What is the volume of a square pyramid if the perimeter of the base is 44 in and the height is 19 in.? Round to the nearest tenth.
Answer:
2299 in^2
Step-by-step explanation:
The formula for the volume of a square pyramid of base A and height h is
V = (A)(h).
Here, the perimeter of the base is 44 inches, so that the length of one side must be (44 in) / 4, or 11 in. The area of a square of side s is A = s^2, so we have:
Here, V = (11 in)^2 * (19 in) = 2299 in^2
What is the 10th term in the geometric sequence? (2187, 729, 243, 81, 27)
The 10th term in the geometric sequence can be found by using the common ratio of 1/3 and applying it to the formula T(n) = a1 * r^(n-1). The 10th term is determined to be 1/9.
Calculating the 10th Term of a Geometric Sequence
To find the 10th term in the geometric sequence (2187, 729, 243, 81, 27), we first need to determine the common ratio (r). We can find r by dividing any term by its preceding term. Using the second and first terms, we get:
r = 729 / 2187 = 1/3
With the common ratio identified, we can use the formula for the nth term of a geometric sequence:
T(n) = a1 * r^(n-1)
Where a1 is the first term of the sequence and n is the term number. So, the 10th term (T(10)) is calculated as:
T(10) = 2187 * (1/3)^(10-1) = 2187 * (1/3)^9
To calculate this, we simply apply the exponent to the common ratio:
T(10) = 2187 * 1/19683 = 2187 / 19683 = 1/9
Therefore, the 10th term of the geometric sequence is 1/9.

The following histogram shows the theoretical probability of the number of heads you might get after flipping for coins simultaneously. If you were to flip four coins what is the probability that you get a two or more coins that land heads up?
Answer:
i think this is how you find it but i apologize if im wrong
Step-by-step explanation:
Use binomial probability since there are only two possibilities: success and failure, where success represents getting a heads, and tails being a fail. Therefore we are trying to find P(X=2), which is (42)⋅(0.5)2⋅(0.5)2=0.375.
The probability that you get two or more coins that land heads up is 0.6875.
What is the theoretical probability?Theoretical probability is an approach in probability theory that is used to calculate the probability of an outcome of a specific event.
The following histogram shows the theoretical probability of the number of heads you might get after flipping for coins simultaneously.
If you were to flip four coins what is the probability that you get two or more coins that land heads up is;
Probability = flip 0 coin + flip 1 coin + flip 2 coin
Probability = 0.375 + 0.25 + 0.0625
Probability = 0.6875
Hence, the probability that you get two or more coins that land heads up is 0.6875.

A hole the size of a photograph is cut from a red piece of paper to use in a picture frame. On a coordinate plane, 2 squares are shown. The photograph has points (negative 3, negative 2), (negative 2, 2), (2, 1), and (1, negative 3). The red paper has points (negative 4, 4), (4, 4), (4, negative 4), and (negative 4, negative 4). What is the area of the piece of red paper after the hole for the photograph has been cut? 17 square units 25 square units 39 square units 47 square units
Answer: D.
Step-by-step explanation:
First, find the area of the two squares:
The photograph: (-3, -2), (-2, 2), (2, 1), and (1, -3).
The square is diagonally aligned, so we need to find the length between two points in order to find the area.
I will use (1, -3) and (2, 1).
There is a 1 unit length and a 4 unit height. We can use the Pythagorean theorem to find the hypotenuse of the triangle, which is the length of the square's side:
1^2 + 4^2 = x^2
1 + 16 = x^2
x = square root of 17
The side length for the square of the photograph is the square root of 17, so the area of the photograph is 17 units^2.
The red paper has side lengths of 8. The distance between (-4, 4) and (4, 4) is 8 units wide, so we do not need to use the Pythagorean theorem.
Now that we know the area of the red paper and photograph, you can subtract the area to find the red paper with the hole:
64 - 17 = 47 square units.
Answer:
D
Step-by-step explanation:
Let's plot these points (see attachment).
We need to find the area of the paper and then the area of the photograph and subtract the photograph area from the red paper area.
The area of the big paper is easy; the side lengths of the square are 8 by 8, so the area is 8 * 8 = 64 square units.
Now, to find the area of the photograph, we just need the length of one side because it's a square. We use the distance formula between any two adjacent points; let's do (-2, 2) and (2, 1):
d = [tex]\sqrt{(2-1)^2+(-2-2)^2} =\sqrt{1+16} =\sqrt{17}[/tex]
Then the area is (√17)² = 17.
Subtract 17 from 64:
64 - 17 = 47
The area is 47 square units, or D.

