Let the original bill be
, then the final bill after the charges been added are
, where
is the increase in the bill by 0.2 (100%+20% = 120% = 1.2)
The range of the original bill is
200 <
< 800, subtract each term by 25
175 <
< 775, divide each term by
145.83 <
< 645.83
Hence, the range of the original bill is between $145.83 and $645.83
Answer:
7.92%
Step-by-step explanation:
Given the following
Weight of package at home = 20.2 ounces.
Weight of the package at the office = 18.6ounces
Decrement = 20.2 - 18.6
percentage error = decrement/wt at home * 100
percentage error = 1.6/20.2* 100
percentage error = 160/20.2
percentage error = 7.92
HEnce the percent error in the weight of the package is 7.92%
4/11 * 10/8
Multiplying fractions
1) multiply the numerators: 4 * 10 = 40
2) multiply the denominators: 11 * 8 = 88
3) simplify the fraction
40/88 ⇒ 10/22 ⇒ 5/11
40 ÷ 4 = 10
88 ÷ 4 = 22
10 ÷ 2 = 5
22 ÷ 2 = 11
4/11 * 10/8 = 5/11
Answer:
exponential function going through point 0, negative 2 and ending down on the right
Step-by-step explanation:
(Took the test, also seen as "Option A", this graph goes down and hits the y line at 0,-2.)
Answer: -b - 9
Step-by-step explanation:
First, since the a cancel eachother out we are left with (4-b) + (-6-7)
Second, you want to add the -6 and -7 to get -13, so (4-b) - 13
Finally, add the 4 to the negative 13 to get (-b - 9)
Hope this helps.
