Jayden scored more than 2/3 the number of points Kenneth scored. If Jayden scored 24 points, which inequality solution represents , the number of points Kenneth could have scored?
Answer:The answer would be A. 1 1/5
48/40 = 1 8/40
1 8/40 Simplify to 1 1/5
Hope this helps!
Final answer:
To find the inequality for the number of points Kenneth could have scored if Jayden scored more than 2/3 of Kenneth's points when Jayden scored 24 points, we create the inequality 24 > (2/3)k and solve for k to find that the number of points that Kenneth scored is less than 36.
Explanation:
The student is asking how to represent an inequality where Jayden scored more than 2/3 of the points that Kenneth scored. If Jayden scored 24 points, we want to find the inequality solution for the number of points, k, that Kenneth could have scored.
To represent this inequality, we start by establishing that Jayden scored more than 2/3 of Kenneth's points, so we have:
24 > (2/3)k
Now we want to solve for k to find the range of values that Kenneth could have scored. Multiplying both sides of the inequality by 3/2 to isolate k, we get:
(3/2) * 24 > k
Which simplifies to:
36 > k
Therefore, the number of points Kenneth could have scored must be less than 36.

Answer: Spores for the first box. Plant for the second box
Step-by-step explanation:
I got the answer right
Here, we are required to complete the statements to describe sporulation and vegetative propagation.
(1). Spores
(2). Plant
Sporulation essentially refers to the formation of spores from vegetative cells during unfavorable environmental conditions. Consequently, offsprings develop from these tiny structures called Spores. Sporulation is therefore often described as an adaptive response that allows the organism to survive under harsh conditions of radiation, extreme heat or cold, malnutrition etc.Vegetative propagation is characterized as any form of asexual reproduction occurring in plants in which a new plant develops from a fragment of the parent plant or a specialized reproductive structure (such as grafting and budding).Read more:

What is completing square method?Write the equation in the form, such that c is on the right side.
Step 2: If a is not equal to 1, divide the complete equation by a such that the coefficient of x2 will be 1.
Step 3: Now add the square of half of the coefficient of term-x, (b/2a)2, on both sides.
Given equation:
x² - 4x - 32 = 0
Now, add and subtract (2)² we get
x² - 4x - 32 + 2² - 2² = 0
x² - 4x + 2² - 32 - 2² = 0
(x-2)² -36=0
(x-2)²= 36
(x-2) = ±6
x= +6+2, -6+2
x=8,-4

Each school (input) has one principal (output). Function or non function?
Answer:
Function
Step-by-step explanation:
A function is any equation that doesn't have a repeat of any outputs. Since no principal can be a principal of more than one school, it's a function.
Each school having one principal is an example of a mathematical function because there is a one-to-one relationship between schools (inputs) and principals (outputs), meeting the definition of a function with a unique output for each input.
Explanation:In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. When we consider the example of schools and principals, we can apply this concept to determine if it represents a function. If each school (input) has one and only one principal (output), it satisfies the criteria for a function. This is because there is a one-to-one relationship between schools and principals. No school has more than one principal, hence adhering to the definition of a function with a domain (schools) and a range (principals).
Furthermore, the concept of functions is foundational to various aspects of school systems, which goes beyond mathematics and extends into the social functions of education. For instance, schools act as socialization agencies teaching respect for authority and conformity to law, which is a manifest function. This educational function aligns with the structure of authority within schools where each principal is the head of their respective school.

The area of a triangle is 15 square centimeters. If all the dimensions of the triangle are multiplied by 5, what will be the area of the new figure?
please help :)
75 cm2 150 cm2 375 cm2 625 cm2
Answer:
375 cm2
Step-by-step explanation:
The new area of the triangle will be 187.5 square centimeters.
Explanation:To find the area of a triangle, you can use the formula A = ½ x base x height. Given that the area of the triangle is 15 square centimeters, we can set up the equation as 15 = ½ x base x height. We are told that all the dimensions of the triangle are multiplied by 5, so the new base and height will be 5 times the original dimensions. Substituting these values into the equation, we get 15 = ½ x (5 x base) x (5 x height). Simplifying the equation, we have 15 = 12.5 x base x height.
Therefore, the new area of the triangle is 12.5 times the original area, which is 15 x 12.5 = 187.5 square centimeters.
What is true about traversals, no matter how they go through the parallel lines?
Answer:
Transversals? Transversals are different from traversals.
Step-by-step explanation:
Transversals always go through parallel lines. Okay, here are the rules. All pairs of alternate interior angles, alternate exterior angles, and corresponding angles are congruent pairs if the lines the transversal intersects are parallel, in which case each pair of consecutive interior angles are supplementary. That’s four rules right there.
Here are four more. If any of those pairs is congruent or supplementary, the lines the transversal intersects are parallel.
Vertical angles are always congruent, and any two angles that form a linear pair are supplementary. When you know all these rules, you can take the measure of any angle in the diagram and determine the measures of all the other angles as long as the lines intersected by the transversal are parallel.

The length of a rectangle is three times the width. What is the perimeter of the rectangle if the width is 17 inches?
51 inches
136 inches
204 inches
68 inches
Answer:
136 inches
Step-by-step explanation:
One side of the rectangle is 17 and the other side can be 3x because it's 3 times the width
3x=3(17)
= 51 inches which is the length and 17 inches is the width
2(51)+2(17) because you are finding the perimeter
And the answer is 136 inches
Answer:
136 inches
Step-by-step explanation:
First multiply 17 by 3 which equals 51. Then multiply 17 by 2 which equals 34 and 51 by 2 which equals 120. Then when you add those to sums you get 136 inches.

Jody has four bottles of soft drink – one bottle of cola, one of root beer, one of ginger ale, and one of orange. She chooses three of these bottles to take to a party. If she chooses the ginger ale, what is the probability she also chooses root beer?
If Jody chooses the ginger ale, the probability that she also chooses root beer from her selection is 1/3.
Explanation:Jody has four bottles of soft drink: one bottle of cola, one of root beer, one of ginger ale, and one of orange. She chooses three of these bottles to take to a party. The question is, if she chooses the ginger ale, what is the probability she also chooses root beer?
Since Jody has already chosen the ginger ale, she now has to choose 2 more bottles from the remaining three (cola, root beer, and orange).
There are 3 choose 2 ways (which is 3 ways) for Jody to pick her remaining bottles.
Only one of these combinations includes root beer (ginger ale, root beer, and one of the others).
Therefore, the probability that she also chooses root beer, given she has chosen ginger ale, is 1/3.
