Answer:
The dimensions are 3, 4 and 5 inches.
Step-by-step explanation:
Area = 1/2 * height * base
6 = 1/2 * h * b
h * b = 12.
As the hypotenuse is 5 inches long
H^2 + B^2 = 5^2
From the third line: h = 12/b, so we have
(12/b)^2 + b^2 = 25
144/b^2 + b^2 = 25
144 + b^4 = 25b^2
b^4 - 25b^2 + 144 = 0
Let B = b^2, so
B^2 - 25B + 144 = 0
(B - 16)(B - 9) = 0
B = 16, 9
So, b = 4, 3
h = 12/b
= 3 , 4.

two valleys are sometimes infected with tree rot. suppose valley 1 is infected with probability 35%, valley 2 is infected with probability 60%, and the probability that at least one is infected is 80%. suppose tree rot is observed in valley 2. what is the probability that valley 1 is also infected?
The probability that valley 1 is also infected is 15%
The math term probability is defined as the possibility of an event to happen is equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Here we have know that two valleys are sometimes infected with tree rot.
The probability of rotting valley 1 = 35%
The probability of rotting valley 2 = 60%
And the probability that at least one is infected = 80%
When we convert these values into decimal then we get,
The probability of rotting valley 1 = 0.35
The probability of rotting valley 2 = 0.6
And the probability that at least one is infected = 0.8
Then the probability that valley 1 is also infected is
=> P = 0.35 + 0.6 - 0.8
=> P = 0.15
When we convert it into percentage then we get,

tickets number one 1 to 20 are mixed up and then a ticket is drawn at random what's the probability that the ticket drawn at random has a multiple of four or five
The probability that the ticket drawn at random has a multiple of four or five is 2/5.
We have to determine the probability that the ticket drawn at random has a multiple of four or five.
Tickets number 1 to 20 are mixed up and then a ticket is drawn at random.
Total number of tickets = 20
The possible numbers of tickets that are multiple of four or five = 4, 5, 8, 10, 12, 15, 16, 20
So total number of outcome that are multiple of four or five = 8
So, the probability that the ticket drawn at random has a multiple of four or five = Total number of outcome that are multiple of four or five/Total number of tickets
The probability that the ticket drawn at random has a multiple of four or five = 8/20
The probability that the ticket drawn at random has a multiple of four or five = 2/5

Roger received $200 for his birthday. He wants to use the money to buy new clothes for work. He can buy pants
for $30 and shirts for $20. He wants at least 6 new items. Determine the shirt and pants combination Roger
can buy.
Answer: He can buy 4 pants for $120 and 4 shirts for $80
Answer: Roger wants to buy at least 6 items, so he needs to buy at least 6 pants or 6 shirts or a combination of both.
Step-by-step explanation:
The cost of 6 pants is $30 x 6 = $180.
The cost of 6 shirts is $20 x 6 = $120.
If Roger wants to buy both pants and shirts, he can buy 3 pants and 6 shirts for a total cost of $90 + $120 = $210.
Another option would be 4 pants and 5 shirts for a total cost of $120 + $100 = $220.
Thus, Roger can buy either 6 pants, 6 shirts or a combination of 3 pants and 6 shirts or 4 pants and 5 shirts with his $200.
Find the lateral surface area of the cylinder round your answer to the nearest hundredth

Now, According to the question:
In two-dimensional geometry, a cylinder has two circles as its bases so that both the bases are parallel and congruent.
In a cylinder, there is a lateral surface that is between the bases.
Let us suppose d is the diameter of the base of a cylinder, and h is the height of the cylinder then:
Radius of the cylinder (r) = [tex]\frac{d}{2}[/tex]
Lateral surface area of the cylinder(S) = [tex]2\pi rh[/tex]
Total surface area(A) = lateral area + total area of the bases
Given that the diameter of the above cylinder is 12cm, and the height of the cylinder is 3.5cm.
d = 12cm
and,
h = 3.5cm
Now the radius of the cylinder:
(r) = [tex]\frac{d}{2}[/tex] = 12/2 = 6cm
Now the total surface area of the cylinder:
A = [tex]2\pi r(h +r)[/tex]
A = [tex]2\pi (6)(3.5+6)[/tex]
A = [tex]12\pi (9.5)[/tex]

