If a regular polygon has exterior angles that measure 40 each how many sides tdoes the polygon have

1 answer:

7 0

Every polygon has a sum of exterior angles equal to 360° (This doesn’t apply to interior angles, though.)

If you have exterior angles that are 40° each, then you can see how many times it goes into 360° to find your number of sides.

360° / 40° = 9 sides

Hope this helps!

Solve the equation with the replacement set {–59, –9, 9, 59}

ivann1987 [24]

The equation can be resolve to two equations:

... 34-x = 25 . . . . . solution x = 34 - 25 = 9

... 34-x = -25 . . . . solution x = 34 - (-25) = 59

Your solution is 9, 59.

Noa was walking in the forest and measured the circumference of two trees that he found. The first tree measured 37 5/8 inches a

rodikova [14]

Answer:

Step 4: 44 32/24 - 37 15/24= 8 17/24

Here we can finally find out the mistake done by Noa. The result is 7 17/24 and not 8 17/24.

Step-by-step explanation:

1. Let's review carefully all the steps taken by Noa to calculate the difference of the circumferences of the two trees.

Circumference Tree 1 = 37 5/8 inches around

Circumference Tree 2 = 45 1/3 inches around

Step 1: 45 1/3- 37 5/8

The measures are correct, no issues copying them.

Step 2: 45 8/24 - 37 15/24

Noa looked for common denominators

1/3 * 8/8 = 8 /24 is correct; 5/8 * 3/3 = 15/24 is also correct.

Step 3: 44 32/24 - 37 15/24

Noa looked for making the fraction part higher on the left side:

45 8/24 = 44 32/24 is correct because 24/24 = 1

Step 4: 44 32/24 - 37 15/24= 8 17/24

Here we can finally find out the mistake done by Noa. The result is 7 17/24 and not 8 17/24.

4a + 6b=10 2a - 4b =12 What is 12a?

Maksim231197 [3]

Hi!

4a + 6b = 10
2a - 4b = 12

First make both a terms equal
2a · 2 - 4b · 2 = 12 · 2
4a - 8b = 24

Subtract both expressions to cancel out the a term.
4a + 6b = 10
-4a - 8b = 24
14b = -14
b = -1

Now put the value in one of the equations and solve
2a - 4 · -1 = 12
2a + 4 = 12
2a = 8
a = 4

Since a = 4, 12a = 48.

The answer is 48

Hope this helps! :)
