All angles add up to 360 degrees.
Diagonals are always congruent.
Answer:
all angles add up to 360 degrees
Step-by-step explanation:
using substitution
x+3y=3
3y-2x=12
Step-by-step explanation:
Given :-
x + 3y = 3 3y - 2x = 12And we need to solve the equation using Substituting method . So on taking the first equation ,
[tex]\rm\implies x + 3y = 3 \\\\\rm\implies x = 3 - 3y [/tex]
Put this value in (ii) :-
[tex]\rm\implies 3y - 2x = 12 \\\\\rm\implies 3y - 2(3-3y)=12\\\\\rm\implies 3y -6-6y = 12 \\\\\rm\implies -3y = 18 \\\\\rm\implies y = -6 [/tex]
Put this Value in (I) :-
[tex]\\\\\rm\implies x = 3-3*-6 \\\\\rm\implies x = 3+18 \\\\\rm\implies x = 21 [/tex]
Hence the Value of x is 21 and y is (-6) .
Answer:
x = -3
y = 2
Step-by-step explanation:
Ok this is a long one but bear with me lol, i promise i will make it easy to understand, performing one step at a time.
So we are given 2 equations right? We can take any of these one equation and isolate any one variable, either x or y, I will take the first equation and isolate x from it cuz it's the easiest way;
=> x + 3y = 3
=> x = -3y + 3 (Let's pretend this is not an equation for x but a "value")
Now that we have the x isolated from first equation, we can substitute x "value" in for the x in second equation. To solve for y;
=> 3y - 2 (-3y + 3) = 12
=> 3y + 6y - 6 = 12
=> 9y - 6 = 12
=> 9y = 12 + 6
=> 9y = 18
=> y = 18/9
=> y = 2
At this point we are almost done with the question! So since we got a real value for one of our variable (which in this case is y-value), we can substitute that in any of the given equation, We can also use the equation where in we isolated "x", so I'll use that cuz it's gonna require less steps, to find the real x-value:
=> The equation we found out up there is: x = -3y + 3
=> Now just simply substitute the y-value we figured in the equation above:
=> x = -3y + 3
=> x = -3(2) + 3
=> x = -6 + 3
=> x = -3
Ayee we did it lol so the final answer would be:
x = -3
y = 2
I really hope this made sense, and that it helps!

Mr.Q's class is having a giveaway where his students can receive 100 classroom credits. He will pull names out of a hat and select two winners. Once a student wins, they are not eligible to win a second time. If there are 40 total people in the class, including you and your best friend.
What is the probability that both you and your best friend get the 100 classroom credits?
PLEASE SHOW WORK!!
Answer:
1/1560
Step-by-step explanation:
The chance of you winning is 1/40, since there are 40 students and you are one of those students. Since, you cannot win again once you win once, you are eliminated. This leaves us with 39 people left. The chances of your friend being chosen out of the 39 people left is 1/39. Now you must multiply 1/40 and 1/39. After multiplying, you get 1/1560.
Find the surface area of the figure below.
Answer:
261 cm²
Step-by-step explanation:
To find the surface area of a square pyramid, you must first recognize all of the shapes.
There are four triangles and one square.
To find the area of a square, multiply the side by itself twice.To find the area of a triangle, multiply the base and the height, then multiply the product by 1/2.The triangles have a base of 9 and a height of 10.
[tex]9*10=90[/tex]
Multiply the product by 1/2.
[tex]90*1/2 = 45[/tex]
There are four triangles.
[tex]45*4=180[/tex]
The area of all three triangles is 180 centimeters; the area of a single triangle is 45 centimeters.
There square has sides of 9 centimeters.
[tex]9*9=81[/tex]
The area of the square is 81 centimeters.
Lastly, we add the areas of the shapes.
[tex]45+45+45+45+81 = 261.[/tex]
Therefore, the surface area of this square prism is 261 cm².
You can use this layout to find the surface area of a square pyramid.

An account with an initial balance of $5000 earns 5% interest for 3.5 years.
Answer:
The investor will earn $875 over the course of 3.5 years.
Step-by-step explanation:
Sounds like simple interest (not compound interest).
The appropriate formula is i = prt, which here is
i = $5000(0.05)(3.5) = $875
The investor will earn $875 over the course of 3.5 years.
help how do i solve for this ?
Answer:
Solution:
Given,
Radius(r) = 11 ft
C = ?
Now,
[tex]c = 2\pi \: r[/tex]
C = 2 × 3.14 × 11
= 70 cm
again,
C = 360°
angle = 315°
So,
C = 70 cm
or, 360° = 70 cm
or 1° = 70/360°
or 1° = 7/36
again ,
area = 7/36 × 315°
= 61.25 cm

En la tienda de electrónica Se vende un televisor en 15480 pesos pero tendrá un descuento del 35% de su precio entonces cuánto costará el televisor y con el descuento
Respuesta:
Monto descontado = 5,418pesos
Nuevo precio de la televisión = 10.062 pesos
Explicación paso a paso:
Costo inicial de televisión = 15,480 pesos
Porcentaje de descuento = 35%
Cantidad descontada = 35% de 15,480
Cantidad descontada = 0.35 * 15,480
Monto descontado = 5,418pesos
Nuevo precio de la televisión = 15.480 - 5.418
Nuevo precio de la televisión = 10.062 pesos
which is equivalent to ?
Answer:
A
Step-by-step explanation:
Multiply [tex]\frac{x}{\sqrt{2} }[/tex] by [tex]\frac{\sqrt{2} }{\sqrt{2} }[/tex] and you would get [tex]\frac{x\sqrt{2} }{2}[/tex] because [tex](\sqrt{2 } )^{2} =2[/tex]

Step-by-step explanation:
Shannon went to an auto repair shop and paid $339.50, which included parts that cost $112 and 3.5 hours of labor. Joni went to an auto repair shop and paid $455, which included parts that cost $310 and 2.5 hours of labor. Which correctly compares the cost of the labor?
Answer:
Option A, Shannon paid $ 7 per hour to labor than Joni
Step-by-step explanation:
Total amount paid by Shannon = $339.50
Total cost of 3.5 hours of labor paid by Shannon =($339.50- $112)
Total cost of 3.5 hours of labor paid by Shannon = $227.5/3.5
Total cost of 1 hours of labor paid by Shannon $65 per hour
Total amount paid by Joni = $455
Total cost of 2.5 hours of labor paid by Joni = $455- $$310
Total cost of 1 hours of labor paid by Joni = $145/2.5
Total cost of 1 hours of labor paid by Joni = $ 58
Hence, Shannon paid $ 7 per hour to labor than Joni
Option A is correct

A triangle has angle measurements of 53°, 37°, and 90°. What kind of triangle is it?
Answer and Step-by-step explanation:
This triangle is a right triangle.
- Acute angles are angles that have a degree that is less than 90 degrees.
- Obtuse angles are angles that have a degree that is more than 90 degrees.
- Right angles are angles that are 90 degrees.
It has 1 angle that is 90 degrees, so it is a right triangle.
