Answer:

166 2/13 deg

Step-by-step explanation:

The sum of the measures of the interior angles of a convex polygon of n sides is 180(n - 2).

A hexagon has 6 sides, so n = 6.

sum of measures of angles = 180(n - 2) = 180(6 - 2) = 180(4) = 720

4x + 5x + 6x + 7x + 8x + 9x = 720

39x = 720

x = 720/39

x = 240/13

The largest angle has measure 9x.

9x = 9 * 240/13 = 2160/13

2160/13 = 166 2/13

Answer: 166 2/13 deg

Please help please please

Answer: I believe his earnings would be 187$ once he teaches 7 classes.


Step-by-step explanation:

$187-$68=$111

17 x ? = 119

(take the 17$ which is the amount of money he'll earn each class and divide by 111. as seen below:

$111/17$=$6.5 (round to $7)

(you then plug in the 17 for 7 x ? = 119)

7x17=119

now you have to add the 68$ that he will get per month.

119+68=187

then you get 187$ which he had spent on the certificate

He collected a total of 225 . If ​68% of the stamps he collected were​ foreign, how many other stamps did he​ collect?
MissTica

Answer:

72 stamps

Step-by-step explanation:

First, we're looking to find the number of stamps that AREN'T foreign, so we have to subtract 68% from 100%.

  • 100% - 68%
  • 32%

Now, we know that 32% of the stamps are NOT foreign. So, next, we:

  1. Multiply 32 by 225.
  2. Divide the product of 32 and 225 by 100
  • 32*225
  • 7200
  • 7200/100
  • 72

Therefore, the answer is 72 stamps.
