The value of x in the isosceles triangle is 9.25.

An isosceles triangle is a polygon that has three sides. The opposite length have the same length and equal angles.  has two opposite sides. If the two angles are equal , it means the triangle is an isosceles.

Th perimeter of an isosceles triangle is the sum of the length of the three sides of the triangle.

Perimeter = (2 x length of leg) + base

43 = (2x x) + 2x - 6

43 = 2x + 2x - 6

Answer:15

Step-by-step explanation:

The mean is the sum of all the numbers divided by the amount of numbers

Step 1: Add

5+25+10+15+20 = 75

Step 2: Divide

Since there are 5 numbers divide 75 by 5

75/5 = 15

The answer is 15

Answer: The mean is 15

Step-by-step explanation:

   To find the mean, we add all the numbers together and divide by the number of numbers.

[tex]\displaystyle \frac{5+ 25+10+ 15+ 20}{5} = \frac{75}{5} = 15[/tex]

The rate  that is the best deal for a bottle of mustard is: C: $2.42 for 12 oz.

a. $1.26 for 6 oz

Unit rate = $1.26 / 6 oz

Step-by-step explanation:

If the domain of the function f(x) = 2x + 1 is {-2 ≤ x ≤ 3}, an integer which is not in the range is: a) -4.

In Mathematics, a range can be defined as the set of all real numbers that connects with the elements of a domain. This ultimately implies that, a range refers to the set of all possible output numerical values (real numbers), which are shown on the y-axis of a graph.

When x = -2, the range of this function f(x) = 2x + 1 is given by:

f(-2) = 2(-2) + 1

f(-2) = -4 + 1

f(-2) = -3

When x = 3, the range of this function f(x) = 2x + 1 is given by:

f(3) = 2(3) + 1

f(3) = 6 + 1

f(3) = 7

Therefore, the range of this function is -3 ≤ y ≤ 7 and as such, -4 is an integer that is not within the range as shown in the number line attached below.

Step-by-step explanation:

OB = 10 cm

OA = OC = Radius = 4 cm

COS <AB = OA/OB = 4/10 = 2/5 =

COS< COB = OC/OB = 4/10 = 2/5

=> <AOC = <AOB + <COB

=> <AOC = Cos-¹(2/5) + Cos-¹(2/5)

=> <AOC = 2 Cos-¹(2/5)

=> <AOC = 2 * 66.42

=> <AOC = 132.84°

if D is in minor arc then length of arc ADC. = ( 132.84°/360°) 2π = 9.274 cm

if D is in major arc then length of arc ADC. = ((360° -132.84°)/360°) 2π = 15.859 cm

The percent of chloride ion in a sample if 2. 500 g of the sample produces 1. 750 g of AgCl when treated with excess ag⁺  is 17.2%

The percent of chloride can be calculate as follow:

Mass of AgCl precipitated = 1.750 g

Molar mass of AgCl = 143.32 g/mol

Molar mass of Chlorine atom = 35.45 g/mol

Asume, all the chlorine in the sample is precipitated to silver chloride. So, the mass of chlorine in silver chloride will be equal to the mass of chlorine present in the sample.

To calculate the mass of chlorine in given mass of AgCl, we apply unitary method:

In 143.32 g of silver chloride, mass of chlorine present is 35.45 g

So, in 1.3487 g of silver chloride, mass of chlorine present will be =

35.45g/143.32 g * 1.750 g = 0.43 g

To calculate the percentage composition of chlorine in pure chloride compound, as follows:

Mass of pure chloride compound = 2.500 g

Mass of chlorine = 0.43 g

% Chlorine = 0.43/2.5 *100

% Chlorine = 17.2 %

Therefore, the mass percentage of chloride in pure chloride compound is 17.2%

The expression represents the current price of milk is 3 + y in dollars

The initial price of a gallon of milk = $2.65

The price rose y dollars after the last hurricane

Then the expression will be

2.65 + y

Then the price dropped $0. 15

2.65 + y - 0.15

Add the terms

2.65 + y - 0.15 = 2.5 - y

later rose again by $0. 5

2.5 + y + 0.5

Add the terms in the expression

2.5 + y + 0.5 = (2.5 + 0.5) + y

= 3 + y

Current price of milk = 3 + y in dollars

Hence, the expression represents the current price of milk is 3 + y in dollars

Answer:

13x-12y+6xy

Step-by-step explanation:

To  make this easier, we can rearrange these terms, and get

5x+8x-12y+2xy+4xy.

x and y just represent variables, so we can combine 5x and 8x to get 13x, and we can combine 2xy and 4xy to get 6xy.

Now we have 13x-12y+6xy, and nothing else can be combined.

The ordered pair that is not a solution to the inequality y ≥ 2x² - 4x + 2 is given as follows:

(-1,6).

The inequality is presented as follows:

y ≥ 2x² - 4x + 2.

Then for each pair, the numeric value is calculated, replacing x and y by it's respective coordinates, and when a false statement is generated, the ordered pair is not a solution to the inequality.

For the first ordered pair, (-1, 6), the numeric value of the inequality is given as follows:

6 ≥ 2(-1)² - 4(-1) + 2

6 ≥ 8.

Which is a contradiction, hence it is not a solution to the inequality.

For the pair (1,0), we have that:

0 ≥ 2(1)² - 4(1) + 2

0 ≥ 0.

Which is true, hence it is a solution.

For the pair (0,3), we have that:

3 ≥ 2(0)² - 4(0) + 2

3 ≥ 2

Hence it is also a solution.

For the pair (2,5), we have that:

5 ≥ 2(2)² - 4(2) + 2

5 ≥ 2

Hence it is also a solution.

The equation in point-slope form of a line that passes through the points (5, −3) and (−2, 9) is

y + 3 = -12/7(x - 5)

Given, a line that passes through the points (5, −3) and (−2, 9).

Now, we have to find the equation of the line in point-slope form.

As, we know to find the equation of a line,

(y - y1)/(x - x1) = (y1 - y2)/(x1 - x2)

Now, using the above formula, we get

(y + 3)/(x - 5) = (-3 - 9)/(5 + 2)

(y + 3)/(x - 5) = -12/7

On cross-multiplying, we get

y + 3 = -12/7(x - 5)

At least 10 people or guests could go to a party and the second caterer is $250 cheaper to hire.

In the question we can use the equation :

  Y = mx + b ,  which is the slope-intercept form of the equation of a straight line. Here, m is the slope of the line and b is the intercept, x and y represent the distance of the line from the x-axis and y-axis, respectively.

For caterer A, the cost per guest is $15. This is the m value. The b value is the additional fee for setting up the tables, $100.

Here, the equation will be  y = 15x + 100     -------------------------(1)

For Caterer B, the cost per guest is $20. The b value is the additional fee for setting up the tables $50.

For this the equation will be : Y = 20X + 50.  --------------------- (2)

To find the number of guests that will result in an equal cost, set the equations equal to one another. Solve for x.

                    15x + 100 = 20x + 50        ---------------------- (3)

solving the equation (3),

   15x - 20x = 50 - 100

⇒ -5x = - 50

⇒ x = 10

Putting x = 10 in equation (1),

   15 × 10 + $100 = $250

Therefore, the cost of 10 people or guest will attend the party and the second caterer is $250 cheaper then the first caterer.
