Using equations, we can find that the number of sale-priced songs is 5 and the number of regularly priced songs is 7.

Equations are mathematical statements with the equals (=) symbol and two algebraic expressions on either side. This illustrates the equality of the relationship between the expressions printed on the left and right sides. The formula LHS = RHS (left hand side equals right hand side) is utilised in all mathematical equations. To determine the value of an unknown variable that represents an unknown quantity, you can solve equations. A statement is not regarded as an equation if it has no "equal to" symbol.

As per the question, equation given are:

x + y = 12

x = 12 - y

Now, substituting the value in:

0.99x+1.25y = 13.7

= 0.99(12-y) +1.25y = 13.7

= 11.88 - 0.99y + 1.25y = 13.7

= 0.26y = 13.7 - 11.88

0.26y = 1.82

y = 1.82/0.26

y = 7

Now, substitute this value,

x = 12 - 7

x = 5

As a result, there are 5 songs on sale and 7 songs that are regularly priced.

Remains on her gift card:

$3.07

Step-by-step explanation:

15 - ((2*2.65) + (2*1.79) + (1*3.05))

= 15 - (5.3 + 3.58 + 3.05)

= 15 - 11.93

= 3.07

Answer:

$3.07

Step-by-step explanation:

Ms. Gantt has a $15 gift card to Starbucks.

She buys 2 muffins for $2.65 each, = 2 × 2.65 = $5.3

2 hot chocolates for $1.79 each, = 2 × 1.79 = $3.58

and a juice for $3.05. = 1 × 3.05 = $3.05

Now,

$15 - $5.3 - $3.58 - $3.05 = $3.07

Thus, $3.07 remains on her gift card

Using an exponential equation, it is found that 4 mg of the substance would still be left after 32 days.

The equation for the amount of the substance y after x half-lifes is given by:

\(y = a(0.5)^x\)

In this problem, the initial mass is of a = 64 mg.

Considering a half-life of 8 days, 32 days is equivalent to x = 32/8 = 4 half-lifes, hence:

\(y = 64(0.5)^4 = 4\)

4 mg of the substance would still be left after 32 days.

Answer:

347 meters

Step-by-step explanation:

To calculate the distance Billy has cycled, we need to find the circumference of his bike's wheels and multiply it by the number of revolutions.

The circumference of a circle can be found using the formula: C = πd, where C is the circumference and d is the diameter of the circle.

Given that the diameter of Billy's bike wheels is 85 cm, we can find the circumference:

C = πd

C = π * 85 cm

C ≈ 267.2036 cm

Now, to find the distance Billy has cycled, we multiply the circumference by the number of revolutions:

Distance = C * number of revolutions

Distance = 267.2036 cm * 130 revolutions

Distance ≈ 34716.468 cm

Converting the distance to meters:

Distance ≈ 347.16468 meters

Therefore, Billy has cycled approximately 347 meters.

Step-by-step explanation:

Consider this example first: Suppose the circumference of your bike tire is a nice easy number like 3ft.

If you're riding your tire and it rotates once, how far have you gone? 3ft

If it rotates twice, how far have you gone? 6ft

If it rotates four times, how far have you gone? 12ft

What if it rotates ten times?

Or 57 times?

How are you figuring this out?

You're multiplying the circumference by the number of revolutions.

In this problem, you know your tires make 150 revolutions. To find out how far it has gone, you need to know their circumference.

If you are given the diameter of the circle, the circumference is always going to be π times that diameter.

They tell you that the diameter of your tire is 85 cm. This means that the circumference of your tire must be 85π cm.

To find out how far you've traveled in cm, multiply this by the number of revolutions:

150 x 85π cm = 12750π cm

There are 100 cm in a meter, so divide this number by 100 to get the same distance in meters:

127.5π m

The distance between the points C(−6, −4) and D(6, 2) will be 13.42 units.

It is the measure of distance between the two points and is known as length. The length is measured in meters generally.

Let one point be (x, y) and another point be (h, k). Then the distance between the points will be given as,

D² = (x - h)² + (y - k)²

The points are C(−6, −4) and D(6, 2). Then the distance between them is calculated as,

D² = (6 + 6)² + (2 + 4)²

D² = 12² + 6²

D² = 144 + 36

D² = 180

D = 13.42 units

Step-by-step explanation:

The tube consists of a cylinder with a smaller cylinder removed from its center. We can find the volume of the tube by subtracting the volume of the smaller cylinder from the volume of the larger cylinder.

