Answer:
The perimeter of a rectangle has the general formula P=2L+2W. Since you know P and L, you can plug those values into the formula and solve for W.
Hope this answer is right!!
Answer:
Width: 13
Area: 42
Step-by-step explanation:
A rectangle has equal opposite sides, so if you know one side, you know that the opposite side will be the same. Then you can subtract it from the perimeter, and divide the remaining number in half because it represents the other opposite sides. If you were trying to find the area, do that to find the length and width. 29x13=42, so the area is 42. If you were trying to find the width, that would be 13 because
29+29=58
84-58=26
And 26/2=13

Answer:
x=13.84
Step-by-step explanation:
3x + 5x + 5x = 180 degree (sum of interior angles of a triangle is always 180 degeree)
13x = 180
x=180/13
x=13.84
therefore value of x is 13.84 degree

Answer:
w = 16, x = 11, y = 6, z = 7.5
Step-by-step explanation:
The scale factor is the ratio of corresponding sides, image to original.
scale factor = [tex]\frac{6}{8}[/tex] = [tex]\frac{3}{4}[/tex]
Then by proportion
[tex]\frac{12}{w}[/tex] = [tex]\frac{3}{4}[/tex] ( cross- multiply )
3w = 48 ( divide both sides by 3 )
w = 16
----------------
[tex]\frac{x}{12}[/tex] = [tex]\frac{3}{4}[/tex]
4x = 36
x = 9
-------------------
[tex]\frac{4.5}{y}[/tex] = [tex]\frac{3}{4}[/tex]
3y = 18
y = 6
----------------------------
[tex]\frac{z}{10}[/tex] = [tex]\frac{3}{4}[/tex]
4z = 30
z = 7.5

3. (05.02 LC) You can draw a quadrilateral with no parallel lines and at least one right angle. (1 point) True or False
======================================================
Explanation:
If you have exactly one right angle, then it is possible to have no parallel lines. See the diagram below. Refer to the upper figure.
If you had exactly 2 right angles, then that would form a trapezoid. A trapezoid has exactly one pair of parallel lines.
If you had 4 right angles, then it would form a rectangle. Any rectangle is a parallelogram, so we have 2 pairs of parallel lines by this point.
It's not possible to have a quadrilateral with exactly 3 right angles (and the fourth angle is some non-right angle). This is because all four angles of any quadrilateral must add to 360 degrees.

The value of a car is deprecting at the rate of 12% Find the correct value of car when cost of car was rs 350000 last year
Answer:
The cost of the car is $ RS 308,000.
Step-by-step explanation:
Given that the value of a car is deprecting at the rate of 12%, to find the correct value of car when cost of car was $ RS350,000 last year, the following mathematical calculation must be performed:
100 - 12 = 88
88/100 = 0.88
350,000 x 0.88 = X
308,000 = X
Therefore, the cost of the car is $ RS 308,000.

Step-by-step explanation:
a) Given,
Total marks in English = 90
Marks scored by James = 60
Therefore,
Percentage of marks scored
[tex] = \frac{60}{90} \times 100[/tex]
= 66.67% (approx. )
Then,
Total marks in Science = 150
Marks scored by James = 78
Therefore,
Percentage of marks scored
[tex] = \frac{78}{150} \times 100[/tex]
= 52%
At last,
Total marks in Maths = 120
Marks scored by James = 75
Therefore,
Percentage of marks scored
[tex] = \frac{75}{120} \times 100[/tex]
= 62.50%
b) In English test James scored highest percentage.

Solution:
Using formula:

In the numerator part common the value 4x and in the denominator we common the value 2 then:
[tex]\to \frac{4x^2+ 4x}{2x^2-2}= \frac{4x(x+ 1)}{2(x^2-1)}\\[/tex]
[tex]= \frac{4x(x+ 1)}{2(x^2-1^2)}\\\\= \frac{4x(x+ 1)}{2(x-1)(x+1)}\\\\= \frac{4x}{2(x-1)}\\\\= \frac{2x}{(x-1)}\\\\[/tex]

The correct answer is (2 x)/(x - 1).
To simplify.
(4 x²+ 4 x)/(2 x²-2) = 4 x(x + 1)/2(x² - 1)
By this formula
(x² - 1²) = (x + 1)(x - 1).
4 x(x + 1)/2(x + 1)(x - 1) = (2 x)/(x - 1).
Therefore, simplification of (4 x²+ 4 x)/(2 x²-2) is (2 x)/(x - 1).

