Answer:
The c statement is not true.
Step-by-step explanation:
We need to check every statement to determine which one is false.
a. The old tax rate was 6% and the new one is 18%. The difference between the new and the old one will give us how much it's been increased. So 18-6=12, meaning the tax has increased 12%, so this statement is true.
b. If we multiply by 3 the old tax rate we get 6x3=18, which is the same as the new tax rate, so this statement is also true.
c. Increasing the tax rate 100% would mean multiplying by 2, since 100% is the same as the number, so adding that to the same number would double the amount. By the same logic, increasing it 200% would be the same as multiplying it by 3, and by 4 with a 300% increase. Since we already determined that the new tax was 3 times the old one, this statement is false, and the d. statement is true.

Answer:
k=67/1360
Step-by-step explanation: Step 1: Simplify both sides of the equation.
201=4080k
Step 2: Flip the equation.
4080k=201
Step 3: Divide both sides by 4080.
4080k
4080
=

Answer:
Sets
Step-by-step explanation:
1) Set can be defined as a collection of objects that are well defined and distinct.
2) Since each idea has its own unique value or characteristic, they can be considered as objects.
3) Thus, a collection of ideas can be considered as a set.
4) In this case we would define the null set as the set with no ideas.
5) The sets can be represented with the help of curly brackets { }.
6) We can represent it in the set form as:
{Idea 1, Idea 2, Idea 3, Idea 4,...}
7) It can be considered a countable set as we can always count the number of ideas.
8) It is a finite set.
Answer:
60 pound
Step-by-step explanation:
Calculation for How many pounds of regular coffee should he use
Let pounds of regular coffee be x
Let value of regular coffee be 5x
Let cost of gourmet coffee be 8
Let value of gourmet coffee be 8*30
Let pounds of mixture be 30+x
Let value of mixture be 6(30+x)
Equation:
5x+(8*30)=6(30+x)
5x+240=6(30+x)
Now Let Solve for x:
5x+240=180+6x
240-180=6x-5x
60=1x
x=60/1
x=60
Therefore, he should use $60 pounds of regular coffee
