DO THE MATH: Billie offers a product for $40 with free shipping. But the shipping is in reality $15 per unit of the product sold. What is the actual selling price of the product, not including shipping costs?
$55
$35
$25
$15

Answers

To calculate the actual selling price of the product, not including shipping costs, we need to subtract the shipping cost from the offered price.

Given that the shipping cost is $15 per unit, the selling price without shipping can be calculated as follows:

Actual Selling Price = Offered Price - Shipping Cost

Actual Selling Price = $40 - $15

Actual Selling Price = $25

Therefore, the actual selling price of the product, not including shipping costs, is $25

A bag contains marbles of four different colors: 4 blue marbles 12 red marbles 8 green marbles 2 yellow marbles what is the probability of not picking a red marble out of the bag

Answers

Answer:

The total number of marbles in the bag is 4 + 12 + 8 + 2 = 26.

The probability of not picking a red marble out of the bag is equal to the number of marbles that are not red divided by the total number of marbles in the bag.

The number of marbles that are not red is 4 (blue) + 8 (green) + 2 (yellow) = 14.

Therefore, the probability of not picking a red marble out of the bag is 14/26 or 7/13.

So the probability of not picking a red marble is 7/13.

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 50 ft.
hl
What is the volume of the sphere?

Answers

The volume of a sphere can be calculated using the formula V = (4/3)πr³, where V is the volume and r is the radius.

Given that the sphere and the cylinder have the same radius and height, we can assume that the radius of both shapes is the same.

Let's denote the radius as 'r'. The volume of the cylinder is given as 50 ft³.

The volume of the cylinder is calculated using the formula V = πr²h, where h is the height.

Since the height of the cylinder is not given, we cannot determine the exact value of 'r' or calculate the volume of the sphere.

However, if we assume that the height of the cylinder is equal to its diameter (which is twice the radius), we can proceed with the calculation.

If the height of the cylinder is equal to 2r, the volume of the cylinder becomes:

50 = πr²(2r)

50 = 2πr³

Dividing both sides of the equation by 2π gives:

25 = πr³

Now, we can substitute this value of πr³ into the volume formula of the sphere:

V = (4/3)πr³

V = (4/3)(25)

V = 100/3

Therefore, if the height of the cylinder is equal to its diameter, the volume of the sphere would be 100/3 ft³. However, please note that this assumption might not necessarily be valid without further information about the relationship between the height and radius of the cylinder.

Answer: The Volume of the sphere is 100/3 cubic feet.

Step-by-step explanation:

It is clearly seen in the given figures, the height is two times the radius. Therefore, h is equal 2r.

We know that,

The volume of the sphere is π x r^2 x h. (r is radius and h is height)

So putting the values of height, h in the above formula, we get:

πxr^2x2r

= 2 * π * r^3.

= 2 * π * r^3 = 50

= π * r^3 = 25

We get, r^3 = 7.957747155

Therefore, r = 1.996472712

Now that we have the measure of the radius, we can find the volume of the sphere!

(4 / 3) * π * r^3

(4/3) * π * (1.996472712)^3

= (4/3) * π * 7.957747155

= (4/3) * π * (25 / π)

= (4/3) * 25

= 100/3 cubic feet.

Answer: let me explain!

Step-by-step explanation: So this might seem really confusing at first, but it’s actually suuuuuuper easy :P

So, if you think about it, every five seconds the amount of peanuts…well I don’t know how to explain it but let me show you this with numbers.
(4x2)x2x2x2 and so on. The number multiplies by two every five seconds from there. So figure out how many groups of five second there are in 100 seconds by dividing!

It’s 20!

So since 5 happens 20 times, and every time 5 happens, 2 happens, 2 also happens 20 times! (If that makes any sense)

So that answer would be 8x*twenty twos*

Which is…*drumroll please*

8,388,608
I even double checked!

