How to construct the inscribed circle of a triangle?
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.

Lin's father is paying for a $20 meal. He has a 15%-off coupon for the meal. After the discount, a 7% sales tax is applied. What does Lin's father pay for the meal? Explain or show your reasoning.
Answer:
$18.19
Step-by-step explanation:
20 decrease 15% =
20 × (1 - 15%) = 20 × (1 - 0.15) = 17
17 increase 7% =
17 × (1 + 7%) = 17 × (1 + 0.07) = 18.19

A dog weighs 60 N on planet Earth. On the moon, he would weigh about
176 (one-sixth) of what he does on Earth. How much does the dog weigh on
the moon?
Answer:
16.09N
Step-by-step explanation:
Answer:
[tex]\boxed{\purple{\textsf{The weight of the dog on moon is \textbf{10 Newtons. }}}}[/tex]
Step-by-step explanation:
Given that the weight of the dog on the earth is 60N . We need to find the weight of dog on the moon. So we know that the weight of an object is one sixth the weight of an object on the moon. In other words the acceleration due to gravity is one sixth on the moon that of earth. We can use a formula as ,
[tex]\qquad\boxed{\boxed{\sf Weight_{(On \ moon )}= \dfrac{1}{6}\times Weight_{(On \ earth )}}}[/tex]
On substituting the respective values :-
[tex]\sf\implies Weight_{(On \ moon )} = \dfrac{1}{6}\times Weight_{(On \ earth )} \\\\\sf\implies Weight_{(On \ moon )} =\dfrac{1}{6}\times 60 N \\\\\sf\implies\boxed{\pink{\frak{ Weight_{(On \ moon )}= 10 \ Newtons }}}[/tex]

Write a function in terms of t that represents the situation.
An item costs $4.50, and its price increases by 3.5%
each year.
Answer:
4.5(1.035)^t
Step-by-step explanation:
An inrease of 3.5% means that each year's total is 103.5% of the year before, right?
Year 1 = 4.5(1.035) = 4.66
Year 2 = 4.66(1.035) = 4.82
etc.
So, year 2 is 4.5(1.035)(1.035) = 4.82
Multiplying something by itself can be written with an exponent instead, so 2 years is...
4.5(1.035)2
Since the number of years is the variable (let's call it t)...

Write an expression to show the final cost, in dollars, of x games when using the coupon.
Answer:
5x + 2.50 - 0.2
Step-by-step explanation:
The 5x is because each game (x) costs 5 dollars. You add 2.50 because that is how much extra you have to pay for the bowling shoes. To compensate for the -20% off of the total price, I added the -0.2 (20% as a decimal).
Note:
I am 100% sure about the "5x + 2.50 -" part. The 0.2 part not so much.
I hope this is correct and helps though!

Answer:
[tex] \frac{1}{81} [/tex]
Step-by-step explanation:
express that with a positive exponent using this:
[tex] {a}^{ - n} \frac{1}{ {a}^{n} } [/tex]
so ..
[tex] {9}^{ - 2} = \frac{1}{ {9}^{2} } [/tex]
now you have to evaluate the exponent/ power
so..
[tex] \frac{1}{ {9}^{2} } = \frac{1}{81} [/tex]
why 81 ?
because the exponent of 9 is 2 so you have to multiple 9 by itself so
9x9=81
so the answer is
[tex] \frac{1}{ {81}^{} } [/tex]
sorry for the bad english hehe
select the equivalent expression. (a^-2 • 8^7)^2
a. 8^9
b. (8a)^10
c. a^-4 • 8^14
Answer:
c.
Step-by-step explanation:
The equivalent expression of [tex](a^{-2}.8^{7} )^{2}[/tex] is [tex]a^{-4} .8^{14}[/tex].
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:
Constant: A constant is a fixed numerical value.
Variable: A variable is a symbol that doesn't have a fixed value.
Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.
Coefficient: A coefficient is a number that is multiplied by a variable in an expression.
Given expression
[tex](a^{-2}.8^{7} )^{2}[/tex]
Using formula [tex]a^{-m} =\frac{1}{a^{m} }[/tex]
= [tex](\frac{8^{7} }{a^{2} } )^{2}[/tex]
= [tex]\frac{(8^{7}) ^{2} }{(a^{2}) ^{2}}[/tex]
Using [tex](a^{m} )^{n} =a^{m \times n}[/tex]
= [tex]\frac{8^{14} }{a^{4} }[/tex]
= [tex]a^{-4} .8^{14}[/tex]
Option C is correct.
The equivalent expression of [tex](a^{-2}.8^{7} )^{2}[/tex] is [tex]a^{-4} .8^{14}[/tex].
