Answer:

C. These lines are perpendicular

Step-by-step explanation:

Answer:

C. the lines are perpendicular

Step-by-step explanation:

you can tell right away they're perpendicular because the slope gets flipped and changed the sign for in the second equation

2/3 going to -3/2 or vice versa means they are perpendicular

if they had the same slope they would have been parallel

SIMPLFIED FRACTION: Convert to a mixed number by placing the numbers to the right of the decimal over 10.Reduce the fraction. Then, convert the mixed number to an improper fraction by multiplying the denominator by the whole number and adding the numerator to get the new numerator. Place this new numerator over the original denominator.

Answer: A 4/52        B X=260    C i dont know sorry

   D Yes, it did because the coordinates of the other polygons would be a direct opposite of polygon ABCD depending on what line it reflects off of. If it reflects off of the y-axis then they would be the same coordinates, just that the X values of the coordinates would now be positive, for the reflection of the x-axis it is also the same except that now the x value would now stay negative while the y values would now be positive. For y=x, it is different because now the X, and Y place values now switch (for example, (-3,-2) would now be (-2,-3)). For y=-x, the place values would both switch, and now be positive.          

E  The number of times a face card is expected to be drawn in 260 draws is 60 times.

F A 4/52 B X=260 D Yes, it did because the coordinates of the other polygons would be a direct opposite of polygon ABCD depending on what line it reflects off of. If it reflects off of the y-axis then they would be the same coordinates, just that the X values of the coordinates would now be positive, for the reflection of the x-axis it is also the same except that now the x value would now stay negative while the y values would now be positive. For y=x, it is different because now the X, and Y place values now switch (for example, (-3,-2) would now be (-2,-3)). For y=-x, the place values would both switch, and now be positive. E  The number of times a face card is expected to be drawn in 260 draws is 60 times. F 25 % Explanation: Assuming a random drawing from a standard pack of 52 cards: 1 4 = 25 % of the cards are hearts (i.e. 13 out of 52 ) G 25 % Explanation: Assuming a random drawing from a standard pack of 52 cards: 1 4 = 25 % of the cards are hearts (i.e. 13 out of 52 )    

G   How many face cards are there in a standard pack of 52 cards?

The deck has four suits: spades, clubs,hearts, and diamonds. Each suit has 3 face cards: king, queen and jack. So altogether there are 4 × 3 = 12 face cards in the 52-card deck.

There are different opinions about whether the ace is a picture card. Aces are not included in the answer.

The size of the sample space is 52. Assuming the cards are well-shuffled,

Pr(getting a face card when one card is drawn) = 1252=626=313

explanation : this took me forever

Part A:

The ratio of threes to the total number of cards in the deck is 1 : 13.

Part B:

1/13 = x/260

Part C:

The number of times you should expect a three to be drawn out of a total of 260 draws is 20.

Part D:

It is an estimate because the actual number of times a three is drawn in 260 draws may vary due to chance.

Part E:

We should expect a face card to be drawn approximately 60 times out of 260 draws.

Part F:

We should expect a heart to be drawn approximately 65 times out of 260 draws.

Part G:

We should not be surprised if a face card is drawn more times than a heart in 260 random draws.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Part A:

There are four threes in the deck and a total of 52 cards.

Therefore, the ratio of threes to the total number of cards in the deck is:

= Threes : Total number of cards

= 4 : 52

Simplifying the ratio by dividing both sides by 4 gives:

= Threes : Total number of cards

= 1 : 13

Part B:

Let x represent the number of times a three is expected to be drawn out of a total of 260 draws.

Using the ratio from part A, we can write the following proportion:

1/13 = x/260

Part C:

Solving the proportion from part B for x gives:

x = (1/13) x 260

x = 20

Therefore, we should expect a three to be drawn approximately 20 times out of 260 draws.

Part D:

The answer in part C is an estimate because the actual number of times a three is drawn in 260 draws may vary due to chance.

Part E:

There are 12 face cards in the deck (4 jacks, 4 queens, and 4 kings).

Using the ratio from part A, we can set up the following proportion:

4 x 12 / 52 = x / 260

Solving for x gives:

x = 60

Therefore, we should expect a face card to be drawn approximately 60 times out of 260 draws.

Part F:b

There are 13 hearts in the deck.

Using the ratio from part A, we can set up the following proportion:

13/52 = x/260

Solving for x gives:

x = 65

Therefore, we should expect a heart to be drawn approximately 65 times out of 260 draws.

Part G:

We should not be surprised if a face card is drawn more times than a heart in 260 random draws.

This is because there are more face cards in the deck (12) than hearts (13), and the proportion of face cards to the total number of cards is greater than the proportion of hearts to the total number of cards.

Thus,

All parts of the answer are mentioned above.

Step-by-step explanation:

The given equations are :

y=-x+2  ....(1)

y = -4x +7 ....(2)

From equation (1) and (2)

-x+2 = -4x +7

Taking like terms together

-x+4x=7-2

3x = 5

x = 1.667

Put the value of x in equation (1)

y=-(1.667)+2

y = 0.333

The solution of the equations are (1.667,0.333). The attached figure shows the graph for the equations.

The measure of the exterior angle x° is equal to 132° considering the exterior angle x° has 86° and 46° as its interior opposite angles of a triangle.

The exterior angle of a triangle is equal to the sum of the two opposite interior angles.

To calculate for the exterior angle x°, we shall ad the two interior opposite angles of the triangle to derive their value, and thus equate to the unknown exterior angle x°.

interior opposite angles are 86° and 46°

sum of interior opposite angles = 86° + 46°

sum of interior opposite angles = 132°

so;

x° = 132°

In conclusion, the exterior angle x = 132° for the triangle whose two interior opposite angles to x are 86° and 46°.

Answer:

False

Step-by-step explanation:

Answer:

B is right

Step-by-step explanation:

To add the fractions you need common denominators (the number at the bottom of the fraction) so the 12 is the common denominator. since the denominator on the bottom which is 4 turns into 12, you divide those and get 3. Once you get 3 you multiply it by the top number of 4 which is 9. Same with the next fraction which equals 10/12. Lastly, you add the top numbers together only since the bottom is already simplified. And.. 19/12 equals 1 7/12 because theres is 12/12 in 19/12 and leaves 7 extra which is 1 7/12

Answer:

3/4=9/12.      5/6 10/12

Step-by-step explanation:

ok this is easy so when it puts you 3/4 = /12 and 5/6 = /12

all you have to do is

multiply 4 times 3 for the bottom to get 12 and multiply 3 on top to

so 3/4 = 9/12

and for 5/6 = /12 you have to multiply 6 times 2 to get 12 so you multiply 2 on top as well so 5/6 = 10/12

8 - 7x = 4y

4y = 8 - 7x

y = (8 - 7x)/4

= 2 - 7/4x

y = -7/4x + 2

Slope = m = -7/4

Answer:

slope = - [tex]\frac{7}{4}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

8 - 7x = 4y, that is

4y = - 7x + 8 ( divide all terms by 4 )

y = - [tex]\frac{7}{4}[/tex] x + 2 ← in slope- intercept form

with slope m = - [tex]\frac{7}{4}[/tex]
