Pyramids A and B are similar. Pyramid A has a height of 8 in., and Pyramid B has a height of 24 in. Pyramid A has a volume of 384 in3. What is the volume of pyramid B?
Answer:142
Step-by-step explanation:no
The volume of Pyramid B can be calculated by using the ratio of the heights of the similar pyramids, cubed. As the height of Pyramid B is 3 times the height of Pyramid A, its volume is 27 times greater. Thus, Pyramid B has a volume of 10368 cubic inches.
Explanation:
Calculating the Volume of Similar Pyramids
To solve this problem, we can use the properties of similar figures. When two pyramids are similar, the ratio of their volumes is equal to the cube of the ratio of their corresponding linear dimensions. In this case, Pyramid A has a height of 8 inches and a volume of 384 cubic inches. Pyramid B is similar to Pyramid A but has a height of 24 inches, which is 3 times the height of Pyramid A (since 24 in. / 8 in. = 3).
Since the pyramids are similar, the ratio of their volumes will be the cube of the ratio of their heights (in this case, 33 or 27). Therefore, the volume of Pyramid B will be 27 times greater than the volume of Pyramid A.
To find the volume of Pyramid B, we simply multiply the volume of Pyramid A by this ratio:
Volume of Pyramid B = Volume of Pyramid A × (ratio of heights)3Volume of Pyramid B = 384 [tex]in^3[/tex] × 27Volume of Pyramid B = 10368 [tex]in^3[/tex]Thus, the volume of Pyramid B is 10368 cubic inches.
In a certain Algebra 2 class of 26 students, 16 of them play basketball and 9 of them play baseball. There are 5 students who play both sports. What is the probability that a student chosen randomly from the class plays basketball or baseball?
Answer:
10/13 ≈ 76.9%
Step-by-step explanation:
P(A∪B) = P(A) +P(B) -P(A∩B)
P(plays basketball ∪ plays baseball)
= P(plays basketball) +P(plays baseball) -P(plays both)
P(plays basketball ∪ plays baseball) = 16/26 +9/26 -5/26 = 20/26 = 10/13
P(plays basketball or baseball) = 10/13 ≈ 76.9%

It takes Jill 2 hours to run 14.5 miles, At this rate, how far could she run in 3 hours? Btw, I am giving a lot of points if you get it correct!
Answer:
21.75
Step-by-step explanation:
To find how long she can run in a single mile, divide 14.5 by 2, giving you 7.25. If she runs three of those, (3 times 7.25), she runs 21.75 miles.
Answer: 21.75miles
Step-by-step explanation:
Let the number of miles for 3 hours be represented as x
If 2 hours = 14.5 miles
Then, 3 hours = x
We Cross multiply
2x = 14.5 × 3
2x = 43.5
Divide both sides by 2
x = 43.5/2
x = 21.75
In 3 hours, Jill will be able to run 21.75miles. I hope this helps.
Jen's garden is 4 feet wide and gas ab area of 28 square feet. What is the length of Jne's garden? how do you know
Answer:
The Length is 7
Step-by-step explanation:
If Jen has a garden with a total area of 28 square feet and it is 4 feet wide to find the length you will divide the total area with the width. This should give you the length of the Garden which is 7. To double check your answer you can multiply the width with the length to get the total area of 28 square feet.
The length of Jen's garden is 7 feet, calculated by dividing the area of 28 square feet by the width of 4 feet.
Explanation:To find the length of Jen's garden, we need to use the information about the garden's area and width. The area of a rectangle (which is the shape we can assume the garden is) is calculated by multiplying the length by the width. Given that Jen's garden has an area of 28 square feet and a width of 4 feet, we can set up the following equation:
Area = Length × Width
28 square feet = Length × 4 feet
To solve for the length, divide both sides of the equation by 4 feet:
Length = 28 square feet / 4 feet
Length = 7 feet
Therefore, the length of Jen's garden is 7 feet. This is how we determine the dimensions of a garden plot by using multiples of length and width. To actually measure the garden, one would use a measuring tape.
Solve of x:
0.5(4x + 6) = 5x + 24.7
Answer:
[tex]0.5(4x + 6) = 5x + 24.7 \\ 2x + 3 = 5x + 24.7 \\ 3 - 24.7 = 5x - 2x \\ - 21.7 = 3x \\ \frac{ - 21.7}{3} = \frac{3x}{3 } \\ x = - 7.2333[/tex]
Answer:
x=-37.4
Step-by-step explanation:
0.5(4x + 6) = 5x + 24.7 (0.5*4x=4.5x)
4.5x+6=5x+24.7
4.5x-5x+6=5x-5x+24.7
-0.5x+6=24.7
-0.5x+6-6=24.7-6
-0.5x=18.7
-0.5x/-0.5=18.7/-0.5
x=-37.4
If Abby rolls two number cubes a hundred times, about how many times would she expect a product greater than 10.
Answer:
20 times ??
Step-by-step explanation:
Abby would expect to roll a product greater than 10 about 42 times in 100 rolls of two number cubes.
To determine how many times Abby would expect to roll a product greater than 10 when rolling two number cubes (dice) a hundred times, we can use probability.
Each number cube has six sides, numbered 1 through 6. When two dice are rolled, the possible products range from 1 (1*1) to 36 (6*6).
To find the probability of getting a product greater than 10, we can list out the combinations that result in products greater than 10:
(2, 6), (3, 5), (3, 6), (4, 4), (4, 5), (4, 6), (5, 3), (5, 4), (5, 5), (5, 6), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)
That's a total of 15 combinations out of 36 possible combinations.
So, the probability of rolling a product greater than 10 is [tex]\( \frac{15}{36} \).[/tex]
To find out how many times Abby would expect this to happen in 100 rolls, we multiply the probability by the number of trials:
[tex]\[ \text{Expected occurrences} = \text{Probability} \times \text{Number of trials} \][/tex]
[tex]\[ \text{Expected occurrences} = \frac{15}{36} \times 100 \][/tex]
[tex]\[ \text{Expected occurrences} \approx \frac{5}{12} \times 100 \][/tex]
[tex]\[ \text{Expected occurrences} \approx 41.67 \][/tex]
So, Abby would expect to roll a product greater than 10 approximately 42 times in 100 rolls.
What is the distance between (–2 and one-half, –3) and (1, –3)?
The answer is square root of 2
Answer: The distance between the points is 2 and 1/2 units.
Step-by-step explanation:
We want to calculate the distance between the points:
First, to calculate the difference between the vectors (a,b) and (c,d) we have:
(a, b) - (c, d) = (a -c, b - d)
(-2 + 1/2, -3) and (1, - 3)
First, we calculate the difference of the two ponts:
(-2 + 1/2, -3) - (1, - 3) = (-2 + 1/2 - 1. -3 - (-3)) = (-3 + 1/2, 0 )
now this is the distance vector, we can calculate the magnitude of the distance by calculating the magnitude of this vector, this is:
d = √((-3 +1/2)^2 + 0^2) = √(-3 + 1/2)^2 = (3 - 1/2) = 2 + 1/2

