Help pls If the 10,000 day war started on a Thursday, on what day did it end?

Saturday.

Step-by-step explanation:

There are 7 days in a week.

. . . . . . . . . . . . 10,000 days

10,000 days = = 1428.57142847 weeks

. . . . . . . . . . . . 7 days / week

My answer indicates 1428 full weeks, the decimal portion indicates a partial week that is added to the number of full weeks.

that mean we need to convert this decimal portion into the number of days.

0.57142847 weeks  x 7 days / week = 4 days

If the war starts on Wednesday, our calculations above tell us the 10,000th day occurs 1428 full weeks plus 4 additional days later.

A full week has 7 days, for a full week starts on Wednesday,that mean it will end on a Tuesday because:

Wednesday = day #1

Thursday = day #2

Friday = day #3

Saturday = day #4

Sunday = day #5

Monday = day #6

Tuesday = day #7

At the end the 1428th (full) week is on a Tuesday.

Then that's when we add the partial week of 4 days, we get:

Wednesday = 1 day later

Thursday = 2 days later

Friday = 3 days later

Saturday = 4 days later.

Therefore, 10,000 days from Wednesday is a Saturday.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

cosine
