You put $400 in an account. The account earns $18 simple interest in 9 months. What is the annual interest rate?
Answer:
6%
Step-by-step explanation:
Let's start by finding the amount earned per month:
[tex]\frac{18}{9}[/tex]=2
Now let's find the % per month
[tex]\frac{2}{400} =.005[/tex], or .5%
Now let's multiply by 12 months to get the annual interest rate
[tex].005 * 12 = .06[/tex] or 6%

wanda rode her bike 21/10 miles. Which mixed number shows how far Wanda rode her bike?
To convert the improper fraction 21/10 to a mixed number, divide 21 by 10 to get 2 with a remainder of 1. The mixed number is 2 1/10.
The student is asking for help converting an improper fraction to a mixed number. An improper fraction is one where the numerator is greater than the denominator. To convert 21/10 to a mixed number, we divide the numerator by the denominator.
Divide 21 by 10, which equals 2 with a remainder of 1.
The whole number part of the mixed number is the quotient, which is 2.
The remainder becomes the new numerator, and the original denominator stays the same, making it 1/10.
Therefore, the mixed number is 2 1/10.

the number of bacteria in a container increases at the rate of R(t) bacteria per hour. If there are 1000 bacteria at time t=0 , which of the following expressions gives the number of bacteria in the container at time t=3 hours?
The expression for the total number of bacteria at t = 3 hours, given an initial 1000 bacteria at t = 0, is: [tex]\[ 1000 + \int_0^3 R(x) \, dx \][/tex]
To find the number of bacteria in the container at time t = 3 hours, given that the rate of increase is [tex]\( R(t) \)[/tex] bacteria per hour and there are 1000 bacteria at time t = 0, you can use the following steps:
Start with the initial condition :
You are given that there are 1000 bacteria at t = 0.
So, the initial condition is [tex]\( N(0) = 1000 \),[/tex] where N(t) represents the total number of bacteria at time t.
Integrate to find the change in number of bacteria over time :
Since the rate of increase is R(t), the total increase in bacteria from time t = 0 to t = t is given by integrating R(t) with respect to time.
This integral provides the cumulative increase in bacteria:
[tex]\[ \int_0^t R(x) \, dx. \][/tex]
Add the initial bacteria to the increase :
Since there are already 1000 bacteria at t = 0, the total number of bacteria at time t is given by:
[tex]\[ N(t) = 1000 + \int_0^t R(x) \, dx. \][/tex]
Find the expression for t = 3 hours :
To find the total number of bacteria at t = 3 hours, you substitute t = 3 into the expression derived in step 3:
[tex]\[ N(3) = 1000 + \int_0^3 R(x) \, dx. \][/tex]
Thus, the expression [tex]\( 1000 + \int_0^3 R(x) \, dx \)[/tex] gives the number of bacteria in the container at time t = 3 hours.
Question :
the number of bacteria in a container increases at the rate of R(t) bacteria per hour. If there are 1000 bacteria at time t=0 , which of the following expressions gives the number of bacteria in the container at time t=3 hours?
The correct expression that gives the number of bacteria in the container at time t = 3 hours is D. [tex]1000 + \int_0^3 R(t) \, dt[/tex]
The problem asks us to find the number of bacteria in a container at t = 3 hours, given that the number of bacteria increases at a rate of R(t) bacteria per hour and there are 1000 bacteria at time t = 0.
To solve this, we need to integrate the rate function R(t) to find the total change in the number of bacteria over the interval from t = 0 to t = 3.
1. Initial number of bacteria:
At t = 0, the number of bacteria is 1000.
2. Change in number of bacteria:
The rate of change of the number of bacteria is given by R(t) bacteria per hour.
To find the total number of bacteria added over the time interval from t = 0 to t = 3, we need to integrate R(t) from 0 to 3.
Total change in number of bacteria = [tex]\int_0^3 R(t) \, dt[/tex]
3. Total number of bacteria at t = 3 hours:
This is the sum of the initial number of bacteria and the total change in the number of bacteria over the 3 hours.
Number of bacteria at t = 3 hours = [tex]1000 + \int_0^3 R(t) \, dt[/tex]
Complete Question:
The number of bacteria in a container increases at the rate of R(t) bacteria per hour. If there are 1000 bacteria at time t=0, which of the following expressions gives the number of bacteria in the container at time t=3 hours?
(A) R(3)
(B) 1000+R(3)
(C) [tex]$\int_0^3 R(t) d t$[/tex]
(D) [tex]$1000+\int_0^3 R(t) d t$[/tex]