Find the value of x in the isosceles triangle shown below
Answer:
x²+4² =8²
x²+16 =64
x² =64-16.
x² =48
x. =√48
answer is option D
Answer:
D
Step-by-step explanation:
The segment x is a perpendicular bisector and divides the triangle into 2 right triangles.
Using Pythagoras' identity in either of the 2 right triangles, then
x² + 4² = 8²
x² + 16 = 64 ( subtract 16 from both sides )
x² = 48 ( take the square root of both sides )
x = [tex]\sqrt{48}[/tex] → D

Answer:
C. [tex]9\pi[/tex]
Step-by-step explanation:
We proceed to solve for [tex]x[/tex] by the Pythagorean Theorem:
[tex](x+1)^{2} = (x-1)^{2} + (2\cdot x - 4)^{2}[/tex] (1)
[tex]x^{2} + 2\cdot x + 1 = (x^{2}-2\cdot x + 1) + (4\cdot x^{2}-16\cdot x + 16)[/tex]
[tex]x^{2} + 2\cdot x + 1 = 5\cdot x^{2}-18\cdot x + 17[/tex]
[tex]4\cdot x^{2} -20\cdot x + 16 = 0[/tex]
[tex](2\cdot x)^{2} -10\cdot (2\cdot x) + 16 = 0[/tex]
[tex](2\cdot x -8)\cdot (2\cdot x -2) = 0[/tex]
There are two different solutions:
[tex]x_{1} = 4[/tex], [tex]x_{2} = 1[/tex]
A solution of [tex]x[/tex] is considered realistic when the length of every side of the triangle is a not negative number.
[tex]x_{1} = 4[/tex]
[tex]UV = 2\cdot (4) - 4[/tex]
[tex]UV = 4[/tex]
[tex]WU = 4 - 1[/tex]
[tex]WU = 3[/tex]
[tex]WV = 4 + 1[/tex]
[tex]WV = 5[/tex]
[tex]x_{2} = 1[/tex]
[tex]UV = 2\cdot (1) - 4[/tex]
[tex]UV = -2[/tex]
[tex]WU = 1 - 1[/tex]
[tex]WU = 0[/tex]
[tex]WV = 1 + 1[/tex]
[tex]WV = 2[/tex]
The only realistic set of solutions is for [tex]x = 4[/tex], and the radius of the circle is represented by the line segment [tex]WU[/tex]: [tex]r = 3[/tex]
And the area of the circle ([tex]A[/tex]) is calculated from the following formula:
[tex]A = \pi\cdot r^{2}[/tex]
[tex]A = \pi\cdot (9)[/tex]
[tex]A = 9\pi[/tex]

Answer:
si
Step-by-step explanation:
cuando sumamos la medida de un ángulo en el par con el otro ángulo en el par, el total será 180 grados.
No, the student is not correct. Because sum of a pair of adjacent angles not always sum up to 180°.
What are adjacent angles?Adjacent angles are those angles that are always placed next to each other in such a way that they share a common vertex and a common side but they do not overlap each other.
The sum of the measures of a pair of adjacent angles can be any number, including 180 degrees, but it does not have to be 180 degrees.

Volume left in container A=
20
ml
Answer:
volume left in A is 80ml
Step-by-step explanation:
let original volume in both be x ml
after pouring from A to B
vol in A = x - 120
vol in B = x + 120
now it is given that
vol in B = 4 times vol in A
implies
[tex]x + 120 = 4 \times (x - 120) \\ x + 120 = 4x - 480 \\ 3x = 600 \\ x = 200[/tex]
hence original volume in A is 200ml. after pouring in B it is 200-120 = 80 ml
