Answer:
10+2.50*L
Step-by-step explanation:
It first says they charge $10 PLUS $2.50 per lap.
If I were to go only 1 lap my total would be $12.50, that's why the number of laps is labeled L because we don't know how many laps the customer is going to make.
The milligrams of aspirin in a person's body is given by the equation a=500(3/4) ^t, where t is the number of hours since the patient took the medicine. How much aspirin will be in the patient's body after two hours?
The amount of aspirin that will be present in the patient's body after two hours is 281.25 milligrams.
How to evaluate a given mathematical expression with variables if values of the variables are known?You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.
For this case, we have:
Amount of aspirin in a person's body (in milligrams) after t hours of taking the medicine is:
[tex]a = 500\times(\dfrac{3}{4})^t[/tex] (in milligrams)
For t = 2 hours, we get:
[tex]a = 500\times(\dfrac{3}{4})^2 = 281.25 \: \rm milligrams[/tex]
Thus, the amount of aspirin that will be present in the patient's body after two hours is 281.25 milligrams.

1101101+11011 in binary numbers please help
Answer:
The answer is 1000 1000
Step-by-step explanation:
In HEX, it would be 88.
In DEC, it would be 136.
In Oct, it would be 210.
Binary, how to add numbers together.
1101101
+ 11011
10001000
This is just like adding regular numbers together.
For example, when you add 88 to 55, this is what will happen
1(r)
88
+ 55
13(+1) 3
143
With binary, when 1 and 0 are added together, the result is 1. When 1 and 1 are added together, the result is 1 and 0 (1 being the "remainder", or the number that is carried over. This number is then added to the next part of the number when adding, just like in normal addition.

Find the value of x. Then find the angle measures of the triangle.
3x°
40°
Sum of angle
measures: 180°
Answer:
x=35°
3x= 105°
Step-by-step explanation:
[tex]40 + 3x + x = 180[/tex]
[tex]40 + 4x = 180[/tex]
[tex]4x = 180 - 40[/tex]
[tex]4x = 140[/tex]
[tex]x = \frac{140}{4} [/tex]
[tex]x = 35[/tex]
[tex]3x = 3(35) \\ 105[/tex]

Find the equation of the line shown.
Answer:
4y + x = 8
Step-by-step explanation:
firstly, we choose any 2 points on the line
point 1 = (0,2)
point 2 = (4,1)
x1 = 0, x2 = 4
y1 = 2, y2 = 1
from,
[tex] \dfrac{y2 - y1}{x2 - x1} = \dfrac{y- y1}{x- x1} [/tex]
[tex] \dfrac{1 - 2}{4 - 0} = \dfrac{y- 2}{x- 0} [/tex]
[tex] \dfrac{ - 1}{4} = \dfrac{y- 2}{x- 0} [/tex]
Cross multiplying,
-1(x) = 4(y - 2)
-x = 4y - 8
4y + x = 8

What is the value of f(12)?
Answer:
116
Step-by-step explanation:
To find f(12), plug in 12 as x in the equation:
f(x) = 2/3x + 9x
f(12) = 2/3(12) + 9(12)
f(12) = 8 + 108
= 116
So, f(12) = 116
