Answer 1

Answer:

x = 15

y = 12

m < AED = 83°

m < DEC = 97°

Step-by-step explanation:

According to the given problem:

< AED = (6x - 7)°

< BEC = (4x + 23)°

< AEB = (8y + 1)°

< DEC = (5y + 37)°

Two angles are vertical angles if they are opposite angles formed by the intersection of two lines. Vertical angles are congruent.

Given that < AED and < BEC are vertical angles, then it means that they have the same measure.

The same goes with < AEB and <DEC, they are also considered as vertical angles.

To solve for x:

< AED = < BEC

(6x - 7)° = (4x + 23)°

Subtract 4x from both sides:

6x - 4x - 7 = 4x - 4x + 23

2x - 7 = 23

Add 7 to both sides:

2x - 7 + 7 = 23 + 7

2x = 30

Divide both sides by 2 to solve for x:

2x/2 = 30/2

x = 15

To solve for y:

< AEB = <DEC

(8y + 1)° = (5y + 37)°

Subtract 5y from both sides:

8y - 5y + 1 = 5y - 5y + 37

3y + 1 = 37

Subtract 1 from both sides:

3y + 1 - 1 = 37 - 1

3y = 36

Divide both sides by 3 to solve for y:

3y/3 = 36/3

y = 12

To double check whether our values of x and y are correct, substitute these values into the established equality statements:

< AED = < BEC

(6x - 7)° = (4x + 23)°

[6(15) - 7]° = [4(15) + 23]°

(90 - 7)° = (60 + 23)°

83° = 83° (True statement. Therefore, x = 15 is the correct answer, and m < AED = 83°).

< AEB = <DEC

(8y + 1)° = (5y + 37)°

[8(12) + 1)° = [5(12) + 37]°

(96 + 1)° = (60 + 37)°

97° = 97° (True statement. Therefore, y = 12 is the correct answer, and m < DEC = 97°).

A motorboat can maintain a constant speed of 47 mph relative to the water. The boat makes a trip upstream to a certain point in 51 minutes; the return trip takes 43 minutes. What is the speed of the current?

Answers

9514 1404 393

Answer:

  4 mph

Step-by-step explanation:

The ratio of speeds upstream and down is inversely proportional to the ratio of times upstream and down. If we let c represent the speed of the current, the relation can be written ...

  (47 +c)/(47 -c) = 51/43

  43(47 +c) = 51(47 -c)

  94c = 8(47) . . . . . . . . . . . add 51c -43(47)

  c = 4 . . . . . divide by 94

The speed of the current is 4 miles per hour.

Part 1: Graph a function when give the following Domain and Range:​

Answers

Answer:

Step-by-step explanation:

This is basically the same thing as the last question.

The domain goes from - 8 to 5. The 5 has an open circle for it's endpoint < does not include the end point

the range is a little tricky. It goes from - 6  to 9. The -6 is has a circle (because it is not included in the answer). I'm not sure how you show that on a graph.

I think the best answer is this: if either the domain or range is separated by < then you must change the one that uses ≤ into < so the endpoints of the domain are in agreement. You cannot have the domain using < when the range uses ≤. They both must be the same. I think the best choice is<

Answer:

Step-by-step explanation:

A washer and a dryer cost $959 combined. The washer costs $59 more than the dryer. What is the cost of the dryer?

Answers

Answer:

A dryer costs $450.

A washer costs $509.

Step-by-step explanation:

Let:

"washer" = x

"dryer" = y

Set the equations:

x + y = 959

x = y + 59

First, plug in y + 59 for x in the first equation for x:

x + y = 959

(y + 59) + y = 959

Simplify, combine like terms:

y + y + 59 = 959

2y + 59 = 959

Next, isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis, Exponents (& Roots), Multiplications, Divisions, Additions, Subtractions.

First, subtract 59 from both sides of the equation:

2y + 59 (-59) = 959 (-59)

2y = 959 - 59

2y = 900

Next, divide 2 from both sides of the equation:

(2y)/2 = (900)/2

y = 900/2

y = 450

Next, plug in 450 for y in one of the equations:

x = y + 59

x = (450) + 59

x = 509

Check:

x + y = 959

450 + 509 = 959

959 = 959 (True).

