How to i find the missing 2 angles

Answers

Answer:

therefore, x is 71 degrees

Step-by-step explanation:

we know that the exterior angle is 142 degrees.

we also know that we have to find x, which is labeled two times as an interior triangle (in the same triangle), so they must be the same degree.

there are different ways to solve this but the easiest way is this:

exterior angle = opposite interior angle 1 + opposite interior angle 2

142 degrees = x + x

142 degrees = 2x

142/2 = x

x = 71

therefore, x is 71 degrees

The job that would give you more is the one where you double the penny everyday. Although it seems small at first but slowly slowly you start making a lot more money.

To calculate how much you would make in 30 days by doubling the penny, you just double the amount every day until you get to 30:
$.01 - First day
$.02
$.04
$.08
$.16 - Fifth day
$.32
$.64
$1.28
$2.56 - Ninth day
....
$5,368,709.12 - 30th day

If you add it all up, the sum you would get is $10,737,418.23.

That is 11 times more than the first option! :)

Table:
Days      Money
Day 1     $.01
Day 2     $.02
Day 3     $.04
Day 4     $.08
Day 5     $.16
Day 6     $.32
Day 7     $.64
Day 8     $1.28
Day 9     $2.56
Day 10   $5.12
Day 11   $10.24
Day 12   $20.48
Day 13   $40.96
Day 14   $81.92
Day 15   $163.84
Day 16   $327.68
Day 17   $655.36
Day 18   $1,310.72
Day 19   $2,621.44
Day 20   $5,242.88
Day 21   $10,485.76
Day 22   $20,971.52
Day 23   $41,943.04
Day 24   $83,886.08
Day 25   $167,772.16
Day 26   $335,544.32
Day 27   $671,088.64
Day 28   $1,342,177.28
Day 29   $2,684,354.56
Day 30   $5,368,709.12

And as mentioned above, the total sum is $10,737,418.23

Number of periods would be is 30 days. Or 1 month.

The population of bacteria in a petri dish doubles every 24 h. The population of the bacteria is initially 500 organisms.How long will it take for the population of the bacteria to reach 800?

Round your answer to the nearest tenth of an hour.

Answers

Answer:

16.3h

Step-by-step explanation:

population 2x in 24 h

going from 500 to 800 is less than double so ans is <24h

solving t:  2^(t/24)=800/500

t/24=ln(8/5)/ln2

t=24*ln(8/5)/ln2

=16.3

What is the value of k?

Answers

Answer:

Step-by-step explanation:

recall that the inside angles of a triangle add up to 180°

and also that the angle 115° is the other part of a 180° total

180=115+y

180-115 =65

then the inside angle at Y  is 65°

add the three inside (interior of the triangle) angles up

180= 65 + (4k+5) + (6k+10)

180 = 65 + 10k + 15

180 = 80 + 10k

100  = 10k

10 = k

see how I did that?
