Step-by-step explanation:
After sitting on a shelf for a while, a can of soda at room temperature (73 F) is placed inside a refrigerator and slowly cools. The temperature of the refrigerator is 35 F.
The can of soda reaches the temperature of 53 F after 35 minutes. Using this information, find the value of k, to the nearest thousandth. Use the resulting equation to determine the Fahrenheit temperature of the can of soda, to the nearest degree, after 70 minutes.
Answers
Answer:
Step-by-step explanation:
Use Newton's Law of Cooling here:
[tex]T(t)=T_s+(T_0-T_s)^{-kt[/tex]
where T(t) is the temp of something after a certain amount of time, t, has gone by; Ts is the surrounding temp, and T0 is the initial temp. k is the constant of cooling. We need to first solve for this using the information given. Filling in what we know:
[tex]53=35+(73-35)^{-35k[/tex] which can simplify a bit to
[tex]53=35+(38)^{-35k[/tex] and [tex]18=38^{-35k[/tex]
Take the natural log of both sides:
[tex]ln(18)=ln(38)^{-35k[/tex]
Taking the natural log allows us to pull that exponent down out front:
[tex]ln(18)=-35k*ln(38)[/tex]
and now we can divide both sides by ln(38) to get
-35k = .794585 so
k = -.023
Now that have the value for k, we can go on to solve the rest of the problem which is asking us the temp of the soda after 70 minutes. Filling in using the k value and the new time of 70 minutes:
[tex]T(t)=35+(38)^{70(-.023)[/tex] and
[tex]T(t)=35+(38)^{-1.61[/tex] and
[tex]T(t)=35+.0028612013[/tex] and
T(t) = 35 F, basically the temp of the fridge, which is not surprising!

Step-by-step explanation:
Volume of a triangular pyramid = [tex]\frac{1}{3} bh[/tex]
where b = area of base and h = height
We are already given that the height is 17in
All we need to do is find the area of the base.
The base is a triangle with a base length of 12 in and a height of 10 in
To find the area of a triangle we multiply the base length by the height then divide by 2
so area = (12 * 10 ) / 2
12 * 10 = 120
120 / 2 = 60
Hence the area of the base is 60in²
Now we plug in the values into the formula for volume of a pyramid
[tex]V=\frac{1}{3} 60*17\\\frac{1}{3} 60=20\\20*17=340[/tex]
V = 340
Hence the answer is B

you are solving an equation to find the best length for a table you are designing. you have factored the equation as (x+1)(2x-3). Will the Solutions of the equation give you two different lengths to choose from?
A. Yes; each binomial factor produces one solution that is a possible length
B. No; One of the solutions is negative. You cannot use negative values for a length of a table
Answers
Answer: The answer is b
Step-by-step explanation:
Length is a non-negative quantity. The correct statement for solution of the equation representing length of the table is given by: Option B: B. No; One of the solutions is negative. You cannot use negative values for a length of a table
How to find the solution of an equation of the form p(x) = 0?The solution to this equation means values of variable x for which the function p(x) evaluates to 0.
For the given condition, we're given that:
The solution to the equation [tex](x + 1)(2x-3) = 0[/tex] (the question needs to include the 0 on right or some constant at least) will give the length of the table.
Since we know that
[tex]A \times B \implies A = 0\: \rm or\: B = 0[/tex] or both.
Thus, from [tex](x + 1)(2x-3) = 0[/tex], we get:
[tex](x + 1) = 0[/tex] or [tex](2x-3) = 0[/tex]
From the first equation, we get:
[tex](x + 1) = 0\\x = -1[/tex]
From the second equation, we get:
[tex](2x-3) = 0\\x = \dfrac{3}{2} = 1.5[/tex]
x represents the solution of the considered equation, thus, representing length of the table, as stated in the problem. Know that length can be 0 or positive, but cannot be negative. Thus, the first solution is not valid as it gives negative value for the length of the table.
Therefore, the correct statement for solution of the equation representing length of the table is given by: Option B: B. No; One of the solutions is negative. You cannot use negative values for a length of a table

