9. jane has a checkbook balance of $68.00. she then writes two checks, one for $5.00 and one for $62.50. she also deposits $75.00. she then uses her calculator to determine her new balance. which of the following is the correct series of keys she should press? a. [on/c] [68] [+] [75] [=] [5] [=] [62.50] [=] b. [68] [+] [75] [–] [62.50] [–] [5] [=] c. [on/c] [68] [–] [5] [–] [62.50] [+] [75] [=] d. [68] [+] [75] [–] [5] [–] [62.50] [=]

it is C

 she turns the calculator on, then enters her starting balance them subtracts both checks she wrote then added the deposit.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
