Answer:

x = 8

y = 30

Step-by-step explanation:

10x + 6y = 260

5x + 7y = 250

we can use the elimination method by multiplying the second equation by -2 to get:

-10x - 14y = -500

now we can add them together:

10x + 6y = 260

-10x - 14y = -500

the 'x' will be eliminated and we have -8y = -240

y = 30

plug 30 into either equation to solve for 'x':

10x + 6(30) = 260

10x + 180 = 260

10x = 80

x = 8

Step-by-step explanation:

If You and a friend go to Tacos Galore for lunch and You order three soft tacos and three burritos and your total bill is $12. Cost of a soft taco is $2 and cost of a burrito is $2.

Let the cost of a soft taco = x

Let the cost of a burrito =y

You ordered 3 soft tacos and 3 burritos, so your bill = 3x + 3y = $12

Your friend ordered 4 soft tacos and 2 burritos, their bill =  4x + 2y = $10

Solving the two equations above:

3x + 3y = $12

4x + 2y = $10

Subtracting the second equation from the first:

x = $2 (Soft taco)

Solving for y, where x is $2

y = ($12 - 3x) / 3

y= ($12 - 3 * $2) / 3

y = $2 (cost of a burrito)

Therefore  Cost of a soft taco is $2 and cost of a burrito is $2.

The relation (0, 0), (2, 0), (2, 2), (3, 4) and (6, 6) is not function.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

(0, 0), (2, 0), (2, 2), (3, 4) and (6, 6).

Now, we now that any relation is said to be function if the every input value have their corresponding value and the input value should be distinct.

So, there is no two input values repeat.

Then, the given relation is not a function because in the relation the same input value 2 have output 0 and 2.

Hence, the relation is not function.

By solving an algebraic equation we will see that Mike needs to use 30 pounds of the $5 jelly beans.

Mike wants to mix beans worth $5 per pound with 10 pounds of jelly beans worth $2 per pound to get a mixture that he can sell for $4.25 per pound

If he uses x pounds of the $5 beans, then we can write the equation:

x*$5 + 10*$2 = (10 + x)*$4.25

And now we can solve that equation for x.

$5*x + $20  = $42.50 + $4.25*x

$5*x - $4.25*x = $42.50 - $20

$0.75*x = $22.50

x = $22.50/$0.75

x = 30

So Mike needs to use 30 pounds of the $5 beans.

The candle's height after 16 hours is 20.4 - 1.6, or 18.8 centimeters.

Let Y = height

Let X = time

Y = mX + b, where m is the slope and b is the y-intercept, denotes the linear relationship between height and time.

We can determine the slope using the data (8,20.4) and (19,18.2)

Slope = (y2 - y1) / (x2 - x1) = (18.2 - 20.4) / (19 - 8) = -2.2 / 11 = -0.2

This indicates that the candle's height is decreasing at a rate of 0.2 cm each hour.

Since 16 hours are 8 hours after the initial data point of (8,20.4), the height will decrease in the 8 hours between hour 8 and hour 16 by 8 * (-0.2) = -1.6 cm.

The candle's height after 16 hours is 20.4 - 1.6, or 18.8 centimeters.

A variable operates as a stand-in for an equivocal value. In mathematics, variables are used to establish general equations that are later built in with specific values.

What are equations, and what various sorts are there?

Identity equations and dependent equations are the two sorts of equations. All feasible values of the variables result in an identity. Only certain pairings of the variables' values make a conditional equation true. Two expressions coupled by the equals symbol ("=") form an equation. A formula would be 3x - 5 = 16, for reference. When this equation is solved, we realize that the value of the variable x is 7.

The graphs of y = -1/3x + 2 and y = 3x - 5 are neither parallel nor perpendicular. The slopes are -1/3 and 3, which are not the same, so the lines are not parallel, and their product is not -1, so the lines are not perpendicular.

What is a triangle?

Triangles are polygons in geometry that have three sides and three vertices. This figure is two-dimensional and has three straight sides. A triangle is a three-sided polygon. A triangle's three angles added together equals 180°. A single plane contains the triangle. The triangle is classified into six forms based on its sides and angles.

A triangle is categorized into three categories based on its sides, namely:

Scalene Triangle - Each side has a distinct length.

Isosceles Triangle - A triangle with two sides of equal length and one side of a different length.

Equilateral Triangle - A triangle has three sides that are of the same length.

A triangle is categorized into three categories based on its angles, namely:

Acute Angle Triangle - A triangle with all of its angles smaller than 90°.

Obtuse Angle Triangle - A triangle with one of its angles larger than 90°.

Triangle with a Right Angle - A triangle with one of its angles equal to 90°.

Subtract 90 from 180, which is 90 degrees.

Then you get the equation of 2x+56 = 90 for which the 2 represents the split between the 90 degrees and the +56 is the 56 degrees higher than the smaller angle.

Solving this gives you x = 17 degrees, which is the small angle.

For 17+56 = 73 = larger angle

17+73 = 90 plus the other 90 gives you 180 total.

Answer:

The smallest angle is 17°

Step-by-step explanation:

All the angles add up to 180°. Use this to write an equation.

x = smallest angle

x+56 = not the smallest angle

90 = the right angle

x + x+56 +90 =180

combine like terms

2x + 146 = 180

subtract 146

2x = 34

divide by 2

x = 17

The smallest angle is 17°.

[tex]P(X=x)=C_{n,x} .p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} =\frac{n!}{x!(n-x)!}[/tex]

And p is the probability of a success on a single trial.

24 products means that n=24

3.2% are defective, thus p=0.032

The probability that 2 or fewer are defective is:

P(X≤2)=P(X=0)+P(X=1)+P(X=2)

In which P(X=0)=0.4582

P(X=1)=0.3635

P(X=2)=0.1382

0.9599 = 95.99% probability that the company will find 2 or fewer defective products in this batch.

The probability that 4 or more are defective is:

P(X<4)=P(X=0)+P(X=1)+P(X=2)+P(X=3)

=0.4582+0.3635+0.1382+0.0335

P(X≥4)=1-P(X<4)

0.0066 = 0.66% probability that 4 or more defective products are found in this batch.

Answer: There will be approximately 1154.6 people attending.

Step-by-step explanation:

To find out how many people will be attending in 4 years, we can use the formula:

Attendance(future) = Attendance(current) * (1 - rate)^time

Where:

Attendance(current) = 1200 people

Rate = 0.5% (as a decimal = 0.005)

Time = 4 years

So, Attendance(future) = 1200 * (1 - 0.005)^4

Attendance(future) = 1200 * 0.99^4 = 1200 * 0.9605 = 1154.6 people

So, in 4 years, there will be approximately 1154.6 people attending.
