The closed formula for <span>an = an-1 – n will be found using the formula for arithmetic sequence given by:
an=a+d(n-1)
where
a=first term
d=common difference
n=number of terms
From the formula given:
a=4
d=n
thus the formula will be:
an=a+n(n-1)
an=4+n(n-1)
</span>
We know that Length = x + 16 and Width = x.
Since the perimeter of the rectangle is 2 lengths + 2 widths,
Perimeter = 2(2x + 16) = 4x + 32.
Answer:
$720
Explanation:
3 (yd³) per minute per worker.
4*3=12 yd³ per minute in total.
12*60 = 720 yd³ per hour.
8920 yd³ ÷ 720 yd³ = 12.388889 hours of work.
15$ a worker/hour x 4 workers = $60 per hour in total. Since there are only 12 whole hours in 12.388889, $60/hour x 12 full hours = $720 for all work done.
I think the question is wrong!
It must be
x-4
___= 5
x+2
Answer: x - 4= 5x + 10
or,-10 -4 = 5x - x
or, -14=4x
or,-14/4= x
Therefore, x = -14/4
Answer:
A basic formula, solving for x, guides us in the setting up of an equation: D/H x Q = x, or Desired dose (amount) = ordered Dose amount/amount on Hand x Quantity
Step-by-step explanation:
Medications are available in multiple concentrations, therefore orders written in "mL" rather than "mg" are not acceptable and require further clarification.
...
Example 2.
Step 1. Calculate the dose in mg: 18 kg × 100 mg/kg/day = 1800 mg/day
Step 2. Divide the dose by the frequency: 1800 mg/day ÷ 1 (daily) = 1800 mg/dose
