Moon and stars- 7 1/2
softballs- 7.4
stripes- 7 3/5
tie-dye- 7.9
Indicate which of the fabrics Jessica can and cannot use to make all of the book bags for her friend.
moons and stars can or cannot
softballs can or cannot
stripes can or cannot
tie-dye can or cannot
The fabric that she cannot use is the softballs.
Which fabric can she not use?A proper fraction is a non-integer that is made up of a numerator that is smaller in value than the denominator. A mixed fraction is a fraction that is made up of an integer and a proper fraction. An example of a mixed fraction is 1 7/8.
The first step is to determine the total amount of fabric needed for the 4 friends : 1 7/8 x 4
15/8 x 4 = 60 /8 = 7 1/2 yards
The second step is to convert the mixed fractions to decimals, by dividing the numerator by the denominator and adding the integer.
7 1/2 = 7.5
73/5 = 7.6
The fabric that cannot be used as the fabrics that are less than 7.5 yards.

A group of friends wants to go to the amusement park. They have $89.50 to spend on parking and admission. Parking is $7.75, and tickets cost $27.25 per person, including tax. Write and solve an equation which can be used to determine pp, the number of people who can go to the amusement park.
Answer:
7.75 +27.25p = 89.50p = 3; 3 people can go the the amusement parkStep-by-step explanation:
Given parking costs $7.75 and admission costs $27.25, you want an equation and its solution for the number of people (p) who can go to the amusement park for $89.50.
EquationThe equation relates the total of costs to the total of funds available. The cost will be the total of 7.75 for parking and 27.25p for admission for p people.
7.75 +27.25p = 89.50
SolutionThis 2-step equation is solved by subtracting 7.75, then dividing by the coefficient of p.
7.75 +27.25p = 89.50 . . . . . equation
27.25p = 81.75 . . . . . . . . . . . subtract 7.75

What is the Term for an answer that was obtained in a fair or controlled test
Suppose we draw a single card from a deck of 52 fair playing cards. what is the probability of drawing an ace or a two?
The probability of getting an Ace is 1/13.
Probability of an event = number of favorable outcomes for the event/number of all possible products.
First, let's calculate the number of all possible outcomes. Randomly picking the cards could result in each of the 52 being selected. So, there are 52 possible outcomes.
But if you want an Ace in your desired event, you have four options—ace of Spades, Ace of Clubs, Ace of Hearts, and Ace of Diamonds. Therefore, the number of favorable outcomes for Aces = 4.
Therefore,
The probability of getting an Ace with a deck of 52 cards = 4/52 = 1/13.

How to solve an equation?To solve linear equations, utilize the steps that are provided below.
Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12
⇒ 7z – 3z + 4 = 12
⇒ 4z = 12 – 4
⇒ 4z = 8
⇒ z = 8/4
⇒ z = 2

WRITING IN MATH Explain why the order of the vertices is important when naming congruent triangles. Give an example to support your answer.
Because we are saying that the angles/edges in corresponding positions for each triangle are congruent.
Consider the triangle congruence statement below:
△ABC≅△DEFThis is actually a collection of six—yes, six—congruence statements.
They are as follows:
∠A≅∠D∠B≅∠E∠C≅∠FAB≅DEAC≅DFBC≅EFAs an example, consider the first congruence: ∠A≅∠D
This is implied by the fact that A and D are both listed first in their triangles (in the statement △ABC≅△DEF ). Similarly, B and E are in second place, so that's how we get ∠B≅∠E.A similar logic applies to the sides that have corresponding vertices.If the triangle congruence statement was as follows:
△ABC≅△FED
Then,
∠A would-be congruent to ∠F∠B would be congruent to ∠E∠C would be congruent to ∠DWe can see how changing the order of the triangle names changes which angles/edges are implied to be congruent.
This is why we must be cautious to name the triangles in the correct order. Otherwise, we risk claiming that two angles (or line segments) are congruent when they are not.Therefore, we are saying that the angles/edges in corresponding positions for each triangle are congruent.

X-2
In mathematics, an inequality is a relation which makes a non-equal comparison between the two numbers or other mathematical expressions. Inequalities have no solution are X>X, -4+X>-2+X.
What do you mean by inequality?An inequality compares two values, showing if one is less than, greater than, or simply not equal to the another value.
The a ≠ b says that a is not equal to bThe a < b says that a is less than bThe a > b says that a is greater than b (those two are known as strict inequality)The a ≤ b means that a is less than or equal to bThe a ≥ b means that a is greater than or equal to b.Inequalities are governed by following properties. All of these properties also hold if all of non-strict inequalities (≤ and ≥) are replaced by their corresponding strict inequalities (< and >) and — in case of applying a function — monotonic functions are limited to the strictly monotonic functions.

What is the inscribed of a circle?An inscribed angle of a circle is an angle whose vertex is a point A on the circle and whose sides are line segments (called chords) from A to two other points on the circle.
An octagon is known to be a type of polygon that is said to have up to 8 sides. the octagon is an 8-sided polygon, also called 8-gon, in a two-dimensional plane. A regular octagon will have all its sides equal in length. Each interior angle of a regular octagon is equal to 135°. Therefore, the measure of exterior angle becomes 180° – 135° = 45°.

Beau buys a 3-pound of trail mix for a hike. he wants to make one-ounce bag of trail mix for his friends with whom he is hiking how many one-ounce bags can he make?
Using conversion, Beau can make 48 one-ounce bags of trail mix from the 3-pound trail mix he bought for the hike.
To know how much one-ounce bags of trail mix can he make from the 3-pound trail mix, convert first the amount of trail mix in pounds to ounce.
In mathematics, conversion is the process of changing the value of one form or unit to another. It can be changing ones unit of length, weight, volume or even currency to another.
Converting pounds to ounce,
1 pound = 16 ounces.
If Beau has 3 pounds of trail mix, equivalently, converting pounds to ounces, he has:
1 pound = 16 ounces
3 pounds = 3(16 ounces)
3 pounds = 48 ounces
If he wants to make one-ounce bag of trail mix from the 3-pound of trail mix (= 48 ounces), divide it by one ounce to get how many bags he can make.
number of one-ounce bag = 48 ounces/1 ounce

Vertical Angles are congruent in measure.
Therefore, Angle FHC is also 87°.
A trapezoidal deck has dimensions as shown.
a. What is a formula for the area of this trapezoid?
What is the Area of Trapezoid?
The area of a trapezoid is the total space covered by its sides. An interesting point to be noted here is that if we know the length of all sides we can simply split the trapezoid into smaller polygons like triangles and rectangles, find their area, and add them up to get the area of the trapezoid. However, there is a direct formula that is used to find the area of a trapezoid if we know certain dimensions.
Area of Trapezoid Formula :
The area of a trapezoid can be calculated if the length of its parallel sides and the distance (height) between them is given.
The formula for the area of a trapezoid is expressed as,
A = 1/2 (a +b) h
where (A) is the area of a trapezoid, 'a' and 'b' are the bases (parallel sides), and 'h' is the height (the perpendicular distance between a and b)
