I would say the answer is B. 8 1/2 because 11/20 is close to 10/20 which would be the same as 1/2
Answer:
the blue one
Step-by-step explanation:
It's 3 is the factor of 9
Answer:
Step-by-step explanation:
Ok, so we start by setting the integral up. The integral we need to solve is:
so according to the instructions of the problem, we need to start by using some substitution. The substitution will be done as follows:
U=5+x
du=dx
x=U-5
so when substituting the integral will look like this:
now we can go ahead and integrate by parts, remember the integration by parts formula looks like this:
so we must define p, q, p' and q':
p=ln U
q'=U-5
and now we plug these into the formula:
Which simplifies to:
Which solves to:
so we can substitute U back, so we get:
and now we can simplify:
notice how all the constants were combined into one big constant C.
Answer:
375 sweaters sold, 125 sweaters did not sell
Step-by-step explanation:
A percent is the piece of the whole or total. 25% decrease means the total of 500 sweaters must be decreased by 25% or 1/4. We multiply 500 by 0.25 and get 125. This means that 125 less sweaters sold then expected. To find the number of sales which did occur we subtract 125 from 500.
500(0.25)=125
500-125=375 sweaters sold
