Answer:

To reflect a triangle across the y-axis, you need to negate the x-coordinate of each vertex.

The original triangle with vertices (1, 3), (2, 5), and (4, 3) will be reflected across the y-axis to become a new triangle with the following vertices: (-1, 3), (-2, 5), and (-4, 3).

Keep in mind that a reflection across the y-axis means that the object is flipped along the y-axis. Therefore, the x-coordinate of each vertex is multiplied by -1, which flips the object horizontally.

The 95.2 kilograms of potatoes  by the shop order. With the unit sign kg, the kilogram serves as the International System of Units' unit of mass.

A shop sells potatoes and carrots

let c = carrots

let p = potatoes

let TW = Total weight

The shop orders 50.4 kg more potatoes than carrots

p = 50.4 kg + c

Total weight = Mass of p + Mass of c

TW = 50.4 kg + c + c = 50.4 kg + 2c …. (i)

32% of the total weight is carrots

c = (32 /100 )  * Total weight = 0.32 TW

TW = c / 0.32 …. (ii)

50.4 kg + 2c = c / 0.32

Multiply all through by 0.32

16.128 + 0.64c = c

c -  0.64c  = 16.128

0.36 c = 16.128

c = 16.128 / 0.36 = 44.8 kg

Potatoes = 50.4 kg + c = 50.4 kg + 44.8 kg = 95.2 kg

Hence, the answer is 95.2 kg ordered by the shop.

13 units is the distance from the given point (-12, 5) to the origin.

Both statistical and qualitative methods can be used to determine how far apart two things or points are.

The word "distance" in physics can refer to an actual length or, more frequently, to an estimate based on a range of other factors.

The length of the line segment that connects any two points on a plane provides the distance between those spots.

To calculate the distance between two points, one commonly uses the equation d=((((x2 - x1)2 + (y2 - y1)2).

So, the given point is:

(-12, 5)

Assume that O (0, 0) is the origin and that M (-12, 5) is the provided location.

The distance between M and O is:

= √(−12−0)2+(5−0)2

= √(−12)2+(5)2

= √144+25

= √169

= √13×13

= 13 units

Therefore, 13 units is the distance from the given point (-12, 5) to the origin.

The number that represent the product of ac is 18 and the sum of b is -9 .

The factored form of the trinomials is (x-3)(x-6)

An algebraic statement with three on-zero terms separated by + or - is called a trinomial. A trinomial exists when three monomials are separated by addition or subtraction. The formula for a quadratic trinomial is ax² + bx + c, where a, b, and c are real, non-zero values.

An algebraic statement with variables and constants is a quadratic trinomial. It is written as ax² + bx + c, where a, b, and c are real non-zero values and x is the variable. Leading coefficient "a," linear coefficient "b," and additive constant "c" all refer to the same constant. A quadratic trinomial is also used to explain the discriminant D, which is expressed as D = b² - 4ac and determines the quantity of an expression. The discriminant aids in categorizing the many quadratic trinomial instances. A quadratic equation, such as ax² + bx + c = 0, is one in which the value of a quadratic trinomial with a single variable is zero.

The trinomial is x² - 9x + 18

In the expression ax² + bx + c

here a = 1,  b = -9 and c = 18

The term that represent the product of ac = 1* 18 = 18

The term represent the sum of b = -9

Factoring The trinomial we get,

x² -9x + 18

= x² - 3x - 6x + 18

= x(x-3) -6(x-3)

The speed of Mr. Black to his friend's house is 60 miles per hour.

Speed is the unit rate in terms of distance travelled by an object and the time taken to travel the distance.

Speed is a scalar quantity as it only has magnitude and no direction.

Speed = Distance travelled / Time taken

Let x be the speed of Mr. Black to his friend's house.

Let d be the distance in miles that Mr. Black travelled to reach friend's house.

Time taken to reach friend's house = 2 hours

x = d / 2 ⇒ d = 2x

Speed of Mr. Black during return is 20 mph slower.

Speed during return = x - 20

The trip back took 1 hour longer.

Time = 2 + 1 = 3 hours

x - 20 = d / 3

Substituting d = 2x in the above equation,

x - 20 = 2x / 3

No, the ordered pair (-2, 2) is not a solution of the linear inequality because it does not satisfy the inequality.

An ordered pair is a pair of numbers that are related to each other in a specific order. An ordered pair can be used to represent a point on a graph. In order for an ordered pair to be a solution of a linear inequality, it must satisfy the inequality. This means that the ordered pair must make the inequality true when it is substituted into the equation. For example, if the linear inequality is "x + 2 > 3," then for (-2, 2) to be a solution, it must make the inequality true. This would mean that -2 + 2 > 3, which is not true, so (-2, 2) is not a solution of the linear inequality.

The distance Joe climbed up the ladder is c.

3.22 + b2 = 2.42 is the correct equation.

What is the Pythagoras theorem?

The Pythagorean theorem is a fundamental concept in geometry and mathematics, named after the ancient Greek mathematician Pythagoras. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides (the legs).

3.22 + b2 = 2.42 is the correct equation that represents the situation of Joe's position on the ladder. It uses the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the ladder) is equal to the sum of the squares of the lengths of the other two sides (the horizontal and vertical distances from the base of the ladder to Joe's feet). In this case, c is the distance that Joe climbed up the ladder, and b and a are the horizontal and vertical distances, respectively.

So, by solving the equation:

3.22 + b2 = 2.42

b = √ (2.42 - 3.22)

Then use the Pythagorean theorem again to find the length of the ladder (c)

c = √(3.22 + b^2)

Hence, the distance Joe climbed up the ladder is c.

You should expect to draw a consonant about 560 times.

Step-by-step explanation:

The word FOOTBALL has 5 consonants - F, T, B, L and L. Therefore, you should expect to draw a consonant 5 times out of every 8 draws. 5/8 = 0.625, so for 840 draws you should expect to draw a consonant approximately 840 x 0.625 = 560 times.

The number of times you should expect to draw a consonant is 525.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Given that,

The letters from the word FOOTBALL are written on 8 cards with one letter on each card.

One card will be drawn randomly and then placed back into the stack.

Number of consonants in the word = 5 [F, T, B, L and L]

Total number of letters = 8

Probability of finding consonant each time = 5/8

If this experiment is repeated 840 times,

Number of times you should draw a consonant = 840 × (5/8) = 525

Step-by-step explanation:

Here, 4 teams given. Each teams has played every other teams 4 times.

so here we will name each team

team a = bulls

team b = lakers

team c = knickers

team c = warriors

So to find total number of games, we know that Bulls played with the other 3 teams by 4 times that is (4×3) = 12, Lakers played with the other two teams by 4 times that is (4×2) = 8, Knicks played with Warriors 4 times.

Therefore, total number of games = .

Total points given, for Bulls = 22, for Lakers = 19, for Knickers = 14, for Warriors = 12.

So sum of total points =

For a win a team earned 3 points and for a tie two teams win 1 point.

That means for tie total point = 1+1 = 2.

Let's take total number of game which ended as win played be x and total number of game which ended as a tie be y.

We have got total number of games is 24.

So we can write the equations as,

.......Equation 1

And also we have got total number of points is 67. So the equation is,

.......Equation 2

From equation 1, if we move x to the right side we will get,

Now let's substitute this value in equation 2, to get the value of x. By substituting the value we will get,

We will expand 2 now.

We will move 48 to the other side by subtracting it from both sides. We will get,

So the number of games which ended as a win = 19

The number of games which ended as a tie = 24 -19 =5