for her bedroom Marisol is buying a rug that is 6 feet by 8 feet her room is 9 feet by 11 feet how many square feet of floor will not be covered by Rug?
Final answer:
Marisol's bedroom is 99 square feet, and the rug area is 48 square feet. By subtracting the rug area from the total room area, we find that 51 square feet of floor will not be covered by the rug.
Explanation:
To find out how many square feet of Marisol's bedroom floor will not be covered by the rug, we must first calculate the area of her entire room and then the area of the rug. The area of a rectangle is found by multiplying the length by the width. The area of Marisol's room is 9 feet × 11 feet = 99 square feet. The area of the rug is 6 feet × 8 feet = 48 square feet.
Next, we subtract the area of the rug from the area of the entire room to find the uncovered floor area.
Uncovered floor area = Total room area – Rug area
= 99 square feet – 48 square feet
= 51 square feet
Therefore, 51 square feet of Marisol's bedroom floor will not be covered by the rug.
Question 19 find the solution
An item is called "price elastic" if you drop the price and revenue goes up. Last week you sold 10 sodas for $2 each; this week you sold 30 sodas for $1 each. Is soda price elastic?
Final answer:
Soda is price elastic because lowering the price from $2 to $1 resulted in an increase in total revenue from $20 to $30, indicating that a decrease in price caused a larger increase in quantity sold.
Explanation:
When determining whether an item is price elastic or not, we look at the effect that changing the price has on the total revenue. If a decrease in price leads to an increase in total revenue, the demand for the product is considered price elastic. In the example given, soda was sold at different prices and quantities: 10 sodas at $2 each last week, and 30 sodas at $1 this week. We use these numbers to calculate the total revenue for each week:
Last week: 10 sodas × $2/soda = $20
This week: 30 sodas × $1/soda = $30
Since the total revenue increased from $20 to $30 when the price was lowered from $2 to $1, we can see that the revenue increased as a result of the price drop, indicating that the demand for soda is indeed price elastic.

A book club offers a choice of 8 books from a list of 40. In how many can a member make a collection?
This is a math combination problem. The number of ways a member can choose 8 books from a list of 40 is 76,904,685 ways.
Explanation:This is a combinatorics problem, specifically a combination problem. A combination is a selection of items from a larger set where the order does not matter. In this case, we have a set of 40 books and want to know how many ways one can select 8 books from those 40. The formula for calculating combinations is nCr = n! / [(n - r)! * r!] where 'n' represents the total number of items, 'r' represents the number of items to choose, 'nCr' represents the number of combinations of n items taken r at a time, and '!' denotes factorial, the product of all positive integers up to that number.
Applying the combination formula, a member can make the choice of 8 books from a list of 40 in:
40C8 = 40! / [(40 - 8)! * 8!] = 76,904,685 ways

Polygon ABCDEF is the result of a translation of polygon GHIJKL . GL¯¯¯¯¯ is parallel to HI¯¯¯¯¯ in the pre-image. please help
GL parallel to HI in the pre-image ensures AB remains parallel to FE in the translation.
Given that GL and HI are parallel, we can infer that AB and FE will also remain parallel in the translation. The parallelism of lines GL and HI suggests that their corresponding sides, AB and FE, will exhibit the same parallel relationship during the translation process. This is a consequence of the consistent geometric transformation applied to all points on lines GL and HI. As each point on GL undergoes translation, its corresponding point on HI experiences the same displacement, preserving the parallelism.
Therefore, we can confidently state that AB and FE maintain their parallel orientation, aligning with the geometric properties of the translation that preserves parallel lines. The parallelism observed in the original configuration persists throughout the translation, ensuring that AB and FE remain parallel to each other.
