Explain how rays AB and AC form both a line and an angle.
A line with points C, A, B has arrows for endpoints.

Answers

Answer 1

Answer:

An angle is defined as two rays with a common endpoint, so CAB (or BAC) is an angle. A line is described as an infinite set of points that extend forever in either direction, which these rays also do.

Step-by-step explanation:

Angles are rays with a shared endpoint.

Lines extend forever in either direction.

Rays AB and AC extend forever in either direction.

Answer 2

A line with points C, A, and B with arrows at the endpoints can satisfy the fact that the two rays AB and AC form both a line and an angle.

A line with points C, A, and B have arrows on both endpoints.

We need to explain how the line containing the points C, A, and B has two rays AB and AC and how it can form both a line and an angle.

What are a line, ray, and angle?

A line has no endpoints, it extends infinitely in both directions and both end point is denoted by an arrow.

A ray has a fixed point on one side and an arrow on the other side which extends infinitely.

An angle is formed by two rays from one common fixed point.

Let us draw the line with points C, A, and B that have arrows at the endpoints.

C                A                      B

<----------------.-------------------->

We can say that AB is a ray since at point A we have a fixed point and at point B there is an arrow.

And AC is also a ray since at point A there is a fixed point and at point C there is an arrow.

The two rays AB and AC together form a line because on both ends sides there are arrows.

An angle can also be formed since AB and AC are two rays from one common fixed point.

Thus a line with points C, A, and B with arrows at the endpoints can satisfy the idea that the two rays AB and AC form both a line and an angle.

James is playing an arcade game with tokens. In the first
game, he hits the jackpot and doubles the number of
tokens that he has. In the second game, James wins 12
more tokens. In his third and final game, he loses 4
tokens. James now has 170 tokens. How many tokens
did he have before he started playing the game?

Answers

Answer

81 tokens

Step-by-step explanation:

x+12-4=170

x+8=170

 -8   -8

x=162

     162/2=81 tokens

The number of tokens he had before he started playing the game is 81 tokens.

Given,

James is playing an arcade game with tokens.

In the first game, he hits the jackpot and doubles the number of tokens that he has.

In the second game, James wins 12 more tokens.

In his third and final game, he loses 4 tokens. James now has 170 tokens.

We need to find how many tokens did he have before he started playing the game.

What does the term mean?

Doubles = multiply by 2

x more than M = M + x

Loses x from M = M - x

We have,

Let the number of tokens he had initially be M.

First game:

Doubles the number of tokens

= 2M

Second game:

James wins 12 more tokens.

=  2M + 12

Third game:

Loses 4 tokens.

= 2M + 12 - 4

= 2M + 8

James now has 170 tokens

This means:

2M + 8 = 170

2M = 170 - 8

2M = 162

M = 162 / 2

M = 81

Thus the number of tokens he had before he started playing the game is 81 tokens.

Explain how you know that they are all similar. b. Using the similar triangles you found in part (a), complete the following extended proportion (look at image)

Answers

Answer:

SImilar triangles are: ABC, DBG, DEF, and BEH.

Step-by-step explanation:

There are clealy four well defined triangles in the image:

ABC, DBG, DEF, and BEH.

Given the parallelism of the mentioned lines, one can conclude that when those lines parallel to different sides of the triangle ABC for example (to sides AC and CB), intersect, they will also intersect giving similar angles . That is: angle ACB  must equal angle DGB, angle DFE, and angle BHE. Apart from that, the angles around the bases of all four triangles must be equal since they come from parallel lines. That is:

(1) angles BAC, BDG, BDF, and EBH must be equal to each other, and

2) angles ABC, DBG, DEF, and BEH must be equal to each other.

Therefore we have four triangles with congruent angles, which make them similar triangles.

she earned in a savings account. The account earns 5.18% interest annually. If she does
not deposit or withdraw any money from for 18 months, how much will she have in her
account?

Answers

Answer:

$134.71

Step-by-step explanation:

This is a simple interest question

A = P(1 + rt)

A = Amount after t months or years

P = Principal or amount saved

r = interest rate = 5.18% = 0.0518

t = time.in years = 18 months

= 1 year and 6 month

= 1.5 year

A = $125( 1 + 0.0518 × 1.5)

A = $125 ( 1 + 0.0777)

A = $125(1.0777)

A = $134.71

Kevin and Randy Muise have a jar containing 100 ​coins, all of which are either quarters or nickels. The total value of the coins in the jar is ​$15.00. How many of each type of coin do they​ have?

