Answer:
[7.25, 7.35)
Step-by-step explanation:
The least significant digit is in the <em>tenths</em> place. The error can be as much as <em>half of one tenth</em>, or 0.05.
The lower bound is ...
7.3 - 0.05 = 7.25 . . . . . error subtracted from value
The upper bound is ...
7.3 + 0.05 = 7.35 . . . . . error added to value
Since 7.35 is rounded up to 7.4, the maximum value of L must be less than that.
7.25 ≤ L < 7.35 . . . meters
_____
In many cases, the upper bound on L is taken to be exactly 7.35. For all practical purposes it is. If you're asked for upper and lower limits, you'd have to say they are 7.35 and 7.25 m, respectively.
After the 15% discount, Maria pays 85% of the cost. That cost is the sum of the fixed cost and the variable (per visit) cost.
... (updated cost) = 0.85×($150 +$30×a)
... (updated cost) = 127.50 +25.50a . . . . in dollars
Answer:
The answer is:
C.
Step-by-step explanation:
Given:
Where is the heartbeats per minute and
is the age of person
To find:
Age of person in terms of heartbeats per minute = ?
To choose form the options:
Solution:
First of all, let us have a look at the given equation:
It is value of in terms of .
We have to find the value of in terms of .
Let us divide the equation by 0.8 on both sides:
Now, subtracting 220 from both sides:
Now, multiplying with -1 on both sides:
So, the answer is:
C.
