Inscribed circle of a triangle is the largest circle, contained in the triangle.
Steps to construct the inscribed circle of a triangle-
Step 1-Bisect one of the angle of the triangle.Step 2-Now bisect the another angle of the triangle.Step 3-The crossing point of both the angle bisects is the in center of the triangle and center of the required circle.Step 4- Draw a perpendicular from this center to one of the side of the triangle.Step 5-Now draw a circle using the compass with the in center as a center of the and radius equal to the perpendicular from the in center to one of the side.Thus to construct the inscribed circle of a triangle the in-center is required. the option 3 is the correct option.

What is the mass of 2.5 moles of carbon dioxide?
Answer:
110 grams
Step-by-step explanation:
CO2 molecule is made up of Carbon (atomic mass =12) and oxygen (atomic mass=16).
So first finding the mass of 1 molecule of CO2 which is equals to
= mass of 1 carbon atom + masses of 2 oxygen atom, we get
= 12+(16*2)= 12+32= 44 a.m.u.
Now 1 molecule of CO2 has mass 44 amu so mass of 1 mole CO2 will be 44 grams.( 1 a.m.u.=1.6729*10^-33 grams. 1 mole = 6.022*10^23, so 44 a.m.u.=73.6076*10^-33 grams approx. For one mole CO2, 73.6076*10^-33*6.022*10^23 which is approximately equals to 44 grams. )
1 mole CO2= 44grams, so 2.5 moles = 44*2.5= 110 grams
So our answer is 110 grams.

Scott makes and sells bracelets. He spends $28 on supplies, and he sells
each bracelet for $6. Write an expression that represents his profit for
selling b bracelets.
Hi there,
Recall how each bracelet sells for 6 dollars.
Hence, the expression for selling b bracelets is 6b, where b is the number of bracelets sold for the price of 6 dollars.
Profit is the actual amount of money that is earned after you subtract expenses from the total sales.
For instance, if you make $100 from selling items, and you spent $25 on your supplies, then your profit is [tex]100-25=75[/tex].
In this case, you need to subtract the $28 spent on supplies from the amount of money that you have made, which is the expression 6b.
Hence, the expression for the profit is: [tex]6b-28[/tex]

Answer:
for #1 it's 1, 4, 5, 6
for #2 it's both lines have the same slope
for #3 it's both lines have a different y-intercept
Step-by-step explanation:
#1 explanation: all of them have the y-intercept of -8
ex. y = 3x (- 8) y = 5x (-8) y = 2x (-8) y = (1/3)x (-8)
#2 explanation: both have a slope of (1/4)
#3 explanation: y = (1/4)x there is not y-intercept that we know of and y = (1/4)x - 5 the y-intercept is at -5 therefore the y-intercepts are different

How much solutions does this equation have?
2x+y=3
2y=-4x+6
pls answer,, show ur work, have a great day :)) !!
Answer:
All solutions or infinite.
Step-by-step explanation:
Turn 2y = -4x + 6 into standard form - divide by 2
Y = -2x + 3
2x + y = 3
Substitute the y equation in for y.
2x - 2x + 3 = 3
The x variables cancel out.
3 = 3
Which is true so it means all solutions.

Answer:
14) 9.2 15) 12.9
Step-by-step explanation:
14) cos(52) = x/15
x = 15cos(52)
x = 9.2349
x = 9.2
15) cos(22) = 12/x
x = 12/cos(22)
x = 12.9424
x = 12.9

Answer:
[tex]x=4[/tex], [tex]y=61[/tex]
Step-by-step explanation:
Since the triangles are congruent, we already know that they have the same angles and sides.
We can solve for the missing side with this equation:
[tex]51=12x+3[/tex]
subtract [tex]3[/tex] from both sides
[tex]48=12x[/tex]
divide both sides by [tex]12[/tex]
[tex]x = 4[/tex]
Due to the Angle Theorems we already know [tex]2[/tex] of the angles on the triangle:
[tex]63[/tex] and [tex]56[/tex]
We can solve for the missing angle with this equation:
[tex]A+B+C=180[/tex]
[tex]63+56+y=180[/tex]
[tex]119+y=180[/tex]
subtract [tex]119[/tex] from both sides
[tex]y=61[/tex]

gonzalo nacio el 18 de sptiembre de 1945 si bertha nacio cuatro decadas y un lustro cual es la fecha de nacimiento de bertha
Answer: Bertha nació el 18 de septiembre de 1990.
Step-by-step explanation:
Gonzalo nació el 18 de septiembre de 1945.
Bertha nació cuatro décadas y un lustro después.
Una década son 10 años
Un lustro son 5 años
Entonces 4 décadas y un lustro son:
4*10 años + 5 años = 45 años
Esto significa que Bertha nació 45 años después que Gonzalo.
Entonces si Gonzalo nació en 1945, Bertha nació en el año:
1945 + 45 = 1990
Bertha nació el 18 de septiembre de 1990.
La fecha de nacimiento de Bertha es el 18 de septiembre de 1990.
How many years does a decade have?A decade is composed of 10 years. So, if there are 'x' decades, then that means there are going to be [tex]10 \times x[/tex] years in it.
For this case, we are given that:
Date of birth of Gonzelo is 18th of Sept. 1945
Bertha born after 4 decades and 5 years of Gonzelo's birth.
4 decades = 4 times 10 = 40 years
Thus, 4 decades + 5 years = 40 + 5 = 45 years.
45 years after 1945 uis 1945 + 45 = 1990
Thus, date of birth of Bertha is 18th Sept. 1990