Answers

Answer:

what do we know?

we know that a quarter is $0.25 and a nickel is $0.05

4x$.25 = $1

20x$0.05 = $1

and we have 84 coin

n = the number of nickels

q = the number of quarters

(1) n + q = 84 and

(2) 5*n + 25*q = 100*11.80 (always work in cents)

(3) 5*n + 25*q = 1180

Now substitute n from equation (1) into equation (3) and get

5*(84 - q) + 25*q = 1180

420 - 5*q + 25*q = 1180

20*q = 1180 - 420

20*q = 760

q = 38

Then using equation (1), plug in q

n + 38 = 84

n = 46

now check these values.

Is (.05*38 + .25*46 = 11.80)?

Is (2.30 + 9.50 = 11.80)?

Is (11.80 = 11.80)? Yes

Bacteria vary somewhat in size, but a diameter of 1.5 μ m is not unusual.
a. What would be the volume (in cubic centimeters) of such a bacterium, assuming that it is spherical? Express your answer using two significant figures.
b. What would be the surface area (in square millimeters) of such a bacterium, assuming that it is spherical? Express your answer using two significant figures.

Answers

Answer:

a) 1.8 × 10^-12 cm³ or 1.8 × 10^-12 cubic meters

b) 7.1 × 10^-6 mm² or 7.1 × 10^-6 square millimeters

Step-by-step explanation:

a) We are assuming that the shape of the bacteria is a sphere.

Hence, Volume of the Sphere(Bacteria) = 4/3 × π × r³

Diameter = 1.5 μm

Radius = Diameter/2 = 1.5μm/2

= 0.75μm

We are told that the volume should be in cubic centimeters

Converting 0.75μm to centimeters

1 μm = 1 × 10^-4 cm

0.75 μm =

Cross Multiply

= 0.75 μm × 1 × 10^-4 cm/ 1 μm

= 0.000075cm

Volume of the Sphere(Bacteria) = 4/3 × π × r³

= 4/3 × π × (0.000075)³

= 1.767145867 × 10^-12 cm³

Approximately as 2 significant figures = 1.8 × 10^-12 cm³

b) The formula for the Surface area of a Sphere = 4πr²

Diameter = 1.5 μm

Radius = Diameter/2 = 1.5μm/2

= 0.75μm

We are told that the surface area should be in square millimeters

Converting 0.75μm to millimeters

1 μm = 0.001 mm

0.75 μm =

Cross Multiply

= 0.75 μm ×0.001mm/ 1 μm

= 0.00075mm

Surface Area of a Sphere

= 4 × π × r²

= 4 × π × 0.00075²

= 7.06858 ×10^-6 mm²

Approximately to 2 significant figures

= 7.1 × 10^-6 mm²

The radiator in a car is filled with a solution of 70 per cent antifreeze and 30 per cent water. The manufacturer of the antifreeze suggests that for summer driving, optimal cooling of the engine is obtained with only 50 per cent antifreeze. If the capacity of the raditor is 4.7 liters, how much coolant (in liters) must be drained and replaced with pure water to reduce the antifreeze concentration to 50 per cent?

Answers

Answer:

0.94 liters antifreeze is  drained out and replaced with water to get a concentration to 50 per cent of the solution.

Step-by-step explanation:

Total amount of the solution is 4.7 liters.

It contains 70 percent antifreeze = 70% * of 4.7 = 3.29 liters of antifreeze

It contains 30 percent water = 30% * of 4.7= 1.41 liters water

For the solution to have 50 % antifreeze it must contain

4.7 * 50%= 2.35 antifreeze.

We have 3.29 liters and we want to have 2.35 liters of antifreeze

Therefore we will (3.29-2.35 =)0.94 liters drained out and replace it with water to get a concentration to 50 per cent.

La suma de los ángulos interiores de un dodecágono es: a) 1900 b) 1800 c) 1950 d) 1960 e) 2000

Answers

Answer:

La suma de los ángulos interiores de un dodecágono es 1800°

Step-by-step explanation:

Un dodecágono es un polígono (figura plana delimitada por lados rectos, creando una figura cerrada) formado por 12 lados, 12 vértices y por consiguiente, 12 ángulos interiores.

