Answer:
See below
Step-by-step explanation:
The probability of choosing a red card is 1/2. Half of the cards are hearts/diamonds and half of the cards are clubs/spades.
The probability of choosing the queen of hearts is 1/52. There is one queen of hearts in a 52 card deck.
The probability of choosing a club is 1/4. 1/4 of the cards are clubs, 1/4 are spades, 1/4 are diamonds, 1/4 are hearts.
The probability of choosing a 5, 6, or 7 is 3/13. There is a 5, 6, 7 in all 4 sets, clubs, spades, hearts, and diamonds. So there are 12 total cards that either read 5, 6, or 7 out of the 52 total cards. 12/52 simplifies to 3/13.

Answer:
27/4 or 6 3/4
Step-by-step explanation:
Change all mixed numbers into improper fractions
2 1/9 = 19/9
6 1/4 = 25/4
19/9 ÷ 2/3 - 25/4 x 2/5
dividing fractions you can multiply and use reciprocal of the fraction (means you switch the top and bottom numbers)
19/9 x 3/2 - 25/4 x 2/5
you can reduce the top and bottom numbers to make them smaller by dividing. find a common number to divide them by, you can cross out the numbers and just put the new equation below
19/3 x 1/2 - 5/4 x 2/1
multiply across the fractions first PEMDAS, then subtract
19/6 - 10/4 (multiply by 2 and 3 respectively to get both bottom numbers the same, multiply by the same number on top)
57/12 - 30/12 = 27/12
1/5 x 1/3 + 2/5 x 2/3
1/15 + 4/15 = 5/15 or 1/3
27/12 / 1/3
you can multiply the fractions and flip the top and bottom numbers of 1/3
27/12 x 3/1
reduce 12 and 3
27/4 x 1/1 = 27/4 or 6 3/4
Write the side length of the square as a square root. Is the side length a rational number? Explain. a= 121
Answer:
yes
Step-by-step explanation:
Note that [tex]121=11^2[/tex].
The side length of the square with an area of [tex]121=11^2[/tex] will be [tex]\sqrt{11^2}[/tex].
Recall that [tex]\sqrt{a^2}=a[/tex], so the side length is [tex]\sqrt{11^2}=11[/tex]. [tex]11[/tex] is clearly rational because it's an integer, so the answer is [tex]\boxed{yes}[/tex], it is rational.

x = 25
Step-by-step explanation:
Internal angles of a triangle = 180 degrees
So knowing this we can form the following equation
(x + 26) + (x + 14) + (4x - 10) = 180
Simplify
(x + x + 4x) + (26 + 14 - 10) = 180
6x + 30 = 180
Rearrange for x
6x = 180 - 30
6x = 150
x = 25

bChoose the equation that represents the graph.
Oy = x - 3
Oy = -x + 3
Oy = -x-3
Oy = x + 3
The graph illustrates a linear function, because the graph is a straight line
The equation of the graph is (d) y = x +3
The points on the line are:
[tex](x_1,y_1) = (-3,0)[/tex]
[tex](x_2,y_2) = (0,3)[/tex]
First, we calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substitute values for x1, x2, y1 and y2
[tex]m = \frac{3-0}{0--3}[/tex]
Simplify
[tex]m = \frac{3}{3}[/tex]
Divide
[tex]m = 1[/tex]
The equation of the line is then calculated using the following formula:
[tex]y = m(x - x_1) + y_1[/tex]
Substitute values for m, x1 and y1
[tex]y = 1(x - -3) + 0[/tex]
Simplify
[tex]y = 1(x +3)[/tex]
Open bracket
[tex]y = x +3[/tex]
Hence, the equation of the graph is (d) y = x +3

Line segment JK has endpoints J(2,-3) and K(-4,6). what are the coordinates of the midpoint of JK
Answer:
The midpoint is (-1, 1.5)
Step-by-step explanation:
To find the x coordinate of the midpoint, average the x coordinates of the endpoints
(2+-4)/2 = -2/2 = -1
To find the y coordinate of the midpoint, average the y coordinates of the endpoints
(-3+6)/2 = 3/2 = 1.5
The midpoint is (-1, 1.5)

Answer:
The 6 pack
Step-by-step explanation:
i searched it up
The required option that has a lesser price per mini football is a package of 8.
Given that,
at a toy store, Colton can buy a package of 6 mini footballs for $7.50. or a package of 8 mini footballs for $9.60. wich option has the lesser price per mini football is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
For 6 package footballs the cost of a mini football = 7.50 / 6 = $1.25.
For 8 package footballs the cost of a mini football = 9.60 / 8 = $1.20.
Thus, the required option that has a lesser price per mini football is a package of 8.

Answer:
B
Step-by-step explanation:
Line L and m are prendicular with point of intersection P. Noah says that a 180 degree rotation with center p has the same effects on points in the plane as reflecting over line m. Do you agree with Noah? Explain your reasoning
The point of intersection is the point where two or more lines meet.
Noah's claim is incorrect
The given parameters are:
Line l, line m and point of intersection p
See attachment for illustration of the perpendicular lines l and m.
Figure 1 represents the original lineFigure 2 represents the line rotated 180 degreesFigure 3 represents the line reflected over line mUsing the attachment as a guide, we can see that both transformations do not have the same effect on the points on both lines.
This is so because, figures 2 and 3 can be transformed to one another by reflecting across line l.
Hence, Noah's claim is incorrect

What is the solution to the equation −p − 13 = −4 /3 p + 2/3 ( 5p − 6 ) ?
((will give brainliest to best answer
Answer:
The answer is p= 2 and 1/3
Step-by-step explanation:
This answer can be found using the order of operations to solve for p.
Start by distributing 2/3 by (5p-6)
add -4/3p to 10/3p equaling 6/3p or 2p
subtract 13 from both sides
-p= 2p - 7
p=2 and 1/3

Answer:
y = -1/5x - 10
Step-by-step explanation:
Pick any two points on the line.
(0,-10) and (50,-20)
find the slope by using m = y2-y1/x2 - x1(rise over run)
m = -20-(-10) / 50 - 0
m = -10/50 = -1/5 -- this is your slope
slope intercept form is y = mx + b, but we need to find your b, which is your y intercept. you find this by asking yourself, what is the y coordinate when x = 0? It is -10.
so now you have all the points you need.
y = mx + b
y = -1/5x - 10

Determine if (0,-5) is a
solution to the equation
y = -5x
Plug (0,-5) into the equation -
-5 = -5(0)
-5 times 0 is 0
-5 = 0
(0,-5) is NOT a solution to the equation.
Good luck!
Answer:
No, it is not the solution to the equation.
Step-by-step explanation:
(0, -5)
y = -5x
So we have to plug in the values for x and y. 0 is our x value and -5 is our y value.
-5 = -5(0)
-5 = 0
Therefore, (0, -5) is not a solution to the equation
