Based on Cameron's current music service fees, the number of songs that would make the new service a less expensive option is 101 songs

The expression for the new service assuming the number of songs is x is:

= 15 + 0.80x

The expression for Cameron's current service is:
= 0.95x

Equating them gives:

0.95x = 15 + 0.8x

0.95x - 0.8x = 15

0.15x = 15

x = 100 songs

The cost will be the same at 100 songs so the new service would be cheaper at 101 songs.

4.7 * 10 ^9

Step-by-step explanation:

4,700,000,000

Scientific notation is of the form

a * 10 ^b  where a is a number between 1 and less than 10

Move the decimal so that it is a number between 1 and less than 10

4,700,000,000  becomes 4.700000000  and we moved the decimal 9 places to the left  b is +9  ( positive because we moved to the left)  We can drop the extraneous zeros

The side length of the rotated square is 9.22 units, and the area of the square is 85 square units.

To find the side length of the square, we can use the distance formula between two points in a coordinate plane. The distance formula is given by:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

In this case, the coordinates of the two adjacent corners of the square are (-4, -8) and (2, -1). Let's calculate the distance between these two points:

d = √((2 - (-4))² + (-1 - (-8))²)

 = √((2 + 4)² + (-1 + 8)²)

 = √(6² + 7²)

 = √(36 + 49)

 = √85

 ≈ 9.22

Therefore, the side length of the square is approximately 9.22 units.

To find the area of the square, we can use the formula:

Area = side length²

Plugging in the side length we calculated earlier:

Area = 9.22²

    ≈ 85 square units

Thus, the area of the square is approximately 85 square units.

Large cat's meal tastes more like tuna fish

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

Zane's cat loves tuna fish

so he adds 2 ounces of tuna fish to 10 ounces of cat food for small cat

and he adds 3 ounces of tuna fish to 12 ounces of cat food for large cat

to know whose meal tastes as tuna fish calculate their percentages

for small cat 2% is added to 10%

that means (2/12)*100=16.6

for large cat 3% is added to 12%

that means (3/15)*100=20

by this we can conclude that, large cat's meal tastes more like tuna fish

The numbers 13, left-handedness, and spirals on cacti hold some interesting characteristics and connections.

In various cultures and belief systems, the number 13 is often considered to be significant or symbolic. Some see it as unlucky, while others view it as a number of transformation or completion. For example, there are 13 lunar cycles in a year, and in some traditions, 13 is associated with the Goddess and feminine energy.

Left-handedness refers to a preference or dominance for using the left hand over the right hand. It is relatively less common than right-handedness in humans, with only about 10% of the population being left-handed. Left-handedness has often been associated with uniqueness, creativity, and different ways of thinking.

We can find the bat's wholesale cost by working backwards -

Do $41 - 9 to get $32, then we can divide the 32 by the 4 to get $8.

Therefore, the wholesale cost of the bat is $8.

Happy to help!

Answer:

The bat's wholesale cost is $8

Step-by-step explanation:

You first have to subtract 9 from 41 as that will be 4 times the wholesale cost, which is $32. Then you have to divide 32 by 4, as we want to get the wholesale cost, not 4 times of the wholesale cost, and this would give us the wholesale cost, which is $8.

The level of production that yields the maximum profit is 65 units, and the maximum profit is $3225. To get the level of production that yields maximum profit and the maximum profit for the commodity with the profit function p(x) = 130x - x^2 - 1000, follow these steps:

Step 1: Determine the derivative of the profit function with respect to x.
p'(x) = d(130x - x^2 - 1000)/dx = 130 - 2x
Step 2: Set the derivative equal to zero to find the critical points.
130 - 2x = 0
Step 3: Solve for x to find the level of production.
2x = 130
x = 65 units
Step 4: Evaluate the profit function at the critical point to find the maximum profit.
p(65) = 130(65) - 65^2 - 1000 = 8450 - 4225 - 1000 = $3225

The ordered rational numbers representing the gauge readings from least to greatest are 19/10, 63/10, 78/10, 78/10, 13/1, 25/1, 2/1.

To represent the gauge readings as rational numbers, we can express them as fractions with a common denominator.

Given readings:

25 psi pressure

13 psi vacuum

6.3 psi vacuum

7.8 psi vacuum

1.9 psi vacuum

2 psi pressure

7.8 psi pressure

Expressed as rational numbers with a common denominator:

25 psi = 25/1

13 psi = 13/1

6.3 psi = 63/10

7.8 psi = 78/10

1.9 psi = 19/10

2 psi = 2/1

7.8 psi = 78/10

Now, let's order these rational numbers from least to greatest:

1.9 psi = 19/10

6.3 psi = 63/10

7.8 psi = 78/10

7.8 psi = 78/10

13 psi = 13/1

25 psi = 25/1

2 psi = 2/1

Ordered from least to greatest:

19/10, 63/10, 78/10, 78/10, 13/1, 25/1, 2/1

Therefore, the ordered rational numbers representing the gauge readings from least to greatest are 19/10, 63/10, 78/10, 78/10, 13/1, 25/1, 2/1.

Answer:

The Laplace transform of f(t) is (3/s^2) e^(-s) - (2/s) + (1/s^2).

Step-by-step explanation:

We use the definition of the Laplace transform:

L{f(t)} = ∫[0,∞) e^(-st) f(t) dt

For f(t) = t, 0 ≤ t < 1, we have:

L{t} = ∫[0,1] e^(-st) t dt

Integrating by parts with u = t and dv = e^(-st) dt, we get:

L{t} = [-t*e^(-st)/s] from 0 to 1 + (1/s) ∫[0,1] e^(-st) dt

L{t} = [-e^(-s)/s + 1/s] + (1/s^2) [-e^(-s) + 1]

L{t} = (1/s^2) - (e^(-s)/s) - (1/s) + (1/s^2) e^(-s)

For f(t) = 2-t, t ≥ 1, we have:

L{2-t} = ∫[1,∞) e^(-st) (2-t) dt

L{2-t} = (2/s) ∫[1,∞) e^(-st) dt - ∫[1,∞) e^(-st) t dt

L{2-t} = (2/s^2) e^(-s) - [e^(-st)/s^2] from 1 to ∞ - (1/s) ∫[1,∞) e^(-st) dt

L{2-t} = (2/s^2) e^(-s) - [(e^(-s))/s^2] + (1/s^3) e^(-s)

Combining the two Laplace transforms, we get:

L{f(t)} = L{t} + L{2-t}

L{f(t)} = (1/s^2) - (e^(-s)/s) - (1/s) + (1/s^2) e^(-s) + (2/s^2) e^(-s) - [(e^(-s))/s^2] + (1/s^3) e^(-s)

L{f(t)} = (3/s^2) e^(-s) - (2/s) + (1/s^2)

Therefore, the Laplace transform of f(t) is (3/s^2) e^(-s) - (2/s) + (1/s^2).

There are 1,108,600 ways to choose a focus group of three students where all three students do not come from the same major.

Combination formula:

C(200, 3) = 200! / (3! × 197!)

= 1313400

Number of ways to choose three students who all come from the same major.

Business: C(100, 3) = 161700

Math: C(60, 3) = 34220

Psych: C(40, 3) = 9880

So the total number of ways to choose three students who all come from the same major

= 161700 + 34220 + 9880

= 204800

Subtract this from the total number of ways to choose three students to get the number of ways to choose three students where they don't all come from the same major

= 1313400 - 204800

= 1108600
