The side of a square is 2.5 find its perimeter and area
Answers
6.25 is the area 2.5^2=6.25
Answer:
perimeter = 10
area = 6.25
Step-by-step explanation:
Every square has four equal sides. If we know one side is 2.5, then all sides are 2.5.
2.5*4 = 10
To find the area of a square you multiply the height and length. Since all sides of a square are the same, you just multiply 2.5 with itself.
2.5*2.5=6.25

A license plate consists of 3 letters followed by 1 digit. How many license plates are possible if the first letter can be any letter except I or O, the digit cannot be 0, and no letters or digits may repeat
Answers
Answer:
85
Step-by-step explanation:
So you know that there are 26 letters in the alphabet and 3 letters in the license plate, so that would be 26 multiplied by 3 to cover all of those letters. The first letter can't be I or O, so you subtract 2 from the product. 26 times 3 is 78, minus 2 is 76. There are 10 single digits, but only one in the plate and it can't be 0. This leaves 9 digits so you add that to the total number.
76 + 9 = 85
I hope this helps! :)
Sorry for my previous answer, I misread the question, but this is the correct answer now, hope this helped!
Answer:
129600 license plates
Step-by-step explanation:
This time, we will use an option of solving where we take the number of possibilities for one letter, then multiply it by the next, then multiply it by the next, then multiply it by the number of possibilities for the number. We would have 24 letters to start (not including I or O), then after we pick one, we need to remove it since we can't repeat letters. So just for our letters, we would get:
24 * 25(only the first digit can't have I or O) * 24
Then, we need to multiply that by 9 (since we are not including 0), giving us:
24 * 25 * 25 * 9 = 129600
Meaning, we can have 129600 different license plates.

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%

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

Answers
An equation in slope-intercept form of the amount of money saved after x weeks is y=21x+213.
What is the slope intercept form?The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.
The standard form of the slope intercept form is y=mx+c.
Given that, after 17 weeks, you have $570, and after 29 weeks, you have $822.
Here, (17, 570) and (29, 822)
Substitute (x₁, y₁)=(17, 570) and (x₂, y₂)=(29, 822) in m=(y₂-y₁)/(x₂-x₁)
= (822-570)/(29-17)
= 252/12
= 21
Substitute, m=21 and (x, y)=(17, 570) in y=mx+c, we get
570=21×17+c
570=357+c
c=213
Substitute, m=21 and c=213 in y=mx+c, we get

Jason and Marie both travel 300 miles. Jason drove at an average speed of 10 miles per hour faster than Marie and made the trip in one hour less time. Find the average speeds of both cars.
Answers
Answer:
jason: 60mph
marie: 50mph
Step-by-step explanation:
let jason drive at x miles per hour
let marie drive at x-10 miles per hour
let jason drive for y hours
let marie drive for y+1 hours
distance = speed * time
for jason:
300 = x * y
for marie:
300 = (x-10) * (y+1) = x*y + x - 10y -10
300 = x*y
divide both sides by x to solve for y
300/x = y
plug this into the second equation
300 = (x-10) * (300/x+1) = 300 -3000/x +x -10
300 = 300 -3000/x +x -10
subtract 300 from both sides
0 = -3000/x + x - 10
multiply both sides by x to get rid of the denominator
0 = x^2 -10x -3000
factor
0 = x^2 - 60x +50x -3000
0 = x(x-60) + 50(x-60) = (x+50)(x-60)
x = 60 or -50
x cannot be negative so x = 60mph

An indirect proof is an argument that begins with the assumption that a conclusion is false, then uses logical reasoning to show that the assumption leads to a contradiction.
What does the phrase "in contradiction" mean?a fact or assertion that contradicts what someone else said or that differs from another fact or assertion to the point where one of them must be incorrect.
What is an illustration of contradiction?A situation or set of ideas that contradict one another is called a contradiction. A contradiction would be saying out loud that you support the environment while never remembering to empty the recycling. A statement that contains opposing ideas is frequently referred to as a "contradiction in terms."

Which of these is the absolute value parent function?
A. f(x) = x
OB. f(x) = 2ˣ
OC. f(x) = x²
OD. f(x) = Ixl
Answers
Option D) f(x) = |x|, is Correct.
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
C. f(x) = x² is the quadratic function, it's a parabola opening upwards and not an absolute value function
D. f(x) = |x| is the absolute value function, V-shape and it's an example of the absolute value parent function.

The Space Needle elevator can hold a maximum of 4,500 pounds. Twenty-five people need to use the elevator. Arian had some measures from the data set of how much each person weighed. Which measure would be most useful to determine if the people can safely use the elevator?
Answer choices
Mode
Mean
interquartile range
Median
Answers
The measure that would be most useful to determine if the people can safely use the elevator is B. Mean
How to illustrate the information?The most useful measure to determine if the people can safely use the elevator would be the mean weight of the people, as it would give an idea of the average weight of the group and if it is below 4,500 pounds.
The mode is the most common value in a set of data and does not give information about the weight of the entire group. The interquartile range is a measure of the spread of the middle 50% of the data and does not give information about the average.
In conclusion, the correct option is B.

Find the 35th term for the sequence: 12, 9.5, 7, 4.5...
Answers
Answer:
-73
Step-by-step explanation:
So to begin you must find where you start on a graph. To do this you can go backwards from your first number and in this situation it would be 14.5 because the slope is -2.5x. I will use y as the answer.
y=-2.5x+14.5
From here you plug in how many terms are neeeded for the correct answer. In this situation there is 35 terms needed.
y=-2.5(35)+14.5
Solve this equation to get your answer.
y=-73
Answer:
The 35th term is - 73.----------------------------
Given sequence:
12, 9.5, 7, 4.5...This is an AP with the common difference of:
d = 4.5 - 7 = 7 - 9.5 = 9.5 - 12 = - 2.5The first term is a = 12.
Use the nth term equation to find the 35th term:
aₙ = a + (n - 1)da₃₅ = 12 + (35 - 1)(- 2.5) = 12 - 34*2.5 = 12 - 85 = - 73How do you solve inequalities in 7th grade?

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.