~

Answer:

$450

Step-by-step explanation:

1. First, let's make a system of equations:

[tex]y+59=x,x+y=959[/tex] (y = dryer, x = washer)

2. (Solving)

Solve y + 59 = x for y:

[tex]y + 59 = x[/tex] [tex]y + 59-59=x-59[/tex] (Subtract 59 from both sides)[tex]y = x-59[/tex]

Substitute x - 59 for y in x + y = 959

[tex]x + y = 959[/tex] [tex]x+x-59=959[/tex] [tex]2x - 59 = 959[/tex] [tex]2x - 59 + 59 = 959 + 59[/tex] (Add 59 to both sides)[tex]2x = 1018[/tex] [tex]\frac{2x}{2} = \frac{1018}{2}[/tex] (divide both sides by 2)[tex]x = 509[/tex]

Substitute 509 for x in y = x - 59

[tex]y = x - 59[/tex] [tex]y = 509-59[/tex] [tex]y = 450[/tex]

Therefore, the dryer costs $450. (The washer costs $509).

Jasmine is a receptionist at a doctors office. She books 36 appointments each day . Four out of every 24 appointments are cancelled. How many appointments are cancelled each day?

Answers

If Jasmine books 36 appointments each day, 6 appointments will be canceled.

Number of appointments booked each day = 36 appointments

Since four out of every 24 appointments are canceled. This means the fraction of appointments that are canceled will be:

= 4/24 = 1/6

Now, since three are 36 appointments each day, the number of appointments that are canceled will be:

= 1/6 × 36

= 6 appointments

In conclusion, 6 appointments will be canceled each day.

Answer:  [tex]\frac{37}{1,101,716,330}\\\\[/tex]

This is the same as writing 37/1101716330

======================================================

Explanation:

Let's say the nine winning numbers are: 1,2,3,4,5,6,7,8,9

Let's further say that if we matched everything from 1 to 8, then we'll win second prize. That ninth value can be anything but 9. So we could have something like one of these examples

1,2,3,4,5,6,7,8,101,2,3,4,5,6,7,8,111,2,3,4,5,6,7,8,12

As you can see, there are 46-9 = 37 different choices we can have for that last slot. In other words, there are 37 items in the set {10,11,12,...,45,46} we can pick for that last ninth slot. Note that 46-10+1 = 37. This value will form the numerator of the answer.

------------------------------------------

Now to calculate how many ways there are to select the nine values regardless if we win or lose.

Since order doesn't matter, we use the nCr combination formula.

[tex]_{n} C _{r} = \frac{n!}{r!*(n-r)!}\\\\_{46} C _{9} = \frac{46!}{9!*(46-9)!}\\\\_{46} C _{9} = \frac{46!}{9!*37!}\\\\_{46} C _{9} = \frac{46*45*44*43*42*41*40*39*38*37!}{9!*37!}\\\\[/tex]

[tex]_{46} C _{9} = \frac{46*45*44*43*42*41*40*39*38}{9!} \ \text{ ... the ``37!'' terms cancel}\\\\_{46} C _{9} = \frac{46*45*44*43*42*41*40*39*38}{9*8*7*6*5*4*3*2*1}\\\\_{46} C _{9} = \frac{399,790,821,830,400}{362,880}\\\\_{46} C _{9} = 1,101,716,330\\\\[/tex]

There are slightly over 1 billion ways to select the nine values.

This large value is the denominator of our answer which is [tex]\frac{37}{1,101,716,330}\\\\[/tex]

The 37 up top represents the number of ways to win the second prize we're after, while the massive number in the denominator represents how many ways there are to play the game.

------------------------------------------

Notice that in the jump from step 4 to step 5, shown in the section above, we had the "37!" terms cancel out. What this means is that the prime number 37 is nowhere to be found anywhere in the factorization of 1,101,716,330

Why is this important? Because it tells us that the fraction [tex]\frac{37}{1,101,716,330}\\\\[/tex] cannot be reduced.

Side note: That fraction converts to the decimal form 0.00000003358397 approximately and that converts to the percentage form 0.000003358397%; both of which are very very small numbers. We can see that the odds are definitely stacked against the player.
