Answer:e
Step-by-step explanation:
The equation for the submarine is given as y =-240x
Where y is the distance of the descent
x is the time in hours
and -240 is the rate of distance per unit time
To calculate how long it will take this submarine to reach the descent
x = y /-240
The answer is 29.00 hope this helps
Answer:
9/2 or 4 1/2
Step-by-step explanation:
- 3/4 ÷ 1/6 = 3/4 × 6
- 3/4 × 6 = 18/4
- 18/4 = 9/2
- 9/2 = 4 1/2
Therefore, the answer is 9/2 or 4 1/2.
Answer:
0.80
Step-by-step explanation:
The z-score is found from the formula ...
Z = (X -μ)/σ
Z = (77 -73)/5 = 4/5 = 0.80
Jennifer's Z-score was 0.80.
Company A charges $75.50 and 14¢ per mile, then for x miles, Company A charges 75.5 + 0.14x dollars
Company B charges $30.50 and 9¢ per mile, then for x miles, Company B charges 30.5 + 0.09x dollars
Subtracting the second equation to the first one,
75.5 + 0.14x
-
30.5 + 0.09x
----------------------
45 + 0.05x
For x miles, Company A charges 45 + 0.05x dollars more than Company B.
