Step-by-step explanation:
Length of parking lot = 20 feets
Speed of tortoise which starts at the edge = 6 feets per minute
Speed of tortoise which starts 4 feets from the edge = 2 feets per minute
Equation to represent when they will be in the same spot.
Distance = speed * time
Distance of Tortoise at edge = 6ft/min * t = 6t - - (1)
Distance of the other tortoise = (4 + 2t) - - - (2)
Equating both (1) and (2)
6t = 4 + 2t
6t - 2t = 4
4t = 4
t = 4/4
t = 1
Hence, they'll be at the same spot after 1 minute.
The square root of a prime number (11) is irrational
Answer:
a) £320
b) £720
c) 2 days
Step-by-step explanation:
The question is all about inputting values and finding a result or rearranging and finding a result.
a) d = 6. C = 50(6)+20 = 320
b) d = 2x7 (7 days a week) C = 50(2x7) + 20 = 720
c) C = 120 ... 120 = 50d+20
100 =50d d = 100/50 = 2

Answer:
The following numbers ARE functions:
2, 3, 6, 7, 9, 12
Step-by-step explanation:
A function is only possible if the x values have NO REPEATING NUMBER!!!
Every number that isn't mentioned above has at least 1 number in it's x-values that repeats.
<u>Question 1</u> has the 8 and 4 with 2 numbers.
<u>Question 4</u> the 3 repeating. (There are 2 dots over the 3)
<u>Question 5</u> has numbers 1 and 5 repeating many times
<u>Question 8</u> numbers 1 and 2 are repeated twice
<u>Question 10</u> number 3 repeats twice
<u>Question 11</u> has the 1 repeated
