There is 50% increase in the change in the volume of cylinder A to A
The formula for the volume of the cylinder is given as
V = Πr^2h (1)
Where, r = radius of the cylinder
h = height of the cylinder
We have been given the radius and height of cylinder A which are,
r = 10 inches
h = 5 inches
Now putting the required values in equation (1) we get
V = Π(10)^2(5) cubic inches
V = Π*100*5 cubic inches
V = 500Π cubic inches
We have also been given the volume of cylinder B = 750Π
Thus percentage change in volume of cylinder = (750Π - 500Π)/500Π * 100
= 50%
Hence there is 50% increase in the change of the volume from cylinder A to B

What do you mean by GPS?Even though it appears complex, 3-dimensional trilateration is a straightforward mathematical process that underlies GPS. It's critical to have a fundamental understanding of 2-D Trilateration, which is necessary to completely comprehend 3-D Trilateration. Similar principles apply to three-dimensional trilateration, however, spheres rather than circles are used. Here is how the Global Positioning System uses 3-D trilateration to pinpoint an object's precise location. When the first satellite sends a signal, the GPS receiver measures the distance between the two. Say the distance between the receiver and the satellite is 20 000 miles. This implies that the receiver might be located anywhere on the 20 000 km diameter green sphere's surface and in any direction.

your bedroom sock drawer contains 4 green socks and 6 yellow socks that are mixed together. the light in your room is broken so you must select your socks in the dark. what is the probability you will select two socks of the same color on your first try?
The probability of selecting two socks of same color is 0.96.
According to the given question.
Total number of green socks = 4
Total number of yellow socks = 6
So, the total number of socks in a drawer = 4 + 6 = 10
Since as we know that, the probability of an event is computed as: P(E) = Number of favourable outcome /Total number of outcomes. Hence, the probability is the possibility of the occurrence of a random event.
So, the probability of selecting a green scoks = 4/10 = 2/5
And the probability of selecting a yellow socks = 6/10 = 3/5
Therefore, the probability of selecting two socks of same color
= probability of selecting both the green socks or probability of selecting both the yellow socks
= [( 2/5) + (2/5)] × [(3/5)+(3/5)]
= (4/5) × (6/5)
= 24/25
= 0.96
Hence, the probability of selecting two socks of same color is 0.96.

The measures of angles q, r and s are 100°, 135° and 125° and the sum of the three angles equals 360°.
What are the measures of missing angles of a geometric system?
In this problem we find a geometric system generated by three lines no collinear to each other, which generate the triangle DEF. In accordance with the Euclidean geometry, the sum of the measures of internal angles in a triangle equals 180°:
m ∠ FDE + m ∠ DEF + m ∠ DFE = 180° (1)
If m ∠ FDE = 80° and m ∠ DEF = 45°, then the measure of the angle DFE is:
m ∠ DFE = 55°
Finally, we find the values of the angles q, r and s by definition of supplementary angles:
q = 180° - 80°
q = 100°
r = 180° - 45°
r = 135°
s = 180° - 55°
s = 125°
The sum of the measures of angles q, r and s is:

29) A company planned to donate 640 bags of groceries, 320 cases of bottled water, and 800 small toys to a
local relief center. Suppose that the number of bags of groceries, cases of bottled water, and small toys are to be
placed in boxes with the same number of each good in each box. For instance, you could place 10 bags of
groceries and 5 cases of water in each of 64 boxes, but that would require 12.5 toys per box-oops! To be as
efficient as possible, assume that the company wants to use as few boxes as possible and must have a whole
number of groceries, water, and toys in each box.
a) How many boxes are needed? b) What are the contents of each box?
160 boxes needed to pack these items
Therefore contents in each box have 4 bags of groceries, 2 cases of bottled water, and 5 toys.
Given no of groceries bags = 640
number of cases of bottled water = 320
number of small toys = 800
We have to find out how many boxes are needed and the contents of each box.
(i) How many boxes are needed:
To do this we need to find the greatest common factor of these three items
as
640 - 2⁷ * 5
320 - 2⁶ * 5
800 - 2³ * 5²
GCF = 2⁵ * 5 = 160
Therefore 160 boxes needed to pack these items
(ii) Contents of each box:
No of bags of groceries in each box = 640 / 160 = 4
No of cases of bottled water = 320 / 160 = 2
No of toys in each box = 800 / 160 = 5
Therefore, contents in each box have 4 bags of groceries, 2 cases of bottled water, and 5 toys.

The perimeter is units. The area is
squareunits.
The perimeter of the polygon will be 20 units and the area will be 21 square units.
From the given vertices a rectangle will be formed. A rectangle is a closed figure in which each interior angle is a right angle. The Perimeter of the rectangle can be given by formula 2(l + b) and the area is given by l×b where l is the length and b is breadth of rectangle. Now from the given points the dimensions of rectangle will follow the order W (5, -1), X (5, 6), Z (2, 6) and Y (2, -1).
The length of the rectangle is given by l = √ (6 + 1) ² + (5 - 5) ²
l = √49
l = 7 units
The breadth of the rectangle is given by b = √ (6 - 6) ² + (2 - 5) ²
b = √9
b = 3 units
Now, the perimeter of rectangle = 2 (l + b)
P = 2(7 + 3)
P = 20 units
Area of the rectangle = l×b
A = 7×3
A = 21 square units.
Thus, the perimeter and area are 20 units and 21 square units respectively.

A particular antibiotic is eliminated from the blood with a half-life of 16 hours. how many hours does it take for 100-milligram dose to decrease to 30-milligrams in the blood?
Using the decay formula, the particular antibiotic with half-life of 16 hours, will decrease to 30-milligrams in the blood after 27.79 hours.
We can use the decay formula to solve the problem:
A(t) = A(0) . (0.5)^(t/T)
Where:
A(t) is the remaining quantity at time t
A(o) is the initial quantity
t is the time interval
T is the half-life rate
In the given problem:
A(0) = 100 milligram
T = 16 hours
A(t) = 30 milligram
We need to find t such that the remaining quantity of this antibiotic is 30 mg.
Substitute the given parameters into the formula:
A(t) = A(0) . (0.5)^(t/T)
30 = 100 . (0.5) ^(t/16)
Taking the logarithm:
log (30) = log [100 . (0.5) ^(t/16)]
Use the logarithm property, log(A.B) = log A + log B
log (30) = log (100) + log [(0.5) ^(t/16)]
Use the logarithm property, log(Aⁿ) = n.log A
log (30) = log (100) + (t/16) . log (0.5)
log (30) = 2 + (t/16) . log (0.5)
(t/16) . log (0.5) = log (30) - 2
t/16 = 1.737
t = 1.737 . (16) = 27.79 hours

In reality, the lateral face VAB is an isosceles triangle with a 14-length base and 25-length legs. This triangle's altitude must cut over angle V and the base, forming a right triangle with a hypotenuse that is 25 inches long and a short leg that is 7 inches long. We can calculate the altitude, which is also the slant height of the pyramid, using the Pythagorean theorem.
s.h. = alt. = √(252 - 72) = 24
Now, by adding the pyramid's height and half of its base, we may utilize this slant height as the hypotenuse of another right triangle.
We look at a regular octagon to identify half the base. You'll see that four of the sides are horizontal or vertical, while the other four are at an angle of 45 degrees to the first four. So, in this example, 14 + 28/2 = 14 + 142, the distance between parallel sides of a regular octagon would be equal to s + 2s/2.
hence, the base's half would equal 7 + 72.
The height of the pyramid and the dihedral angle with the base are both provided by this right triangle.
