$2.10m+$5≤$49.10
49.10-5= 44.10
44.10/2.10 = 21
The trip home with the taxi was 21 miles long.
Answer: $543.7325
Step-by-step explanation:
room rate = $99.95 / night
Tax fee = 7% of room rate
Therefore, tax fee = 7% of $99.95
Tax fee = 0.07 × $99.95
Room charge =[$99.95 + 0.07($99.95)]
Room charge = 1.07($99.95) per night
Additional onetime untaxed fee = $9
Therefore for 5 nights :
Room charge = 5×[1.07($99.95)] +
Total room charge = 5×[1.07($99.95)] + one time untaxed fee
Total room charge = 5×[1.07($99.95)] + $9
= $543.7325
Answer:
5 generations
Step-by-step explanation:
Data provided in the question:
Number of bacteria at the beginning of a time interval
, B = 4
Number of bacteria at the end of the time interval, b = 128
Now,
The relation between the bacteria at the beginning, bacteria at the end and the number of generations (n) is given as:
b = B × 2ⁿ
Therefore,
on substituting the respective values, we get
128 = 4 × 2ⁿ
or
2ⁿ = 32
or
2ⁿ = 2⁵
or
n = 5
hence,
5 generations
a. years since 1990 (t) = 30
enrollment: n = -0.3|30 - 8|+11 = -0.3*22 + 11 = 4.4, which means 4400 students
b. Replacing into the equation with n = 10, we get:
10 = -0.3|t - 8|+11
10 - 11 = -0.3|t - 8|
(-1)/(-0.3) = |t - 8|
10/3 = |t - 8|
t - 8 = 10/3 or t - 8 = -10/3
t = 10/3 + 8 t = -10/3 + 8
t = 11 1/3 t = 4 2/3
t = 11 1/3 corresponds to year 1990 + 11 = 2001
t = 4 2/3 corresponds to year 1990 + 4 = 1994
Answer:
The answer is x = y² .
Step-by-step explanation:
In order to make x the subject, you have to square to both sides to get rid of square root :