Can I get help please ?
Answer:
8
Step-by-step explanation:
1) let’s take the original number as “x”
So
3x=28-0.5x
Lol don’t worry I’ll show you how I got that
So it says 3 times a number. That tells me my number, X is multiplied by 3 so I have
3x so far
Next it says “is equal to”, this tells me my number 3x is equal to something so I have this now:
3x=
After that it says “half of a number” so I know I will have 0.5x subtracted from 28. Since it says subtracted from 28 that means my number will be subtracted from 28, not the other way around so
3x=28-0.5X
Now I can solve this by bringing “-0.5” to the left.
3x+0.5x=28
3.5x=28
Divide both sides by 3.5 and
X=8
Mike, Chris, and John decided to go running. Mike can run 4 miles per hour, Chris
can run 6 miles per hour, and John can run 5 miles per hour. Mike ran for 1 hour
and 45 minutes, Chris ran 70 minutes, and John ran for 90 minutes. What was
the total amount of miles that they combined to run?
1. 25.5 miles
2. 25 miles
3. 21 miles
4. 21.5 miles
5. 22.5 miles
Answer:
21.5 miles total
Step-by-step explanation:
First, identify what you know:
1) Mike can run 4 mph, and runs a total of 1 hour, and 45 minutes (105 min)
2) Chris can run 6 mph, and runs a total of 70 minutes.
3) John can run 5 mph, and runs a total of 1 hour, and 30 minutes (90 min)
We need to calculate how many miles each person ran, and then add the miles ran, to find the total!
Mike: 1 hour and 45 minutes it equal to 1.75! So, in one hour, Mike ran 4 miles. He ran 3/4 of 4 mph, in 3/4 of an hour! Thus, Mike ran 7 miles. Simply multiply 1.75 by 4, to get 7 mph.
Chris: Chris ran 6 mph for 70 minutes. 6 mph, means that Chris can run one mile per every ten minutes! In 70 minutes, he'll have run 7 miles.
John: If john ran 90 minutes, that means he ran 1.5 hours! Simply multiply 1.5 by 5 mph, to get 7.5 miles!
Now, all we need to do, is add the totals!
7 + 7 + 7.5 = 21.5
In total, Mike, Chris, and John ran 21.5 miles!

Kendra lives 10 Km from the northern tip of swan lake and 6 Km from the southern tip of swan lake. What is the north - south distance across swan lake?
Answer:
The north - south distance across swan lake is 8 km
Step-by-step explanation:
Look to the attached figure
Kendra's house and the distances between it and the North tip, southern tip of swan lake formed a right Δ
∵ Kendra lives 10 Km from the northern tip of swan lake
- That means the length of the hypotenuse of the right Δ is 10
∴ The hypotenuse of the right Δ = 10
∵ Kendra lives 6 Km from the southern tip of swan lake
- That means the length of the horizontal leg of the right Δ is 6
∴ The horizontal leg = 6
- By using Pythagoras Theorem
∵ (hypotenuse)² = (H.leg)² + (V.leg)²
∴ (10)² = (6)² + (x)²
∴ 100 = 36 + x²
- Subtract 36 from both sides
∴ 64 = x²
- Take √ for both sides
∴ 8 = x
∴ The vertical leg of the right triangle = 8
∵ x represents the north-south distance across swan lake
∴ The north - south distance across swan lake is 8 km

Sue bought 3.5 yards of material at $8.70 per
yard and 5 yards of lace trim. She spent $32.90 in
total. Calculate the cost of 1 yard of lace trim.
Answer: $.49
step explanation:
Sue bought 3.5 yards of material at $8.70 per yard (3.5x8.70=30.45)
Sue also bought 5 yards of lace trim.
Her total was 32.90 and we want to find out how much the lace trim cost.
We will subtract the initial material to get the subtotal cost for just the lace trim. (32.90-30.45=2.45)
5 yards of lace trim total up to $2.45. To get how much each yard cost we will divide (2.45÷5=.49)
Each yard of lace trim costs $.49 cents