And for the briefcase skeleton thing

She needs to try it 25 times because there are 5 books and each book can be switched with the other 4 times if the first one doesn’t work, therefore you need to multiply and the equation would be 5^2, or in other words, 25.

miriam is studying a type of plant that grows at a constant rate. Every month, she visits two of these plants and measures their heights. she made this table. Miriam want an equation she can use to find Plant A’s height in centimeters (a) given Plant AB’s height in centimeters (b).

Answers

The equation that represents the situation is a = b- 4.

Since the plant grows at a constant rate, we can assume that the height of the plant is increasing linearly with time.

Let's use the data from Week 1 and Week 2 to find the rate of growth for each plant:

For Plant A: Growth rate = (24 cm - 22 cm) / (2 weeks - 1 week) = 2 cm/week

For Plant B: Growth rate = (28 cm - 26 cm) / (2 weeks - 1 week) = 2 cm/week

Since the growth rate is constant, we can use the equation of a line to model the height of each plant over time:

For Plant A: a = 2t + b, where t is the time in weeks and b is the initial height of the plant.

For Plant B: b = 2t + c, where c is the initial height of Plant B.

We can find the values of b and c by substituting the data from Week 1 into these equations:

For Plant A: 22 = 2(1) + b, so b = 20.

For Plant B: 26 = 2(1) + c, so c = 24.

Now we can substitute these values into the equations for Plant A and Plant B:

Plant A: a = 2t + 20

Plant B: b = 2t + 24

To find an equation that gives Plant A's height in terms of Plant B's height, we can solve the equation for t in terms of b:

b = 2t + 24

2t = b - 24

t = (b - 24) / 2

Then we can substitute this expression for t into the equation for Plant A:

a = 2t + 20

a = 2[(b - 24) / 2] + 20

a = b - 24 + 20

a = b - 4

So the equation we were looking for is:

a = b - 4

Therefore, to find Plant A's height in centimeters given Plant B's height in centimeters, we simply subtract 4 from Plant B's height.

To calculate the maxHP values for levels 62-70 by plugging in the appropriate level values into the formula.

One way to extend the maxHP for levels beyond 60 is to use the same formula that was used to calculate the maxXP for levels 1-60, but with the appropriate values plugged in.

The formula for the maxHP for a given level can be approximated as:

maxHP = baseHP x  (1 + level/5)²

The coordinates for the center of the circle are (1/2, 1), and the length of the radius is 2 units. Option C is a correct choice.

To find the coordinates of the center of the circle and the length of the radius, we need to rewrite the equation of the circle in standard form, which is (x - h)² + (y - k)² = r². Here, (h, k) represents the coordinates of the center of the circle, and r represents the radius.

Given equation: x² + y² - x - 2y - 1 = 0

To convert it into standard form, we complete the square for the x and y terms separately.

Rearranging the equation:

x² - x + y² - 2y = 1

Completing the square for x:

(x² - x + 1/4) + (y² - 2y) = 1 + 1/4

Completing the square for y:

(x² - x + 1/4) + (y² - 2y + 1) = 1 + 1/4 + 1

Simplifying:

(x - 1/2)² + (y - 1)² = 9/4

Comparing it with the standard form, we can see that:

Center coordinates: (1/2, 1)

Radius: √(9/4) = 3/2 = 1.5 units

Therefore, the correct answer is C. The coordinates for the center of the circle are (1/2, 1), and the length of the radius is 2 units.

Which of the following equations represents a linear function?

x = 3
y = 3x2
y equals negative one third times x plus 1
3x − 4 = 7

Answers

The  Linear function is y equals negative one third times x plus 1

A linear function is a function that has a constant rate of change, meaning that as one variable (usually x) increases or decreases by a certain amount, the other variable (usually y) also changes by a constant amount.

Out of the four given equations, the only one that represents a linear function is the third one:

y equals negative one third times x plus 1

This is because the equation has a constant rate of change of -1/3 for any change in x. For example, if we increase x by 3, y will decrease by 1 (because 3*(-1/3) = -1). Similarly, if we decrease x by 3, y will increase by 1. This constant rate of change is what makes the equation represent a straight line when graphed.

The other three equations do not represent linear functions.

The first equation, x = 3, is not a function at all because there are multiple possible y values for the given x value of 3.

