Quick Answer:

The order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction), should be followed to obtain the correct result.

The answer is -8

Explanation:

PEDMAS stands for :

P = Parentheses

E = Exponents

M = Multiplication

D = Division

A = Addition

S = Subtraction

So,

-3(2) = -6

2^2 = 4

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.

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.

A possible second point with a y-coordinate of 8 is equal to 5.

In Mathematics, the slope of a straight line can be calculated by using this this mathematical expression;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

From the information provided above, we have the following slope and data points on the line:

Points on x-axis = (1, 2).

Points on y-axis = (_, 8).

Slope, m = 3/2

Substituting the given points into the slope formula, we have the following;

Slope, m = (y₂ - y₁)/(x₂ - x₁)

3/2 = (8 - 2)/(x₂ - 1)

3/2 = 6/(x₂ - 1)

Cross-multiplying, we have:

3(x₂ - 1) = 12

x₂ - 1 = 12/3

x₂ - 1 = 4

x₂ = 4 + 1

x₂ = 5

In conclusion, we can logically deduce that the second point (x₂) is 5.

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 measure of the missing side lengths of the triangle is adjacent side = 5 and hypotenuse =  5√2.

What are trigonometric ratios?

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle.

To find the side of a right triangle:

A right-angle triangle has one of its angles as 90 degrees.

Therefore,

using trigonometric ratios,

tan 45 = opposite/adjacent

tan 45 = opposite / 5

opposite side = (tan 45)  * 5

opposite side = 1 * 5 = 5

Therefore,

adjacent side = 5

sin 45 = opposite / hypotenuse

1/√2  = 5 / hypotenuse

hypotenuse = 5√2 /1

hypotenuse =  5√2

Hence, the missing side lengths of the triangle are adjacent side = 5 and hypotenuse =  5√2.

Answer:

21/10

Step-by-step explanation:

42/20

divide both numerator and denominator by 2

=21/10

So, none of these sides can be the sides of a right triangle.

In a right triangle, one of the sides is the hypotenuse and the other two sides are called legs. The hypotenuse is always the longest side and the side opposite the right angle. The two legs are the shorter sides and the sides that form the right angle.

In the given triangle 2.5 cm, 6.5 cm, 6cm none of these sides can be the sides of a right triangle because according to the Pythagorean theorem, In a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

So, for a right angled triangle with legs of 6cm and 6.5cm the hypotenuse must be greater than 6.5cm and smaller than sqrt(6^2 + 6.5^2) = 8.66cm but the hypotenuse is 2.5cm which is less than 6.5 cm. So it is not a right triangle.

It is important to note that in a right triangle, one of the angles is always 90 degrees and is called the right angle. The side opposite to the right angle is the hypotenuse and the other two sides are the legs.

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 distance of the given point ( -3 , 5 ) from y - axis is equal to 3 units in the left direction ( negative x-axis).

As given in the question,

Given coordinates points in the coordinate plane is given by :

( - 3 , 5 )

Let us consider a horizontal line with the given coordinates on y - axis.

Coordinates on y-axis of the horizontal line are:

( 0 ,5 )

Distance between ( -3 ,5 ) and ( 0 , 5 ) is equal to :

= √ ( 5 - 5)² + ( 0 -(-3))²

= √ 9

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

Answer:

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

The term is also used to describe any type of exponential decay in general.

Given that a rock that originally had a mass of 1.00 gram.

The formula of decay is

Putting A₀ = 1.00 gram, A(t) = 0.50 gram, ti = half life = 4.5  billions = 4500000000.

0.50 = 1 (0.5)^(t/4500000000)
