[tex]\frac{8}{52}[/tex] = 0.15384615384 = 15.38%

Step-by-step explanation:

There are 4 7 cards and 4 queen cards so,

[tex]\frac{4}{52}[/tex] + [tex]\frac{4}{52}[/tex] = [tex]\frac{8}{52}[/tex]

Answer:

2 x ( -4 ) = -8

Step-by-step explanation:

2 x 4 = 8

a negative x a positive = negative

so therefore the answer is -8

Answer:

The equation of the line is;

3y = 2x-8

Step-by-step explanation:

Firstly, we need the to get the slope of the given line

To do this, we will write the equation of the line in the standard form

the standard form

is;

y = mx + b

where m is the slope and b is the y-intercept

y -4 = 2/3(x-3)

y -4 = 2x/3 - 2

y = 2x/3 -2 + 4

y = 2x/3 + 2

with respect to the given equation, the slope of the line is 2/3

Mathematically, when two lines are parallel, the slopes of the line are equal

So now, we want to find the equation of the line that has a slope of 2/3 and passes through the point (1,-2)

so;

y = 2x/3 + b

So substitute the values of (1,-2)

1 for x and -2 for y

-2 = 2/3(1) + b

-2 = 2/3 + b

b = -2 - 2/3

b = (-6-2)/3 = -8/3

So the equation of that line is;

y = 2/3x - 8/3

Multiply through by 3

3y = 2x - 8

They are the same

Answer:

3 < x < 17

Step-by-step explanation:

Given 2 sides of a triangle then the third side x is in the range

difference of 2 sides < x < sum of 2 sides , that is

10 - 7 < x < 10 + 7

3 < x < 17

Answer:

We know that:

She makes $19 per hour of lifeguarding.

She makes $8 per hour walking dogs.

She can work at most 7 hours per week.

She must earn a minimum of $80 per week.

If x represents the number of hours lifeguarding and y represents the number of hours walking dogs, the inequalities will be:

x + y ≥ 7 hours.

(this says that she can work at most 7 hours per week)

x*$19 + y*$8 ≥ $80

(this says that she can earn a minimum of $80)

Then the system of inequalities is:

x + y ≥ 7 hours.

x*$19 + y*$8 ≥ $80

To graph these two we can write them as lines in standard form and simply graph both inequalities, the solution of the system will be the intersection between the solutions of each inequality.

Here we also should add the inequalities:

x ≥ 0

y ≥ 0

So we only look at the first quadrant.

The graph can be seen in the image below: (the dark blue is the solution region for the first inequality, the light blue one is the solution region for the second inequality)

One possible solution can be:

x = 4 and y = 1

or

x = 4 and y = 2

and there are a lot of other possible solutions.

Answer:

73

Step-by-step explanation:

180-(39+68)

180-(107)

=73

M=73

Answer: 73 degree

Step-by-step explanation:

Every triangle the measurment

of the whole trinagle is 180 degree. So 180-39-68=73

So the measurment  for angle M is 73 degree.

Answer:

Solve for X; whereas lb=pound, $=cost

1lb = $12.55

0.6lb = $X; therefore 6/10 lb = $X

Rewrite:

$12.55/1 lb = $X/6/10 lb; therefore $12.55/1 lb = 10/6(X); 10X=$12.55(6); 10X=$75.30; X=$75.30/10

X=$7.53 for .6 lbs.

Answer:

y = -3/11x + 4/11

Step-by-step explanation:

y2 - y1/ x2 - x1

-1 - 2/ 5 - (-6)

-3 / 11

y = -3/11x + b

-1 = -3/11(5) + b

-1 = -15/11 + b

4/11 = b

It looks like a "V" going straight up from 0, and hits both 4 and -4 y while going up perfectly

The graph opens upward, and it has a vertex of (0,0)

The vertex of an equation is the minimum or the maximum point on the graph of the equation

The equation of the graph is given as:

[tex]f(x) = 4|x|[/tex]

The above equation represents an absolute value function

An absolute value function is represented as:

[tex]f(x) = a|x -h| + k[/tex]

So, by comparison, we have:

[tex]a = 4[/tex]

[tex]h = 0[/tex]

[tex]k = 0[/tex]

This means that the graph opens upward, and it has a vertex of (0,0)

See attachment for the graph of [tex]f(x) = 4|x|[/tex]

Answer:

$11.33

Step-by-step explanation:

First I did 8.80 x 0.25 and I got 11. Than I did 11.00 x 0.03 and I got $11.33. The total cost was $11.33

The total cost of the rake is $11.33.

Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.

Given that, a rake was marked up 25% from an original cost of $8.80.

25% of the original cost of $8.80 is

0.25×8.80 =$2.2

So the marked up price was 8.80+2.20

= $11

He then paid an additional 3% in sales tax, that is

11 + 0.03×11 = $11.33

Therefore, the total cost of the rake is $11.33.

Answer: 80ft squared

Step-by-step explanation: 18 * 4 + 8 = 80

Responder:

462 assentos

Explicação passo a passo:

Dado que :

Número da linha = 12; Número de assentos por fila = 16

Número de linhas = 15; número de assentos por fila = 18

Número total de assentos para as 12 filas:

12 * 16 = 192 assentos

Número total de assentos para as 18 filas:

15 * 18 = 270 assentos

Número total de assentos:

(192 + 270) = 462 assentos

Answer:

slope = 4

y intercept = -3

Step-by-step explanation:

The equation is put in slope intercept form

Slope intercept form: y = mx + b

where m = slope and b = y intercept

looking at slope intercept form

4 is located where m should be , meaning that the slope is equal to 4 and

-3 is located where b should be , meaning that the y intercept is -3

Therefore the answers are the first and last option choices.

Answer:

y = 0.5

x = 4 - y (0.5)

Answer:

P (2 and then odd number) = [tex]\frac{1}{12}[/tex]

Step-by-step explanation:

Probability refers to chances of occurrence of any event.

A number cube is rolled twice.

Possible outcomes are as follows:

[tex](1,1),(1,2),(1,3),(1,4),(1,5),(1,6)[/tex]

[tex](2,1),(2,2),(2,3),(2,4),(2,5),(2,6)[/tex]

[tex](3,1),(3,2),(3,3),(3,4),(3,5),(3,6)[/tex]

[tex](4,1),(4,2),(4,3),(4,4),(4,5),(4,6)[/tex]

[tex](5,1),(5,2),(5,3),(5,4),(5,5),(5,6)[/tex]

[tex](6,1),(6,2),(6,3),(6,4),(6,5),(6,6)[/tex]

Total number of outcomes = 36

Favorable outcomes include outcomes with 2 and then odd number.

So,

Favorable outcomes are [tex](2,1),(2,3),(2,5)[/tex]

Number of favorable outcomes = 3

Probability is equal to number of favorable outcomes divided by total number of outcomes.

Therefore,

P (2 and then odd number) = Number of favorable outcomes ÷ Total number of outcomes

[tex]=\frac{3}{36}[/tex]

[tex]=\frac{1}{12}[/tex]
