7. The milligrams of aspirin in a person's body is given by the equation a = 500 - (3/4)
where t is the number of hours since the patient took the medicine.
b. In the equation, what does the 500 tell us about the situation?
c. In the equation, what does the tell us about the situation?
d. Graph the equation for values of t between 0 and 4.
Answer:
a. 281.25 grams
b. The 500 represent the original amount of aspirin.
c. 3/4 tells us what amount of the aspirin remains after every hour.
d's answer is in the picture. Just copy the line.
Step-by-step explanation:
A is the only part that needs any explanation.
Since the t represent hours, I'll subsititute t for 2.
500 * (3/4)²
3/4 squared is 9/16.
500 * 9/16
Multiply 500 by 9 to get 4500.
4500/16
Simplify 4500/16 to 1125/4 (4 is canceled out.)
1125/4
Divide 1125 by 4 to get 281.25
281.25
281.25 grams of aspirin will be in the patient body after two hours.

Answer:
x = 7
y = 0
Step-by-step explanation:
Equation: 2x - 9y = 14
We are given that x = -6y + 7
So we substitute (-6y + 7) for "x" in the equation 2x - 9y = 14
* substitute *
2 ( -6y + 7 ) - 9y = 14
now we solve for y using basic algebra
step 1 distribute the 2
2 * -6y = -12y
2 * 7 = 14
now we have -12y + 14 - 9y = 14
step 2 combine like terms
-12y - 9y = -21y
now we have -21y + 14 = 14
step 3 subtract 14 from each side
14 - 14 cancels out
14 -14 = 0
now we have -21y = 0
step 4 divide each side by -21
-21y / -21 = y
0 / -21 = 0
we're left with y = 0
now to find x
To find x we substitute 0 for "y" in x = -6y + 7
* substitute *
x = -6 ( 0 ) + 7
-6 * 0 = 0
we're left with x = 7

Answer:
Equation: 65+1.50m=78.50
Solution to the equation= 9 minutes
Step-by-step explanation:
The parents have to give 65 dollars for their children to be under care till 6 o'clock. AFter 6 o'clock, they had to pay 1.50 dollars for one minute. This parent gives a total of 78.50 dollar for that day. So, the equation is :
65+1.50m=78.50
(btw, m stands for minutes)
So to solve the equation:
1.50m=13.50
m= 9
someone please helppp
Answer:
7
Step-by-step explanation:
We know that alternate angles ( Z angles) are equal
So, the angle that is adjacent to (13x + 2) = (12x+3)
First, calculate the measure of the angle adjacent to (13x+2)
We know that the angles on a straight line add up to 180 degrees.
Therefore, the angle adjacent to (13x+2) = 180-(13x+2)
Simplify this to: 178-13x
So, now we have an equation
178 - 13x = 12x + 3
Rearrange to find the value of x
25x = 175
x = 7
Hope this helps.

Answer: Pretty sure it would look like this
Step-by-step explanation:
You have read 25 pages of a book. You plan to read an additional 10 pages each night. Write the explicit formula to represent the number of pages you will read after n nights.
Answer:
p=10n+25
Step-by-step explanation:
Let's have p represent the number of pages you will read. If you read 10 pages per night, then you are multiplying 10 by the number of nights, which gives you 10n. Because you have already read 25 pages, you want to add to the 10n to give you the equation of p=10n+25
Answer:
Pages= 25 + 10n
Step-by-step explanation:
Since the starting point is 25, that remains constant. 10n represents 10 pages per night.

Need help with this math problem.
I forget all my vocabulary so hopefully someone else can correct me if the words I use aren't correct. But the following is definitely a function. "Although two x values correspond to a singular y value, the function passes a vertical line test. Meaning that it is ok to have values of x that equal the same y values, however two values of y assigned to the same x value would make the function undefined."
Hope this helps! The only vocabulary in this that you would really need is "corresponding," and (if you learned about it, you may not have yet) "vertical line test"
pls help with this immediately!!!! i’ll be giving brainiest to those who provide the correct answer. if u leave a link, have fun getting reported.

