Step-by-step explanation:

The weight of small box and large box is 25pounds and 55 pounds respectively.

Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . Example of a Simultaneous equation include;

3x+2 = y equation 1

5x +3 = 2y equation 2

Represent the weight of small box by x and the weight of large box by y

x + y = 80 equation 1

70x + 60y = 5050 equation 2

therefore 70( 80-y) + 60y = 5050

5600 -70y +60y = 5050

-10y = 5050-5600

-10y = -550

y = -550/-10

y = 55 pounds

From equation 1

x +55 = 80

x = 80-55

x = 25 pounds

therefore the weight of small box is 25 pounds and the weight of large box is 55 pounds

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

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.

Step-by-step explanation:

(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 circumference of Circle B is 34.5 meters.

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.

Answer:

(0,8)

Step-by-step explanation:

The slope intercept formula is set up as y=mx+b, where b is the y-intercept value. In the equation y=3x+8, we can see that 8 is the y-intercept. So we plug 8 for y in a coordinate, and 0 for x. The answer is (0,8)

The intersection points are: (0, -3) and (10, 2)

The bounded area is -20.83 unit²

(a) The  intersection points of the line and curve are the points where the line and curve meet. Thus, the intersection points are:

(0, -3) and (10, 2)

(b) The integral terms of y which gives the area bound are:

a = -3, b = 2 (These are the y values of the intersection points)

Since we have x = y² + 3y and x = 2y + 6, we can say:

y² + 3y = 2y + 6

y² + 3y - 2y - 6 = 0

y² + y - 6 = 0

Thus, h(y) =

Using a = -3 and b = 2  with h(y) = y² + y - 6, we have the bounded area as:

[tex]Area = \int\limits^b_a {y} \, dy[/tex]

[tex]Area = \int\limits^{2}_{-3} {(y^{2} + y - 6}) \, dy[/tex]

Integrating the area:

Area = [y³/3 + y²/2 - 6y + C]²₋₃

Area = [2³/3 + 2²/2 - 6(2)] - [(-3)³/3 + (-3)²/2 - 6(-3)]

Area = [8/3 + 2 - 12] - [-9 + 4.5 + 18]

The range is easy to calculate and provides a quick estimate of how much variation there is in the dataset.

We have:

∠ABC + ∠ABD + ∠BDA + ∠BAC = 360°

120° + 115° + ∠BDA + ∠BAC = 360° (substituting given values)

∠BDA + ∠BAC = 125°

Now, we can use the law of cosines to relate the sides and angles in each triangle:

AC² = AB² + BC² - 2ABBCcos(∠ABC)

(4x-10)² = AB² + 24² - 2AB24cos(120°)

(4x-10)² = AB² + 576 + 24AB

AD² = AB² + BD² - 2ABBDcos(∠ABD)

40² = AB² + 24² - 2AB24cos(115°)

AB² - 48AB + 496 = 0

Using the quadratic formula to solve for AB, we get:

AB = (48 ± √(48² - 4×496))/2

AB = 24 ± 2√211

Since AB = 24 + 2x, we have:

24 + 2x = 24 + 2√211 or 24 - 2√211

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.

Perimeter = 2(length + width)

Step-by-step explanation:

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

What is globe?

A globe is a three-dimensional, spherical representation of the Earth or another celestial body, such as a planet or a moon. It is typically made of a hollow sphere of material, such as paper, plastic, metal, or glass, with a map of the Earth or the celestial body printed or drawn on its surface.

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. This calculation may be useful in a variety of contexts, such as designing packaging or calculating the capacity of a container.
