The length of each side of a square is 6 feet more than the length of a side of a regular Octagon. The perimeter of the square i
goldfiish [28.3K]

9514 1404 393

Answer:

  • square: 12 ft sides
  • octagon: 6 ft sides

Step-by-step explanation:

This problem can be worked in your head.

If the perimeters of the square and regular octagon are the same, the side length of the 4-sided square must be the same as the length of 2 sides of the 8-sided octagon. Since the side of the square is 6 ft more than the side of the octagon, each side of the octagon must be 6 ft, and each side of the square must be 12 ft.

__

We can let s represent the side length of the octagon. Then we have ...

  8s = perimeter of octagon

  4(s +6) = perimeter of square

These are equal, so ...

  4(s +6) = 8s

  s +6 = 2s . . . . . . divide by 4

  6 = s . . . . . . . . . . subtract s

The octagon has 6-ft sides; the square has 12-ft sides.

Max earned a 85% on his test. if there were 40 questions on the test how many did he get correct?
wel
Max would have had to have gotten 34 out of 40 questions correct. Here's why:

\frac{x}{40} =  \frac{85}{100} 

(40)(85) = (x)(100)



3400 = 100x

 \frac{3400}{100} = x


34 =x

Suppose that y varies inversely as x, and x=9 when y=15. Find the value for k and write the function. Group of answer choices La
Radda [10]

Answer:

see explanation

Step-by-step explanation:

Given that y varies inversely as x then the equation relating them is

y = \frac{k}{x} ← k is the constant of variation

To find k use the condition that x = 9 when y = 15

15 = \frac{k}{9} ( multiply both sides by 9 )

k = 135

y = \frac{135}{x} ← equation of variation

Somebody answer !!!!!
Rainbow [258]

Answer:

D)

Step-by-step explanation:

First we have to subtract 5 from both sides

\sqrt{x-6} +5=12\\\\\sqrt{x-6}+5-5=12-5\\\\\sqrt{x-6}=7

Now, square both sides

(\sqrt{x-6})^{2}=7^{2}

x - 6 = 49

Now, add 6 to both sides

x - 6 +6 = 49 + 6

x = 55