A TV that usually sells for $174.45 is on sale for 15% off. If sales tax on the TV is 8%, what is the price of the TV, including tax?
Answer:
$160.14
Step-by-step explanation:
15% of 174.45 = 26.16
174.45 - 26.16 = 148.28
8% of 148.28 = 11.86
148.28 + 11.86 = 160.14
A rectangle has a width of (4g) and a length of (28 - 3). The perimeter of the rectangle is 54 units. What is the
value of g?
Answer:
Step-by-step explanation:
sorry do not .know
To find the value of g, we need to use the formula for the perimeter of a rectangle, which is:
P = 2(l + w)
where P is the perimeter, l is the length, and w is the width.
We are given that the width is 4g and the length is 28 - 3 = 25, so we can substitute these values into the formula:
54 = 2(25 + 4g)
Next, we can simplify the equation by first distributing the 2:
54 = 50 + 8g
Then, we can isolate g on one side of the equation by subtracting 50 from both sides:
4 = 8g
Finally, we can solve for g by dividing both sides by 8:
g = 4/8
Simplifying this expression gives us:
g = 1/2
Therefore, the value of g is 1/2.

if my class starts at 11:45 am and ends at 1:15 pm but I leave early at 12:30 pm how much time have I spent in class?
Answer:
45 minutes
Step-by-step explanation:
you can disregard the 1:15 pm time
Answer:
45 minutes.
Step-by-step explanation:
You can ignore the 1:15 pm, as it's not relevant to the question of how much time you have spent in class.
11:45am to 12:30pm
Adding 15 minutes turns 11:45 am to 12:00 pm
Add another 30 minutes, it becomes 12:30 pm.
Calculate the sum of the minutes:
15+30 = 45 minutes.

9 - 3/5 as a improper fraction
Answer:
42/5
Step-by-step explanation:
Answer: heres the right aswer 48/5.
This becomes the numerator of the improper fraction; the denominator of the new fraction is the same as the original denominator. For example, we can convert 9 3/5 into a mixed number: 9×5 = 45, and 45 + 3 = 48. Thus, 9 3/5 = 48/5.
1,345,456,234,234,345,234,-1234,567,890=? My subsititue is being mean so we can not use calculatars and I do not like to cheat anyway but in this case (yes)
Answer:
1,345,456,232,999, 777,344
Step-by-step explanation:
1,345,456,23 4, 2 3 4, 3 4 5, 2 3 4,
-1 2 3 4, 5 6 7, 8 9 0
1,345,456,23 2, 9 9 9, 7 7 7, 3 4 4
So we write the ones under the ones, tens under the tens starting from the right hand side.
The first numbers can be easily subtracted as 4 is greater than zero. Then comes 3 which is less than 9 so we borrow 1 digit from the left to right to make it 13 and subtract 9 from it and get a 4. Then we are left with 1 as we have already borrowed 1 digit. As 1 is less than 8 we again borrow 1 digit from the left to make it 11 and subtract 8 and get 3. So the next number is 4 as we have already borrowed 1 and it is less than 7 . Again we will borrow 1 digit from the left to make it 14 and subtract 7 to get a 7.
So the process continues until we get the answer.

An 18-foot ladder is leaning against the side of a building such that its base makes an angle of 65º with the ground. How far from the side of the building, b, should the base of the ladder be placed? Round to the nearest tenth of a foot.
Hello!
This problem is about relating trigonometric values to an unknown side.
We are given an angle side, and we can determine that another angle made would be a 90 degree angle.
Meaning we could solve for the third unknown angle by knowing that the interior angles of a triangle add up to 180 degrees.
[tex]65+90+x+180[/tex]
[tex]x=180-90-65[/tex]
[tex]x=25[/tex]
After knowing this, we could use the law of sines, which states that the ratio of a side and the sin of its opposite angle are equal to any other ratio.
[tex]\frac{16}{sin(90)}=\frac{b}{sin(25)}[/tex]
[tex]b=16sin(25)[/tex]
Make sure to be in degrees when putting this in a calculator.
[tex]b=6.8[/tex]
