the population of a town is represented by the formula p(t)=A(1.2)^t where A is the current population and t is time. determine to the nearest tenth of a year how long would it take the population to reach 5000 people if the current population is 3750
Answers
The equation using our information would be:
[tex]5000=3750(1.2)^t[/tex]
We would first divide both sides by 3750:
[tex]\frac{5000}{3750}=\frac{3750(1.2)^t}{3750} \\ \\ \frac{4}{3}=1.2^t [/tex]
To solve for the exponent, we use logarithms:
[tex]\log_{1.2}(\frac{4}{3})=t \\ \\1.57788=t \\1.6 \approx t[/tex]
the volume of a cone is 36π cubic units. What is the volume of a cylinder that has the same base area and the same height?
Answers
V_cylinder = pi*r^2*h
If you multiply the cone's volume by 3 then you get the cylinder's volume. They become the same formula
3 V_cone = pi r^2 h
Since the cone's volume is 36pi They cylinder's volume is 3*36pi = 108 pi
Final answer:
The volume of a cylinder with the same base and height as a given cone is three times the volume of the cone, so if the cone's volume is 36π cubic units, the cylinder's volume would be 108π cubic units.
Explanation:
The question involves finding the volume of a cylinder when the volume of a cone with identical base and height is given. Since the volume of a cone is one-third the volume of a cylinder with the same base area and height, we can find the volume of the cylinder by using the formula for the volume of a cylinder, V = πr²h, and multiplying the given cone's volume by 3. Therefore, if the volume of the cone is 36π cubic units, the volume of the cylinder would be 108π cubic units, because the volume of the cone is exactly one-third of the volume of a cylinder.
how do you find the least common multiple of 16 and 42?
Answers
To find the LCM of 16 and 42, we need to see what numbers can be divided by both 16 and 42 and so on.
16 ÷ 2 = 8
42 ÷ 2 = 21
Now, we multiply the results.
2 × 8 × 21 = 2 × 168 = 336

Answers
SEE ATTACHED IMAGE.
For this case what you should know is that the area of a circle is given by:
A = pi * r ^ 2
Where,
r: radio
On the other hand we have:
r = d / 2
Where,
d: diameter.
Substituting:
A = pi * (d / 2) ^ 2
We note that the diameter of the circle is 58 ft
Substituting:
A = 3.14 * (58/2) ^ 2
A = 2640.74 feet ^ 2
Answer:
The area of the entire circular region (including the flowerbed) is:
2,640.74 ft 2

Noah and his friends are going to an amusement park. The total cost of admission for 8 students is $100, and all students share the cost equally. Noah brought $13 for his ticket. Did he bring enough money to get into the park explain you reasoning.
Answers
Answer:
The correct answer is yes, he brought enough money to get into the park.
Step-by-step explanation:
Well, let's analyze the information provided:
Admission to the amusement park for 8 students is $ 100. If each student agreed to share of cost equally, it means that we must divide those 100, for each of those students.
Therefore it will remain 100/8 = 12.5
If each student must pay 12.5, and Noah brought $ 13, that means he will have enough money to enter the park, and he will even have $ 0.50 left over.
Peach juice and mango juice were mixed in a ratio of 6 to 4 to make tropical punch. A tape diagram representing the ratio of peach juice to mango juice is shown
Answers
because 6/4 can be reduced to 3/2 by canceling two from the fraction.
The total quantity of the tropical punch in terms of cups is 60 units.
How to get the total quantityLet P represent the volume of peach juice and M represent the volume of mango juice in the tropical punch.
Given the ratio of Peach : Mango is 6:4, which simplifies to 3:2:
This can be mathematically represented as:
[tex]\( \frac{P}{M} = \frac{3}{2} \) or \( P = \frac{3}{2}M \)[/tex]
In this ratio:
- The volume of peach juice contributes 3 units out of a total of 5 units (3 units peach : 2 units mango) of the tropical punch.
- The volume of mango juice contributes 2 units out of a total of 5 units (3 units peach : 2 units mango) of the tropical punch.
1 unit of the mixture = 12 cups
Therefore, 5 units of the mixture = 5 * 12 = 60 cups
Hence, the total quantity of the tropical punch in terms of cups is 60 units.

