24 because every 1 cup of flour equals 24 number of cookies so it keeps on adding up eg. 6 cups of flour would equal 144 cookies.

In mathematics, the system of equations is typically solved using the substitution method. In this approach.

The first step is to solve the equation for one variable and then insert the variable's value into the other equation.

x+y=20 ___ (1) and x=10 ___ (2) are given. x = 20-y is what we get from equation 1. To determine the value of y, substitute this value in equation 2. Now, substitute the value of y in equation 1, and we obtain x=15, which corresponds to x+5=20.

In algebraic expressions, substitution refers to the process of replacing the variables (letters) with their numerical values. The expression's total value can then be calculated.

The product of (4y - 3)(2y²+ 3y - 5) is 8y³+ 6y²- 29y+15.

The product of two numbers is the result you get when you multiply them together. So 12 is the product of 3 and 4, 20 is the product of 4 and 5, and so on. The term "product" refers to the result of one or more multiplications.

Given expression is

(4y - 3)(2y²+3y-5)

⇒ 4y(2y²+3y-5) -3(2y²+3y-5)

⇒ 8y³+ 12y²- 20y - 6y²- 9y + 15

⇒ 8y³+ 6y²-29y+15

The probability that Mrs. Barnes checks homework if the students take a pop quiz is 0.77, the correct option is D.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

Given;

Mrs. Barnes’s class determined the probability that she will check homework on a randomly chosen day is 0.42;

They also determined the probability that she will give a pop quiz when she checks homework is 0.6, and the probability that she will give a pop quiz when she does not check homework is 0.9;

Then the probability that Mrs. Barnes does not check homework if the students take a pop quiz;

P= 0.42*0.60 + 0.58*0.90

P = 0.252 + 0.522

P = 0.774

P ≈ 0.77

Therefore, the probability will be 0.77

The line's slope is -6, and its y-intercept is 2. In this equation, the slope is the value of x, which is -6, and the y-intercept is the value of b, which is 2. This is known as the slope-intercept format.

All linear equations, with the exception of vertical lines, cross the y-axis at a certain location known as the y-intercept. When our linear equation is written as y = m x + b, the slope-intercept form, the value of b is the value of the y-intercept.

The equation of the line if the y-intercept i (0,6) and the lope i 15 is:

B. y = 15x 6

The equation of the line is given in slope-intercept form (y = mx + b) where m is the slope and b is the y-intercept. The y-intercept is the point where the line crosses the y-axis and is given as (0,6). Therefore, the value of b is 6. The slope is given as 15. Therefore, the equation of the line is y = 15x + 6. This equation means that for every unit increase in x, y increases by 15 units and the line passes through the point (0,6)

This method is applicable for other equations as well, as long as they are in slope-intercept form (y = mx + b). The slope-intercept form is a way to represent a linear equation where the slope and the y-intercept are known. If the equation is not in that form, it can be rearranged to make it so. Once the equation is in slope-intercept form, you can identify the slope and the y-intercept which can be useful in understanding the characteristics of the line such as its direction and position in the coordinate plane.

What is the rectangular prism?

A rectangular prism is a three-dimensional geometric shape with six rectangular faces. It is also known as a rectangular cuboid, or simply a cuboid. It has three dimensions: length, width, and height. It can be represented by the formula: V = lwh where l is the length, w is the width, and h is the height.

We can use the formula for the volume of a rectangular prism to solve this problem. The formula is:

V = l * w * h

where V is the volume, l is the length, w is the width, and h is the height. We know that the volume of the box is 35 cubic inches and that the length and width are 2 inches each. So we can substitute those values into the formula and solve for h:

35 = 2 * 2 * h

To find h, we'll divide both sides of the equation by 4.

h = 35/4 = 8.75

Hence, the height of the popcorn box is 8.75 inches.

To make a 360mL mixture that contains 9% vinegar, use 288 mL of the first brand and 72 mL of the second brand.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, A chef is going to use a mixture of two brands of Italian dressing. The first brand contains 8% vinegar, and the second brand contains 13% vinegar. The chef wants to make 360 milliliters of a dressing that is 9% vinegar.

to set up an equation that will match the word problem. Let's call the amount of the first brand, F, and the amount of the second brand, S.

We want the total mixture to be 360mL so: F + S = 360

Also, you want the total mixture to contain 8% vinegar so:

.08F + .13S = .09(360)

Now, we can solve the system of equations using substitution.

F + S = 360

.08F + .13S = .09(360)

F = 360 - S      [solve 1st equation for F]

.08(360 - S) + .13S = .09(360)    [substitute into 2nd equation]

28.8 -0.08s+0.13s = 32.4

0.05s = 3.6

S = 72

F + 72 = 360     [substitute answer for S back into original equation]

F = 288

y=(0.88)^4t

y=1( (0.88)^4 )^t

y=1( 0.59969536 )^t

Set 0.59969536 equal to 1-r and solve for r

1-r = 0.59969536

-r = 0.59969536-1

-r = -0.40030464

r = 0.40030464

r = 0.40

The given equation y = 3x-5 is of the form y = mx+b

Parallel lines have the same slope, which means the answer also has a slope of 3.

Plug in the given point (x,y) = (-4,5) along with the slope m = 3 so we can determine the y intercept.

y = mx+b

5 = 3*(-4)+b

5 = -12+b

5+12 = b

17 = b

b = 17

We go from y = mx+b to y = 3x+17 as the final answer.

H₂ is two moles.

The molecular mass of an element is described as the sum of the masses of all the atoms present in the molecule.

Molecular mass is acquired by adding the atomic masses of all atoms with the number of atoms in the molecule.

H₂ has two atoms, so a mole of H₂ would have 1 mole of H₂ molecules, and when broken down into atoms, 2 moles of atoms.

Think about it like pairs of shoes. If you have 6 pairs of shoes, you have 12 pairs of shoes.

CO₂ has 3 atoms, 2N₂0 has 3 atoms, and there are already 2 moles, so that would be 6 moles of atoms; 2NaCl has 2 atoms but again, that 2 indicates that you'd have 4 moles of atoms, and H₂SO₄ has 7 atoms.

To find the area of an equilateral triangle with side 12 cm, we can use the formula:

Area = (√3/4) * (side length)^2

Substituting the value of the side length, we get:

Area = (√3/4) * 12^2

Area = (√3/4) * 144

Area = (√3/4) * 1212

Area = (√3/4) * 1212 = (√3/4)144 = (√3)12(12/4) = (√3)123 = 1212*√3 cm^2
