Answer:

54 - 3d

Step-by-step explanation:

In order to find the cost of 3 DVDs we would simply need to multiply the expression given by 3. In order to do so we must use the distributive property and distribute the 3 to both the initial price of the dvd and the discount price, like so...

3(18 - d)  ... in order to distribute we multiply 3 by 18 and then by d seperately

(3 * 18) - (3 * d)

54 - 3d

That would leave us the expression 54 - 3d

Answer:

Step-by-step explanation:

The angle of incidence and reflection is 45°

The angle between them is 90°

they lie on the same plane, and angle of incidence = angle of reflection

the sum of all the angles is 180°

let angle of incidence and reflection be x

therefore,

90 + 2x = 180

x = 45°

Given:

Cost of small candles = $4.00

Cost of large candles = $6.00

They have at most 50 candles, and want to make at least $100.

To find:

The system of linear inequalities represents the situation.

Solution:

Let x be the number of small candles and y be the number of large candles.

At most 50 candles means total candles must be less than or equal to 50.

[tex]x+y\leq 50[/tex]

Want to make at least $100. It means, the total sales must be greater than or equal to $100.

[tex]4x+6y\geq 100[/tex]

Therefore, the inequalities in the system of linear inequalities are [tex]x+y\leq 50[/tex] and [tex]4x+6y\geq 100[/tex].

a. The equation that both services would cost the same is

0.25x + 5 = 0.35x + 2.

b. The weight of Mr. Molinary's package is 30 ounces.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, AAA Packages Plus sends packages overnight for $5 plus $0.25 per ounce.

United Packages charges $2 plus $0.35 per ounce.

Assuming the no. of ounces to be x.

∴ 0.25x + 5 = 0.35x + 2.

0.25x - 0.35x = 2 - 5.

- 0.1x = - 3.

x = 3/0.1

x = 30 ounces.

Answer:

◽Angle 14 and Angle 12

◽Angle 10 and Angle 8

Step-by-step explanation:

Vertical angles are opposite to each other on a pair of intersecting lines.

◽Angle 1 and Angle 4

These angles are not on the same two intersecting lines.

◽Angle 14 and Angle 12

These angles are on the same two intersecting lines. They are also opposite to each other.

◽Angle 7 and Angle 8

These angles are on the same intersecting lines, but they are not opposite to each other.

◽Angle 10 and Angle 8

They are on the same pair on lines, and opposite to each other.

◽Angle 3 and Angle 5

They are not on the same pair of intersecting lines.

◽Angle 8 and Angle 12

These angles are not on the same pair on intersecting lines. (However, they are also equal because they are corresponding, on the insides of an "F" pattern).

The pairs of angles are congruent because they are vertical angles that will be ∠14 & ∠12, ∠11 & ∠13, ∠10 & ∠8, and ∠7 & ∠9. Then the correct option is A.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

Vertically opposite angle - When two lines intersect, then their opposite angles are equal.

By the vertical angle property, then we have

∠14 = ∠12

∠10 = ∠8

∠7 = ∠9

∠11 = ∠13

The pairs of angles are congruent because they are vertical angles that will be ∠14 & ∠12, ∠11 & ∠13, ∠10 & ∠8, and ∠7 & ∠9. Then the correct option is A.

Answer:

$9450

Step-by-step explanation:

Given that:

The price of the home = $450000

The interest = 7.8%

Down payment = 30% of price of the home

i.e 0.3 × 450000 = 135000

The principal outstanding balance = 450000 - 135000

= 315000

Finally, the cost of 3 points will be;

Answer:

11:54pm

Step-by-step explanation:

Key details in the Question:

- Starting at 11:00 pm a bus makes a stop every 27 minutes.

- starting at 11:00pm a taxi makes a stop every 18 minutes.

The task is to find the time in which both the bus and taxi would make a stop.

Since the taxi has the shorter duration for a stop, we would use it as the basis for our calculations.

During the first taxi stop - 11:18pm

The Bus has not yet made its stop.

During the second taxi stop - 11:36pm

The Bus has made it's first stop (11:27pm) but is currently on the road.

