Bally Manufacturing sent Intel Corporation an invoice for machinery with a $13,100 list price. Bally dated the invoice August 01 with 3/10
EOM terms. Intel receives a 40% trade discount. Intel pays the invoice on August 14. On August 10, Intel Corporation returns $100 of the machinery due to defects. What does Intel pay Bally on August 14?
The Intel pays $7,760 to Bally Manufacturing on August 14.
The first step in calculating what Intel Corporation pays Bally on August 14 is to determine the net price of the machinery after the trade discount and the return of $100 due to defects.
The trade discount of 40% is calculated as follows:
Discount = List price × Discount rate
Discount = $13,100 × 0.40 = $5,240
So the net price of the machinery after the trade discount is:
Net price = List price - Discount
Net price = $13,100 - $5,240 = $7,860
After Intel returns $100 of machinery, the cost of the machinery is further reduced to:
Net price after return = Net price - Return
Net price after return = $7,860 - $100 = $7,760
Since the payment terms are 3/10 EOM (end of month), Intel receives a discount of 3% if payment is made within 10 days. The 10-day period begins on August 1 and ends on August 10 (the payment due date). Since Intel pays the bill on August 14, payment is late and the 3% discount does not apply.

Roland has built a circuit, and is using a device called an
ammeter to measure how quickly electrical current is flowing
through the circuit. He calculates that the current should be
0.180 amps, but he measures the current as 0.173 amps. What
is Roland's percent error?
Roland's percent error is approximately 3.889%.
This means that his measured value differs from the actual value by 3.889% or 0.03889 in decimal form.
The positive sign indicates that Roland's measured value is slightly lower than the actual value.
To calculate Roland's percent error, we can use the formula:
Percent Error = (|Measured Value - Actual Value| / Actual Value) \(\times\) 100
Given that Roland measured a current of 0.173 amps while expecting a current of 0.180 amps, we can substitute these values into the formula:
Percent Error = (|0.173 - 0.180| / 0.180) \(\times\) 100
Simplifying the expression within the absolute value:
Percent Error = (|-0.007| / 0.180) \(\times\) 100
Since the absolute value of -0.007 is 0.007, we have:
Percent Error = (0.007 / 0.180) \(\times\) 100
Calculating the division:
Percent Error = 0.03889 \(\times\) 100
Percent Error = 3.889%.

During 2016 the price of a good increased by 8%. In the sales on 1 January 2017 all items are reduced by 25%.
(a) If the sale price of the good is $688.50, find the original price at the beginning of 2014.
(b) Find the overall percentage change.
(c) What percentage increase would be needed to restore the cost to the original price prevailing on 1 January 2016? Give your answer to one decimal place.
The original price of the good is $850.
The overall percentage change is 19%.
The percentage increase that is needed to restore to the price on January 2016 is 25%.
What is the percentage change?Percentage is the fraction of an amount that is expressed as a number out of 100. Percentage is a measure of frequency. The sign that is used to represent percentage is %.
Percentage increase in the price would be represented with this equation : (1 + percentage increase) x original price
(1 + 0.08)p = 1.08p
Percentage decrease in the price would be represented with this equation : (1 - percentage decrease) equation of the price after the percentage increase
(1 - 0.25) x 1.08p
0.75 x 1.08p = 0.81p
0.81p = $688.50
Divide both sides of the equation by 0.81
p = $688.50 / .81
p = $850
The overall percentage change : (price at the sales / original price) - 1
(688.50 / 850) - 1 = 19%
Price in January 2016 : (1 + percentage increase) x original price
1.08 x 850 = $918
Percentage change to restore the price back to the January 2016 price = (688.50 / 918) - 1 = 0.25 = 25%

