Answer:

49*

Step-by-step explanation:

There are 180 degrees in a triangle

90*+41*=131*

180*-131*=49*

Answer:

49

Step-by-step explanation:

You find the x value by first knowing that all angles in a triangle would equal 180. With that information, you add all the sides given to you which would equal 131 then subtract that from 180 to find the missing angle. Which is 49 degrees.

Answer:

foot = 5 ft

luff = 20 ft

Step-by-step explanation:

In the picture attached, the diagram of the sail is shown. A right triangle is formed, where 50 ft² is its area, which can be computed as follows:

foot*luff*1/2 = 50

We also know that luff = 4*foot. Replacing into the previous equation:

foot*(foot*4)*1/2 = 50

foot²*2 = 50

foot² = 50/2

foot = √25

foot = 5 ft

luff = 4*5 = 20 ft

Answer:

Step-by-step explanation:

The graph for the inequality is attached with the answer.

We have a linear inequality -

y < 3x + 1

We have to plot the graph of this linear inequality.

An inequality in mathematics compares two values or expressions, showing if one is less than, greater than, or simply not equal to another value.

According to the question, we have -

y < 3x + 1

Now, in order to plot the graph for this inequality, let -

y = 3x + 1

Plot the line for the above equation. Remember to plot the graph in the form of dashed line since the inequality is strict inequality.

Consider the point (0, 0) -

Solve the inequality for the point (0, 0), we get -

0 < 3 x 0 + 1

0 < 1

Which is true.

Hence, shade the complete area on that side of line where the point

(0, 0) lies.

Answer:

Step-by-step explanation:

100/100 = 100 ÷ 100 = 100% = 1. Multiply a number by the fraction 100/100

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

The company payment is $1440.

Carol's total cost is $610.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Cost of the bill = $2,050

Company payment = 80% of the bill less the deductible

This means,

80/100 x 2,050 = 1640

Company payment.

= 1640 - 200

= $1440

Now,

Carol's total cost.

= 2,050 - 1440

= $610

Thus,

The company payment is $1440.

Carol's total cost is $610.

Answer:

Step-by-step explanation:

Each new term is the sum of the two preceding terms.  Given 2, 9, etc., we see that a number between 2 and 9 is missing; call it x.  Then 2 + x must equal 9, and so x = 7, and so the first three terms are 2, 7, 9.  Repeating the process, we add 7 and 9, obtaining 16; thus the first four terms are 2, 7, 9, 16.  Continuing this pattern, we add 9 and 16 to obtain the fifth term, which is 25:  2, 7, 9, 16, 25.  And so on.

Answer:

Step-by-step explanation:

1). f(z) = [tex]\sqrt{z-5}[/tex]

   The given function 'f' is defined for (z - 5) ≥ 0

    z ≥ 5

   Therefore, domain of the function will be [5, ∞)

   Or "All real numbers greater than or equal to 5"

2). [tex]f(z)=\frac{1}{z-8}[/tex]

    Domain: "All real numbers except 8."

    Since the given function is not defined for z = 8

3). f(z) = [tex]\sqrt{z}[/tex]

    The given function is defined for every real numbers greater and equal to zero.

    Domain: "All positive real numbers and 0"

4). f(x) = 8x

    This function is defined for all real numbers.

    "Domain: All real numbers"

Answer:

(x, y) = (-404/55, 83/11)

Step-by-step explanation:

15x + 4y = -80

5x + 5y = 1

Multiplying both side of 2nd equation by 3:

=>

15x + 4y = -80

15x + 15y = 3

Subtracting the 1st equation from 2nd equation:

=>

11y =  83

Dividing both sides by 11 to work out y:

=> y = 83/11

Substituting y back into 2nd equation to work out x:

=> 5x + 5(83/11) = 1

=> 5x + 415/11 = 1

=> 5x = 1 - 415/11

=> 5x = -404/11

=> x = (-404/11)/5

=> x = -404/55

=> (x, y) = (-404/55, 83/11)

Hope this helps!

Answer:

y = (1/2)(x) + 1/2

Step-by-step explanation:

The x-intercept is (-1, 0) and the y-intercept appears to be (0, 1/2).

As we go from the x-intercept to the y-intercept, x increases by 1 and y increases by 1/2.  Thus, the slope of the line is m = rise / run = 1/2.

Knowing that m = 1/2 and b = (0, 1/2), we can write the equation of this line in slope-intercept form as

y = (1/2)(x) + 1/2

(4)Profit Function: P(x,y)=2x+3y

(5)Maximum profit =$467

Step-by-step explanation:

Let the number of sneakers in stock =x

Let the number of sandals in stock =y

(1)The owner of the store estimates that she won't sell more than 200 shoes each month. Therefore, an inequality that represents the possible amount of shoes she can purchase each month is:

[tex]x+y\leq 200[/tex]

[tex]x>0, y> 0[/tex]

(2)She does not plan to invest more than $2,000 on the inventory of the shoes.

The store owner pays $8 for the sneakers and $14 for the sandals.

Therefore, an inequality that represents how many sneakers and sandals she has in stock each month is:

[tex]8x+14y\leq 2000[/tex]

(3)From the graph, the coordinates of the four vertices are:

(4)The sneakers can be sold for $10 and the sandals can be sold for $17.

Profit on one sneaker =$10-8=$2

Profit on one sandal =$17-14=$3

Profit Function: P(x,y)=2x+3y

(5)

At (0,143), Profit =2x+3y=2(0)+3(143)=$429

At (0,0), Profit =2x+3y=2(0)+3(0)=$0

At (133, 67), Profit =2x+3y=2(133)+3(67)=$467

At (200,0), , Profit =2x+3y=2(200)+3(0)=$400

Her maximum profit will be $467 when she sells 133 sneakers and 67 sandals.

Answer:A=6 B=-4.5

Step-by-step explanation:

We want to find the values of A and B such that the given system of equations has no solutions. We will find that the values of A and B can be:

B = -4.5

A = 6

A system of linear equations has no solutions when the lines are parallel (so the lines never do intercept).

Here the system is:

3x + 4y = A

Bx – 6y = 15

Remember that two lines are parallel if and only if they have the same slope and different y-intercept, then let's write both equations in the slope-intercept form:

y = A/4 - (3/4)*x

y = -15/6 + (B/6)*x

So we must have:

B/6 = -3/4

A/4 ≠ -15/6

From the first one we get:

B = (-3/4)*6 = -4.5

From the second one we get:

A  ≠ (-15/6)*4 = -10

Then from the given pairs, the only one that causes the system to have no solutions is:

B = -4.5

A = 6
