Which of the following statements about a rhombus is not true?
A rhombus is a parallelogram.
A rhombus has two sets of parallel sides.
A rhombus has four sides of equal length.
A rhombus has four right angles.
Answer:
„A rhombus has four right anglesv” → is not true.Step-by-step explanation:
This is a parallelogram. It is a quadrilateral with two pairs of parallel sides. Here, the opposite angles are alternate, that is, they have togheter 180°.
Rhombus
This is a rhombus. It is a quadrilateral whose four sides all have the same length. Here, the diagonals of a rhombus intersect at equal angles.
A rhombus has opposite angles equal and the figure formed by joining the midpoints of the sides of a rhombus is a rectangle, and vice versa. It has an inscribed circle.
Good luck:)
The sum of two numbers is 12 and there diffrence is 8 find the 2 numbers
Answer:
10 and 2
Step-by-step explanation:
a + b = 12
a - b = 8
let 'a' = 8 + b
substitute:
8 + b + b = 12
2b + 8 = 12
2b = 4
b = 2
a must be 10 then

-2x=x^2-6−2x=x 2 −6minus, 2, x, equals, x, squared, minus, 6 1) Rewrite the equation by completing the square.
Answer:
(x+1)² = 7
Step-by-step explanation:
Given the expression
-2x = x² - 6
Rewrite
x² - 6 + 2x = 0
x²+2x-6 = 0
Add 6 to both sides
x²+2x-6+6 = 0+6
x²+2x = 6
Add square of half of coefficient of x to both sides
Coefficient of x = 2
Half of Coefficient of x = 2/2 = 1
Square of half of Coefficient of x = 1² = 1
Add 1 to both sides
x²+2x + 1= 6 + 1
Factorize the LHS
x²+x+x + 1 = 7
x(x+1)+1(x+1) = 7
(x+1)(x+1) = 7
(x+1)² = 7
hence the equation rewritten by completing the square method is
(x+1)² = 7
y = -5x+1
y = 3x – 2
Is (3.8) a solution of the system?
Answer: No, 3.8 is not a solution.
Step-by-step explanation:
Set -5x+1 equal to 3x-2
-5x+1=3x-2 subtract 3x making it -8x+1=-2 subtract one from both sides and get -8x=-3 divide by -8 and get -3/-8 which equals in decimal form 0.375
Check it
plug in 0.375 for X
-5(0.375)+1= -0.875
3(0.375)-2 = -0.875
It checks out ^_^
please helpppppp asap (triangle inequality theorem) show the work
Answer:
a - yes
b - no
Step-by-step explanation:
triangle inequality theorem - the sum of any 2 sides of a triangle must be greater than the measure of the third side
For a
5 + 4 must be greater than 7 for the set to be measures of the sides in a triangle
5 + 4 = 9
9 is greater than 7 therefore 4,5, and 7 can be measures of the sides in a triangle
For b
3 + 2 must be greater than 6 in order for the set to be measures of the sides in a triangle
3 + 2 = 5
5 is less than 6 therefore 2,3 and 6 can not be measures of the sides in a triangle
A man's salary is increased by $925 to $1036. Find the percentage increase. What would have been his new salary if the increase had been 16%
Answer:
See the solutions below
Step-by-step explanation:
Initial Salary= $925
Final salary= $1036
% increase= Change/initial *100
substitute
% increase= 1036-925/925 *100
% increase=111/925 *100
% increase=0.12 *100
% increase=12%
2. Let us find 16% of $925
=16/100*925
=0.16*925
=$148
Hence the salary would have been
=148+925
=$1073

[tex] \dfrac{c}{\sin 28^\circ} = \dfrac{2~yd}{\sin 36^\circ} [/tex]

Identify the slope and the y-intercept of the following equation 1/2x - 1 = y
b =
m =
uto: Which is the “first point” given, the slope or the y-intercept ?
Answer:
see below
Step-by-step explanation:
Our equation is y = 1/2x - 1. This mirrors our standard linear parent function of y = mx + b.
m is the slope and b is the y-intercept.
From this, we can see that
m = 1/2
and
b = -1.
The first point given is the y-intercept because with y-intercepts, we know the coordinates right away. A y-intercept's coordinates will always have an x-value of 0. This allows it to lie on the y-axis, hence the name. Our y-value of the coordinates is given with the b value of the equation. Therefore, by simply looking at the end of the equation, we know our first point.

A sphere has a volume of approximately 24,416.64 cubic inches (using 3.14 for ).
The diameter of the sphere is ___ inches.
Answer:
diameter = 36 in.