Step-by-step explanation:
I need to keep 20.0 mg of a drug in my system at a minimum and a Maximum of 140. mg. The half life of the drug that I put in my system is 16 hours. I have put 100.0 mg in my system by ingesting a pill. When is the earliest I should take the next 100.0 mg pill? When is the latest?
Answer:
Therefore, the earliest time to take the next pill is after 10.85 hours and the latest time is before 15.14 hours have passed.
Step-by-step explanation:
The concentration of the drug in your system after ingesting 100.0 mg can be calculated using the formula:
C = D / V
where C is the concentration, D is the dose, and V is the volume of distribution (assumed to be constant).
At the initial time, t = 0, the concentration is:
C(0) = 100.0 mg / V
After one half-life, t = 16 hours, the concentration is:
C(16) = C(0) / 2 = 50.0 mg / V
After two half-lives, t = 32 hours, the concentration is:
C(32) = C(16) / 2 = 25.0 mg / V
After three half-lives, t = 48 hours, the concentration is:
C(48) = C(32) / 2 = 12.5 mg / V
To find the earliest and latest times to take the next 100.0 mg pill, we need to calculate the concentration at those times and make sure it stays between 20.0 mg and 140.0 mg.
Let's first find the earliest time at which the concentration drops below 20.0 mg.
20.0 mg / V = C(16 + x) = 50.0 mg / V / (2^(x/16))
Solving for x:
2^(x/16) = 50.0 / 20.0 = 2.5
x/16 = log2(2.5)
x = 16*log2(2.5) = 16*0.678 = 10.85
So the earliest time to take the next pill is after 10.85 hours.
Now let's find the latest time at which the concentration goes above 140.0 mg.
140.0 mg / V = C(16 + x) = 50.0 mg / V / (2^(x/16))
Solving for x:
2^(x/16) = 50.0 / 140.0 = 0.3571
x/16 = log2(0.3571)
x = 16*log2(0.3571) = -15.14
So the latest time to take the next pill is before 15.14 hours have passed.

The mass of a paperclip is 6.0 × 10−4 mg. If a box of paperclips has 7.23 × 104 paperclips, determine the total mass of the paperclips in the box. Write the final answer in scientific notation with the correct number of significant digits.
4.338 × 101 mg
4.3 × 101 mg
4 × 101 mg
3.62 × 100 mg
Taking into account the definition of Scientific notation, the correct answer is the first option: the total mass of the paperclips in the box is 4.338×10¹ mg.
Scientific notationScientific notation is a quick way to represent a number using powers of base 10.
The numbers are written as a product:
a×10ⁿ
where:
a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number.n is a whole number, which is called an exponent or an order of magnitude. Represents the number of times the point decimal is shifted. It is always an integer, positive if it is shifted to the left, negative if it is shifted to the right.Total mass of the paperclips
In this case, you know that:
The mass of a paperclip is 6.0×10⁻⁴ mg. A box of paperclips has 7.23×10⁴ paperclips.To know the total mass of the paperclips in the box, you must multiply the number of paperclips in the box by the mass of each paperclip:
7.23×10⁴×6.0×10⁻⁴
To multiply numbers in scientific notation, you multiply the numbers that are not powers of 10 (the numbers previously called "a") and add the exponents of 10.
(7.23×6.0)×10⁴⁻⁴= 43.38×10⁰= 4.338×10¹ mg
Finally, the correct answer is the first option: the total mass of the paperclips in the box is 4.338×10¹ mg.

Suppose the wedding planner assumes that 5% of the guests will be pollotarian so she orders 30 pollotarian meals. What is the approximate probability that more than 5% of the guests are pollotarian and therefore she will not have enough pollotarian meals
Answer:
0.0787 is the probability that more than 5% guests are pollotarian.
Step-by-step explanation:
Solution:
Given:
Assume 5% of guests will be pollotarian.
She order 30 pollotarian meals.
Expected proportion of the guest would be expected to be proletarian =3.5%
P = 0.035
n = sample size = 300
Standard error = √(p(1-p)/n)
= √(0.035(1-0.035)/300)
= √(0.033775/300)
= √0.0001125
= 0.0106
Therefore, proportion expected to be pollotarian are 0.035 give,
Or take 0.0106.
Probability that more than 5% of guests are pollotarian:
P( x> 0.05) = 1- p(x < 0.05)
= 1 – p ( z < ( 0.05 – 0.035 )/ 0.0106)
= 1 – p( z < 1.4137)
= 1 – 9213
= 0.0787
0.0787 is the probability that more than 5% guests are pollotarian.
