16 potatoes

according to the question:

we can formulate it as, (12*4)/3

= 48/3= 16

use the BODMAS rule to solve

that is Brackets Of Division Multiplication Addition Subtraction

so first (12*4) will be calculated.

multiply means adding equal groups

the first value that is used to multiply is called the multiplicand (12)

the second value that is been multiplied is called the multiplier. (4)

the result that we get when we multiply the multiplicand and the multiplier is called the product. (48)

then, divide the product with the denominator

48/3

The division is the process of splitting a specific amount into equal parts.

therefore, 16 potatoes are there.

The numeric value of the exponential expression in this problem is given by the following option:

A. 2^12.

The exponential expression for this problem is defined as follows:

8^x/2^y.

8 is the third power of 2, hence:

8 = 2^3.

When a term is elevated to two of it's powers, the powers are multiplied, hence:

(2^3)^x = 2^(3x).

Meaning that the exponential expression is then written as follows:

8^x/2^y = 2^(3x)/2^y.

When two terms of the same base and different exponents are divided, we keep the base and subtract the exponents, hence the expression is given as follows:

2^(3x)/2^y = 2^(3x - y).

As stated in the problem, the numeric value of the expression 3x - y is given as follows:

3x - y = 12.

Hence the entire expression is simplified as follows:

2^(3x - y) = 2^12.

Meaning that the correct option is given by option A.

The size of sample space is 8.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. This is the fundamental theory of probability, which is applied to the probability distribution.

Answer:

Step-by-step explanation:

The number of pounds of food that the pig ate every day, given that it was the same amount of food daily, was 3. 94 pounds per day

To find the food that the pigs ate each day, you first need to find the total number of pounds of food that Angela bought and this amount in total is :

= 250 + 145 + 200

= 595 pounds of food

The number of days from the start of November through March is :

= 30 days November + 31 days December + 31 days January + 28 Days February + 31 Days March

= 151 days in total

The amount of food that Angela's pigs ate per day is therefore:

= Total food purchased / Number of days

= 595 / 151

= 3. 94 pounds per day

Answer:

If there are 24 coins in total and some of them are nickels, then there must also be some dimes. Let's call the number of dimes "x" and the number of nickels "y". We know that y = 1/3 * x. We can set up an equation to represent this relationship: y + x = 24. We can also substitute 1/3 * x for y to get the following equation: 1/3 * x + x = 24. We can combine like terms to get: (4/3) * x = 24. We can divide both sides by 4/3 to solve for x: x = 18.

Therefore, there are 18 dimes in the bag.

The value of x and y are 5 and 3 respectively.

The value of x and y when (x , 2y) = (5, 6) can be found as follows:

Therefore, the x coordinates of the graph is given as 5 while the double of y coordinates is equals to 6. Then, we have to equate the values as follows:

x = 5

2y = 6

The value of x is known by mere equating.

Hence, let's find the value of y.

2y = 6

divide both sides of the equation by 2

2y / 2 = 6 / 2

The inverse of the function → f(x) = 2x + 5  is → f⁻¹(x) = (x/2) - (5/2).

Inverse of a function can be calculated by following the steps mentioned below -

According to the question, the equation given is as follows

y = f(x) = 2x + 5

y = 2x + 5

Replace 'y' with 'x', we get -

x = 2y + 5

Now, solve for y -

2y = x - 5

y = (x/2) - (5/2)

Replace 'y' with f⁻¹(x) -

f⁻¹(x) = (x/2) - (5/2)

Hence, the inverse of the function → f(x) = 2x + 5  is → f⁻¹(x) = (x/2) - (5/2).

The two equations that have the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p include the following:

B. 2.3p – 10.1 = 6.49p – 4

C. 230p – 1010 = 650p – 400 – p

From the information provided, we have the following equation:

2.3p – 10.1 = 6.5p – 4 – 0.01p

Next, we would simplify the given equation by collecting like terms as follows;

2.3p - 10.1 = 6.5p - 0.01p - 4 = 6.49p - 4

2.3p - 10.1 = 6.49p - 4

In Mathematics, the multiplication property of equality states that both sides of an equation will remain the same and equal, when both sides of the equations are multiplied by the same number.

By multiplying both sides of the given equation by 100, we have;

100 × (2.3p - 10.1) = 100 × (6.5p - 4 - 0.01p)

230p - 1010 = 650p - 400 - p

Using the pythagoras theorem to set the appropriate hypotenuse, perpendicular and base to make a right angled triangle, the correct option the would for a right angled triangle would be option c i.e 2, 2, [tex]\sqrt{8}[/tex].

A right angled triangle is a triangle in which one of the angles is a right angle (90 degrees). The side opposite the right angle is called the hypotenuse and the other two sides are called the legs or catheti. The two legs are perpendicular to each other and the hypotenuse is the longest side of the triangle. The Pythagorean theorem, which states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs, applies to all right-angled triangles.

The Pythagorean theorem states that in a right-angled 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 or catheti). This can be written as: c^2 = a^2 + b^2 where c is the length of the hypotenuse, and a and b are the lengths of the legs.

So applying the pythagorean theorem on  provided options to choose the best option for making a right angled triangle, we find that the option c suites best to form a right angled triangle as show below,
