The post office needs to send out 1,500 letters a day to stay on top of the deliveries. after an entire year how many letters will the post office have sent out?

547,500 letters

Step-by-step explanation:

Assuming the post office sends out letter every single day of the year:

Everyday the post office sends out 1500 letters

In a year, they will send out 1500 TIMES the number of days in a year.

We know there are 365 days in a year, and if the post office works EVERY SINGLE DAY, they will send out:

1500 * 365 = 547,500 letters (in a year)

Hence,

Total (in a year) = 547,500 letters

just get this app called photo math it should be able to do those

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.
