Answer:
1.) 18 is decreasing by 83%
2.) 16 is decreasing by 12.5%
Step-by-step explanation:
Part ÷ Whole = Percent (decimal form)
1.) First, you subtract the smaller number from the larger number: 18 - 3 = 15. Then you find the percent of the part: 15 ÷ 18 = 0.833333333333. This can be rounded to 0.83. Multiply 0.83 by 100 to get the percentage: 0.83 • 100 = 83%. To check your answer, multiply 0.83 by 18. It checks out. 18 is being <em>decreased</em> by 83%.
2.) Subtract 14 from 16 to get 2. Then divide 2 by 16: 2 ÷ 16 = 0.125. Multiply that by 100: 0.125 • 100 = 12.5%. To check this, we multiply 0.125 • 16 = 2. It works. So, 16 is being <em>decreased</em> by 2%.

The slope of the line should be -3/2
A worker is paid $0.10 on the first day, $0.30 on the second day, $0.90 on the third day, $2.70 on the fourth day, and so on.
Notice that the pattern of getting wages is 3 times of the previous day.
Like the wages for the first day= 0.10
Second day = 0.10*3 = 0.30
Third day = 0.30 *3 = 0.90 And so on.
Hence the wages represent a geometric sequence where
first term: a = 0.10 and common ratio: r = 3.
And we need to find the total does the worker earn after working 14 days:.
Formula to find the sum of nth term a geometric sequence is:
=
=
=
=
= 239148.4
So, he will earn $239148.40 fter 14 days.
Hope this helps you.
Answer:
5x + 15 = -5x - 15
10x = -30
x = -3
y = 5(-3) + 15 = -15 + 15 = 0
(-3,0)

There are 17 subs that are to be shared between 22 children. To get that we divide 17 by 22.
∴ 17 ÷ 22 = 17/22
= 0.77272727...
From the choices we can get the closest fraction by converting them to decimals.
1/2 = 0.5
The difference from the correct answer = 0.77 - 0.5 = 0.27
3/4 = 0.75
The difference from the correct answer = 0.77 - 0.75 = 0.02
2/3 = 0.67
The difference from the correct answer is 0.77 - 0.67 = 0.1.
The closest amount is 3/4 since it has the least deviation of 0.02 from the correct amount.
