Answers

Answer 1

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:

your answer will be 25 .....ok

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

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.

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?​

Answers

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

can someone help with the two triangle questions (will mark brainliest!!)

Answers

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
