The area of a triangle is 1440cm^2 the base of tge triangle is 5 times the height of the triangle
Answers
Probably base and the height...
Area = 1440cm²
base = 5×height
base = 5h
Area of triangle = base × height
1440 = 1/2 × 5h × h
1440 = 5h²/2
5h² = 2880
h² = 2880/5
h² = 576
h=24cm..
Height = 24cm
Since base = 5h
Base = 5×24
Base = 120cm...

what does 4x+5x-30=180 equal
Answers
Combining like terms gives
9x−30=180. Adding 30 to both sides yields
9x=210. Dividing by 9, we find x=23.3333.
To solve the equation
4x+5x−30=180, we first combine like terms:
4x+5x=9x
So the equation becomes:
9x−30=180
Next, we isolate the variable
x by adding 30 to both sides:
9x=180+30
9x=210
Finally, we divide both sides by 9 to solve for

Answer:
The land area of Australia in square meters is:
7.61848E + 12 m ^ 2
Final answer:
The land area of Australia is roughly 7.62 trillion square meters, calculated by multiplying the area in square miles (2,941,526) by the conversion factor of 2,590,000 square meters per square mile.
Explanation:
The student is asking for the conversion of Australia's land area from square miles to square meters. To convert square miles to square meters, we use the conversion factor that 1 square mile is equal to 2.59 square kilometers or 2,590,000 square meters. Therefore, the land area of Australia in square meters is calculated by multiplying the area in square miles by the conversion factor:
2,941,526 mi2 × 2,590,000 m2/mi2 = 7,619,652,340,000 m2

Answers
The triange may be classified as (2) isosceles triangle
How to classify the triangle?The vertices are given as:
A(0,0), B(3,2), and C(0,4)
Calculate the side lengths using:
d = √(x2 - x1)^2 +(y2 - y1)^2
So, we have:
AB = √(3 - 0)^2 +(2 - 0)^2
AB = √13
AC = √(0 - 0)^2 +(4 - 0)^2
AC = 4
BC = √(3 - 0)^2 +(2 - 4)^2
BC = √13
Side lengths BC and AB are equal
i.e. AB = BC = √13
Hence, the triange may be classified as (2) isosceles triangle

I have drawn and attached the graph with the answer.
Step-by-step explanation:
The graph given can be further simplified as follows:
[tex]g(x)=2x-1+3[/tex]
[tex]g(x)=2x+2[/tex]
Slope of the graph is 2 as x has a coefficient of 2 and intercept is 2.
To graph the above substitute several values to x and calculate the corresponding g(x) values.
[tex]g(1)=2*1+2\\g(1)=4[/tex]
So when x=1, g=4

What is the correct solution for the arithmetic expression (2+8)/2*9/3 using the order of operations employed by oracle 12c when solving equations??
Answers
The order of operations is the steps used to simplify any mathematical expression. Order of operations refers to which operations should be performed in what order and it is denoted by PEMDAS, This means that you should do what is possible within parentheses first, then exponents, then multiplication and division (from left to right), and then addition and subtraction (from left to right). If parentheses are enclosed within other parentheses, work from the inside out.

