Yuki had a part-time job last year. She worked every week for the year and made $18 an hour. She worked 20 hours each week. Yuki saved everything that was left after paying her monthly expenses. At the end of the year, she had saved $1,850. What were Yuki’s average monthly expenses, rounded to the nearest dollar?

$16870

Step-by-step explanation:

there are 52 weeks in a year

every week, she worked 20 hours;  52x20=1040 hours

she makes $18 an hour; 1040x18=$18720

she saved $1850 at the end of the year; 18720-1850=$16870

so the yearly expenses were $16870

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to