During the third taxi stop - 11:54pm

The Bus would also be making it's second stop

The values of x = 5 and pq = 86.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 12 + 2 = 14

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 12 -2 = 10

* Multiplication operation: Multiplies values on either side of the operator

For example 12*2 = 24

Given that m is the midpoint of pq,

pm= 9x+3 and mq= 11x-17

⇒ 9x + 3 = 11x - 7

⇒ 3 = 11x - 9x -7

Rearrange the likewise terms and apply the arithmetic operations,

⇒ 3 = 2x - 7

⇒ 10=2x

⇒ x = 10/2

Divided by 2

⇒ x = 5

⇒ pq = 20x-14

⇒ pq = 20*5-14

⇒ pq = 86

Hence, the value of pq is 86.

[tex]y = \frac{1}{9}x+5\\\\9y = x+45\\\\9y-45 = x\\\\-45 = x-9y\\\\x-9y = -45\\\\[/tex]

The last equation is in the form Ax+By = C where A = 1, B = -9, C = -45

In the second step, I multiplied each term by 9 to clear out the fraction.

Understanding:

First, let's try simplifying the first equation as much as we can. As you know, you can add, subtract, multiply, divide, etc on both sides of the equation and it will remain the same value. To simplify [tex]3x-5=16[/tex] we can simply add 5 to both sides to cancel the -5 on the left-hand side. That will give us [tex]3x-5 +5=16+5[/tex], notice we added the 5 to both sides. The +5 cancels -5 and 16+5 is 21, which evaluates to [tex]3x=21[/tex]. And this equation looks familiar, it's our second equation actually. That's why both equations are the same, and in that x value that makes the first equation true, it will also do the same for the second equation. If you want to actually find the value of x which makes the equation true, you can simply divide the 21 on the right-side by 3 to make x coefficient equal to 1, [tex]\frac{3x}{3} =\frac{21}{3}[/tex], and that gives us,  [tex]x=7[/tex]. When x is 7 both equations are true.

Answer:

We conclude that the second equation must also be true for the same value of x because the value x = 7 satisfies the 2nd equation too.

Step-by-step explanation:

Given the first equation

[tex]3x-5=16[/tex]

Add 5 to both sides

[tex]3x-5+5=16+5[/tex]

simplify

[tex]3x=21[/tex]

Divide both sides by 3

[tex]\frac{3x}{3}=\frac{21}{3}[/tex]

simplify

[tex]x=7[/tex]

Thus, x = 7 is a value that satisfies the first equation.

Now, put x = 7 in the 2nd question to check whether x = 7 satisfies the equation or not.

3x = 21

3(7) = 21         ∵ x = 7

21 = 21

Thus, x = 7 also satisfies the 2nd equation.

Therefore, we conclude that the second equation must also be true for the same value of x because the value x = 7 satisfies the 2nd equation too.

Answer:

(f О g)(25) is -135

Step-by-step explanation:

The composite function (f О g)(x) means substitute x in f by g

∵ f(x) = -2x² - 7

∵ g(x) = √3 + 3

→ To find (f О g)(25), find g(25) first, then substitute x in f by the value of g(25)

∵ x = 25

∴ g(25) = √25 + 3

∵ √25 = 5

∴ g(25) = 5 + 3

∴ g(25) = 8

→ Now substitute x in f by 8

∵ x = 8

∴ f(8) = -2(8)² - 7

∴ f(8) = -2(64) - 7

∴ f(8) = -128 - 7

∴ f(8) = -135

∴ (f О g)(25) = -135

Answer:

at the top of the mountain or hill

Step-by-step explanation:

potential energy is stored energy so therefore the higjestpoint will have the most potential energy.

The skier begins at an elevated position, thus possessing a large quantity of potential energy (i.e., energy of vertical position).

The energy an object has as a result of motion is known as kinetic energy. A force must be applied to an object in order to accelerate it. We must put in effort in order to apply a force. After the work is finished, energy is transferred to the item, which then moves at a new, constant speed.

The skier has a lot of potential energy because they are starting from an elevated position (i.e., energy of vertical position).

If the skier is starting from rest, all of their mechanical energy is potential energy.

and, Potential energy is lost and kinetic energy, or the energy of motion, is acquired as the skier starts the ascent down the hill.
