Answer:
In 1 day, 1.70
In two days 0.022
Note; Unit was not given in the question, I would have included it
Step-by-step explanation:
Here, we are to calculate the amount of caffeine remaining in the body.
To calculate this, we simply substitute for the number of hours t in the equation.
In one day , we have 24 hours
So our substitution will be t = 24
Hence; for a day;
g(24) = 130(0.8346)^24 = 1.70
For two days, we have t = 48 hours
Thus; g(48) = 130(0.8346)^48 = 0.022
What was the distance from P to n, shown in the figure?
A. -3
B. 1
C. 4
D. 5
Answer:
D. 5
Step-by-step explanation:
Assuming 1 box = 1 unit on the coordinate grid, therefore:
Coordinate of point P on the graph = 1
Coordinate of the point at which the ray from point P meets at line n = -4
Distance from P to n = |1 - (-4)|
= |1 + 4|
Distance from P to n = 5 units
The answer is D. 5

Which diagram provides a counter example to the statement below?
“Supplementary angles are never congruent.”
Two or more angles are supplementary if and only if they can add up to [tex]180^{o}[/tex]. Thus, the appropriate option would be C.
Supplementary angles are angles that add up to the value of angle on a straight line i.e [tex]180^{o}[/tex].
Congruent property of angles implies that they have equal value.
Thus, the given statement that: “Supplementary angles are never congruent”, implies that they can not be equal in value. Thus the contrary to the statement would be: “Supplementary angles are sometimes congruent.”
Considering the figures given in the question, the counter example to the given statement is the figure in option C. [tex]180^{o}[/tex]. Because angle 1 and 2 are approximately equal.

Two airlines each made 30 flights. The dot plots shown compare
how many minutes the actual arrival times were before or after
the scheduled arrival times of these flights.
Negative numbers represent the minutes the flight arrived before its scheduled time.
Positive numbers represent the minutes the flight arrived after its scheduled time.
Zero indicates the flight arrived at its scheduled time.
Assuming you want to arrive as close to the scheduled time as possible, from which
airline should you buy your ticket? Justify your response by addressing both the
measures of center and spread of the distributions.

Quick question
Select True or False. (1 point)
The expression 4x − 2(5x − 1) is equivalent to the expression 2 + 6x.
True
or
False
Answer:
False
Step-by-step explanation:
Let us evaluate the problem using the proper order of operation:
4x − 2(5x − 1)
To solve this problem, we use the order of operation called PEMDAS;
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
Now, since operations inside the parentheses are of the utmost priority, let us solve this;
4x − 2(5x − 1)
= 4x - 10x +2
= -6x + 2 or 2 - 6x
We see that the solution give is false.
Jaime’s older brother and his three friends want to split the cost of lunch. They also want to leave a 15%–20% tip. How much should each person pay?
Answer:
First you have to split the cost of the meal and percentage so
$78.00 divided by 4 that's $19.50 each then after the 20% each would pay $23.40
Each person pay $23.4.
Given, from the fig the total cost of lunch without tip is $78.
Now, Jaime’s older brother and his three friends want to split the cost of lunch between them. So there is total 4 person.
Now each person have to pay [tex]\frac{78}{4} = $ 19.5[/tex] dollars.
Further they decided to pay tip say 20% so, the amount of tip is 20% of $78.
On calculating amount of tip [tex]=\frac{20}{100} \times 78=15.6[/tex].
Tip is divided among them so per person has to pay tip [tex]=\frac{15.6}{4} =3.9[/tex] dollars.
So, the total amount each person has to pay [tex]=19.5+3.9=23.4[/tex] dollars.
Hence each person pay $23.4.

Answer:
w(15)=112.5
Step-by-step explanation:
All you have to do is put the number in the parentheses in the place of the variable, which in this case is h, and perform the prescribed operation.
In this case, you make the equation w(15)=7.5(15) which you can rewrite as
w(15)= 7.5×15, which gives . you 112.5 as the product.
Sadie works 5 more hours than Kerry does, and Mark works 2 hours less than Kerry. Together they work 120 hours. How many hours does each person work?
Answer:
Sadie:44 Kerry:39 mark:37
Step-by-step explanation:
(5+w) + w + (w-2)=120
-5 from both sides
w+w+(w-2)=115
+2 from both sides
w+w+w=117
117/3 = w
hey i need help with a math question thank you :)
Answer:
y = 60x + 20
y = 65x
0 = 5x - 20
5x = 20
x = 4 ---> 4 hours
Substitute x as 4:
y = 65 x 4
y = 260 ---> 260 miles
So the answer is A

Hector has $590 in his account. He earned $15 per hour for x hours. Jeremy has $545 in his account. He earned $20 per hour for x hours. They both worked the same number of hours and now have the same amount of money. What is the number of hours that each person worked? Write and solve an equation.
Answer:
equation = 590 + 15x = 545 + 20x
No. of hours worked = 9
Step-by-step explanation:
Given that both worked for same number of hours
and
Jeremy worked for for x hours
it meant that Hector also worked for x hours(it is also mentioned same in the problem)
now that we know the number of hours worked in form of x
lets find
total money in their account if they worked for x hours
___________________________________________
For Hector
Money in Hector's account = $590
Earning for Hector in 1 hour = $15
Earning for Hector in x hour = x*Earning for Hector in 1 hour = $15x
Total money in with Hector after x hours of work
= Money in Hector's account + Earning for Hector in x hour = $590 + $15x
Similarly
For Jeremy
Money in Jeremys account = $545
Earning for Jeremy in 1 hour = $20
Earning for Jeremy in x hour = x*Earning for Jeremy in 1 hour = $20x
Total money in with Jeremy after x hours of work
= Money in Jeremy's account + Earning for Jeremy in x hour = $545 + $20x
Given that they same amount of money
thus
$590 + $15x = $545 + $20x
$sign gets cancelled from both sides
590 + 15x = 545 + 20x Thus, we got the required equation
=> 590 - 545 = 20x - 15x
=> 45 = 5x
=> x = 45/5 = 9
Thus, both of them worked for 9 hours
