Answer:
simple interest
Step-by-step explanation:
this is because r is interest rate, p is principal, and t is time
Answer:
simple interest
Step-by-step explanation:
Simple interest rate is defined as: I = p * r * t. So you're taking the principle amount (initial amount loaned) and multiply it by the interest rate. This gives you the interest rate in a year (usually, depends on time unit of t). Generally speaking, it gives you the interest over a specific amount of time. Now multiply it by the amount of time that's passed. So you're just calculating the total amount of interest. So the I stands for the simple interest.
Two friends, Olivia and Melanie, took summer jobs. The equation y=22.2xy=22.2x represents Melanie's earnings in dollars and cents, yy, for working xx hours. Olivia earned $1156 in 40 hours. How much less per hour does Melanie earn than Olivia?
Answer:
$6.70 per hour
Step-by-step explanation:
We want to compare the pay for 1 hour's work.
Melanie's payThe equation tells us that her pay for working 1 hour can be found from the equation using x=1.
y = 22.2x
y = 22.2×1 = 22.2 . . . . pay for 1 hour
Melanie earns $22.20 per hour.
Olivia's payWe assume that Olivia's pay is proportional to hours worked, so pay for 40 hours will be 40 times 1 hour's pay.
pay per hour = $1156/(40 h) = $28.90/h
Olivia earns $28.90 per hour.
Pay differenceThe difference in their rates of pay is ...
$28.90 -22.20 = $6.70
Melanie earns $6.70 less per hour than Olivia.

Dr. Dominic Estores has written a prescription for a patient to take a preoperative medication at 2200 on the evening before his scheduled surgery. Using the standard time system, what time should you tell the patient to take his medication?
Using the conversion from the 24-hour system to the AM/PM system, the patient should take the medicine at 10 PM.
How to convert from 24 hours to AM/PM?If the hour is between 0 and 11:59, the hour is kept with AM.If the hour is 12, it is PM.If the hour is between 13 and 23:59, the hour the remainder of the division of the hour and 12, PM.22 divided by 12 has remainder 10, hence 22 is equivalent to 10 PM.

Given that a bag of m&ms has 21 brown candies, 15 orange candies, 10 yellow candies, 14 red candies, and 5 green candies, find the probabilities
The probability of drawing brown candies , orange candies, yellow candies, red candies, green candies is 0.323 , 0.231 , 0.154 , 0.215 ,0.077
What is Probability ?Probability is the study of likeliness of an event to happen.
It is given that a bag of candies that have
21 brown candies
15 orange candies,
10 yellow candies,
14 red candies,
5 green candies,
probabilities of drawing each candy =?
Total Candies = 21 +15+10+14+5 = 65
Probability = No. of chances / Total outcomes
Probability of drawing Brown candies = P(B) = 21 /65 = 0.323
Probability of drawing Yellow candies = P(Y)= 10/65= 0.154
Probability of drawing Orange candies = P(O) = 15/65= 0.231
Probability of drawing Red candies =P( R) = 14/65= 0.215
Probability of drawing Green candies = P(G) = 5/65= 0.077
Therefore the probability of drawing brown candies , orange candies, yellow candies, red candies, green candies is 0.323 , 0.231 , 0.154 , 0.215 ,0.077.

The graph of f(x) was vertically translated down by a value of k to get the function g(x) = 5x + k. What is the value of k?
The value of k in g(x) = 5^x + k is -7
How to determine the value of k?The complete question is added as attachment
The functions are given as:
f(x) = 5^x
g(x) = 5^x + k
From the attached graph, we can see that:
f(x) is shifted down by 7 units to form g(x)
This means that:
g(x)= f(x) - 7
This gives
g(x) = 5^x - 7
Substitute g(x) = 5^x - 7 in g(x) = 5^x + k
5^x + k = 5^x - 7
This gives
k = -7

There are two values of k based on the assumption that PQ = QR and the definition of distance and the Pythagorean theorem, k₁ = 7 and k₂ = 1.
How to find the missing value of a coordinate
Herein we can find the value of the missing coordinate of point by the Pythagorean theorem, which is described below:
PQ = QR (1)
[tex](Q_{x}-P_{x})^{2} + (Q_{y}-P_{y})^{2} = (R_{x}-Q_{x})^{2} + (R_{y}-Q_{y})^{2}[/tex]
If we know that P(x, y) = (- 2, 1), Q(x, y) = (1, 4) and R(x, y) = (4, k), then the missing value of the point R is:

(k - 4)² = 9
k - 4 = ± 3

Step-by-step explanation:
OK, I think you can prove this with the theorem that any prime greater than 3 is 6n-1 or 6n+1, for integer n. In other words, any prime is near a multiple of 6; it is either one less or one more. The proof for this is very easy, look it up.
Given this fact, if two primes (p,q) are 70 a part, this means the first one has to be a case of 6n+1 and the second one has to be a case of 6n-1. Why? Because the nearest multiple of 6 is 72 and with +1 on one end and -1 on the other end, you can reach a "gap" of 70.
Now for the next two primes (q,r) the same must hold. Only, it can't because this requires q to be both 6n-1 and 6n+1.
