Step-by-step explanation:
Associative property of addition: Changing the grouping of addends does not change the sum. For example,
(2+3)+4= 2+(3+4)
No matter how you rearrange the numbers, they will always add to the same amount.

briana needs at least $680 to buy a new puppy. she has already save $400. she earns $8 an hour at her job. write and solve an inequality to find how many hours she will need to work to buy the puppy.
Answers
Answer:
680≤400+8h
280≤8h
35≤h
Step-by-step explanation:
400 is the constant, and h is your variable. Solve the inequality for h, number of hours worked. Briana must work at least 35 hours.
1) The equation below shows the height of a soccer ball, h(d) meter as a function of the
horizontal distance, d meters the ball travels until it hits the ground. The ball is kicked when
it is on the ground. h(d) = -0.025(d – 20)2 + 12
Always make a sketch to begin even if you are not asked to!
a) What is the maximum height of the ball?
b). What is the horizontal distance of the ball from the kicker when it reaches its maximum
height?
c) How far does the ball travel horizontally from when it is kicked until it hits the ground?
Answers
For the given equation
a)The maximum height of the ball is 12 meters.
b)The horizontal distance of the ball from the kicker is 20 meters.
c)The ball travels approximately 32.85 meters horizontally.
What does equation mean?An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides, the left-hand side (LHS) and the right-hand side (RHS), separated by an equal sign (=). The equation can contain variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. Solving an equation means finding the value(s) of the variable(s) that make the equation true.
According to the given informationa) The equation is in vertex form, where the maximum height is the y-coordinate of the vertex. We can see that the vertex is at (20, 12), so the maximum height of the ball is 12 meters.
b) The horizontal distance of the ball from the kicker when it reaches its maximum height is the x-coordinate of the vertex. In this case, the vertex is at (20, 12), so the horizontal distance of the ball from the kicker when it reaches its maximum height is 20 meters.
c) To find the distance the ball travels horizontally from when it is kicked until it hits the ground, we need to find the value of d when h(d) = 0. This is because the ball hits the ground when its height is 0. Setting h(d) = 0, we get:
0 = -0.025(d – 20)2 + 12
Solving for d, we get:
(d – 20)2 = 480
d – 20 = ±√480
d = 20 ± 4√30
Since the ball is kicked when it is on the ground, we only consider the positive value of d:
d = 20 + 4√30
Therefore, the ball travels approximately 32.85 meters horizontally from when it is kicked until it hits the ground.

what is the domain of the function, f(x)?
Answers
Answer:
B. 3≤x≤ 6
Step-by-step explanation:
When a question asks for the domain of a function, it is asking for all possible x-values. Look at the graph of the function- there are no points on the graph where x=1, so we know that C and D are definitely wrong since they include 1. The two that are left look very similar, but A means "3 is greater than or equal to x, x is greater than or equal to 6." This has to be wrong because it says that 3 is greater than 6, which is obviously incorrect. The only answer left is B, which is correct because it includes all possible x-values.
lmk if this is incorrect or hard to understand, hope this helps!!!

A group of friends wants to go to the amusement park. They have $201.75 to spend on parking and admission. Parking is $5.75, and tickets cost $24.50 per person, including tax. How many people can go to the amusement park?
Answers
Answer:
8 friends
Step-by-step explanation:
The group of friends will park only once, so you only need to add $5.75 once, but you still need to add the amount of money for all the people who are in the car, 24.50 x 8 is equal to exactly 196 dollars, so 196 + 5.75 is equal to exactly 201.75, which is the amount of money the group has, so 8 people can come.
Answer: The answer is 8 :)

Answer each question. Show your reasoning. a. 125% of e is 30. What is e? b. 35% of f is 14. What is f?
Answers
Answer: a. e= 24
b. f = 40
Step-by-step explanation:
a. 125% of e = 30
125/100 × e = 30
1.25 × e = 30
1.25e = 30
e = 30/1.25
e = 24
b. 35% of f = 14
35/100 × f = 14
0.35 × f = 14
0.35f = 14
