Ernesto plans to build a pen for his pet iguana. Think about these two different questions. What is the area of the largest rectangular pen that he can make with 400 meters of fencing? What is the area of the largest circular pen he can make with the 400 meters of fencing?
Final answer:
Given 400 meters of fencing, constructing a square pen would result in an area of 10,000 square meters, while a circular pen would yield approximately 12,732 square meters, making the circular pen the larger option.
Explanation:
Ernesto wants to construct the largest possible pen for his iguana using 400 meters of fencing. To determine the maximum area of a rectangular pen, we can use the principle that a square will always provide the largest area for a given perimeter. In the case of a rectangular enclosure, we form a square with each side being one-fourth of the total available fencing, here being L/4 where L is 400 meters. Thus, each side of the square would be 400/4 = 100 meters. The area of such a square would be side × side = 100 m × 100 m = 10,000 square meters.
For the circular pen, the entire length of fencing would be the circumference of the circle. Given the formula for circumference is C = 2πr, where r is the radius, we set 400 = 2πr to solve for r, which is approximately 63.66 meters. The area of a circle is given by A = πr², which would then be approximately π(63.66)^2 ≈ 12,732 square meters. Therefore, a circular pen would provide a larger enclosed area compared to a square one given the same amount of fencing.

Miss Valens withdrew $525 from her savings account over a period of 14 days. Which ratio represents the daily change in her account balance?
(multi choice picture below)
It says that she withdrew 525 dollars from a saving account over a total period of 14 days.
As this amount is debited from her account, so it would be a negative number in her passbook i.e. -525 dollars.
To find the average change in the account balance, we can divide the total amount withdrawn from the account by the total number of days.
Average change in account balance = [tex]\frac{debited \;amount}{total \;time \;period}[/tex] .
Average change = [tex]\frac{-525}{14}[/tex]
Hence, option A is correct i.e. [tex]\frac{-525}{14}[/tex].

write the equation of the line that passes through the points (-2,3) and (-2,5)
Graph y+2 ≤ 1/4x-1 I GIVE BRAINLIEST
The shaded region represents the solution to the inequality y + 2 ≤ (1/4)x - 1. Graph A represent the inequality.
To graph the inequality y + 2 ≤ (1/4)x - 1, we need to first plot the corresponding boundary line, which is the equation y + 2 = (1/4)x - 1. Then, we'll determine the region of the graph that satisfies the inequality.
Step 1: Plot the boundary line:
To graph the line y + 2 = (1/4)x - 1, we'll first rewrite it in the slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.
y + 2 = (1/4)x - 1
Subtract 2 from both sides:
y = (1/4)x - 3
Now, we can see that the slope (m) is 1/4, and the y-intercept (b) is -3.
Step 2: Plot the y-intercept and use the slope to find additional points:
Plot the y-intercept, which is -3, on the graph. Then, use the slope (1/4) to find other points. The slope of 1/4 means that for every increase of 1 unit in the x-direction, y increases by 1/4 units.
Let's find a few more points:
- If x = 0, y = (1/4) * 0 - 3 = -3 (giving us another point on the line).
- If x = 4, y = (1/4) * 4 - 3 = -2 (giving us another point on the line).
- If x = -4, y = (1/4) * (-4) - 3 = -4 (giving us another point on the line).
Step 3: Connect the points to draw the line:
Now, draw a straight line passing through all the points you've plotted. The line represents the boundary of the inequality.
Step 4: Determine the region that satisfies the inequality:
Since the inequality is y + 2 ≤ (1/4)x - 1, we need to determine which side of the line satisfies this inequality. One way to do this is to pick a test point that is not on the line (like the origin (0,0)), and check if it satisfies the inequality.
For (0, 0):
0 + 2 ≤ (1/4) * 0 - 1
2 ≤ -1
Since 2 is not less than or equal to -1, the region containing the origin (0,0) does not satisfy the inequality. Thus, we shade the other side of the line.
Step 5: Shade the region that satisfies the inequality:
Shade the region on the graph that is below the line y + 2 = (1/4)x - 1. This shaded region represents the solution to the inequality y + 2 ≤ (1/4)x - 1.
Graph A represent the inequality.

