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: you have to give numbers
Step-by-step explanation: what
Answer:
82.22%
Step-by-step explanation:
As total expected people was 450 in the concert.
Attended only 370 people in the concert.
∴
= 82.22% of people attended the concert.
It is given in the statement that the increase in number of scones is same from Robbie till Charlie.
Let us assume that Robbie buy x scones and every boy buys y more scones than the previous ones.
The number of scones for each of the boy can be written as:
Robbie = x
Cameron = x + y
Louis = x + 2y
Tom = x + 3y
Charlie = x + 4y
Total number of scones = 60
So,
Robbie and Cameron's combined total number of scones is three sevenths of the total of Louis, Tom and Charlie. Mathematically this can be stated as:
Using Solving the two equations simultaneously:
This means, Robbie buys 8 scones,
Cameron buys 8 + 2 = 10 scones,
Louis buys 8 + 4 = 12 scones,
Tom buys 8 + 6 = 14 scones,
and Charlie buys 8 + 8 = 16 scones
Answer:
262.5 minutes or 4.375 hours
Step-by-step explanation:
7/8=0.875
60 minutes=1 hours
5 is the amount Karen played
7/8 of 60 minutes will be 52.5 minutes since 0.875*60=52.5
52.5*5=262.5 minutes
262.5/60=4.375 hours
