Answer:
8 Bows
Step-by-step explanation:
I will be using money as an example.
It takes 4 quarters to make a dollar. (1/4 1/4 1/4 1/4 = 1)
By using this method we will know that it takes 24 quarters to make 6 dollars and the additional 1/4 is an extra quarter. Now that we have 25 quarters we will divide it by 3 because it takes 3/4 to make a bow.
6x4=24
24 + 1 = 25
25/3= 8.333333
Answer:
Step-by-step explanation:
step 1
if 1,584 is decreased by 18%
we know that
Multiply the number by 0.82
step 2
The number 1,298.88 is increased by a 19%
we know that
Multiply the number by 1.19
You can convert (1/625) to an exponent, and it would be ideal to have 5 as the base of it because you want your log base to cancel it out. what i usually do in this case is just test out 5^1, 5^2, etc until i find one that matches the number i need. in this case because the number you're trying to work with is a small fraction, you'll want to use NEGATIVE exponents so it'll create a fraction instead of a large whole number:
5^-1 = 1/5
. . . keep trying those. . .
5^-4 = 1/625
so, because they're equal to one another, it'll be waaay easier after you substitute 5^-4 in place of 1/625
x = log₅ 5⁻⁴
log base 5 of 5 simplifies to 1. subbing in the 5^-4 gets rid of the log for you altogether, and your -4 exponent drops down:
x = -4 is your answer
if the exponent dropping down doesn't make sense to you, you can think of it in another way:
x = log₅ 5⁻⁴
expand the expression so that the exponent moves in front of the log function:
x = (-4) log₅ 5
then, still, log base 5 of 5 simplifies to 1, so you're left with:
x = (-4)1 or x = -4
