. The width of a rectangle is 16 feet less than 3 times the length. If the area is 35 square feet, find
the dimensions of the rectangle.
The dimensions of the rectangle are approximately 8.93 feet for the length and 10.8 feet for the width. This solution involves setting up and solving a quadratic equation based on the given conditions.
Explanation:The subject of this question is Mathematics and it requires algebraic reasoning to solve. Here's step-by-step how to find the dimensions of the rectangle:
Let the length be denoted by 'x' (in feet).According to the question, the width is 16 feet less than three times the length, which can be written algebraically as '3x - 16'.The area of a rectangle is calculated by length times width, so in this example we would multiply 'x' by '3x - 16', and set that equal to the total area of 35 square feet.This set-up results in the equation 'x(3x - 16) = 35' or '3x^2 - 16x - 35 = 0'.Solving this quadratic equation for 'x', we find that the length (x) is approximately 8.93 feet.Substituting this value back into the equation for width, we find that the width is approximately 10.8 feet.Learn more about Solving Quadratic Equations here:https://brainly.com/question/30398551

PLEASE HELP A paperweight in the shape of a rectangular prism is shown: A right rectangular prism is shown with length 10 cm, width 4 cm, and height 4 cm. If a cross section of the paperweight is cut perpendicular to the base, which shape describes the cross section? Parallelogram Triangle Square Hexagon
Answer: Square
Step-by-step explanation:
Since, the dimension of the given rectangular prism is 10 × 4 × 4
If a cross section of the paperweight is cut perpendicular to the base,
Then the dimension of the resultant quadrilateral is, 4 × 4
That is, the length and breadth is equal,
And the angles are of 90° each,
Which is the condition of a square,
Therefore, the resultant shape will be square.
⇒ Third Option is correct.
The cross section of the paperweight when cut perpendicularly to the base is a square.
Given the following data:
Length of rectangular prism = 10 cm.Width of rectangular prism = 4 cm.Height of rectangular prism = 4 cm.How to determine the resultant shape.We know that the shape of this paperweight is a right rectangular prism. Also, the base area of the paperweight is cut perpendicularly.
This ultimately implies that, the paperweight's length would be removed while its height and width remains, which corresponds to the dimensions (length and width) of a four-shaped object or quadrilateral with an angle of 90 degrees each.
In conclusion, the cross section of the paperweight when cut perpendicularly to the base is a square.

A cell phone plan has a monthly cost that is shown in the table below. What is the correct statement regarding the average rate of change during the 40-minute time of talk? Total minutes of talk time Monthly cost of cell phone 0 $9.95 10 $10.65 20 $11.35 30 $12.05 40 $12.75
Answer:
The correct statement regarding the average rate of change during the 40-minute time of talk is that the average rate of change of the monthly cost with respect to the talk time is $0.07 per minute.
Explanation:
To find the average rate of change during the 40-minute time of talk, we can calculate the average rate of change of the cost with respect to the number of minutes of talk time.
We can use the formula for average rate of change, which is:
[tex]\[ \text{Average rate of change} = \frac{\text{Change in cost}}{\text{Change in talk time}} \][/tex]
Given the following data:
- At 0 minutes of talk time, the monthly cost is $9.95.
- At 40 minutes of talk time, the monthly cost is $12.75.
Using the formula, we can calculate the average rate of change:
[tex]\[ \text{Change in cost} = 12.75 - 9.95 = 2.80 \][/tex]
[tex]\[ \text{Change in talk time} = 40 - 0 = 40 \][/tex]
[tex]\[ \text{Average rate of change} = \frac{2.80}{40} = 0.07 \][/tex]

After a 85% reduction, you purchase a new soft drink machine for $90. What was the original price?
The original price of the soft drink machine was $600, obtained by using the percentage reduction formula to find that $90 represents 15% of the original price.
Explanation:To find the original price of the soft drink machine before the 85% reduction, we first need to understand what a percentage reduction means. An 85% reduction implies that the final price is only 15% of the original price, as 100% - 85% = 15%. Therefore, the $90 you paid is 15% of the original price.
Next, we will step through the following calculation to determine the original price:
Let the original price be represented by P.15% of P is equal to $90, which can be written as (15/100) × P = $90.To find P, we divide both sides of the equation by 15 and then multiply by 100 to isolate P on one side. This gives us P = (90 ÷ 15) × 100.Performing the calculation P = 6 × 100, we find that P = $600.Therefore, the original price of the soft drink machine was $600.
Using the numbers 3, 5, and 8, can you write nine proper fractions and nine improper fractions? You may use each number only once within a fraction.
Answer: yes we can write nine proper and nine improper fraction with help of these given numbers.
Explanation: Since, a proper fraction is a fraction which has the value less than 1, that is, the value of numerator is less than the value of denominator.
For example p/q is a proper fraction if p<q.
On the other hand, In Improper fraction numerator is greater than denominator.
Since, given numbers are 3,5 and 8
So, the possible proper fractions= [tex]\frac{3}{5},\frac{3}{8} \frac{5}{8},\frac{3}{5.8},\frac{5}{3.8}, \frac{8}{5.3},\frac{3}{5+8},\frac{5}{3+8}, \frac{5-3}{8}[/tex]⇒[tex]\frac{3}{5},\frac{3}{8} \frac{5}{8},\frac{3}{40},\frac{5}{24}, \frac{8}{15},\frac{3}{13},\frac{5}{11}, \frac{1}{4}[/tex]
Similarly, the possible improper fraction= [tex]\frac{5}{3},\frac{8}{3} \frac{8}{5},\frac{40}{3},\frac{24}{5}, \frac{15}{8},\frac{13}{3},\frac{11}{5}, \frac{19}{3}[/tex] ( Here, [tex]8-\frac{5}{3}=\frac{19}{3}[/tex] )

Suppose that 5 customers arrive, and each orders a different appetizer to share from a choice of 12 appetizers. In how many ways can this be done?
The number of ways to choose a different appetizer for each of the 5 customers from a choice of 12 appetizers is 95,040.
Explanation:The number of ways to choose a different appetizer for each of the 5 customers from a choice of 12 appetizers can be calculated using permutations. In this case, the order in which the appetizers are chosen does matter, and repetition is not allowed since each customer must choose a different appetizer.
To calculate the number of ways, we can use the formula for permutations:
P(n, r) = n! / (n-r)!
Where n is the total number of items and r is the number of items to be chosen.
So, in this case, the number of ways to choose the appetizers is:
P(12, 5) = 12! / (12-5)! = 12! / 7!
Using a calculator simplifies to:
P(12, 5) = 95,040
