a pyramid has an isosceles , triangle base with sides 25,25 and 48 units . the height of the pyramid is 30 units . calculate The volume of the pyramid
A pyramid has an isosceles triangle base with sides of 25,25 and 48 units.
The height of the pyramid is 30 units. The volume of the pyramid is 13What is the volume?We have a pyramid with four sides and a square base. Two-thirds of the pyramid's sides make up its height. The volume of a pyramid is 1, and we need to determine which of them matches our volume. Third, multiplying the length by the width gives us our base's area, which is s times s, or s square.This tells us that our base's height is equal to two-thirds of its side because it is a square base.
That makes it 2 to times s, or 2 s over 3. So we incorporate that into our equations next. We have a volume that is equal to 1/s squared / 2 / s spanning 3 points.Therefore, a pyramid has an isosceles triangle base with sides of 25,25, and 48 units.
The height of the pyramid is 30 units. The volume of the pyramid is 13To learn more about volume refer to:

5x - 2y = 3 and y = 2x
A. (3, 6)
B. (1, 4)
C. (1, 6)
D. (1, 9)
Answer:
the answer is A. (3,6)
Step-by-step explanation:
5x - 2y = 3
5x - 2(2x) = 3
5x - 4x = 3
x = 3
y = 2x
y = 2(3)

flagpole of height 5 meters is tied to the ground by a 7 meter cable. How far from the base of the flagpole is the cable tied
We know that
• The height is 5 meters.
,• The cable is 7 meters long.
Using the given information, we can represent the situation with a diagram.
In the diagram above you can observe that the x is a leg of the right triangle. So, we have to use Pythagorean's Theorem to find x.
[tex]7^2=5^2+x^2[/tex]Then, we solve for x.
[tex]\begin{gathered} 49=25+x^2 \\ x^2=49-25 \\ x^2=24 \\ x=\sqrt[]{24} \\ x\approx4.9 \end{gathered}[/tex]Hence, the base of the flagpole is 4.9 meters from the cable, approximately.write 34,000 , 43,000,000 , 0.0000087 , 91,000,000 , 16.6 x 10^3 , and 0.00372 x 10^-3 in scientific notation
To write a number in scientific notation you must know:
1. A number in scientific notation is written as the product of a number (integer or decimal) and a power of 10
2. A number can be converted to scientific notation by increasing the power of 10 by one for each place the decimal point is shifted to the left.
Then so:
[tex]34000=3,4x10^3[/tex][tex]43000000=4.3x10^7[/tex][tex]0.0000087=8.7x10^{-6}[/tex][tex]91000000=9.1x10^7[/tex][tex]16.6x10^3=1.66x10^4[/tex][tex]0.00372x10^{-3}=3.72x10^{-6}[/tex]PLEASE HELP!! THANK YOU

the tuition at a certain college was $29,694 last year and increased 5.6% from last year to the current year. how much is this year's tuition?
the tuition at a certain college was $29,694 last year
Intial Tution fees of college = $29,694
increased 5.6% from last year to the current year
i.e. Increased fees amonut = 5.6% of intial fees
So, tution of college at present year is : Intial Tution fees of college+ 5.6% of intial fees

pick a game of chance using cards or dice and a certain outcome in that game, (such as a large straight in yahtzee, or a four of a kind in poker). explain how many ways the outcome could happen and the total number of different hands or rolls there are in that game, and show the probability of your chosen outcome.
Yahtzee is a game of chance like dice or poker. The numbers of ways the outcomes ( straight rolling ) is 240 .
Probability of hitting a large straight is 240 / 7776 = 1/32
Yahtzee is the one of dice game that uses five standard six-sided dice. After rolling each die, the player can decide which die to keep and which to reroll. Goals include many different types of combinations, many of which originate from poker.
The two types of combinations that players must roll are called roads: small roads and large roads. Similar to poker straights, these combinations consist of consecutive dice. A small straight uses 4 out of the 5 dice and a large straight uses all 5 dice. Since the dice rolls are random, we can use probability to analyze the likelihood of hitting large straight on a single roll. Assumes that the dice used are fair and independent of each other. Now, you need to know how many ways you can roll a big/ large straight. Here it is more difficult than calculating the sample size. Big straights are harder to roll than small straights, but it’s easier to count the number of times you’ve rolled a big straight than the number of times you’ve rolled a small straight.
Next, determine the number of ways to get a straight by rolling the given dice. To get a nice straight with dice {1, 2, 3, 4, 5}, you can arrange the dice in any order. It turns out that you just swap the five dice. There are 5! = 120 ways to do this. There are two dice combinations that form the large Straight, each with 120 ways to roll, so there are 2 x 120 = 240 ways to roll the large Straight.
Now the probability of hitting a big/ large straight can be calculated with simple division. Since there are 240 ways to get the big straight in one roll, and 7776 rolls 5 dice, the odds of getting the big straight are 240/7776, close to 1/32, and lie 3.1%.