PLEASE ANSWER THE QUESTION ITS URGENT!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Varun takes 4 rotis per meal and Rosa takes 2 per meal
Varun wastes 40 rotis in 20 days
How to determine the number of Rotis per meal and the Rotis wastedLet's call the number of rotis Varun takes per meal "V".
We know that Rosa takes half the amount of rotis as Varun, so Rosa takes V/2 rotis per meal.
Together, they take V + V/2 = 1.5V rotis per meal.
If they consume 120 rotis in 20 days, that means the amount they consume is
Amount = 120/20 = 6 rotis per day.
So, 1.5V = 6, and V = 4.
Varun takes 4 rotis per meal and wastes 4/2 = 2 rotis per meal.
Over 20 days, Varun would waste 2 * 20 = 40 rotis.

Determine the perimeter of the right triangle shown. Round your answer to the nearest whole number, if necessary.
O 7 Units
O 14 Units
O 25 Units
O 26 Units
Answer: 26 units
Step-by-step explanation:
Let's label the left side as side a, the bottom as side b, and the hypotenuse (the diagonal side) as side c.
As you can see, side a is 8 units, and side b is 7 units. To calculate side c, you need to plug both a and b in to the Pythagoras' theorem, which states that a² + b² = c².
> 8² + 7² = c²
> 64 + 49 = c²
> 113 = c²
> c = 10.63 which would round up to 11.
Now adding up all the sides together, a + b + c = 7 + 8 + 11 = 26 units

We know 6 preceedes 7 and the number is rounded to nearest tenth. So, the just possible number will be 45.69. However, as mentioned, it will be rounded to 45.7. The same will happen for till 45.65. Proceeding before this, we get 45.64 which will not be rounded to 45.7. Thus, the smallest possible number is 45.65 centimetres.

How many teachers must attend for this to be a good decision?
This means that if 7 or more teachers attend the training, it will be a good decision, as the cost of sending them will be less than the cost of not sending them.
What is an algebraic manipulation?
Algebraic manipulation is the process of rearranging mathematical expressions in order to solve equations or to make them easier to understand. It involves the use of mathematical operations and properties such as addition, subtraction, multiplication, division, and the commutative, associative, and distributive properties.
To determine if sending teachers to the summer training on mentor groups is a good decision, the committee needs to calculate the break-even point. This is the point at which the cost of sending the teachers is equal to the cost of not sending them. The break-even point can be calculated by dividing the advanced payment by the difference between the cost at registration and the advanced payment.
In this case, the break-even point is: $1,250 ÷ ($175 - $1,250) = $1,250 ÷ -$1,075 = 7 teachers.

By polar form properties, the product of complex numbers (5 · cos 225° + i 5 · sin 225°) and (2 · cos 135° + i r₂ · sin 135°).
How to multiply complex numbers
In this question we find the case of the product of two complex numbers in rectangular form but including features of polar form (magnitude, direction). Then, we have the following situation:
(r₁ · cos θ₁ + i r₁ · sin θ₁) · (r₂ · cos θ₂ + i r₂ · sin θ₂)
Result can be found easily by transforming the expression into polar form:
(r₁, θ₁) · (r₂, θ₂) = (r₁ · r₂, θ₁ + θ₂)
[r₁ · r₂ · cos (θ₁ + θ₂) + i r₁ · r₂ · sin (θ₁ + θ₂)]
If we know that r₁ = 5, r₂ = 2, θ₁ = 225° and θ₂ = 135°, then the product of the complex number is:
10 · [cos 360° + i sin 360°]
10 · (1 + i 0)

A set of data contains 10 negative numbers and 4 positive numbers. Which one of these statements must be true?
Statement "B. the median is a negative number" will be correct among these options.
What is Mean?The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.
Given, that A set of data contains 10 negative numbers and 4 positive numbers.
Since the value of data is not given it can be any positive or negative numbers
mode:
A mode is described as a value in a group of values that occurs most frequently. The value that appears the most frequently is this one.
Range:
When the sample maximum and minimum are subtracted, the range of a set of data in statistics is the difference between the greatest and lowest values.
Median:
The median is the value that's exactly in the middle of a dataset when it is ordered.
Thus, the Median will be negative.
Therefore, Statement "B. the median is a negative number" will be correct among these options.
