To determine the wall space needed for Mr. Hart's picture, calculate the area of the rectangle formed by the picture's dimensions: length (13 inches) times width (9 inches), resulting in 117 square inches of wall space.
The student's question about Mr. Hart hanging a picture on a wall involves calculating the wall space the picture will occupy. This is essentially a question about finding the area of a rectangle. To find the area, one must multiply the length by the width of the rectangle. In this case, the length of the picture frame is 13 inches and the width is 9 inches. The calculation will be:
Area = Length × Width
Area = 13 inches × 9 inches
Area = 117 square inches
Therefore, the picture will need 117 square inches of wall space.

One circle has a circumference half as large as that of a second circle what ratio compares the diameter of the first circle
The diameter of first circle is half of the second one.
What is a circle?A circle is a geometric shape, all of which points are equidistant from a fixed point called as the Centre. The centre of the circle does not lie on it. The tangents drawn from the same point outside a circle are equal in length.
The given problem can be solved as follows,
The circumference of a circle is given as C = πd where d is the diameter of the circle.
Suppose, the circumference and diameters for both the circles are C₁, d₁ and C₂,d₂ respectively.
Now, the expression for circumference can be written as,
C₁ = πd₁
And, C₂ = πd₂
As per the question C₁ = 1/2C₂, then the following equations can be written as,
πd₁ = 1/2πd₂
⇒ d₁ = 1/2d₂
Hence, the diameters of the two circles are also in the same ratio.

sam had four test last month his scores were 81 94 83 and 91 what is the median of his scores
Final answer:
The median of Sam's test scores (81, 83, 91, 94) is 87, calculated by averaging the two middle numbers after arranging the scores in ascending order.
Explanation:
To find the median of Sam's test scores, we first list the scores in numerical order: 81, 83, 91, 94. Since there are an even number of scores, the median will be the average of the two middle numbers, which are 83 and 91. To find the median, you add those two middle scores and divide by 2: (83 + 91) / 2 = 174 / 2 = 87. Therefore, the median of Sam's scores is 87.
Calculating the median of a set of values involves organizing them in ascending order, as done with Sam's test scores. In cases where there is an even number of values, the median is determined by averaging the two middle numbers. This method ensures a representative central value for the dataset, providing insight into the typical test performance. In Sam's case, with test scores 81, 83, 91, and 94, the median is computed as 87, offering a balanced perspective on his overall performance.
Find the mean, median, and interquartile for the data set below. Round your answer to the nearest tenth. 27,16,8,5,19,14,22,31,13,5,23,16,8 Mean: Median: Interquartile range:
The mean of the data set is 15.9, the median is 16, and the interquartile range is 14.5 after rounding to the nearest tenth.
To find the mean, median, and interquartile range for the data set 27, 16, 8, 5, 19, 14, 22, 31, 13, 5, 23, 16, 8, we need to follow these steps:
Organize the data in ascending order: 5, 5, 8, 8, 13, 14, 16, 16, 19, 22, 23, 27, 31.
Calculate the mean by adding all numbers and divide by the total count. Mean: (5+5+8+8+13+14+16+16+19+22+23+27+31)/13 = 207/13 ≈ 15.9.
Find the median which is the middle number. Since there are 13 values, the median is the 7th number: Median: 16.
For the first quartile (Q1) and third quartile (Q3), divide the list into two halves. The Q1 is the median of the first half, and Q3 is the median of the second half. Q1: Median of 5, 5, 8, 8, 13, 14 ≈ 8.5; Q3: Median of 19, 22, 23, 27, 31 ≈ 23.
Calculate the interquartile range (IQR) by subtracting Q1 from Q3. Interquartile range: IQR = Q3 - Q1 = 23 - 8.5 = 14.5.
The mean is approximately 15.9, the median is 16, and the interquartile range is 14.5.
Mary has 7 1/4 yard of fabric. she cuts off 3/4 foot fabric to make the edge even. Mary wants to end up with 3 pieces of fabric that are the same size. how long will each piece be?
Final answer:
Mary has 7 1/4 yards of fabric, and after cutting off 3/4 foot (which is 1/4 yard), she is left with 7 yards. When she divides this equally into 3 pieces, each piece will be 2 1/3 yards long.
Explanation:
Mary has 7 1/4 yards of fabric. To convert the fabric she cuts off, which is 3/4 foot, to yards, we use the fact that 1 yard = 3 feet. Thus, 3/4 foot is 1/4 yard. After cutting off 1/4 yard from her fabric, she is left with 7 yards (7 1/4 yards - 1/4 yard). Mary wants to divide this into 3 equal pieces. To find the length of each piece, we divide 7 yards by 3, which is 2 1/3 yards for each piece.

in a certain area of Brazil, deforestation is currently the most critical Socio economic problem. The area of a certain rain forest is currently 1156.25 square miles. after every year, the area of this rain force decreases by 2% which of the following statements is correct
A- deforestation problem is an example of exponential growth
B- The growth or decay rate for the area of the rainforest is 0.2
C- The function of equals 1156.25(1 -0.02 )^t
D- in less than a century the rain forest will be completely wiped out
E- in about 35 years the area of the rain forest will be cut by more than half
F-The domain of the function that model the deforestation problem above is 0<_t<_100 (less than or equal to <_)
A is INCORRECT because here we have degrowth and growth
B is INCORRECT because the decay factor is 2% or 0.02 , not 0.2
C is CORRECT, the function is which is used to calculated the area of rainforest at time t is given by 1156.25(1 -0.02 )^t
D is INCORRECT, if we plug in t=100 in the above equation , we get = 1156*(1-0.02)^100 = 153 square miles of forest. So it will not be wiped out
E is CORRECT, if we plug in t =35, we get = 1156*(1-0.02)^35 = 570 square miles. So more than half will be cut in 35 years
F is INCORRECT becuase domain goes beyond 100 years as shown by option D
So, correct options are C and E
Find the center, vertices, and foci of the ellipse with equation 2x2 + 9y2 = 18.
Find the quotient of -36x^3-6x^2+12x/-6x
Answer:
6x² + x - 2
Explanation:
To find the quotient of a polynomial expression divided by a monomial, divide each term by the monomial.
[tex]\frac{-36x^3-6x^2 + 12x}{-6x}[/tex] becomes [tex]\frac{-36x^3}{-6x} + \frac{(-6x^2)}{(-6x)} + \frac{12x}{(-6x)}[/tex]
-36x³ / (-6x) = 6x²
(-6x²) / (-6x) = 1x = x
12x / -6x = -2
Place each of these terms together into an polynomial expression once more and the quotient is: 6x² + x - 2

Whst is the remainder when f(x)=x^3+3x^2-10x-4 is diveded by x-3
The remainder when the polynomial [tex]f(x)=x^3+3x^2-10x-4[/tex] is divided by x-3 is found using the Remainder Theorem and is 20.
The remainder when a polynomial f(x) is divided by a linear divisor such as x - 3 can be found using the Remainder Theorem, which states that the remainder is simply f(3). To find the remainder for [tex]f(x)=x^3+3x^2-10x-4[/tex], we substitute x = 3 into the polynomial.
Calculate f(3):
[tex]f(3) = (3)^3 + 3*(3)^2 - 10*(3) - 4[/tex]
f(3) = 27 + 27 - 30 - 4
f(3) = 54 - 34
f(3) = 20
Therefore, the remainder when f(x) is divided by x - 3 is 20.
