = 32.       (As + 2.5y and - 2.5y cancels)

x = 32/8.

x = 4.

Putting the value of 'x' in eqn(i) we have,

2.5y + 12 = 27.

2.5y = 15.

y = 6.

So, The solution to the system is (4, 6).