expressions equivalent to 4 square root 5
How many outcomes are there for the event of rolling a 6-sided number cube and then spinning a 4-part spinner?
Final answer:
To determine the total outcomes for a 6-sided die and a 4-part spinner, simply multiply the outcomes for each, resulting in 24 unique outcomes.
Explanation:
When calculating the number of outcomes for rolling a 6-sided die and then spinning a 4-part spinner, we need to consider the principle of counting. The die has six possible outcomes: 1, 2, 3, 4, 5, and 6. The spinner has four possible outcomes.
To find the total number of combined outcomes, we multiply the number of outcomes of the die by the number of outcomes of the spinner. Therefore, the total number of outcomes is 6 (from the die) times 4 (from the spinner) which equals 24 unique outcomes.

Evaluate the expression. Write your answer in scientific notation. (9×10^−3)+(2.4×10^−5)÷0.0012
The given expression (9×10^−3)+(2.4×10^−5)÷0.0012 equals 2.9x10^-2 in scientific notation. The division operation was performed first and added to 9x10^-3, demonstrating the usefulness of scientific notation in simplifying arithmetic.
Explanation:In order to evaluate the given expression (9×10^−3)+(2.4×10^−5)÷0.0012, you first need to perform the operations in parentheses which is the standard form of the expression to simplify it. Next, we must remember the order of mathematical operations, also known as BIDMAS or PEMDAS in mathematics: Brackets (or Parentheses), Indices (or Exponents), Division, Multiplication, Addition, and Subtraction.
However, in this expression we only have addition and a division to perform. The division operation takes precedence over addition, thus we first divide 2.4×10^−5 by 0.0012. The result of this can then be added to 9×10^−3. Let's perform these calculations:
2.4×10^−5 ÷ 0.0012 = 2×10^−2(9×10^−3)+(2×10^−2)= 0.029 or 2.9x10^-2 in scientific notationSo, the evaluated expression equals 2.9x10^-2 in scientific notation. This is a simplification of arithmetic using scientific notation, which helps to easily handle very large or very small numbers.

Trisha noticed that three copies of a certain triangle could be arranged in a way that the three angles of the triangle form a straight line. what can she conclude from this observation
a. that each interior angle of the triangle must measure 60*
b.exterior must measure 60*
c.sum of interior angles must be 180*
d.sum of exterior angles must be 180*
show work please and i need it desperately
Trisha's observation that three copies of a certain triangle can be arranged to form a straight line suggests that each interior angle of the triangle measures 60 degrees. This is because a straight line measures 180 degrees, which implies that the sum of the three angles is 180 degrees. Therefore, each angle must measure 60 degrees.
Explanation:In this case, Trisha was able to arrange three copies of the triangle in such a way that their angles form a straight line. That straight line, or 180 degrees, is, in fact, the sum of all interior angles in a triangle. Hence, it can be inferred that the sum of the angles of each triangle she had must be 60 degrees, implying that each triangle is an equilateral triangle. Therefore the correct answer is: a. each interior angle of the triangle must measure 60*.
Step-by-step explanation: If you consider a straight line, it measures 180 degrees. If Trisha's three triangles are forming such a line, it implies that the three angles are combining to give 180 degrees. Assuming each angle is the same (because they are copies of the same triangle), then each angle in the triangle is 60 degrees (since 180/3 = 60).

quick I need help quick Morgan rode her bike. 2 kilometers from her house to her friend's house from her friend's house she rode 600m in all going to and from the library then she rode back home how many meters did Morgan like in all
Morgan rode her bike a total of 4600 meters after combining the distances from her house to her friend's, to and from the library, and back to her house.
To determine how many meters Morgan cycled in total, we first need to convert all distances into the same unit. Morgan rode 2 kilometers from her house to her friend's house, which is equal to 2000 meters. Then, she rode 600 meters in total going to and from the library. Since she needs to return home, she would ride the initial 2000 meters back. Therefore, the total distance Morgan cycled is the sum of these three distances.
Calculation
Distance from home to friend's house: 2000 meters
Traveling to and from the library: 600 meters
Distance from friend's house back to home: 2000 meters
Adding these distances gives us the total distance Morgan rode:
Total Distance = 2000m + 600m + 2000m = 4600 meters.
