She should choose plan 1 because it is cheaper even in the long run.
plan 1: 34.99 x 12 = 419.88
plan 2: 134.97 x 4 = 539.88
-
419.88 < 539.88
Answer:
Work shown below!
Step-by-step explanation:
1 year = 12 months
Plan 1 = $34.99 per month
Plan 2 = $134.97 per 3 months
Plan 1: $34.99(12) = $419.88
Plan 2: $134.97(4) = $539.88
She would save $120 if she chooses Plan 1
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 mgSet 35 between Pat and Sam in the ratio 4:3 how much money will each person get

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

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."

Ana makes her own birdseed. She mixes 8 ounces of barley, 16 ounces of dried fruit, and 12 ounces of corn. How many pounds of bird seed does Ana make with this recipe?
Answer:
36
Step-by-step explanation:
If you add 8 to 12 you get 20 and then you add 16 to that 20 and then you get 36
8 + 12 = 20
20 + 16 = 36
36 ounces of bird seeds
How are corresponding side lengths of two similar figures related?
Answer:
If two objects have the same shape, they are called "similar." When two figures are similar, the ratios of the lengths of their corresponding sides are equal.
Step-by-step explanation:
Answer:
If two objects have the same shape, they are similar. If they are similar, the ratios of side lengths are equal. If the base of a rectangle was 22 feet and it was dilated by 2, the base would be 44 feet. The angle measures however, stay the same, or the two figures would not be similar.

Step-by-step explanation:
consider n proper fraction such that the numerator is 2 less than the denominator. If the numerator and denominator are each increased by 1, then the ratio of the numerator and denominator of the new fraction is 4:5. Determine the original fraction
the original fraction would be 4:5 divided by 2 and 1 making the answer clear and then what you do is take your answer multiplying it by the improper fraction and subtracting it by the mixed and the others that you should know and then you get your real answer.

Step-by-step explanation:
3*3=9 - 9/3=3
6*3=18 - 3/18=6

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

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.

In the equation y = x +2, x represents Jean's age in years, and y represents the age of Jean's older sister, Rachel. Which is the graph of this equation? (please help)
Answer:
C.
Step-by-step explanation:
The equation is already in y = mx + b format. M means slope and b means is the y-intercept. Since we can see the slope is 1 and the y-intercept is 2, we can find the graph that matches this. In graph C, the line intercepts the y axis at the point 2 and the line goes up 1 on the y axis for every 1 on the x axis so it is true.

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.
