The weight of each of the boxes are:

Large box = 15.75 kg

Small box = 18.75 kg

Let the weight of each large box be x

Let the weight of each small box be y.

Thus, if  5 large boxes and 3 small boxes have a total weight of 135 kilograms, then we have the equation:

5x + 3y = 135   -------(1)

Thus, if  7 large boxes and 9 small boxes have a total weight of 279 kilograms, then we have the equation:

7x + 9y = 279     ------(2)

Multiply eq 1 by 3 and eq 2 by 1 to get:

15x + 9y = 405   -----(3)

Subtract eq 2 from eq 3 to get:

8x = 126

x = 126/8

x = 15.75 kg

Thus:

5(15.75) + 3y = 135

3y = 135 - 78.75

3y = 56.25

y = 18.75 kg

If ABCD is dilated by a scale factor of 3, the coordinate of B' would be (-6, 6).

In Geometry, dilation simply refers to a type of transformation which typically changes the size of a geometric object, but not its shape.

This ultimately implies that, the size of the geometric shape would be increased (stretched or enlarged) or decreased (compressed or reduced) based on the scale factor applied.

Next, we would apply a dilation to the coordinates of the pre-image by using a scale factor of 3 centered at the origin as follows:

Tim has used 11 squares tiles to cover a surface. What is the height of this surface if its base is 12 cm?

Answer: Let's first find out the original price of the watch, before any discount was applied.

Since Libby paid $600, which is 80% of the original price, we can set up the equation:

0.8P = 600

where P is the original price of the watch.

Solving for P, we get:

P = 600/0.8 = $750

So the original price of the watch was $750.

Now, we can find the discount that was given to Scott. He paid $630, which is a discount from the original price of:

$750 - $630 = $120

So the discount amount was $120.

To find the percentage discount, we can use the formula:

Discount percentage = (discount amount / original price) x 100%

Plugging in the values, we get:

Discount percentage = (120 / 750) x 100% = 16%

Therefore, Scott received a 16% discount on the watch.

What is mean absolute deviation?

Mean absolute deviation (MAD) is a measure that describes the average distance between each data point in a set and the mean of that set. It is a way of measuring how spread out the data points are from the average or central value.

The correct answer is d. The mean absolute deviation tells you about the variation of the data points in a set. Specifically, it measures how much the data points deviate, on average, from the mean value of the set.

A higher mean absolute deviation indicates that the data points are more spread out from the mean, while a lower mean absolute deviation indicates that the data points are closer to the mean. The mean absolute deviation is useful for comparing the amount of variation between two or more sets of data, and can provide insight into the consistency or stability of the data.

(a) To find the N-intercept, we set t to 0 in the equation N = -0.3t + 250:

N = -0.3(0) + 250

N = 250

Therefore, the N-intercept is (0, 250).

(b) The N-intercept is the point on the graph where the tuition is $0 and represents the number of students who would enroll in the basketball camp if it were free. In this case, if the tuition was $0, 250 students would enroll in the basketball camp.

(c) To find the t-intercept, we set N to 0 in the equation N = -0.3t + 250 and solve for t:

0 = -0.3t + 250

0.3t = 250

t = 250/0.3

t ≈ 833.33

Therefore, the t-intercept is approximately (833.33, 0).

(d) The t-intercept is the point on the graph where the number of students who enroll in the basketball camp is zero and represents the tuition that would need to be charged for no students to enroll. In this case, if the tuition was approximately $833.33, no students would enroll in the basketball camp.

You will be able to pull out approximately $1,983.45 each month from your retirement savings if you want to be able to take withdrawals for 15 years.

Interest rate is the percentage of the principal amount (a loan or an investment) that is charged or paid over a certain period of time, usually a year. It is used to calculate the amount of interest that accrues on the principal amount.

To calculate the monthly withdrawal amount that you can make from your retirement savings, we can use the present value of an annuity formula. This formula relates the present value of a series of equal periodic payments to the interest rate, the number of periods, and the payment amount.

Let's assume that you want to make monthly withdrawals for 15 years, which corresponds to 180 months. Also, let's assume that you want to withdraw the same amount each month. We can call this amount "P".

Using the present value of an annuity formula, we can solve for P:

P = PV * (r / (1 - [tex](1 + r)^(-n)[/tex]))

where PV is the present value of your retirement savings,

           r is the monthly interest rate (which is 4% / 12 = 0.00333), and

           n is the number of months over which you want to make withdrawals (which is 180 in this case).

Substituting the given values, we get:

P = 300,000 * (0.00333 / (1 - (1 + [tex]0.00333)^(-180)[/tex]))

  ≈ $1,983.45

Therefore, you will be able to pull out approximately $1,983.45 each month from your retirement savings if you want to be able to take withdrawals for 15 years. Note that this amount is an estimate and does not take into account any taxes, fees, or other factors that may affect your retirement income.

the answer of the subsets of the questions are Angle BTC is 198 degree

Arc bd is 90 degree,

How to find the Arc of the circle?

Since points T, C, B, D are on the boundary of a circle and meet at point P, we can conclude that P is the center of the circle.