Is rolling doubles a simple event or compound event? Explain.
Answers
is {1,2,3,4,5,6}
A simple event can be defined as a SINGLE outcome : Example getting a 3 OR 5 OR any other number from the sample space.
Now if you roll 1 dice & you want to get an even number (2,4,6) then you have chosen from the sample space 3 outcome & this is a compound event
Equally if you roll 2 dice and want to get "one" and/or "three" this is a compound event since you have chosen 2 outcome from the sample space.
Mind you, if you want 5 And 5 when rolling two dice it's a simple event because you have chosen ONE outcome from the sample space.

Today, the great Pyramid of Giza bear Cario, Eygpt, stands 137 meters tall, coming to a point . A base is a square with each side measuring 230 meters wide. What is the slope of the pyramid
Answers
The correct answer is [tex]1.191[/tex]
To find the slope of the pyramid, we need to calculate the ratio of the vertical change (height) to the horizontal change (half of the base length).
Given information:
- Height of the pyramid (vertical change) = 137 meters
- Base length of the pyramid = 230 meters
- The base of the pyramid is a square, so each side is 230 meters wide
Step 1: Calculate the horizontal change, which is half of the base length.
Horizontal change = [tex]\frac{1}{2} \times Base length[/tex]
Horizontal change = [tex]\frac{1}{2} \times 230 meters[/tex]
Horizontal change = 115 meters
Step 2: Calculate the slope by dividing the vertical change (height) by the horizontal change.
Slope =[tex]\frac{\text{Vertical change}}{\text{Horizontal change}}[/tex]
Slope = [tex]\frac{137}{115}[/tex]
Slope = [tex]{1.191}[/tex]
Therefore, the slope of the pyramid is 1.191.

A bag contains 30 red and blue marbles identical in size. Jason randomly selected 1 marble, recorded its color, and replaced it. He repeated this process 10 times and drew 6 red marbles and 4 blue marbles. Which of the following statements is MOST likely true about the marbles in the bag?
The bag contains 16 red marbles and 14 blue marbles.
The bag contains 12 red marbles and 18 blue marbles.
The bag contains 18 red marbles and 12 blue marbles.
The bag contains 15 red marbles and 15 blue marbles.
Answers
Final answer:
The bag is most likely to contain 16 red marbles and 14 blue marbles due to the probabilities obtained from multiple draws that is option A is correct.
Explanation:
The bag contains 16 red marbles and 14 blue marbles.
For the first draw, the probability of selecting a red marble is 30/60 = 1/2.
Since the marbles are replaced, the probability remains the same for each draw.
Thus, the proportions suggest that the bag has more red marbles than blue marbles.
Adiya said that the first step to solving the quadratic equation x2 + 6 = 20x by completing the square was to divide 6 by 2, square that value, and add the result to both sides. Is Adiya’s solution method correct? Explain.
Answers
Thus, Adiya's approach is incorrect. The constant needs to be isolated solely on a single side of the equation in order to construct a perfect square trinomial.
Explain about the method of completing square:Mathematicians employ the "completing the square" technique to change a quadratic expression of the type ax² + bx + c into the vertex form a(x + m)² + n. The quadratic equation can be solved using this method most frequently by rearranging that expression acquired after the square has been completed.Given condition-
Adiya explained that the first step to completing the square and finding the solution to the quadratic equation x² + 6 = 20x was to divide 6 by 2, square that number, and then add the answer to both sides.
Adiya's approach is incorrect.
The constant needs to be isolated solely on a single side of the equation in order to construct a perfect square trinomial. The constant in the perfect square trinomial is also found using the coefficient of the term with an exponent of 1. The 20x term needs to be placed on the exact same side of the formula as x², according to Adiya. Then multiply 20 by 2 to get a square, add 100 to each sides.Correct method:
x² + 6 = 20x
x² - 20x - 6 = 0
x² - 2*10x - 6 = 0
x² - 2*10x - 6 + 100 - 100 = 0
x² - 2*10x + 100 - 6 - 100 = 0
(x - 10)² - 94 = 0
(x - 10)² = 94
Thus, Adiya's approach is incorrect. The constant needs to be isolated solely on a single side of the equation in order to construct a perfect square trinomial.
