Are rhombuses also rectangle?? Explain
Answer:
No, rhombuses are not necessarily rectangles. While both shapes are quadrilaterals with opposite sides parallel, there is an additional requirement for a rectangle that is not present in a rhombus. Specifically, a rectangle must have all interior angles measuring 90 degrees, while a rhombus can have any angle between 0 and 180 degrees.
On the other hand, all rectangles are parallelograms, while not all parallelograms are rectangles. Similarly, all squares are both rhombuses and rectangles, but not all rhombuses or rectangles are squares. In summary, a rhombus is a quadrilateral with four equal sides, while a rectangle is a quadrilateral with four right angles. While there is some overlap between the definitions, they are not equivalent.
Answer:
Rhombuses are not rectangles
Step-by-step explanation:
This is because rhombuses do not have 4 right angles.
A square would be a rectangle because its a quadrilateral with 4 right angles
while a rectangle wouldn't be a square because it doesn't have 4 equal sides
A rhombus is a quadrilateral that has 4 equal sides but doesn't have 4 right angles, making it not a rectangle

The back of a garbage truck is 23 feet long, 8 feet wide, and 12 feet tall. How many loads of trash from the garbage truck will it take to fill a 40 foot by 9 foot by 8 foot storage container?
it will take approximately 1.30 loads of trash from the garbage truck to fill the 40-foot by 9-foot by an 8-foot storage container. However, since you can't have a partial load, you would need to round up to 2 loads to completely fill the container.
what is an algebraic expression?
An algebraic expression is a combination of numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, and division) that can be simplified and evaluated.
To determine the number of loads of trash from the garbage truck that will fill a 40-foot by 9-foot by 8-foot storage container, we need to compare the volume of the container to the volume of the garbage truck's back.
The volume of the garbage truck's back is:
V_garbage_truck = length x width x height
V_garbage_truck = 23 ft x 8 ft x 12 ft
V_garbage_truck = 2,208 cubic feet
The volume of the storage container is:
V_container = length x width x height
V_container = 40 ft x 9 ft x 8 ft
V_container = 2,880 cubic feet
To find out how many loads of trash from the garbage truck will fill the storage container, we need to divide the volume of the container by the volume of the garbage truck's back:
Number of loads = V_container / V_garbage_truck
Number of loads = 2,880 cubic feet / 2,208 cubic feet
Number of loads ≈ 1.30 loads
Therefore, it will take approximately 1.30 loads of trash from the garbage truck to fill the 40-foot by 9-foot by an 8-foot storage container. However, since you can't have a partial load, you would need to round up to 2 loads to completely fill the container.

What is density? How is density calculated?The amount of mass that a material has in relation to its volume is measured by its density. By dividing the substance's mass by volume, it is determined. Density is calculated as follows: density = mass/volume
A fundamental idea in physics, density is utilised in many branches of research and engineering, including the construction of effective engines and turbines, calculating the buoyancy of objects in fluids, and forecasting the behaviour of materials under stress.
Given that, average density of the entire pyramid is 4.7g/cm3 and that the bottom part has a mass of 972.8g.
The density is given as:
density = mass/volume
Substituting the value we have:
4.7g/cm3 = 972.8g/volume
volume = 207.23 cubic cm.
For the top part, density of 2.9g/cm3 and a mass of 92.8g. :
density = mass/volume
2.9g/cm3 = 92.8g/volume
volume = 32 cubic cm.
The percent of the top part with respect to total volume is:
percentage = (volume of top part / total volume) x 100
total volume = volume of top part + volume of bottom part
total volume = 32 cm3 + 207.23 cm3
total volume = 239.23 cm3
percentage = (32 cm3 / 239.23 cm3) x 100
percentage = 13.4%

Huntington’s disease is a genetic disorder that doesn’t appear until the middle adult years. Because of this, many victims of the disease have children before they know they are sick. Their children have a one-in-two chance of developing the disease.
Of the next 10 children born to couples where one of the parents has the disease, what is the probability that exactly 5 of them will get Huntington’s disease?
What is the probability that exactly 7 of the ten will get Huntington’s disease?
The probability of exactly 5 out of the next 10 children getting Huntington's disease is 0.2461, and the probability of exactly 7 getting the disease is 0.1172.
What is the probability?
Probability is the study of the chances of occurrence of a result, which are obtained by the ratio between favorable cases and possible cases.
This problem can be solved using the probability , where we have a fixed number of trials (10 children) and a fixed probability of success (one-in-two chance of getting the disease).
The probability of getting exactly k successes in n trials, each with probability p of success, is given by the binomial probability formula:
P(k) = (n choose k) * [tex]p^k * (1-p)^{(n-k)[/tex]
where (n choose k) is the binomial coefficient, which represents the number of ways to choose k items out of a set of n.
For this problem, we have n = 10, p = 1/2 (since the children have a one-in-two chance of getting the disease), and we want to find P(5) and P(7).
P(5) = (10 choose 5) * ([tex]1/2)^5 * (1/2)^{(10-5)} = 0.2461[/tex] (rounded to four decimal places)
P(7) = (10 choose 7) * [tex](1/2)^7 * (1/2)^{(10-7)} = 0.1172[/tex] (rounded to four decimal places)
Hence, The probability of exactly 5 out of the next 10 children getting Huntington's disease is 0.2461, and the probability of exactly 7 getting the disease is 0.1172.

how to find the inverse for question B. Y = 4x^2-2
Answer:
x = ± √((y + 2)/4)
Step-by-step explanation:
To find the inverse of a function, we need to solve for x in terms of y.
Steps to find the inverse of y = 4x^2 - 2:
Replace y with x and x with y:
x = 4y^2 - 2
Solve for y:
x + 2 = 4y^2
(x + 2)/4 = y^2
± √((x + 2)/4) = y
Note that we have a ± sign because the square root of a positive number can have two values, one positive and one negative.
Therefore, the inverse of y = 4x^2 - 2 is:
x = ± √((y + 2)/4)

The equation of the line of best fit representing the data
on a scatter plot is y = 3.2x + 25. Based on the line of

difference in y-values when the x-values are 20 and 35?
A. 48
B. 73
C. 88
D. 33
48
The line of best fit has the following equation
y = 3.2x + 25
Since the x-values are 20 and 35, we must enter these values into the equation and subtract them to determine the difference in the y-values:
y(20) - y(35) = (3.220 + 25) - (3.235 + 25)
y(20) - y(35) = (64 + 25) - (112 + 25)
y(20) - y(35) = 89 - 137
y(20) - y(35) = -48
For x-values of 20 and 35, 48 is the most logical prediction for the difference in y-values.
Thus, Option (A) 48 is the correct answer.