Let's label the angles at the center of the circle. Since the angle between TCP is 128 degrees, we know that the angle TPC at the center of the circle is twice that, or 256 degrees. Similarly, since the angle between TPB is 90 degrees, we know that the angle TPB at the center of the circle is 180 degrees.

Let's also label the points where the arcs intersect the circle. The arc BD intersects the circle at points B, D, and P. The arc BC intersects the circle at points B, C, and P. The arc BTC intersects the circle at points B, T, C, and P. The arc TDC intersects the circle at points T, D, C, and P.

To find the arc BD, we need to find the central angle that corresponds to that arc. We can do this by adding the angles at the center of the circle that correspond to the arcs that intersect BD. In this case, those angles are TPB and TPC. So the central angle corresponding to arc BD is:

central angle for arc BD = angle TPB + angle TPC

central angle for arc BD = 180 degrees + 256 degrees

central angle for arc BD = 436 degrees

Therefore, the arc BD is a 436-degree arc.

To find the arc BC, we can follow the same process. The angles at the center of the circle that correspond to the arcs that intersect BC are TPB and TPC. So the central angle corresponding to arc BC is:

central angle for arc BC = angle TPB + angle TPC

central angle for arc BC = 180 degrees + 256 degrees

central angle for arc BC = 436 degrees

Therefore, the arc BC is also a 436-degree arc.

To find the arc BTC, we can again follow the same process. The angles at the center of the circle that correspond to the arcs that intersect BTC are TPB and TPC and the angle at the center of the circle that corresponds to arc BC. So the central angle corresponding to arc BTC is:

central angle for arc BTC = angle TPB + angle TPC + angle BPC

central angle for arc BTC = 180 degrees + 256 degrees + (360 degrees - angle BC)/2

central angle for arc BTC = 436 degrees + (360 degrees - angle BC)/2

To find angle BC, we can use the fact that the angles in a triangle sum to 180 degrees. So:

angle B + angle C + angle TCP = 180 degrees

Since TCP is 256 degrees, we can solve for angle BC:

angle B + angle C = 180 degrees - 256 degrees

angle B + angle C = -76 degrees

Since angles in a circle cannot be negative, we made an error somewhere. In fact, it is not possible for the given angles to correspond to a circle with center P. If we assume that the given angles are correct, we can conclude that there is no circle that contains all four points T, C, B, and D.

What is circumference ?

Let's start by finding the diameter of Circle A. The formula for the circumference of a circle is:

C = πd

where C is the circumference and d is the diameter.

So we can solve for the diameter of Circle A by rearranging the formula:

d = C/π = 23/π

Now we can find the diameter of Circle B, which is 1½ times as long as Circle A's diameter:

d(B) = 1.5d(A) = 1.5(23/π)

Next, we can use the formula for the circumference of a circle to find the circumference of Circle B:

C(B) = πd(B)

C(B) = π(1.5)(23/π)

C(B) = 1.5(23)

C(B) = 34.5 meters

Therefore, the circumference of Circle B is 34.5 meters.

Globes are often used as educational tools to help people visualize and understand the geography, topography, and other features of the Earth or other planets. They can be used in classrooms, museums, or other settings to teach geography, astronomy, or other related subjects.

Globes can also be decorative objects, used to add visual interest to a room or office. They come in a variety of sizes, styles, and designs, ranging from small desktop globes to large, ornate globes mounted on stands.

The formula for the volume of a sphere is V = (4/3)πr³, where V is the volume, π is the mathematical constant pi (approximately 3.14), and r is the radius of the sphere.

Using this formula and substituting the given radius of 9 inches, we can calculate the volume of the globe as follows:

V = (4/3)πr³

V = (4/3)π(9³)

V = (4/3)π(729)

V = 3053.63 cubic inches (rounded to two decimal places)

Therefore, the volume of the spherical globe with a radius of 9 inches is approximately 3053.63 cubic inches.

It's important to note that the volume of a sphere is a measure of the amount of space inside the sphere, so the volume represents the maximum amount of material that can fit inside the sphere.

The gymnast would pay a total of $50 per month for his membership to the yoga studio if he attends 3 classes per month.

What is the linear equation?

A linear equation is an algebraic equation of the form y=mx+b. where m is the slope and b is the y-intercept.

The equation y = 20 + 10x represents the total amount the gymnast pays per month for his membership to the yoga studio, where:

y is the total cost per month, in dollars

x is the number of classes the gymnast attends per month

The equation has two parts:

The constant 20 represents the fixed monthly fee the gymnast pays, regardless of how many classes he attends.

The term 10x represents the additional fee the gymnast pays for each class he attends. Since the coefficient of x is 10, the gymnast pays $10 for each class he attends.

Therefore, if the gymnast attends x classes per month, his total monthly cost would be:

Total Cost = Monthly Fee + Cost per Class * Number of Classes

y = 20 + 10x

For example, if the gymnast attends 3 classes per month, his total monthly cost would be:

y = 20 + 10(3)

y = 20 + 30

y = 50

Therefore, the gymnast would pay a total of $50 per month for his membership to the yoga studio if he attends 3 classes per month.