All the dimensions of the shape is found as 19 ft.
What is termed as the perimeter?The perimeter of any closed shape is the total length of its boundary. The total length around a shape is described as its perimeter. It is the length of any two-dimensional spatial shape's outline or boundary. Depending on the dimensions, the perimeters of irregular shapes can indeed be equal in size.For the given question, the dimensions of the shape is given as;
(4x-5) ft(25-x) ft(13 + x) ft(3x+1) ftThe perimeter of the shape = 76 ft.
The formula of the perimeter = sum of length of all sides.
Let 'P' be the perimeter.
P = (4x-5) + (25-x) + (13 + x) + (3x+1) ing
Simplifying
P = 4x - x + x + 3x - 5 + 25 + 13 + 1
76 = 7x + 34
7x = 76 - 34
7x = 42
x = 6
Thus, the dimensions of the shape is; Put x = 6
(4×6-5) ft = 19 ft(25-6) ft = 19 ft(13 + 6) ft = 19 ft(3×6+1) ft = 19 ftThus, all the dimensions of the shape is found as 19 ft.

give an example of a rational function that has a horizontal asymptote at y=3
An example of a rational function is y = (3x²+7x+4)/(x²+3x+2) which has a horizontal asymptote at y = 3.
To give it a horizontal asymptote of y = 3, we require the degrees in the numerator and denominator to be and the lead coefficient ratio to be 1.
Yet, in producing the hole, we need to have the rest of the function, disregarding the (x + 1)'s, = 1 when x = -1 to ensure the y-value of the hole is at + 1. When we add all of this together, we get.
y = (3(x+1)(x+k))/((x+1)(x+2)) and the last condition requires k = + 4/3, so
By distributing the 3 in the numerator to the 2nd linear component, we get.
y = (3(x+1)(x+4/3))/((x+1)(x+2))
y = ((x+1)(3x+4))/((x+1)(x+2))
y = (3x²+7x+4)/(x²+3x+2)
Thus, the example of a rational function is y = (3x²+7x+4)/(x²+3x+2) which has a horizontal asymptote at y = 3.

P(5 ≤ x ≤ 9) =
The probability P(5 ≤ x ≤ 9) is 0.6847
Assume that x has a normal distribution
We have been the mean and standard deviation μ = 6; σ = 2.
To calculate this probability we use the standardized normal distribution and the z-value for 5 and 9.
z = (5 - 6)/2
= -0.5
and z = (9 - 6)/2
= 1.5
Then the probability is calculated as:
P(x ≤ 5) = 0.3085
P(x ≤ 9) = 0.9932
P(5 ≤ x ≤ 9) = 0.9932 - 0.3085
P(5 ≤ x ≤ 9) = 0.6847
Therefore, the probability P(5 ≤ x ≤ 9) is 0.6847

Frank's gross capital gain was $2,100.
What is gross capital gain?
the discrepancy between the overall cost base of your asset and your capital gains. Your share of the capital gain - If more than one person owns this asset, your share of the gain is equal to the percentage of the asset that you personally hold.
You want the gross capital gain resulting from selling a stock purchased for $6,150 and sold for $8,250.
Capital Gain
The capital gain resulting from the sale is the difference between the selling price and the purchase price:
gain = selling price - purchase price
gain = $8,250 -6,150
gain = $2,100
