Answer:

Step-by-step explanation:

Multiply the numbers:

-5x*15x + 12x - 4x.

Which should get you: -75xx + 12x - 4x

Then combine exponents : -75xx + 12x - 4 = -75x^2 + 12x - 4x

Combine like terms: -75x^2 + 8x

Then find common factor with is -1

Lastly, rewrite in factored form : -1(75x^2 + 8x) = -1(75x - 8)x

Colin had $23 to spend on four raffle tickets after buying them had $11. So each raffle ticket cost is $3 and the equation is 4x + 11 = 23.

Colin had $23 to spend on four raffle tickets after buying them had $11

We have to determine how much each raffle ticket cost and the equation.

Let the cost of one raffle is x.

So the cost of four raffle is 4x.

Colin has total $23.

Colin has left money = $11

So the required equation should be

4x + 11 = 23

Now solving the equation

Subtract 11 on both side, we get

4x = 12

Divide by 4 on both side, we get

x = 3

The cost of one raffle is $3.

The linear equation for the coordinate points given is obtained as y = -3/2x + 19.5.

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The coordinate points for the lines are (11,3) and (7,9).

The slope-intercept form of an equation/function is - y = mx + b

To find the slope m use the formula -

(y2 - y1)/(x2 - x1)

Substituting the values in the equation -

[9 - 3]/[7 - 11]

(6)/(-4)

3/-2

So, the slope point is obtained as m = 3/-2.

The equation becomes - y = -3/2x + b

To find the value of b substitute the values of x and y in the equation -

3 = -3/2(11) + b

3 = -33/2 + b

b = 3 + 33/2

b = (6 + 33)/2

b = 39/2

b = 19.5

So, the value for b is 19.5.

Now, the equation becomes -

y = -3/2x + 19.5

The graph for the equation is plotted.

Therefore, the equation is obtained as y = -3/2x + 19.5.

Step-by-step explanation:

x= 24/3 = 8

Answer:

[tex] \sf \: x = 8[/tex]

Step-by-step explanation:

Given equation,

→ 3x = 24

Now the value of x will be,

→ 3x = 24

→ x = 24 ÷ 3

→ [ x = 8 ]

Hence, the value of x is 8.

Answer:

no solutions

Step-by-step explanation:

8(2w - 3) = 4(4w - 8)

Use distributive property.

16w - 24 = 16w - 32

subtract 16w from both sides.

-24 = -32

When the variable falls out of the equation as you are working on it, and you're left with a false statement, there is no solution.

Answer:

no solution

Step-by-step explanation:

to find the value of w, we have to isolate it on one side of the equation.

first, we distribute the numbers outside of the parentheses and multiply them to each term on the inside. this gives us:

16w - 24 = 16w - 32

next, we move 24 to the other side of the equation by adding 24 to both sides. by doing this, we get rid of 24 on the left side by making its value 0, and we add it to -32 on the right side. this gives us:

16w = 16w - 8

after this, we do the same with the 16w on the right side and subtract it from both sides. however, you might notice that there's a problem here.

when you try to move the 16w on the right side to the left side, you subtract 16w from itself, which gets rid of the variable entirely. whenever this happens, there are no values of the variable that make the equation possible- meaning that the answer is no solution.

hope this helped, good luck!

Answer:

18.19

Step-by-step explanation:

$ = linear f(t)

$16.03 = f(40) = fixed fee + per min fee = x + 40y

$19.72 = f(81) = fixed fee + per min fee = x + 81 y

use above 2 equations to minus the other

you get:

19.72-16.03 = 41y

so y = 0.09

so x = 16.03 - 40*0.09 =12.43

so for 64 mins

cost = 12.43 + 0.09*64 =18.19

The measure of angle m∠CBD is equal to 55°

We shall first find the measure of the angle m∠CDB so that we can evaluate for the measure of angle m∠CBD using the sum of interior angles of a triangle theorem as follows:

m∠ADB and m∠CDB are on a straight line and their sum is equal to 180° so;

m∠CBD + 80° = 180° {sum of angles on a straight line}

m∠CDB = 180° - 80° {subtract 80° from both sides}

m∠CDB = 100°

m∠BCD + m∠CDB + m∠CBD = 180° {sum of interior angles of a triangle}

25° + 100° + m∠CBD = 180°

125° + m∠CBD = 180°

m∠CBD = 180° - 125° {subtract 125° from both sides}

m∠CBD = 55°

In conclusion, the measure of angle m∠CBD is equal to 55°.

The angular momentum of an object can be calculated using the formula L = Iω, where L is the angular momentum, I is the moment of inertia, and ω is the angular velocity.

In the case of the ballet dancer, we are told that they are spinning at 1.5 rev/sec, and that they can be modeled as a cylinder with a moment of inertia of 22 MR^2, a mass of 62 kg, a height of 1.6 m, and a radius of 0.16 m.

We can calculate the moment of inertia of the cylinder using the formula I = (1/2) MR^2, where M is the mass and R is the radius.

Plugging in the values we have, I = (1/2)(62 kg)(0.16 m)^2 = 3.072 kg-m^2

We can then calculate the angular momentum of the dancer by plugging in the values we have into the formula L = Iω,

L = (3.072 kg-m^2)(1.5 rev/sec) = 4.608 kg-m^2/s

So the angular momentum of a ballet dancer who is spinning at 1.5 rev/sec, modeled as a cylinder with a moment of inertia of 22 MR^2, a mass of 62 kg, a height of 1.6 m and a radius of 0.16 m is 4.608 kg-m^2/s.

The volume of the piece is: 4489.33

To find the volume of this piece, we need to subtract the volume of the cylindrical hole from the volume of the sphere.

The volume of the sphere is given by the formula: V = (4/3) * pi * r^3

Where r is the radius of the sphere, so in this case: V = (4/3) * pi * (7cm)^3 = 1436 * 3.14 cm^3 = 4511.32 cm^3

The volume of the cylinder is given by the formula: V = pi * r^2 * h

Where r is the radius of the cylinder and h is the height of the cylinder, since the hole is drilled through the center of the sphere, the height of the cylinder is equal to the radius of the sphere, so: V = 3.14 * (1cm)^2 * 7cm = 21.99 cm^3

So the volume of the piece is: 4511.32 - 21.99 = 4489.33 cm^3
