At a school there are 864 students and 80 staff members.5/8 of the students are boys.1.Every Wednesday, a meeting for all the teaching staff is held. if 13/16 of the staff members are teaching staff, how many staff members are invited to the meeting.2.On the last Wednesday of may,1/5 of the teaching staff was not in school for a field trip. How many staff members were at that meeting?

depends on how many days you are talking about

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.

-5, your answer was correct
