Maurice has completed 72 pages of the research paper he is writing. That is 90% of the required length of the paper. What is the required length of the paper?
Answer:
its 100 pages ................
Answer:
80
Step-by-step explanation:
When we first look at this, it generally says "90% of what number is 72?" so that's what we can do.
We can change 90% into a decimal, and put in x, which is what our answer will be!
[tex]0.9*x=72[/tex]
We can multiply both sides of this equation by 100, and then divide by 90. After all of this, we have
[tex]x=72*10/9[/tex], which is 80.
5. The vertices of AABC are A(-5, 4), B(-2, 4), and C(-4, 2). If AABC is reflected across the y-axis, find the coordinates of the vertex C'.
Answer:
C'(4, 2)Step-by-step explanation:
The vertex C has coordinates:
x = - 4, y = 2If the triangle reflected over the y-axis, the y-coordinates of C and C' will be same but the x-coordinate will change to opposite.
So the vertex C' will have coordinates:

O A. AQRS ~ ATUV
B. AQRS = ATUV
C. AQRS= ATUV
O D. AQRS ATUV
The indication of QRS and TUV are similar is QRS ~ TUV.
What is Similarity?Similar triangles are triangles that have the same shape but differ in size. Similar items include all equilateral triangles and squares with any side length. In other words, if two triangles are identical, their corresponding angles and sides are congruent and in equal proportion. The " ~ " sign here denotes the resemblance of triangles.
The three-sided polygon is the triangle. The following is the criteria for triangle similarity:
Corresponding angles of both triangles are equal, and corresponding sides of both triangles are proportional to each other.
In Triangle QRS and TUV the similarity sign is used.
We know the ≅ is the sign of Congruence.
and, ~ is the sign of Similarity.
So, the sign of Similarity is QRS and TUV.

What is the slope of the line that passes through the points (-7, -2) and (-15, -14)
The slope of the line that passes through the points (-7, -2) and (-15, -14) is 3/2.
The given coordinate points are (-7, -2) and (-15, -14).
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)
The slope of the line is
Put (x1, y1) =(-7, -2) and (x2, y2)=(-15, -14)
Slope = m= (-14-(-2))/(-15-(-7))
= -12/(-8)
= 3/2
Therefore, the slope of the line that passes through the points (-7, -2) and (-15, -14) is 3/2.

in the school library there are 4850 Hindi and English books if the Hindi books are 42% find the number of English books in the library
Answer:
2813 English books
Step-by-step explanation:
Hindi books are 42% of 4850
42 ÷ 100 = 0.42
0.42 × 4850 = 2037 Hindi books
number of English books = total number of Hindi and English books - number of hindi books
4850 - 2037 = 2813 English books

Find five consecutive odd integers if the sum of the first three integers is 7 more than the sum of the last two.
Answer: 15, 17, 19, 21, 23
Step-by-step explanation:
You can let the middle number = x, then the numbers are
x-4, x-2, x, x+2, x+4
Plugging it back in to what is given,
x-4+x-2+x = 7+x+2+x+4
3x-6 = 2x + 13
x = 19
The numbers are 15, 17, 19, 21, 23
The first odd integer is 15, and the five consecutive odd integers are 15, 17, 19, 21, 23
What is Sequence?Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
Let x be the first odd integer, then the next four odd integers would be x+2, x+4, x+6, and x+8.
According to the problem, the sum of the first three integers is 7 more than the sum of the last two, which can be expressed mathematically as:
x + (x+2) + (x+4) = (x+6) + (x+8) + 7
Simplifying the equation, we get:
3x + 6 = 2x + 21
Subtracting 2x and 6 from both sides, we get:
x = 15
Therefore, the first odd integer is 15, and the five consecutive odd integers are 15, 17, 19, 21, 23

Ms. reed makes salad dressing by combining oil and vinegar. she combines 8 fluid ounces of oil and 3 fluid ounces of vinegar to make one batch. Ms. Reed makes 3 batch of salad dressing. How many total cups of salad dressing does she makes ?
By performing a change of units, we will see that she did make 1.375 cups of salad dressing.
How many total cups does she make?First, we know that she combines 8 oz of oil and 3 oz of vinegar, then the total volume in ounces is:
V = 8oz + 3 oz = 11 oz
Now we want to know how many cups there are in 11 ounces, so we need to perform a change of units.
We know that:
1 oz = 0.125 cups
Then we can write:
11 oz = 11*(1 oz) = 11*(0.125 cups) = 1.375 cups
