Answer:
Area = 200ft²
Step-by-step explanation:
Perimeter of a rectangle = 2(length+width)
Area of a rectangle = length * width
Then:
g = 2w Eq. 1
60 = 2(g+w) Eq. 2
g = length
w = width
From Eq. 2
60 = 2g + 2w
60 - 2g = 2w Eq. 3
matching Eq. 1 and Eq. 3
g = 60 - 2g
g + 2g = 60
3g = 60
g = 60/3
g = 20 ft
From Eq. 1
g = 2w
20 = 2w
20/2 = w
w = 10 ft
Area
area = length * width
area = 20ft * 10 ft
area = 200ft²

the coordinates of the endpoints of ij are i(3,5) and j(17,19). point k is on ij and divides it such that ik:jk is 3:4. what are the coordinates of k?
Given that, the coordinates of the endpoints of ij are i(3,5) and j(17,19). point k is on ij and divides it such that ik:jk is 3:4.
The coordinates of the point k are (9,10)
The concept of section formula asserts that if a line segment is divided into two pieces in a certain ratio, the coordinates at the point of division may be obtained using the formula:
(mx2 + nx1)/(m+n), (my2 + ny1)/(m+n) = K
where (x1, y1) and (x2, y2) are the line segment's endpoint coordinates, and m:n is the provided ratio by which the line segment is divided.
The ends of the line segment IJ in this example are I(3,5) and J(17,19), and the ratio by which it is divided is 3:4, implying that IK:JK is 3:4.
As a result, m:n = 3:4, implying that m = 3 and n = 4.
When we enter these values into the formula, we get:
K = (3 x 17 + 4 x 3)/(3+4), (3 x 19 + 4 x 5)/(3+4)
When we simplify this expression, we get:
K = ( 51 + 12)/(7), (57 + 20)/(7)
K = (63)/(7),(77)/(7)
K = 9,10

What is a line segment ?
A line segment in geometry is bounded by two separate points on a line. Another way to describe a line segment is as a piece of the line that joins two points. A line segment has two fixed or distinct endpoints while a line has no endpoints and can stretch in both directions indefinitely.
We have segments ratio as shown:
BC/AB = CD/ED

A math test has 12 multiplication problems and 24 division problems.
What is the ratio value of multiplication problems to total problems?
Answer as a fraction in simplest form.
Answer: 1/3
Step-by-step explanation: The ratio of multiplication problems to total problems is 12:36, which can be simplified to 1:3.
Answer:
A
Step-by-step explanation:
Hi there.
We know this math exam has 12 multiplication and 24 division problems, making the overall exam questions 36 problems. (12+24=36)
The ratio is the fraction equivalent comparison between two variables. In this case, it's multiplication problems over total problems.
We know multiplication problems as 12, and we calculated the total, which is 36.
The answer would be 12/36; but it's divisible by 12 and can be further simplified to 1/3.
Relative to a fixed origin O, the point A has position vector (2i + 3j - 4k), the point B has position vector (4i - 2j + 3k), and the point C has position vector (ai + 5j – 2k), where a is a constant and a < 0.
D is the point such that AB = BD.
(a) Find the position vector of D.
Given AC| = 4,
(b) find the value of a.
Answer: (a) To find the position vector of point D, we need to find the midpoint of the line segment AB. We can do this by taking the average of the position vectors of points A and B:
D = (A + B) / 2 = ((2i + 3j - 4k) + (4i - 2j + 3k)) / 2 = (3i + 0.5j - 0.5k)
So, the position vector of point D is (3i + 0.5j - 0.5k).
(b) To find the value of a, we use the fact that the distance between points A and C is 4. We can find the distance between two points by finding the magnitude of the difference between their position vectors. The position vector of point C is (ai + 5j – 2k), so the difference between the position vectors of points A and C is (ai + 5j – 2k) - (2i + 3j - 4k) = (a-2)i + 2j - (-2k).
The magnitude of this difference is given by:
|(ai + 5j - 2k) - (2i + 3j - 4k)| = √((a-2)^2 + 2^2 + 2^2) = 4
So, we have:
√((a-2)^2 + 2^2 + 2^2) = 4
(a-2)^2 + 2^2 + 2^2 = 16
(a-2)^2 = 16 - 4 - 4
(a-2)^2 = 8
a-2 = ±2√2
Since a < 0, we have:
a = 2 - 2√2
So, the value of a is 2 - 2√2.

What is JL?
Right triangle J K L has K as its right angle. A segment connects K to M on side J L. Angle J M K is a right angle. K M equals 6 and J M equals 8.
JL =
Answer:
Step-by-step explanation:
To find the length of JL in the right triangle JKL, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides equals the square of the length of the hypotenuse (the longest side). In this case, JL is the hypotenuse and JK and KL are the two shorter sides.
Since K is a right angle in triangle JKL, we can find the lengths of JK and KL using the given information. We have KM = 6 and JM = 8, so we can use those values to find JK and KL:
JK = √(JM^2 - KM^2) = √(8^2 - 6^2) = √(64 - 36) = √(28) = 2√(7)
KL = KM = 6
Finally, to find JL, we can use the Pythagorean theorem:
JL = √(JK^2 + KL^2) = √( (2√(7))^2 + 6^2) = √(4 * 7 + 36) = √(52) = 2√(13)
So, JL = 2√(13).

The height above or below a specified reference point, most frequently a reference geoid, which is a mathematical representation of the Earth's sea level as an equipotential gravitational surface, determines a location's elevation. In most cases, elevation is used to describe locations on the surface of the Earth, whereas altitude or geopotential height is used to describe locations above the surface, such as those of flying airplanes or orbiting satellites, and depth is used to describe locations below the surface. Elevation should not be confused with the angular separation from the Earth's center. The summits of Mount Everest and Chimborazo have the highest elevation and greatest geocentric distance, respectively, because of the equatorial bulge.

The total area of the composite figure is 258 squared centimeters.
What is the area of the composite figure?The figure in the diagram is composed of two triangle and a rectangle?
The area of a triangle = 1/2 × base × height
Area of a rectangle = length × width
From the diagram;
Triangle 1
base = 4cmheight = 12cmTriangle 2
base = 12cmheight = 3cmRectangle
length = 18cmwidth = 12cmTo find the area of the composite figure, we find the area of the two triangle and rectangle and add.
Area = area of triangle 1 + area of triangle 2 + area of rectangle.
Area = ( 1/2 × base × height ) + ( 1/2 × base × height ) + ( length × width )
Area = ( 1/2 × 4 × 12 ) + ( 1/2 × 12 × 3 ) + ( 18 × 12 )
Area = ( 2 × 12 ) + ( 6 × 3 ) + ( 18 × 12 )
Area = 24 + 18 + 216
