Brody had his computer repaired at Store A. His bill was:
Initial Repair Cost = $1,200
Sales Tax of 6 percent = $72.00
Gratuity of 15 percent
Explain how you would calculate the gratuity for the services provided.
HELPPPPP
Answer:
1200 x 15%= $180.00
you don't need to add Gratuity on the Sales Tax
Step-by-step explanation:
Answer:
Add the repair cost and tax to get the total amount. Then multiply the total amount by 0.15 to find the gratuity.
The count in a bacteria culture was 800 after 15 minutes and 1200 after 40 minutes. Assuming the count grows exponentially,
What was the initial size of the culture?
Answer:1) bacteria size = b(initial) * e^(r * t)
initial size = 300
final size = 1600.
Substituting the values into the main equation:
1600 = 300 * e^(r * 35 - 20)
solving for 'r'.
1600 = 300 * e^(r * 15)
1600/300 = e^(r * 15)
taking natural log on both sides to eliminate the power
ln(16/3) = ln[e^(r * 15)]
ln(16/3) = r * 15
r = ln(16/3) / 15
= 0.11159843
= 11.16%
To find the initial bacteria size,
Given: t = 20
300 = b * e^(0.1116 * 20)
Solving for b:
300 = b * e^2.232
b = 300/e^2.232
b = 32

What is the slope and y-intercept of this equation?

A. m = -3 b =-8
B. m = -4 b = -3
C. m = 4 b =3
D. m = 3 b =4
Answer:

6*3=18 - 3/18=6
3*8=24 - 24/3=8
3*5=15 - 15/3=5

In how many distinguishable ways can you arrange the letters in the word CONNECTICUT? *
Answer:
The number of distinguishable arrangements are 1,663,200.
Step-by-step explanation:
The word is: CONNECTICUT
The number of ways to arrange a word when no conditions are applied is:
[tex]\frac{n!}{k_{1}!\cdot k_{2}!\cdot k_{3}!...\cdot k_{n}!}[/tex]
Here k is the number of times a word is repeated.
In the word CONNECTICUT there are:
3 Cs
2 Ns
2 Ts
And there are a total of n = 11 letters
So, the number of distinguishable arrangements are:
[tex]\frac{n!}{k_{1}!\cdot k_{2}!\cdot k_{3}!...\cdot k_{n}!}=\frac{11!}{3!\times 2!\times 2!}[/tex]
[tex]=\frac{39916800}{6\times 2\times 2}\\\\=1663200[/tex]
Thus, the number of distinguishable arrangements are 1,663,200.
write the slope-intercept form of the equation of the line through (4,-5) perpendicular to 6x + 12y=13
Answer:
y=2x-13
Step-by-step explanation:
12y=-6x+13
y=-1/2x+13/2 is the line, so to find the line perpendicular to that, you find that the slope of the line perpendicular to it is 2 because it's the negative reciprocal of -1/2. Then multiply 2 and 4 to get 8 and subtract 13 to get -5. Now you know that -13 is the y-intercept.

What is the mystery number?
• The mystery number is
PLEASE HELP ME!!!
The mystery number is 20 for the given information.
What is Number system?A number system is defined as a system of writing to express numbers.
To find the mystery number, we need to find a number that satisfies all the given conditions:
The GCF of 18, 36, and the mystery number is 2.
The prime factorization of 18 is 2 x 3 x 3.
The prime factorization of 36 is 2 x 2 x 3 x 3.
The only common factor is 2 x 3 x 3, which is equal to 18.
This means that the mystery number must also be divisible by 2.
The mystery number is a multiple of 5.
Since the mystery number is a multiple of 5 and also divisible by 2, it must end in 0 or 5.
The mystery number is greater than 18 and less than 30.
The only number that satisfies all three conditions is 20.
Hence, the mystery number is 20 for the given information.

Make up a word problem or scenario that uses the equation 7p+10=24. Make sure to elaborate as much as possible.
Given:
The equation is [tex]7p+10=24[/tex].
To find:
The scenario that uses the given equation.
Solution:
If p is the price of a good. Initial supply of goods at price 0 is 10 and supply increasing by 7 units if the price increased by 1 unit, then at what price the supply will be 24 units.
According to this scenario,
Total supply = 10+7p
Equate total supply with 24, to find the price at which the supply will be 24 units.
[tex]7p+10=24[/tex]
Therefore, the required scenario is "If p is the price of a good. Initial supply of goods at price 0 is 10 and supply increasing by 7 units if the price increased by 1 unit, then at what price the supply will be 24 units."

One of Camille’s graduation gifts is a trip on Amtrak from his home in Atlanta to New York to visit a cousin. Camille is afraid he may experience motion sickness so he has decided to take 50 mg of dimenhydrinate (which will help prevent motion sickness) before boarding Amtrak. Suppose that 85% of this medication remains in the bloodstream after 1 hour. Represent the amount of dimenhydrinate in Camille’s bloodstream for the first 4 hours of taking the drug. Let t be the number of hours after reaching its peak level of 50 mg. Explain how you determined the amount of dimenhydrinate in Camille’s bloodstream.
Answer:
26.10 mgStep-by-step explanation:
Initial amount of drug = 50 mgRemains after each hour = 85%Time = tThis relationship can be shown as a function:
y(t) = 50(0.85)^tAfter 4 hours remaining drug in blood:
y(4) = 50(0.85)^4 = 50(0.522) = 26.10 mgI NEED HELP ASAP!!!!

In a rectangle diagonal is 5cm ,breadth is 3cm .find the area and perimeter of the rectangle? (STEP BY STEP EXPLANATION)
Answer:
The area of rectangle is 12cm² and the perimeter is 14cm.
Step-by-step explanation:
First, you have to find the length of the rectangle using Pythagoras Theorem :
a² + b² = c²
a² + 3² = 5²
a² = 5² - 3²
a² = 16
a = √16
a = 4 cm
Next, you have to find the perimeter and area of rectangle :
Perimeter = 2(length + breadth)
P = 2(4 + 3)
P = 2(7)
P = 14 cm
Area = length×breadth
A = 4×3
A = 12 cm²