Los ángulos interiores de un polígono son los ángulos delimitados por dos lados y que se encuentran dentro del polígono.

Los polígonos convexos son aquellos en los cuales todos los ángulos del polígono miden menos de 180º y la suma de los ángulos interiores es determinada por el número de lados que posee el polígono de la siguiente manera: 180°*(n-2)

Entonces, la suma de los ángulos interiores de un dodecágono se calcula como: 180*(12-2)= 1800

La suma de los ángulos interiores de un dodecágono es 1800°

there are eight more women than men in a theater group. The group has a total of 44 members. How many men and how many women are in the group?

Answers

Answer: 26 women

Explanation:

Find how many men in the theatre:

(44 - 8)/2 = 36/2 = 18 men

But there are 8 more women than men in the theatre thus:

18 + 8 = 26 women

The number of men and women in the group will be 18 and 26 respectively.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that there are eight more women than men in a theater group. The group has a total of 44 members.

Let the number of men in the group be {x}. Then, the number of women will be (x + 8). We can write -

x + (x + 8) = 44

2x = 36

x = 18

Number of women : x + 8 = 26

The number of women in the group will be 26.

Therefore, the number of men and women in the group will be 18 and 26 respectively.

A truck with 20 inch diameter wheels is traveling at 45mi/hr

Find the angular speed of the wheels in rad/min,*hint* convert miles to inches & hours to minutes:
______rad/min

How many revolutions per minute do the wheels make?
______rpm

Show your work plzzzz

Answers

A wheel with a 20 in diameter has a circumference of 2π*(20 in) = 40π in.

For every 40π in traveled, a wheel makes one complete revolution, or turns an angle of 2π rad.

We need to convert from in to mi: there are 12 in to 1 ft, and 5280 ft to 1 mi, and so there are 12*5280 = 63,360 in to 1 mi.

We also need to convert h to min: there are 60 min to 1 h.

So we have an angular speed of

(45 mi/h) * ((2π)/(40π) rad/in) * (63,360 in/mi) * (1/60 h/min) = 2376 rad/min

As mentioned before, there are 2π rad to 1 rev, so

(2376 rad/min) * (1/(2π) rev/rad) ≈ 378.152 rev/min

(where rev/min is equivalent to rpm)

. Leah invested some money at 4.5% annual interest and $1000 more than four times that amount at 6%. Her total annual income from these two investments was $801. How much did she invest at each rate

Answers

Answer:

The amount invested are $2600 and $11400 respectively

Step-by-step explanation:

Let the first amount be x

Given:

(First Investment)

Principal (P1) = x

Rate (R1) = 4.5%

Time (T) = 1 year

(Second Investment)

Principal (P2) = 4x + 1000

Rate (R2) = 6%

Time (T) = 1 year

Income = $801

Calculating the income from the first investment;

[tex]I_1 = \frac{P_1R_1T}{100}[/tex]

Substitute values for P1, R1 and T

[tex]I_1 = \frac{x * 4.5 * 1}{100}[/tex]

[tex]I_1 = \frac{4.5x}{100}[/tex]

Calculating the income from the second investment;

[tex]I_2 = \frac{P_2R_2T}{100}[/tex]

Substitute values for P2, R2 and T

[tex]I_2 = \frac{(4x + 1000) * 6 * 1}{100}[/tex]

[tex]I_2 = \frac{6(4x + 1000)}{100}[/tex]

[tex]I_1 + I_2 = Annual\ Income[/tex]

So:

[tex]\frac{4.5x}{100} + \frac{6(4x + 1000)}{100} = 801[/tex]

Multiply through by 100

[tex]100 * \frac{4.5x}{100} +100 * \frac{6(4x + 1000)}{100} = 801 * 100[/tex]

[tex]4.5x +6(4x + 1000) = 801 * 100[/tex]

[tex]4.5x +24x + 6000 = 80100[/tex]

Collect Like Terms

[tex]4.5x +24x = 80100 - 6000[/tex]

[tex]28.5x = 74100[/tex]

Divide through by 28.5

[tex]x = \frac{74100}{28.5}[/tex]

[tex]x = \$2600[/tex]

Recall that; the second invest

Amount Invested = 4x + 1000

This gives

[tex]Amount = 4 * \$2600 + 1000[/tex]

[tex]Amount = \$11400[/tex]

Hence;

The amount invested are $2600 and $11400 respectively
