What are congruent triangles?Two triangles are said to be congruent if their corresponding sides and angles are equal.
Given,
side LM ≅ side OP
side MN ≅ side PQ
∠M = ∠P
As per the shown figure, we have two triangles consist:
LM = OP (side)
∠M = ∠P ( angle)
MN = PQ (side)
According to Side-Angle-Side criterion, two triangles are congruent if the two sides and the included angle of one triangle are equal to the corresponding sides and the included angle of the other triangle.
Thus, ΔLMN congruent to ΔPQO.

Answers
Hey there! I'm happy to help!
In a 30-60-90 triangle, the shorter leg is always 1/2 of the hypotenuse. This can be proven using many different methods and there a lot of interesting videos out there about it. This is useful in geometry, trigonometry, and more.
So, if we know that the shortest leg is 12, we can make the following equation. We will have h represent the hypotenuse.
1/2h=12
Now, we simply divide both sides by 1/2 (which is the same as multiplying both sides by two.
h=24
Therefore, the hypotenuse is C) 24.

Robert sketches two rectangular prisms, A and B. Prism A's side lengths are 5 centimeters, 6 centimeters, and 7 centimeters. Prism B's side lengths were twice those of prism A's: 10 centimeters, 12 centimeters, and 14 centimeters. Robert says the surface area of prism B is twice the surface area of prism A. Is he correct? If he is not, how many times as great as prism A's surface area is prism B's surface area?
Robert is 1.___; the Surface area of A is ____ square centimeters. The Surface area of B is _____square centimeters. B's surface area is ____ times as great as A's.
Answers
Answer:
4 times greater
Step-by-step explanation:
Prism A
SA = 2 (lw+wh+lh) where l is length w is width and h is height
SA = 2 ( 5*6+ 6*7+ 5*7)
SA = 2(30+42+35)
SA = 2(107)
SA =214
Prism B
SA = 2 (lw+wh+lh) where l is length w is width and h is height
SA = 2 ( 10*12+ 12*14+ 10*14)
SA = 2(120+168+140)
SA = 2(428)
SA =856
Robert is not correct
856/214 =4
Prism B is 4 times greater
Answer:
Prism B's surface area is 4 times Prism A's.
The surface area of Prism A is 214 square centimeters.
The surface area of Prism B is 856 square centimeters.
Step-by-step explanation:
To find the surface area of a rectangular prism, use this formula:
[tex]A=2(wl+hl+hw)[/tex]
Where w is the width, h is the height, and l is the length.
Substitute the values given for Prism A and Prism B into the formula to find each prism's surface area:
Prism A:
[tex]A=2(5 * 6+6 * 7+5 * 7)\\A = 2 (30 + 42 + 35)\\A = 214[/tex]
Prism B:
[tex]A=2(10*12+12*14+14*10)\\A = 2 (120 + 168 + 140)\\A = 856[/tex]
Prism B's surface area is 4 times Prism A's.
The surface area of Prism A is 214 square centimeters.
The surface area of Prism B is 856 square centimeters.
what is the inverse function of f(x)= x/x-2?
Answers
Answer:
[tex]f^{-1}(x)=\frac{2x}{x-1}[/tex]
Step-by-step explanation:
Start by replacing f(x) by the variable "y" and solving for x in the equation:
[tex]f(x)=\frac{x}{x-2} \\y=\frac{x}{x-2}\\(x-2)\,y=x\\xy-2y=x\\xy-x=2y\\x(y-1)=2y\\x=\frac{2y}{y-1}[/tex]
Now do the final replacement using the inverse function notation, and replacing "y" with "x":
[tex]x=\frac{2y}{y-1} \\f^{-1}(x)=\frac{2x}{x-1}[/tex]
The inverse of the function f(x)= x/x-2 is; f-¹(x) = 2x/(x-1)
Since the function can be rewritten as;
y = x/x-2By making x the subject of the function;
yx - 2y = x x (y -1) = 2yx = 2y/(y-1)By swapping x and y; we then have;
y = 2x/(x-1)The inverse function is therefore; f-¹(x) = 2x/(x-1)

What is Linear Association?A straight-line link between two variables is referred to statistically as a linear relationship (or linear association).
If one variable increases roughly at the same rate as the other variables change by one unit, the relationship is said to be linear.
The scatter plot below shows the average number of customers who visit a food truck per day, depending on the number of days the food truck stays in the same location.
As, If the slope is positive, then there is a positive linear relationship, i.e., as one increases, the other increases.
If the slope is negative, then there is a negative linear relationship, i.e., as one increases the other variable decreases.
Here, the slope seems to be positive.
Thus, this is positive linear Association.

We can find the horizontal transformation by:
g(x) = f(x - h)
Where h is the number of units we shift (to the right).

Answers
Answer: n/2, n/2+1
Step-by-step explanation:
Consecutive numbers are always 1 more than the previous (n, n+1, n+2, n+...), and their sums are (like) n+n+1 or 2n+1 (n is the first number).
So in this situation (x is the first number);
n+1=x+x+1
n=x+x, n=2x
n/2=x
Meaning that the first number is n/2, and the second (n/2)+1 or just n/2+1.

What is the surface area of this solid?
Answers
Answer:
SA. = 62.8 +87.92= 150.72
Step-by-step explanation:
surface area of cone without base = pi*r*s = 3.14 * 2* 10 = 62.8
Surface area of cylinder without base = 2*pi*r*h + pi*r*r
= 2* 3.14 * 2 * 6 + 3.14*2*2
= 75.36 + 12.56 = 87.92
SA. = 62.8 +87.92= 150.72
The required surface area of the solid is 150.72.
Given
slant length of cone = 10
length of cylinder = 6
Common radius = 2
What is surface area?
Surface area is defined as the area of the surface that are uncovered.
Surface area of cone = π x r xs
= 3.14 x 2 x 10
= 62.82
Surface area of cylinder = 2 x π x r x h + π x r²
= 2 x 3.14 x 2 x 6 + 3.14 x 2 x 2
= 87.9
The required surface area of solid= surface area of cone + surface area of cylinder
= 62.80 + 87.9
= 150.72
Thus, the required surface area of the solid is 150.72.

Step-by-step explanation:
The 262,400 solar cells cover around 27,000 square feet (2,500 m2) of space. 240 kilowatts of electricity can be generated from these solar arrays.which is an acre of solar panels and enough to power 10 average- sized homes with 110 kilowatts of power. The ISS orbits between 370 and 460 kilometers (230–286 miles) above Earth's surface.

The total area of the top surface of all 16 solar panels should be 153,600 feet because the total area of one solar panel is 9,600 feet so since i need the total area of 16 i just multiply the total area of one solar panel with the amount of solar panels that i was given.

Answer:
1) y=1/2x+12
2)y=-2x+13
3) Parallel lines have same slope, different y intercept and perpendicular lines have opposite reciprocal slopes.
Step-by-step explanation:
Answer:
Below in bold.
Step-by-step explanation:
Y = mx + b is the slope-intercept form of a straight line where m = the slope of the line and b is the y-intercept.
Parallel lines have the same slope so the equation of a line parallel to
y = 1/2x + 13 could be y =1/2x + 10 as they have the same slope of 1/2.
Equations which are perpendicular:
If the slope of one is m then the slope of the perpendicular equation is -1/m.
So for y = 1/2 x + 13 an equation perpendicular could be y= -(1 / 1/2) + 13
= y = -2x + 13
