Answer:
900° and 1260°
Step-by-step explanation:
The sum of the interior angles of a polygon is calculated as
sum = 180° (n - 2) ← n is the number of sides
(2)
Here n = 7 , then
sum = 180° × 5 = 900°
(3)
Here n = 9 , then
sum = 180° × 7 = 1260°

Answer: Number 1 is c=89 ft
Number 2 is b=3 cm
Step-by-step explanation: a²+b²=c²
For number 1, 39 ft is a and 80 ft is b so
39²+80²=c² so 39² is 39x39=1521 and 80² is 80x80=6400 so 6400+1521=7921
7921=c² and the square root of 7921 is 89 so c=89 ft
For number 2, a=1.6 cm and c=3.4 cm so 3.4²-1.6²=b²
3.4² so 3.4x3.4 which is 11.56
1.6² so 1.6x1.6 which is 2.56
11.56-2.56=c² and 11.56-2.56=9
Square root of 9 is 3 so b=3
So number 2 answer is b=3 cm

Answer:
x = 25
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 3 when x = 15
3 = 15k ( divide both sides by 15 )
[tex]\frac{3}{15}[/tex] = k, that is k = [tex]\frac{1}{5}[/tex]
y = [tex]\frac{1}{5}[/tex] x ← equation of variation
When y = 5 , then
5 = [tex]\frac{1}{5}[/tex]x ( multiply both sides by 5 to clear the fraction )
25 = x
find an equation for each line

john is twice as old as his son. his son is 5 years older than his sister . in five years to come John will be 3 times as old as his daughter. how old is his son now?
Answer:
5
Step-by-step explanation:
Terrible wording on the question as the "father" is 15 the "son" is 10 and the sister is 0 or just born
J = john
S = son
X = sister
J = 2s
S = 5 + X
3(x+5) = J + 5
J = 2(5+x) = 2x + 10
3x+15 = 2x +10 + 5
x = 0

Total cost of pay for the lunch will be $96.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The cost of lunch = $75
Sales tax = 8%
Tip = 20%
Now,
The cost on sales tax = 8% of $75
= 8/100 x 75
= $6
Thus, The cost on sales tax = $6
And, The cost for tip = 20% of $75
= 20/100 x 75
= $15
Thus, The cost for tip = $15
So, Total cost to pay for lunch = $75 + $6 + $15
= $96
Thus, Total cost of pay for the lunch will be $96.
