Karen spends $600 on bills each month. Of this total, 10% is for phone, 1/4 is for internet, and 3/5 is for utilities. If the rest of the total is for savings, how much will Karen be able to save each month?

$30

Step-by-step explanation:

divide 600 by 10 to get 60

divide 600 by 4 to get 150

divide 600 by 5 to get 120, then multiply 120 by 3 to get 360.

600-60-150-360=30

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
