=01000101

is the answer

The binary value of the given expression is 111101.

To multiply binary numbers, we use the same process as with decimal numbers, but using only 0s and 1s. We can use the distributive property of multiplication to break down the problem into simpler multiplication and addition operations.

First, we multiply 1101 by 101:

                                  1101

                                x  101

                                  -----

                                  1101

                                  1101

                                ------

                              111001

Next, we add 100 to the result:

                              111001

                            +    100

                               -------

                              111101

The decimal value of 111101 is given by,

                              (111101)₂ = (61)₁₀

Therefore, the product of 1101 and 101, plus 100, is 111101 in binary.

In linear equation, the store will get $468.72 from the sale of the couch.

What in mathematics is a linear equation?

An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.

                           Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

a.

Commission can be referred to as the reward given by the company on goods for the employee to sell products in order to make more sales and more money.

Commission is calculated as follows:

Total commission = Total Sales * Commission Percentage

Given

Total Sales = $495

Commission Percentage = 5½%

Substitute in, the above values

Total Commission = $496 * 5½%

Total Commission = $496 * 5.5%

Total Commission = $496 * 0.055

Total Commission = $27.28

Hence, the total commission is calculated as $27.28

b. The amount remitted to the store is calculated as

Amount = Total Sales - Total Commission

Where Total Sales = $496

Total Commission = $27.28

Amount = $496 - $27.28

Amount = $468.72

Hence, the store will get $468.72 from the sale of the couch.

Check the picture below.

let's recall that on an isosceles triangle, twin sides make twin angles.

With a volume of 700 cubic feet and a height of 9 feet , the radius of cylinder is 3.49 feet after rounding to nearest hundredth.

To find the radius of a right cylinder, you need to know its volume and height. The formula for the volume of a cylinder is given by:

V = πr^2h

Where r is the radius, h is the height, and π is approximately equal to 3.14.

Given that the volume is 700 cubic feet and the height is 9 feet, we can substitute these values into the formula:

700 = πr^2 * 9

Dividing both sides by π * 9:

700 / (π * 9) = r^2

Taking the square root of both sides:

√(700 / (π * 9)) = r

Using a calculator and rounding to the nearest hundredth, we find that:

r ≈ 3.49

So the radius of the cylinder is approximately 3.49 feet.

The cost of nails can be represented as 12.99n, and the cost of screws can be represented as 14.99s.

The cost of buying nails and screws can be represented by a system of inequalities where "n" represents the number of boxes of nails and "s" represents the number of boxes of screws.

The cost of one box of nails is $12.99 and the cost of one box of screws is $14.99. Hence, the cost of "n" boxes of nails is represented by 12.99n and the cost of "s" boxes of screws is represented by 14.99s. The carpenter has a budget of $60 and can spend no more than that.

Therefore, the combined cost of buying nails and screws must be less than or equal to $60. This requirement can be represented by the inequality 12.99n + 14.99s <= 60.

To make the calculation easier, we can also express the inequality as n + s <= 4.62, where 4.62 is obtained by dividing $60 by $12.99. This system of inequalities represents the carpenter's budget constraint and helps to determine the number of boxes of nails and screws that can be purchased within the budget.

The expected time (also known as the expected value or the mean) Is approximately 12.5 days.

The expected time for an activity is the average time it is likely to take, taking into account its optimistic, most likely, and pessimistic estimates. The three-point estimate formula is used to calculate the expected time by weighting the most likely estimate four times as much as the optimistic and pessimistic estimates. In this case, the optimistic time is 15 days, the most likely time is 18 days, and the pessimistic time is 27 days. By plugging these values into the formula, the expected time is calculated to be 12.5 days. This means that, on average, the activity is likely to take 12.5 days to complete.

The expected time (also known as the expected value or the mean) can be calculated using the three-point estimate formula, which is:

Expected time = (Optimistic time + 4 * Most likely time + Pessimistic time) / 6

Plugging in the values, we get:

Expected time = (15 + 4 * 18 + 27) / 6 = (75) / 6 = 12.5

So the expected time for this activity is 12.5 days.

The average speed of whole trip was 6.7 mile per hour.

Average speed is calculated by dividing a quantity by the time required to obtain that quantity. Meters per second is the SI unit of speed. The formula S = d/t, where S is the average speed, d is the total distance, and t is the total time, is used to determine average speed.

Given that, the total distance =6+6=12 miles and total time

=58+49= 107 minutes

So, number of hours = 107/60

= 1.8 hours

Now, the average speed = 12/1.8

any point and its coordinates is an ordered pair of (x, y).

in other words, we get the x value used for the function and the resulting y value.

if the equation is true for such a pair, then the point is on the line. if it is false, then not.

y = (-5/4)x + 5

(4, 0)

0 = (-5/4)×4 + 5 = -5 + 5 = 0

true.

(0, 5)

5 = (-5/4)×0 + 5 = 0 + 5 = 5

true.

y + 5 = (-5/4)(x - 4)

(4, 0)

0 + 5 = (-5/4)(4 - 4)

5 = (-5/4)×0 = 0

false.

so, II is not containing (4, 0).

According to the given data, Ryan walked 12 small dogs.

Let x be the number of small dogs that Ryan walked.

The number of large dogs that Ryan walked would then be y = 4 - x.

Using the information given, we can set up the following equation:

x * 2 + (4 - x) * 5 = 40

Expanding and solving for x, we get:

2x + 4 - 5x = 40

-3x = 36

x = 12

So, Ryan walked 12 small dogs.

In this problem, we used a system of equations to solve for the unknown variable, x, which represents the number of small dogs that Ryan walked. By substituting this value back into the equation for the number of large dogs, we were able to confirm that Ryan walked 4 - x = 4 - 12 = 4 large dogs.
