Answer: The cost of 1 liter milk is $ 0.75  and the cost of a loaf of bread is $1.75

Step-by-step explanation:

Let the cost of one liter of milk  is m dollar and the cost of one loaf of bread is b dollar.

Since, the total cost of the 3 liter milk and 5 loaf of bread = $ 11

That is, 3 m + 5 b = 11   ----------(1)

And, the cost of the 4 liter of milk and 4 loaf of bread = $ 10

That is, 4 m + 4 b = 10 -----------(2)

4 × Equation (1),

12 m + 20 b = 44 -----------(3)

3 × Equation (2),

12 m + 12 b = 30 --------------(4)

Equation (3) - Equation (4),

We get, 8 b = 14

⇒ b = 14/8 = 1.75

 By putting the value of b in equation (1)

We get,

3 m = 11 - 1.75×5 ⇒ m = 2.25/3 = 0.75

Thus, the price of one liter of milk = $ 0.75

And, the price of one loaf = $ 1.75

Answer:

The cost of 1 liter milk is $ 0.75  and the cost of a loaf of bread is $1.75

P (odd number or number greater than 4) =  4/6  = 2/3

Answer:

F(x) = x+7

g(x) = 1/(x-13)

fog(x) = [1/(x-13)] + 7

The denominator of the fraction cannot be equal to zero.

So, the domain of fog(x) is x∈R~{13}

Step-by-step explanation:

To find the domain of (f•g)(x), substitute g(x) into f(x) and identify any values of x that make the expression undefined.

The function (f•g)(x) represents the composition of two functions, f(x) and g(x). To find the domain of (f•g)(x), we need to determine the values of x for which the composition is defined.

The composition (f•g)(x) can be written as f(g(x)). Substituting g(x)=1/x-13 into f(x)=x+7, we have f(g(x))=(1/x-13)+7.

The domain of (f•g)(x) consists of all the values of x for which the expression (1/x-13)+7 is defined. Since division by zero is not defined, we need to exclude x=0 from the domain. Additionally, we need to exclude the value x=13 because the expression (1/x-13)+7 would lead to division by zero. Therefore, the domain of (f•g)(x) is x≠0, 13.

Answer:

A y = -x+2

Step-by-step explanation:

To find the slope of the line m we use the formula

slope = (y2-y1)/(x2-x1)

         = (-9--7)/(4-2)

         = (-9+7)/(4-2)

        = -2/2

        = -1

When lines are parallel, the slopes are the same.  We need to find a line with slope of -1

y = -1x+2 is written in the form y =mx+b where m is the slope

m=-1  so the slope is -1

This line has the same slope so it is parallel to the line above.

Answer:

male comedy: 31 male drama: 9

female comedy: 36 female drama: 24

Step-by-step explanation:

add f+m=100 total

31 males for comedy

40 males - 31 males = 9 males for drama

55% chose comedy so 55-31 males = 24 females for comedy

60 total females - 24 for comedy = 36 females for drama

Answer:

                         Dramas              Comedies

Males                   9                             31

Females             36                            24

Step-by-step explanation:

It is given that Lamar surveyed 40 males and 60 females about whether they prefer dramas or comedies.

Total males = 40

Total females = 60

Total people surveyed = 40 + 60 = 100

It is given that 55% of surveyed people preferred comedies.

People preferred comedies = [tex]100\times \frac{55}{100}=55[/tex]

It is given that males who preferred comedies = 31

Males who preferred drama is the difference of number of males and males who preferred comedies.

Males, drama = 40 - 31 = 9

Females who preferred comedies is the difference of people who preferred comedies and males who preferred comedies.

Females, comedies = 55 - 31 = 24

Females who preferred drama is the difference of number of females and females who preferred comedies.

Females, drama = 60 - 24 = 36

Therefore the table can be filled as

                         Dramas              Comedies

Males                   9                             31

Females             36                            24

Answer:

r=8

Step-by-step explanation:

The formula for slope is

m = (y2-y1)/ (x2-x1)

Substitute in what we know.

8/3 = (-7-1)/(5-r)

Simplify

8/3 = -8/(5-r)

We can use cross products to help us solve.

8 * (5-r) = 3 * (-8)

divide each side by 8

8/8 * (5-r) = 3 * (-8)/8

5-r = -3

Subtract 5 from each side

5-r-5 = -3-5

-r = -8

Multiply by -1

r = 8

Rewrite [tex]x\geq-3y-6[/tex] as a [tex]y\geq -\frac{1}{3}x-2[/tex]. Then mark each set with different color and take the intersection of these.

