Answer:
27: 29.93 Seconds
28: 28 ° Fahrenheit
Step-by-step explanation:
Number #27:
Given:
#1 Lap = 14.76 seconds
#2 Lap = 15.17 seconds
Steps:
1. Use the algorithm method.

Answer: 29.93 seconds

Number #28:
Given:
Wind Chill Temperature: - 18 ° F
Actual Temperature: 10 ° F
Steps:
1. Subtract 18 from 10.
Answer: - 28 ° degrees fahrenheit
Note: Whenever there is a negative sign next to a temperature, it means it's below freezing as the below freezing temperature is 0 ° Fahrenheit. This also means subtraction. In this case, you would subtract the negative amount from the positive amount creating an equation, that equation represents the degrees in fahrenheit:
10 - 18
The result should be -28.
This also means that the difference between both temperatures is 28 degrees. Wind chill creates a feeling of higher temperatures even though the actual temperature in the atmosphere was 10 ° F in this specific land structure.

Answer:
solution
given=3a+3a^2+3a^3+....+...+...3an
first term(t1)=3a
second term(t2)=3a^2
third term(t3)=3a^3
for arithmetic mean ,d1=d2
d1=t2_t1=3a^2_3a=3a(a_1)
d2=3a^3_3a^2=3a^2(a_1)
here d1 is not equal to d2.
so it's not an arithmetic series.
Again,for geometric mean,r1=r2
r1=d2/d1=3a^2/3a=a
r2=d3/d2=3a^3/3a^2=a
here ,r1 is equal to r2.
so ,it's an geometric series.
Answer:
the percent reduction is <u>33.6%</u> and the number of people who were issued a parking ticket are <u>42</u>.
Step-by-step explanation:
Given:
Last month in the village of 125 people were issued a parking ticket.
This month only 83 people were issued one.
Now, to find the percent reduction from this month to last month and the number of people who were issued a Parking ticket.
So, the reduction of the number of people who were issued a Parking ticket from this month to last month are:
125 people - 83 people = 42 people.
Thus, 42 people reduction from this month to last month.
Now, to get the percent reduction:
Therefore, the percent reduction is 33.6% and the number of people who were issued a parking ticket are 42.
