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:
7 feet
Step-by-step explanation:
Volume of a cyclinder = πr^2h
Volume of a cyclinder = 1952
π = 3.14
r = ?
h = 2r
Volume of a cyclinder = πr^2h
1952 = 3.14 * r^2 * 2r
1952 = 3.14 * 2r^3
1952 = 6.28r^3
Divide both sides by 6.28
r^3 = 1952 / 6.28
= 310.83
r^3 = 310.83
Find the cube root of both sides
r = 6.77 feet
Approximately 7 feet

Nicole is 13 years old because x + 5 = 18
Step-by-step explanation:
Answer:
1 . 4 hrs , 2 . total 400 miles because the first train had travelled 160 miles and 2nd one had travelled 240 miles
Step-by-step explanation:
in 1. use relative motion concept I. e. you sir on 1st train and put velo. of same mag. and in oppo. direction on the train on which you have sit and do the same with the velocity only with 2nd train means you stop the train on which you are sitting and put the velocity of the train on which you are sitting on 2nd train but in oppo. direction , so now the relative velocity comes out to be 20 mph and then apply formula time = Srel / Vrel and here we can find S rel by multiplying the velo. of 1st train by given time I. e. 2 hrs and in 2. multiply the time calculated by us by the velocity of both trains and by which you get the dist. travelled by both trains and then add them to get final answer.