what is the equation of this line
a. y = -3/2x+9
b. y = -2/3x+18
c. y = 2/3x+6
d. y = 3/2x+6
Answers
Answer:
A. y = -3/2x + 9
Step-by-step explanation:
In slope intercept form (y = mx + b), b represents the y-intercept. Therefore, simply look on the graph where the line intersects with the y-axis. In this case, that is all that was needed since we can clearly see that equation A is the only one with a y-intercept of 9.
Answer:
a
Step-by-step explanation:
any two points on the line are
(0,9 ) and (4,3)
slope=(3-9)/(4-0)=-6/4=-3/2
y intercept is 9
so eq. of line is y=-3/2x+9

Ms. Masi is going to be paid $11.25 per day to look after Ms. Simms’ dog. She wants to save all of her earnings, but she owes her brother $72. After the first day of dogsitting, Ms. Masi uses her earnings to pay part of her debt to her brother. After the second day, she uses her earnings to pay more of her debt. Ms. Masi plans to save every dollar of her dog sitting money as soon as she has paid her brother in full.
How many days will it take for Ms. Masi to pay her brother in full? Explain.
Answers
Answer:
7 days
Step-by-step explanation:
So! Ms. Masi earns $11.25 everyday, and is paying her brother back everyday. Let's make an equation to solve for the number of days!
11.25d = 72 (d = # of days)
Now, we have to solve this equation to see how many days (d) it will take Ms. Masi to pay her brother back.
11.25d = 72
÷11.25 ÷11.25 (Divide by "11.25" to get the variable by itself)
d = 6.4
Since, she only gets 1 pay per day, Ms. Masi will have to wait til her 7th day to pay her brother back.
Hope this Helps! :)

2x+27+x+27=180
3x+54=180
3x=180-54
x=126/3
x=42
angle B=x+27
=42+27
=69 degree
Step-by-step explanation:
Answer:
B=69
Step-by-step explanation:
Supplementary angles have a sum of 180. Set up your formula as
180=(2x+27)+(x+27)
180=2x+27+x+27
180-27-27=3x
126=3x
126/3=x
42=x
Now substitute 42 in place of x for Angle B
Angle B = x+27
B = 42+27
B=69
Check your work by doing the same for Angle A
Angle A = (2x+27)
A=2*42+27
A=84+27
A=111
Now add both together and if you did it right, your answer is 180
69+111 = 180
laura has a 3-digit combination lock on her briefcase and has forgtten the combination. If she knows that the first digit is a 3, and the second digit is a prime, how many numbers must Laura try before the lock is sure to open?
Answers
Answer:
Laura needs to try 36 more times before the lock is sure to open.
Step-by-step explanation:
Alright, with a three digit lock, there are 9 possible numbers for each digit:
1, 2, 3, 4, 5, 6, 7, 8, and 9.
Since the first one is 3, lets move onto the second digit, which is prime.
Of the numbers between 1-9,
2, 3, 5, and 7 are prime.
With the last digit, it can be any number 1-9.
With all of this, there are 4 combos left for the second digit then 9 combos for the third digit. Therefore, there would be 36 possible combinations as 4 * 9 =36.

========================================================
Work Shown:
p = number of items sold
855 = cost per item
855p = total revenue = total amount of money earned
6780 = total expenses
profit = revenue - expenses = 855p - 6780
profit = 855p - 6780
------------------
Now plug in p = 250
profit = 855p - 6780
profit = 855*250 - 6780
profit = 213,750 - 6,780
profit = 206,970 dollars
This is the profit the company makes in one month if p = 250 items are sold.
The CEO earns 15% of this profit, so,
15% of 206,970 = 0.15*(206,970) = 31,045.50
