Starting at 11:00 pm a bus makes a stop every 27 minutes. Also starting at 11:00pm a taxi makes a stop every 18 minutes. What is the next time there will be a bus and the taxi at the same place and the same time.

Answers

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

AAA Packages Plus sends packages overnight for $5 plus $0.25 per ounce. United Packages charges $2 plus $0.35 per ounce.

a) Mr. Molinari noticed that his package would cost the same to mail using either service. Write an equation to represent this situation.

b) How much does Mr. Molinari’s package weigh?

Answers

A.)
The equation for AAA packages plus would be .25x+5
The equation for United packages would be
.35x+2

B.) his package would need to be 30 ounces for them to be the same price

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.

What is a numerical expression?

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.

Sylvia and Patrick plotted the information they gathered on the weight of cars and the mileage they get. Then they each drew a line on the graph
that they felt best fit the data,
Sylvia's line blank
a line of best fit because her line blank .
Patrick's line blank
a line of best fit blank
as his line blank.

Answers

Answer:

The correct options are;

a) Is

b) Passes through the middle of the plotted scatter data points on the graph

b) Is not

e Does not pass through the middle of the plotted scatter data points on the graph

Step-by-step explanation:

Whereby the graph with the line of best fit on the left was drawn by Sylvia and the graph with the line of best fit on the right was drawn by Patrick, we have;

The line of best fit is a line that gives the relationship of the data points within a graph to each other, such that the line of best fit provides an approximation of the data on a graph

The line of best fit is the line that passes through the mid region of all the scatter points within a graph, and closeness of the data points on the scatter plot to the line of best fit, the higher the level of correlation between the line of best fit and the data.

Therefore, we have;

Sylva's line is a line of best fit because her line passes through the middle of the plotted scatter data points on the graph. Patrick's line is not a line of best fit as his line does not pass through the middle of the plotted scatter data points on the graph.

Answer: Sylvia’s line  is  a line of best fit because her line  is close to most of the data points . Patrick’s line  is not  a line of best fit as his line  is not close enough to all the data points .

If the maximum height of the tunnel is the same as its maximum width, 9.8 meters, determine a quadratic model to represent the tunnel.

State a geometric model that could be used to represent a truck passing through the tunnel. ​

Answers

Answer:

TUNNEL:

f(x) = -2/4.9  [tex]x^{2}[/tex]  + 9.8

TRUCK:

Width (m) < 9.8

Height (m) <  -2/4.9 ( [tex]Width^{2}[/tex] /4 - [tex]4.9^{2}[/tex] )

Step-by-step explanation:

Please see attachment

If the maximum height of the tunnel is the same as its maximum width, 9.8 meters, The quadratic model to represent the tunnel will be f(x)= (-2/4.9)x²+9.8.

What is a quadratic function?

Any function of the form[tex]\rm f(x) =ax^2+bx+c[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic function.

It is given that, If the maximum height of the tunnel is the same as its maximum width, 9.8 meters.

We have to determine a quadratic model to represent the tunnel.

The quadratic function is formed as,

f(x) =K(x-x₁)(x-x₂)

x₁=width/2

x₁=9.8/2 = 4.9

x₂= -x₁ = -4.9

Substitute the obtained value as,

f(x) = K(x-4.9)(x-(-4.9))

f(x) =K(x²-4.9²)

f(0)=9.8

The value of K is obtained as a result,

K=-2×4.9/(4.9)²

K= -2/4.9

Substitute the value of K as,

f(x) = -2/4.9(x²-4.9²)

f(x) = (-2/4.9)x²+2×4.9

f(x)= (-2/4.9)x²+9.8

Thus, if the maximum height of the tunnel is the same as its maximum width, 9.8 meters, The quadratic model to represent the tunnel will be f(x)= (-2/4.9)x²+9.8.

Which pairs of angles are congruent because they are vertical angles? Check all that apply. 4 lines intersect to form 14 angles. Angles 14 and 12, 11 and 13, 10 and 8, and 7 and 9 are vertical angles. Angle 1 and Angle 4 Angle 14 and Angle 12 Angle 7 and Angle 8 Angle 10 and Angle 8 Angle 3 and Angle 5 Angle 8 and Angle 12

Answers

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.

What is an angle?

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.

The angle between the incident ray and reflected ray is 90°. Calculate the angle of incidence and the angle of reflection.​

Answers

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°

The cost of a dvd in dollars can be represented by the expression 18-d where d is the discount amount. Use the distributive property to write and simplify an expression for the cost of 3 dvds

Answers

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

Suppose that the original price of a short is 40$ which is better 60% discount of a discount of 30 followed by a discount of 35

Answers

Answer:

60% discount is the better buy

Step-by-step explanation

Step one

Original price =$40

Let us compute the various discounts and compare the prices

For 60%

=60/100*40

=0.6*40

=$24

New price = 40-24= $16

For 35%

=35/100*40

=0.35*40

=$14

New price = 40-14= $26