What is the value of x in the equation 1.5(x + 4) - 3 = 4.5(x - 2)?
ОООО
A:3B:4C:5D:9
Answer:
x=4
Step-by-step explanation:
1.5(x + 4) - 3 = 4.5(x - 2)
Distribute
1.5x +6 -3 = 4.5x -9
Combine like terms
1.5x +3 = 4.5x -9
Subtract 1.5x from each side
1.5x -1.5x +3 = 4.5x -1.5x -9
3 = 3x-9
Add 9 to each side
3+9 = 3x-9+9
12 = 3x
Divide each side by 3
12/3 =3x/3

Answer:
B. 4
Step-by-step explanation:
Remember the acronym: PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction).
P: The expressions in the parentheses are not solvable as they are.
E: There are no exponents.
M: On the left, multiply 1.5 by x, giving you 1.5x, and by 4, giving you 6. We now have 1.5x + 6 -3 on the left. On the right, do the same. Multiply 4.5 by x, giving you 4.5x, and then multiply 4.5 by -2, giving you -9. Our expression is now 1.5x + 6 - 3 = 4.5x - 9.
D: There is no division in the problem.
A: There is no addition in the problem.
S: Subtract the 3 from the 6 on the left:. We now have 1.5x + 3 = 4.5x - 9.
Now that were all simplified, lets solve. Subract 1.5x from both sides so that only one side has x, so it can be solved. We now have 3 = 3x - 9.
Add 9 to both sides, to simplify even further. We now have 12 = 3x.
For the final step, we need to isolate x. To do this, we need to get rid of the coefficient. We know that 3 and x are being multiplied, so we can just divide to undo it. Keep in mind that we need keep both sides equal, so we divide both sides. By what? By 3. Now, we have our final answer:
x = 4

Suzanne needs material for her school project. She buys 3 1/4 yards of material at &2.50 a yard. What is the total cost of the material? Round to the nearest cent.
We have been given that Suzanne needs material for her school project. She buys 3 1/4 yards of material at &2.50 a yard. We are asked to find the total cost of the material.
To find the total cost of material, we will multiply the total yards of material by cost of material per yard as:
[tex]\text{Total cost of material}=\$2.50\times 3\frac{1}{4}[/tex]
[tex]\text{Total cost of material}=\$2.50\times \frac{13}{4}[/tex]
[tex]\text{Total cost of material}=\$0.625\times 13[/tex]
[tex]\text{Total cost of material}=\$8.125[/tex]
Upon rounding to nearest cent, we will get:
[tex]\text{Total cost of material}\approx \$8.13[/tex]
Therefore, the total cost of the material would be $8.13.

(a) The probability that the first person selected is a pledge is 10/33.(b) The probability that the first person selected is not a pledge is 23/33.(c) The probability that the second person selected is a pledge given that the first selected was also a pledge is 9/32 (since one pledge is already selected).(d) The probability that the second person selected is a full member given that the first person selected was a pledge is 23/32.(e) The probability that the second person selected is a pledge given that the first person selected was a full member is 10/32 or 5/16.(f) The probability that the second person selected is a full member given that the first person selected was also a full member is 22/32 or 11/16.(g) The probability that the second person selected is a pledge without any condition on the first selection needs additional information for a precise calculation.The group admission price at Wild World is given by the equation
p = 50 + 10n. Find the prices for groups with 5, 11, and 23 members.
To calculate the group admission prices for 5, 11, and 23 members at Wild World, we use the given equation p = 50 + 10n. The resulting prices are $100 for 5 members, $160 for 11 members, and $280 for 23 members.
Explanation:The group admission price at Wild World is determined by the equation p = 50 + 10n, where p is the total price and n is the number of members in the group. To find the prices for groups with 5, 11, and 23 members, we substitute the corresponding values of n into the equation.
For a group of 5 members: p = 50 + 10(5) = 50 + 50 = 100.For a group of 11 members: p = 50 + 10(11) = 50 + 110 = 160.For a group of 23 members: p = 50 + 10(23) = 50 + 230 = 280.The prices for groups with 5, 11, and 23 members are $100, $160, and $280 respectively.
