Answers
Answer:
v = 1/5, 7/3
Step-by-step explanation:
Factor the following 15v² + 7 = 38v
Solution:-15v² + 7 = 38v
15v² - 38v + 7 = 0
15v² - 3v - 35v + 7 = 0
3v(5v - 1) - 7(5v - 1) = 0

Answer:
x = 1.5
Step-by-step explanation:
Here, we want to solve for the value of x
By using the tangent from the same point theorem, we have it that;
lh^2 = lj * lk
1^2 = (0.5) * (0.5 + x)
1 = 0.5x + 0.25
1-0.25 = 0.5x
0.5x = 0.75
x = 0.75/0.5
x = 1.5
A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 12 feet. The width of the floor is 4 feet less than the length. It will have a stage and a closet, and the remaining area of the floor will be painted. The dimensions are shown in the diagram:
Let A represent the painted area, in square feet, of the floor. Choose the correct equation to solve for area (A).
A = x(x − 4) − 0.5(8)(x − 4) − 4(8)
A = x(x − 4) − (8)(x − 4) − 4(8)
A = x(x − 4) + (8)(x − 4) + 4(8)
A = x(x − 4) + 0.5(8)(x − 4) + 4(8)
Answers
Step-by-step explanation:

Answer:
A. A = x(x - 4) - 0.5(8)(x - 4) - 4(8)Step-by-step explanation:
Total area:
A(t) = x(x - 4)Area of the stage:
A(s) = 0.5(8)(x - 4)Area of the closet:
A(c) = 4(8)Area to be painted:

Will a 11.5-inch x 18-inch rectangular tray fit in
the box shown? Explain.
Answers
Answer:
Option D
Step-by-step explanation:
From the picture attached,
In the parallelogram ABCD,
Length of diagonals AC and BD are equal.
By the property,
"If the lengths of the diagonals of a parallelogram are equal, parallelogram will be a rectangle".
Therefore ABCD is a rectangle.
That means all interior angles of the given rectangle will be 90°.
Now we apply Pythagoras theorem in right triangle ΔABC,
AC² = AB² + BC²
(22)² = (12)² + (BC)²
484 - 144 = (BC)²
BC = √340
BC = 18.44 inches
Dimensions of the given box are 12 inches by 18.44 inches.
Dimensions of the rectangular tray is 11.5 inches by 18 inches.
Since, dimensions of the box are larger than the dimensions of the tray, tray can be adjusted in the box.
Therefore, Option D will be the answer.

Answers
Given:
A figure.
To find:
The value of x.
Solution:
Draw two parallel lines as shown in the below figure.
If a transversal line intersect two parallel lines, then alternate interior angles are same.
[tex]a=20[/tex] (Alternate interior angle)
[tex]d=b[/tex] (Alternate interior angle) ...(i)
The value of angle d is
[tex]d=50-a[/tex]
[tex]d=50-20[/tex]
[tex]d=30[/tex]
Using (i), we get
[tex]b=30[/tex]
If a transversal line intersect two parallel lines, then same sides interior angles are supplementary angles.
[tex]c+140=180[/tex]
[tex]c=180-140[/tex]
[tex]c=40[/tex]
Now,
[tex]x=b+c[/tex]
[tex]x=30+40[/tex]
[tex]x=70[/tex]
Therefore, the value of x is 70.

(6x - 7y)(6x + 7y)
Step-by-step explanation:
36x² - 49y² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
36x² - 49y²
= (6x)² - (7y)²
= (6x - 7y)(6x + 7y)
Answer:
(6x + 7y)(6x - 7y)
Step-by-step explanation:
36x² - 49y²
= (6x)² - (7y)²
= (6x + 7y)(6x - 7y)
In this question we used the identity-
a² - b² = (a + b)(a - b)

A teacher calculated the mean of 27 students mark to be 62. A student who later completed the assessment got a mark of 53. What is the new mean of the class, to two decimal places?
Answers
Answer:
first of all the average score of students is 62.
and there are 27 students
so full marks scored by students are 27×62= 1674
and 1 new students added to that so his score would be 1674+ 53(his marks)= 1727
so now the mean of students are beause there are one more students so 27+1 = 28 then 28÷1727= 61.6 is the mean now