Answer:

Neither

Step-by-step explanation:

y = 5/3 x + 3, this line has slope = 5/3

20x + 12y = 12

12y = -20x + 12

y = -20/12 x + 1

y = - 5/3 x + 1, this line has slope = - 5/3

Parralel ; same slopes

Perpendicular; slopes are opposite and reciprocal

So answer is neither pair parallel nor perpendicular

The pair of equations y = 5/3x + 3 and 20x + 12y = 12 are parallel because they both have the same slope of 5/3 once the second equation is put into slope-intercept form.

To determine if the pair of equations y = 5/3x + 3 and 20x + 12y = 12 are parallel, perpendicular, or neither, we must first put both equations into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept. The equation y = 5/3x + 3 is already in slope-intercept form with a slope of 5/3. To convert the second equation into slope-intercept form, we can rewrite it as 12y = -20x + 12, and then y = (-20/12)x + 1, which simplifies to y = -5/3x + 1.

Now, comparing the slopes of these two lines, we see that both slopes are equal, meaning the lines are parallel to each other since they have the same slope but different y-intercepts.

Answer: His smallest age could be 16 years.

Step-by-step explanation:

Since we have given that

Four-fifths of his current age is greater than three-quarters of his age one year from now.

Let his present age be x

So, According to question,

[tex]\frac{4}{5}x>\frac{3}{4}(x+1)[/tex]

Take the equality,

[tex]\frac{4}{5}x=\frac{3}{4}(x+1)\\\\\frac{4}{5}x=\frac{3}{4}x+\frac{3}{4}\\\\\frac{4}{5}x-\frac{3}{4}x=\frac{3}{4}\\\\\frac{16x-15x}{20}=\frac{3}{4}\\\\\frac{x}{20}=\frac{3}{4}\\\\x=\frac{3\times 20}{4}\\\\x=15[/tex]

So, [tex]x>15[/tex]

m = 1575

Step-by-step explanation:

so first you have to simplify the equation: m = 45 (35) because the absolute value of -35 is 35. after that you multiply 45 by 35 and end up with 1575. I am assuming that the 45 is supposed to be multiplied by the absolute value.

Answer:

Option D.

Step-by-step explanation:

Consider the given function

[tex]f(x)=0.25^x+5[/tex]

We need to find the graph of given function.

Substitute x=0 in the given function to find the y-intercept of the function.

[tex]f(0)=0.25^(0)+5[/tex]

[tex]f(0)=1+5[/tex]

[tex]f(0)=6[/tex]

So, y-intercept of the function is 6.

[tex](0.25)^x\rightarrow \infty[/tex] as [tex]x\rightarrow -\infty[/tex]

[tex](0.25)^x\rightarrow 0[/tex] as [tex]x\rightarrow \infty[/tex]

We can concluded that

[tex]f(x)\rightarrow \infty[/tex] as [tex]x\rightarrow -\infty[/tex]

[tex]f(x)\rightarrow 5[/tex] as [tex]x\rightarrow \infty[/tex]

Therefore, the correct option is D.

Answer:

k = 60

Step-by-step explanation:

2k + 11 is a same side corresponding angle, hence

2k + 11 = 131 ( vertically opposite angles )

subtract 11 from both sides

2k = 120 ( divide both sides by 2 )

k = 60

Answer:

Option C. k = 60

Step-by-step explanation:

There are two lines Z and Y and crossed by a transverse x.

We have to find the value of k.

Since opposite angle of ( 2k + 11 ) is corresponding angle of 131°

so opposite angle of ( 2k + 11 ) will be = (2k + 11)

and corresponding angles are equal in measure.

So 2k + 11 = 131

    2k = 131 - 11

   2k = 120

    k = 60

Option C k = 60 is the answer.

Answer:

16 pounds

Step-by-step explanation:

The ratio of no. of packages of red pepper to no. of packages of green pepper is given 8 is to 13.

So, atleast 8 packages of red pepper are sold

Therefore, least possible weight of red peppers in the bin = 2×8 = 16 pounds.

The least possible weight of red peppers in a supermarket bin with a ratio of 8 to 13 of red to green peppers, where each package weighs 2 pounds, is 16 pounds.

To find the least possible weight, we assume the smallest number of packages that maintain the ratio. Multiplying both numbers of the ratio by 2 pounds gives us the weight of the red and green peppers, but since we want the least possible weight of red peppers, we'll only calculate for red.

Therefore, if we have 8 packages of red peppers, each weighing 2 pounds, the calculation would be:
