Their recipe, which makes a pan of 15 cookies, lists these items: 1/2 cups of flour 2 eggs, 3 tablespoons butter, 3/4 cups sugar 1 package of chocolate drops They will make only full recipes, no partial recipes. They learn that a big concert is scheduled for the same night and attendance will be down 25%. How many recipes of cookies should they make for their smaller party? (Some eggs and some cookies may be left over. )
(A) 1.
(B) 2.
(C) 5.
(D) 7.
(E) 15
Answers
The correct option is option (E) 15
To calculate the number of cookies they will need, they first determine the number of students who will be attending the meeting. Since attendance is down by 25%, the number of students attending is 108*(1-0.25) students.
=108 students * 0.75 = 81 students.
To figure out the number of cookies they will need, they multiply the number of students by the number of cookies per student, which is 81 students * 2 cookies= 162 cookies.
Since each recipe makes 15 cookies, they need to make 162 cookies / 15 cookies/recipe = 10.8 recipes.
Since they cannot make partial recipes, they round up and make 11 recipes of cookies for their smaller party.
As 11 is not a given option, we consider the option which is greater than 11, which is 15.

What is parent function?
A parent function is a basic or fundamental function that serves as the starting point for a family or group of related functions. These functions can be obtained by applying a transformation to the parent function, such as shifting, stretching, or reflecting it.
The absolute value parent function is represented by the following function:
D. f(x) = |x|
The absolute value function is defined as |x| = x for x >= 0 and |x| = -x for x < 0. Graph of this function is a V-shape, and it's also known as "the absolute value of x" function. It is a reflection of the linear function f(x) = x across the x-axis and will always have a slope of 1 and a y-intercept of 0.
A. f(x) = x is a linear function, slope is 1 and y-intercept is 0, This is not absolute value function
B. f(x) = 2ˣ is the exponential function, and it is not an absolute value function

The equation of the linear function is A(t) = -975t + 15000
How to determine the equation of the functionFrom the question, we have the following parameters that can be used in our computation:
The table of values
From the table of values, we have:
A(t) t
11,100 4
7200 8
3300 12
From the above table of values, we can see that
As t increase by 4, the value of A(t) decreases by 3900
This means that the table of values is a linear relation, and the slope is
slope = -3900/4
slope = -975
A linear equation is represented as
y = mx + c
Where
slope = m
So, we have
A(t) = -975t + c
Using the points on the table, we have
11000 = -975 * 4 + c
Evaluate
c = 15000
So, we have
A(t) = -975t + 15000
Hence, the equation is A(t) = -975t + 15000

Point O is where the diagonals in a rhombus MNLP intersect. If the side is 8 inches long and the measure of the angle MNL is 120 degrees, then NP is 8 inches.
A rhombus is a quadrilateral with all of its sides being the same length and both pairs of opposite sides being parallel.

An item costs $430 before tax , and the sales tax is $34. 40. Find the sales tax rate. Write your answer as a percentage
Answers
The sales tax rate on the item = 8%
We know that the sales tax is nothing but the purchase price times the percentage of tax.
An item costs $430 before tax.
This means, the purchase price is 430 dollars.
The sales tax is $34. 40
To find: the sales tax rate as a percentage
First we find a ratio of the sales tax to the cost of the items before tax.
Sales tax / Pre-tax value of item = (34.40) / 430
Now we write a proportion where the pre-tax value is proportional to 100% and solve for the percentage of sales tax.
i.e., (34.40) / 430 = sales tax percent / 100
So, the sales tax percent = 8%
Therefore, the sales tax is of 8%

How do you solve inequalities in 7th grade?
Answers
Inequalities are mathematical expressions involving the symbols >, <, ≥ and ≤. To ‘solve’ an inequality means to find a range, or ranges, of values that an unknown x can take and still satisfy the inequality.
Suppose we want to solve the inequality x + 3 > 2.
We can solve this by subtracting 3 from both sides:
x + 3 > 2
x > −1
So the solution is x > −1. This means that any value of x greater than −1 satisfies x + 3 > 2.
Inequalities can be represented on a number line such as that shown in the image attached below. The solid line shows the range of values that x can take. We put an open circle at −1 to show that although the solid line goes from −1, x cannot actually equal −1.