The second equation, y = 3x2, is a quadratic function because it contains an x2 term, which means that the rate of change of y with respect to x is not constant.

The fourth equation, 3x - 4 = 7, is a linear equation but not a function because for any given x, there is only one corresponding value of y. However, when the equation is solved for y, it becomes y = 3x - 3, which represents a linear function with a constant rate of change of 3.

Answers

a) Value of K is Option 3. 98.83%

b) It takes Option 2. 183 bounces for the ball to bounce back to a height of less than 3 inches (1/4 of a foot).

a) To determine k, we can use the formula for the nth term of a geometric sequence:

[tex]a_n[/tex] = [tex]a_1[/tex] * [tex]r^{(n-1)}[/tex]

where a_1 is the initial term, r is the common ratio, and n is the term number.

We know that [tex]a_1[/tex] = 10 feet and [tex]a_5[/tex] = 9.04 feet, so we can set up the equation:

[tex]a_5[/tex] = [tex]a_1[/tex] * [tex]r^{(5-1)}[/tex]

9.04 = 10 * [tex]k^4[/tex]

Solving for k, we get:

k = [tex](9.04/10)^{(1/4)}[/tex] = 0.9883 or 98.83%

Therefore, the answer is (Option 3) 98.83%.

b) We can use the formula for the nth term of a geometric sequence again to find the height of the ball after the nth bounce:

[tex]a_n[/tex] = 10 * [tex]k^{(n-1)}[/tex]

We want to find the smallest n such that a_n < 1/4 foot, or 0.25 feet. Substituting k = 0.9883, we get:

10 * [tex]0.9883^{(n-1)}[/tex] < 0.25

Solving for n, we get:

n > log(0.25/10) / log(0.9883) + 1

n > 183.3

Since n must be a whole number, the smallest n that satisfies this inequality is n = 184. Therefore, it takes 183 bounces for the ball to bounce back to a height of less than 3 inches (Option 2).

A noodles factory gives 10% commission to a wholesaler for selling its produtcs. After giving the commission to the wholesaler, the company recieves Rs 315000 in baishakh. Find the total sales of noodles by the wholesaler in baisakh.

Answers

To find the total sales of noodles by the wholesaler in Baishakh, we need to calculate the original amount before the commission was deducted.

Let's assume the total sales by the wholesaler in Baishakh is represented by 'x'.

The commission given to the wholesaler is 10% of the total sales, which can be expressed as 0.10x.

The amount received by the company after deducting the commission is Rs 315,000.

So, the equation becomes:
x - 0.10x = Rs 315,000

Simplifying the equation:
0.90x = Rs 315,000

Dividing both sides by 0.90:
x = Rs 350,000

Therefore, the total sales of noodles by the wholesaler in Baishakh is Rs 350,000.

Answer: 350000

Step-by-step explanation: Let the total sale of noodles by the wholesaler be x.

Given: Commission for the wholesaler is 10%

After receiving a 10% commission the company got rupees 315000.

x-10% of x =315000

x - 10\100 = 315000

x-x\10 = 315000

10x - 10\10 =315000

9x = 3150000

x= 3150000\9

x= 350000

Answer:

The volume of the figure is 76ft³.

Step-by-step explanation:

Divide the figure into 2 parts to make it easier to solve for the volume.

V1 = 6ft(2ft)(3ft)

V1 = 36ft³

V2 = 4ft(2ft)(5ft)

V2 = 40ft³

V = V1 + V2

V = 36ft³ + 40ft³

V = 76ft³

Answers

The correct graph of the inequality ( |x| + 3 > 3) is attached accordingly.

Here is how the above was solved

Recall that the absolute value (or modulus) of a real number x is its non-negative value regardless of its sign. For example, 5 has an absolute value of 5, and 5 has an absolute value of 5.

A number's absolute value can be conceived of as its distance from zero along the real number line.

So, given  |x| + 3 > 3

Add minus three to both sides

|x| + 3  + (-3) > 3 + (-3)

|x|  > 0

Thus, the absolute value of x is
