Lee drew five rectangles as shown on this coordinate grid
Given:
Lee drew five rectangles as shown on this coordinate grid .
To find:
The correct statement.
Solution:
From the given diagram, it is clear that,
Dimensions of rectangle x are 6 by 3 units.
Dimensions of rectangle A are 7 by 3 units.
Dimensions of rectangle B are 6 by 3 units.
Dimensions of rectangle C are 3 by 6 units.
Dimensions of rectangle D are 6 by 4 units.
Dimensions of rectangle x and B are same and clearly it can be translation or rotation about the origin.
Dimensions of rectangle x and C are same but only rotation is not sufficient to get rectangle C from rectangle x.
Dimension of rectangle x, A and D are different, so they are not congruent and we cannot get rectangle A and D by rotation, reflection and translation.
Therefore, the correct option is B.
You have 22 books in your library. Eight are romance novels, 4 are murder mysteries and the rest are science fiction. Only 15 books will fit on a book shelf. How many ways can you arrange the books?
Answer:
The books can be arranged in 170,544 ways
Step-by-step explanation:
This is a combination question since we are arranging
We simply want to find the number of ways to select 15 books out of 22 for arrangement
Mathematically, that will be;
22 C 15 = 22!/(22-15)!15! = 170,544 ways

Rena spent 6 days reading her book completing the same fraction of the book each day if she had a total of 8/9 of her book after 6 days what fraction of the book did she react each day
Answer:
The fraction of the book that Rena read every day is [tex]\frac{4}{27}[/tex]
Step-by-step explanation:
Rena spent 6 days reading her book completing the same fraction of the book every day and you want to know the fraction of the book she read each day. Knowing that Rena had a total of 8/9 of her book read after 6 days, then you simply divide the total amount of the book read during those days by 6, the number of days:
[tex]\frac{8}{9}[/tex]÷6
To divide a fraction by a whole number, you must convert the whole number into a fraction, finding the reciprocal of that fraction, and multiply it by the first fraction. That is, you must find the reciprocal of the number that is after the division symbol; and then you multiply the first number (the one before the division symbol) by the reciprocal of the second number (the one after the division symbol). Remember that to find the reciprocal of a number, you simply have to change the numerator and denominator of the number.
Since 6 can be considered to be a fraction equal to [tex]\frac{6}{1}[/tex], by inverting the number, then you get [tex]\frac{1}{6}[/tex]
Then:
[tex]\frac{8}{9}[/tex]÷6= [tex]\frac{8}{9} *\frac{1}{6}[/tex]
Now you multiply the numerators and denominators of the fraction to get the new numerator and denominator of the final solution.
[tex]\frac{8}{9}[/tex]÷6= [tex]\frac{8}{9} *\frac{1}{6}=\frac{8*1}{9*6} =\frac{8}{54}[/tex]
Finally, simplifying the fraction:
[tex]\frac{8}{9}[/tex]÷6= [tex]\frac{8}{9} *\frac{1}{6}=\frac{8*1}{9*6} =\frac{8}{54}=\frac{4}{27}[/tex]
So:
[tex]\frac{8}{9}[/tex]÷6= [tex]\frac{4}{27}[/tex]
The fraction of the book that Rena read every day is [tex]\frac{4}{27}[/tex]
What is the slope of the line through (-1, 4) and (1, -2)
Answer:
Slope = -3
Step-by-step explanation:
The slope is the change in y over the change in x
The slope formula is m=y₂-y₁/x₂-x₁ (y over x)
So, plug in your coordinates (the subscript represents the order in which your points are going to be subtracted in)
So, you would get m=-2-4/1-(-1)
Simplify (first subtract the top, then subtract the bottom)
This would get you to -6/2 (remember your rules: a negative and a negative makes a positive)
-6/2 would get you to -3

=5-3/5-1
=2/4
=1/2
Step-by-step explanation:
The best way to solve these is by making them into a equation, rise over run, or y over x.
[tex] \frac{3}{1} - \frac{5}{5} [/tex]
You will get the same answer nomatter which order these are values are in. Now, solve for this equation.
[tex] \frac{ - 2}{ - 4} [/tex]
Now this is negative and kind of messy, although, we can turn both values into positive values without the answer changing, just be careful on other problems with this technique as it doesn't always work.
[tex] \frac{2}{4} [/tex]
Now we can simplify again.

The total length of a beach is 13.2 kilometers. If lifeguards are stationed every 0.6 kilometers, including one at the end of the beach, how many lifeguards will there be on the beach?
Answer:
22 including one at the end of the beach
Step-by-step explanation:
Total length of the beach = 13.2 kilometers
If lifeguards are stationed every 0.6 kilometers, INCLUDING one at the end of the beach
Number of lifeguards in the beach = Total length of the beach / distance interval of each lifeguards
= 13.2 kilometers / 0.6 kilometers
= 22
Number of lifeguards in the beach = 22 including one at the end of the beach
Elena mixes 5 cups of apple juice with 3 cups of sparkling water to make sparkling apple juice. For a party, she wants to make 35 cups of sparkling apple juice. How much of each ingredient should Elena use? Explain or show your reasoning.
Answer:
25 cups of apple juice and 10 sparkling water
Step-by-step explanation:
There are 7 cups of sparkling juice in each batch, since 5 + 2 = 7. То make 35 cups Elena will need 5 batches since 5 x 7 = 25. 5 batches mean 25 cups of apple juice and 10 cups of sparkling water

Shryia read a book cover to cover in a single session, at a constant rate. After reading for 1.5, point, 5 hours, she had 402 out of the total 480 pages left to read.
Answer:
y = -52x + 480
Step-by-step explanation:
Let us assume the number of pages left be x
And, the number of hours is x
According to the question
Data given is as follows
Number of hours 1.5 and 5
Total pages 480
Left pages 402
Based on the above information,
The computation is shown below;
Pages read by Shriya in 1.5 hours is
= Total pages in the book - left pages to read
= 480 pages - 402 pages
= 78 pages
And, there is 1.5 hours
So in one hour she read
= 78 pages ÷ 1.5 hours
= 52 pages per hour
So, the equation is
y = -52x + 480
