Answer:
The perimeter of the square is 10 cm.
The area of the square is 6.25 cm.
Step-by-step explanation:
To find perimeter, add all the sides.
2.5 + 2.5 + 2.5 + 2.5 = 10
To find area, multiply the length by the width. Since Nadia drew a square, all the sides will have the same measurement (2.5 cm, in this case). So, simply multiply 2.5 by 2.5, knowing that the length and width of the square are the same size.
2.5 × 2.5 = 6.25
The area of Square is 6.25 cm² and Perimeter of Square is 10 cm.
what is Area and Perimeter of Square?The Area of Square is the product if its side
i.e., Area of square = side x side
and, perimeter of square = 4 x side
Given:
Side of Square= 2.5 cm
then , area of Square= side x side
= 2.5 x 2.5
= 6.25 cm²
and, Perimeter of Square= 4 x side
= 4 x 2.5
= 10 cm

Jethro used dimensional analysis to convert one rate of speed to another. Two of the conversion factors he used are 5280 ft/1 mi and 1 hr/60 min. What could be the units of the initial rate of speed and the final rate of speed? Justify your answer.
The units of the initial and final rates of speed are;
Initial rate of Speed = ft/hr
Final rate of speed = mi/min
We are told that the conversion factors he used are;5280 ft/1 mi and 1 hr/60 min
Now, the meaning of 5280 ft/1 mi denotes that;5280 ft mile is equivalent to 1 mile
This means that the initial distance unit used was ft while the final one was mile
Also, 1 hr/60 min denotes that;
1 hour is equivalent to 60 minutes.
This means that the initial time units used was hour while the final one was minute.
In conclusion, since we know the initial time and distance units used, we can say that the initial rate of speed ft/hr while final speed rate was miles/minutes.Read more at; https://brainly.com/question/17734333

At the beginning of the week, Aksa’s parents deposited $20 into Aksa’s lunch account. The amount of money Aksa had left after each day is shown in the table, where x is the number of days and y is the remaining balance.
a. What are the x- and y-intercepts?
b. What do the x- and y-intercepts represent?
Here we need to plot x and y co-ordinates from the given table.
What are x and y co-ordinates and intercepts ?This is 2D co-ordinate geometry here we have an x axis and a y axis we use co-ordinate geometry to plot lines and curves according to the gives question.when the question consist of linear equations they form straight lines and when questions consists of quadratic and higher degree polynomials they form curves.
a. Here the the days are represented by x and remaing balance are represented by y.
So, when x = 0, y = 20 is co-ordinate form we can represent this as (0,20)
similarly the other co-ordinate points are (1,16), (2,12), (3,8), (4,4), (5,0).
b. x- and y- intercepts represnts the value of one variable corresponding to the other variable.

What is the total price of a $45.79 item when a 7% taxe is added
Answer:
$42.58
Step-by-step explanation:
You would multiply the price of the item (45.79) by the percentage as a decimal (0.07) and subtract the product.
in this case:
45.79x0.07 = 3.205 (rounded 3.21)
45.79-3.21 = 42.58

If 15% of 4x is 20 less than x, what is the value of x?
The sentence "15% of 4x is 20 less than x"
translates to 0.15 • (4x) = x – 20
Solving that…
0.15(4x) = x - 20 multiplipy 0.15•4
0.6x = x - 20 subtract x from both sides
-0.4x = - 20 divide both sides by -0.4
x = 50

We require 2 equations with the repeating digit placed after the decimal point
let x = 1.555... (2) Multiply both sides by 10
10x = 15.555.... (2)
Subtract (1) from (2) thus eliminating the repeating digits
9x = 14 ( divide both sides by 9 )

Penny reads 11 pages in 1/3 hour. What is the unit rate for pages per hour? For hours per page?
Answer: 33
Step-by-step explanation:
Answer:
33 pages per hour
Step-by-step explanation:
1. To solve for how many pages Penny can read in one hour, we need to write a ratio of pages to hours.
[tex]11: 1/3 = x : 1[/tex]2. Now, 1/3 goes into one, three times. This means that 11 goes into x, three times. We can write "11 goes into x, three times" as: [tex]\frac{x}{11} =3[/tex].
3. (Solving x/11 = 3)
Step 1: Multiply both sides by 11
[tex]\frac{x}{11}*11=3*11[/tex] [tex]x = 33[/tex]Therefore, Penny read 33 pages per hour.
