Consider the set n of positive integers to be the universal set. sets h, t, e, and p are defined to the right. determine whether or not the sets upper e prime font size decreased by 10 and upper p prime are disjoint. h equals startset n is an element of upper n vertical line n greater than 100 endset t equals startset n is an element of upper n vertical line n less than 900 endset e equals startset n is an element of upper n vertical line n is even endset p equals startset n is an element of upper n vertical line n is prime endset

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

b i think

step-by-step explanation:

not really sure

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