If the arrival of major road vehicles can be described by the poisson distribution, and the peak hour volume is 1000 veh/hr. the value of the critical gap is 4 seconds. the expected number of available gaps during the peak hour is equal to:
Answers
expected no. of vehicles per 4 minute interval = 1000/(3600/4) = 10/9 = λ
Using the poisson distribution, probability that no vehicles within the 4 second interval
P(0)= λ ^0 e^(- λ )/ 0!
= (10/9)^0 e^(-10/9) / 1
= e^(-10/9)
= 0.3292 (approx.)
In an hour, there are n=3600/4=900 such intervals, each with probability of p=0.3292 occurring.
Applying binomial distribution,
expected number of gaps
=np
=900*0.3292
= 296.3
Answer: the expected number of gaps is 296 (to the nearest unit).
Note: in fact, the actual expected number will be higher because gaps do not line up at 4 second intervals. If a vehicle passes at the 1 second of the interval, a gap can commence at the next second. Therefore the expected value could/should be slightly higher.
The height of the pyramid in the diagram is three times the radius of the cone. The base area of the pyramid is the same as the base area of the cone. What is the expression for the volume of the pyramid in terms of the radius r of the cone?
Answers
Let radius of cone = r
Then, height of the pyramid = 3r
Area of the base of the cone = pi x r^2 = area of the pyramid.
If the base dimensions of the pyramid are l and b, then area of the pyramid, l x b = pi x r^2.
The volume of the pyramid = 1/3 x l x b x h
We know, l x b = pi x r^2 and h = 3r.
Thus, volume of pyramid is = 1/3 x pi x r^2 x 3 r = pi x r^3
The volume of the pyramid is πr³ cubic units. Then the correct option is A.
What is the volume of the pyramid?Suppose the base of the pyramid has length = L units, width = W units, slant height = K units, and the height of the pyramid is of H units.
Then the volume of the pyramid will be
V = (A × H) / 3
V = (L × B × H) / 3
Where, A is the base area of the pyramid.
Let r be the radius of base circle of the cone.
The height of the pyramid in the diagram is three times the radius of the cone.
Then the height of the pyramid will be 3r.
The base area of the pyramid is the same as the base area of the cone.
Base area of pyramid = Base area of cone
Base area of pyramid = πr²
Then the volume of the pyramid will be
Volume of pyramid = (1/3) x πr² x (3r)
Volume of pyramid = πr² x r
Volume of pyramid = πr³ cubic units
The volume of the pyramid is πr³ cubic units.
Then the correct option is A.

f=11gh solve the formula for the variable h.
Answers
The formula f=11gh can be solved for h by dividing both sides of the equation by 11g. This will give h = f / (11g), where h is isolated on one side of the equation.
Explanation:To solve the formula f=11gh for the variable h, we need to isolate h on one side of the formula. The current formula tells us that the value of f is equal to the result of 11 times g times h.
As our goal is to solve for h, we can do this by dividing both sides of the equation by 11g. In doing so, the 11g on the right side of the equation will cancel out, leaving us with just h on one side.
So the formula solved for h will look like this:
h = f / (11g).

From a top-down 2D perspective, a car moves in a diagonal line and travels a distance equivalent to 80 miles. If the angle between the diagonal line and a horizontal reference line is 25 degrees, how far did the car travel horizontally and vertically? If necessary, round your answers to the nearest tenth of a mile. Horizontal distance? Vertical distance?
Answers
The diagonal line would be hypothenuze. Horizontal and vertical distance would be other two sides of a triangle.
We will use the following formulas:
[tex]sin \alpha = \frac{opposite}{hypothenuze} \\ cos \alpha = \frac{adjacent}{hypothenuze} [/tex]
Where opposite side is vertical distance and adjacent side is horizontal distance.
Solving for these two sides we have:
[tex]opposite = hypothenuze * sin \alpha \\ adjacent = hypothenuze * cos \alpha [/tex]
We insert numbers and we get solution:
[tex]opposite = 80 * sin 25 = 33.8miles \\ adjacent = 80 * cos 25 = 72.5miles [/tex]

Consider a normal population distribution with the value of σ known. (a) what is the confidence level for the interval x ± 2.88σ/ n ? (round your answer to one decimal place.) % (b) what is the confidence level for the interval x
Answers
The confidence level for the interval x ± 2.88σ/√n is approximately 99.9%. The term 'confidence level' speaks to how frequently the true value of the parameter would be inside the interval for replicated experiments. Without additional information, we cannot compute the confidence level for just 'x'.
Explanation:In statistics, a formula exists to find the confidence interval. For the interval x ± 2.88σ / √n, the confidence level is nearly 99.9%. We find this by referring to the z-table (standard normal table) with a z-score of 2.88. This leaves 0.05% in each tail of the distribution.
On the topic of confidence levels, a 95% confidence interval implies that if you were to take 100 random samples from your population, approximately 95 of those samples would capture the true population parameter.
For the other part of your question, when we talk about the interval x, it doesn't provide enough detail to calculate a confidence level. It needs to be stated in context of the standard deviation and the sample size.