12x + 5 = 89
12x = 84
x = 7.
[ii] 9x + 7 = 1/2(198 + 7x - 8)
18x + 14 = 198 + 7x - 8
11x = 176
x = 16.
[iii] 15x - 8 = 1/2(16x +1 + 5x + 19)
30x16 21x + 20
9x = 36
x = 4.
[iv] 20x - 4 = 360 - 2 × 72
20x = 220
x=220/20=11°
[v] 13x - 1 = 2(6x + 11)
13x - 1 = 12x + 22
x = 23.
[vi] 46 = 1/2(21x-5-x-23)
20x2892
20x = 120
x = 6.
[vii] 6x - 21 = 1/2(13x - 3-3x - 11)
12x - 4210x - 14
2x = 28
x = 14.
[viii] 2x + 1 = 1/2(9x − 14 − 4x + 7)
4x + 2 = 5x - 7
x = 9.
[ix] 9x - 4 = 180 - 76
9x - 4 = 104
9x = 108
x = 12.
convert each of these fractions so that they share the lowest common denominator 3/4 4/5 and 5/6
The lowest common denominator is 120.
Convert 3/4: 90/120
Convert 4/5: 96/120
Convert 5/6: 100/120

If you read 340 pages in 45 minutes how many pages do read in 1 minute
Answer:
7 5/9
Step-by-step explanation:
340/45 = 7 5/9
Answer:
7.6 pages
Step-by-step explanation:
Okie, so this is a standard unit rate problem, so what you're going to do is divide the number of whatever, in this case, pages, by the time, so:
340 ÷ 45 = 7.6 (rounded)
So you read 7.5 pages per minute
(which is pretty impressive if it's a chapter book)

A cylinder has a radius of 4 inches and a height of 5 inches. If the radius of the cylinder is tripled and the height remains the same to create a new cylinder, what will be the difference in the surface areas of the two cylinders? Answer in terms of Pi.
Answer:
336π in²Step-by-step explanation:
Cylinder 1
r₁= 4 inh = 5 inCylinder 2
r₂ = 3*4 = 12 inh = 5 inSurface area of cylinders:
S = 2πr(r + h)S₁ = 2π*4*(4 + 5) = 72π in²S₂ = 2π*12*(12 + 5) = 408π in²The difference is:
S₂ - S₁ = 408π - 72π = 336π in²A cylinder has a radius of 4 inches and a height of 5 inches. If the radius of the cylinder is tripled and the height remains the same to create a new cylinder, what will be the difference in the surface areas of the two cylinders ? Answer in terms of Pi.
Answer:-Given:-A cylinder has a radius of 4 inches and a height of 5 inches.
To Find:-If the radius of the cylinder is tripled and the height remains the same to create a new cylinder, what will be the difference in the surface areas of the two cylinders ?
Solution:-Let in case of 1st cylinder,[tex] \bullet [/tex] Radius [tex] (r_1) [/tex] is 4 inches
[tex] \bullet [/tex] Height is 5 inches
And in case of 2nd cylinder,[tex] \bullet [/tex] Radius [tex] (r_2) [/tex] is 3 × 4 = 12 inches [as in the question it is given that the radius of the cylinder is tripled]
[tex] \bullet [/tex] Height is 5 inches
Now,
Surface area [tex] (s_1) [/tex] of 1st cylinder
is 2πr(r + h) = 2π × 4(4 + 5)
= 8π(9)
= 72π sq inches
Surface area [tex] (s_2) [/tex] of 2nd cylinder
is 2πr(r + h) = 2π × 12(12 + 5)
= 24π(17)
= 408π sq inches
[tex] \therefore [/tex] The difference in the surface areas of the two cylinders is = [tex] (s_2 \: - \: s_1) [/tex] = (408π - 72π) = 336π sq inches
The difference in the surface areas of the two cylinders is 336π sq inches. [Answer]Elena notices that when she spends less time on social media the night before a quiz she gets a higher test score.

The equation that represents the total score points will be y = - (4/34)x + 49.58.
What is the equation of a line passing through two points?Let the equation of the line pass through (x₁, y₁) and (x₂, y₂). Then the equation of the line is given as,
[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)\\[/tex]
The two points are (107, 37) and (73, 41).
Let 'x' be the number of minutes and 'y' be the total score. Then the equation is given as,
(y - 41) = [(41 - 37) / (73 - 107)](x - 73)
y - 41 = - (4/34)(x - 73)
y = - (4/34)x + 49.58
The equation that represents the total score points will be y = - (4/34)x + 49.58.

Actually Welcome to the concept of areas,
we know that, area of rectangle = length * width,
here, length = x-2 and width = x-1
hence, area = (x-2) (x-1)
==> area = x^2 -x -2x +2
==> Area = x^2 - 3x + 2
hence the Option D.) is correct