The volume of the larger cylinder is given by the formula:

V1 = πr^2h

where r is the radius and h is the height (or length) of the cylinder. Substituting the given values, we get:

V1 = π(3 cm)^2(20 cm) ≈ 565.49 cm^3

The volume of the smaller cylinder is also given by the formula:

V2 = πr^2h

where r is the radius (which is 1 cm in this case, since the diameter of the smaller cylinder is 2 cm less than the diameter of the larger cylinder) and h is the height (or length) of the cylinder (which is the same as the height of the larger cylinder). Substituting the given values, we get:

V2 = π(1 cm)^2(20 cm) ≈ 62.83 cm^3

Therefore, the volume of the tube is:

V = V1 - V2 ≈ 502.7 cm^3 (rounded to the nearest tenth)

Therefore, the volume of the tube is approximately 502.7 cubic centimeters.

Step-by-step explanation:

To determine the change in angular momentum (ΔL) of a cylinder from t = 0 to t = t0, a student can use the equation:

ΔL = I * Δω

where ΔL is the change in angular momentum, I is the moment of inertia of the cylinder, and Δω is the change in angular velocity.

To calculate Δω, the student needs to know the initial and final angular velocities, ω0 and ωt0, respectively. The change in angular velocity can be calculated as:

Δω = ωt0 - ω0

Once Δω is determined, the student can use the moment of inertia (I) of the cylinder to calculate ΔL using the equation mentioned earlier.

The moment of inertia (I) depends on the mass distribution and shape of the cylinder. For a solid cylinder rotating about its central axis, the moment of inertia is given by:

I = (1/2) * m * r^2

where m is the mass of the cylinder and r is the radius of the cylinder.

By substituting the known values for Δω and I into the equation ΔL = I * Δω, the student can calculate the change in angular momentum (ΔL) of the cylinder from t = 0 to t = t0.

It's important to note that this method assumes that no external torques act on the cylinder during the time interval. If there are external torques involved, the equation for ΔL would need to include those torques as well.

Complete question :

A pair of $36 jeans were on sale at Jim's Jeans for 1/3 off. The same pair of jeans were $42 at David's Denims. The jeans were on sale for 2/3 off.

A.) which store had the better buy

B.) how much will you pay at the store that has the better buy

Answer:

A.)David's denim has the better buy

B.) $14

Step-by-step explanation:

Jim's Jean store :

Cost of Jean = $36

Discount = 1/3 off

Discounted cost = $36 - (1/3 * $36)

Discounted cost = $36 - $12 = $24

David's Denim:

Cost of Jean = $42

Discount = 2/3 off

Discounted cost = $42 - (2/3 * $42)

Discounted cost = $42 - $28 = $14

David's denim has the better buy with a discounted price lower than the discounted price at Jim's store.

Cost at store with the better buy is $14

The given lines of equations are not perpendicular to each other. Therefore, `θ = cos⁻¹(8/(4√10))` which is approximately `28.07°`.Since `θ ≠ 90°`, the given lines of equations are not perpendicular to each other.

Given lines of equations:

x = −2 + 2t, y = −6, z = 2 + 6tx=−1+t,y=1+t,z=t, t∈ R.

Firstly, we need to find the direction vectors of the two given lines.For the first equation,Let `t=1`, then the point on the line is `(-2+2(1), -6, 2+6(1))`=`(0, -6, 8)`.

Let `t=2`, then the point on the line is

\(`(-2+2(2), -6, 2+6(2))`=`(2, -6,\)14)`.T

herefore, direction vector `

\(v1 = (2, -6, 14)-(0, -6, 8)`=`(2, 0, 6)`\)

For the second equation, direction vector \(`v2 = (1, 1, 1)`.\\\)

Let the angle between the direction vectors `v1` and `v2` be `θ`.

Then, we know that `v1 • v2 = |v1||v2| cosθ`, where `•` represents the dot product of the vectors, and `|.|` represents the magnitude of the vector.

Thus, we have:

(2, 0, 6) • (1, 1, 1) = √(2²+0²+6²)√(1²+1²+1²) cosθ

=> 8 = √40√3 cosθ=> cosθ = 8/(4√10)

Therefore,

`θ = cos⁻¹(8/(4√10))`

which is approximately `28.07°`.

Since `θ ≠ 90°`, the given lines of equations are not perpendicular to each other.
