The mass of lab sample A is 2.4 x 10^-2 kg. The mass of lab sample B is 3.6 x 10^2 kg. Given that information, Jason says that sample B is 15 times the mass of sample A. Narissa asserts that sample B is 15,000 times that of sample A. Julius states that sample B is 1.5 times greater than sample A.
Compare the masses of the two samples to decide who is correct. State which person is correct and explain your answer using mathematics.
Narissa is right sample B is 15,000 times that of sample A
What is mass?The quantity of matter that any object contains is called the mass of the body.
It is given that:-
The mass of lab sample A is 2.4 x 10^-2 kgThe mass of lab sample B is 3.6 x 10^2 kgSo the mass will be given as:-
[tex]\dfrac{B}{A}=\dfrac{3.6\times 10^2}{2.4\times 10^{-2}}[/tex]
[tex]\dfrac{B}{A}=15000[/tex]
B = 15000 B
Therefore Narissa is right sample B is 15,000 times that of sample A

5. A pyramid with a triangular base has a volume of 80 cubic meters and a base
area of 20 square meters. Find the height of the pyramid.
The height of the triangular pyramid will be equal to H=12 feet.
What is a triangular pyramid?A triangular pyramid is a pyramid having triangular faces the other sides of the pyramid are simliar triangles.
It is given that:-
The Volume of the pyramid=80 cubic meters
The Base area of the pyramid=20 square meters
The height of the pyramid=?
We know that the volume of a pyramid is given as:-
V=(1÷3)x Base area x height
V=(1÷3)x20 x H
H=(80x30)÷20
H=12 feet
Hence the height of the triangular pyramid will be equal to H=12 feet.

pls help find the lateral surface area of this prism in square centimeters, i give brainliest!! :)
Answer:
1232 square meters
Step-by-step explanation:
The lateral surface area are all the rectangles.
1st rectangle:
A = lw
A = 25(22)
A = 550
2nd rectangle:
A= lw
A = 7(22)
A = 154
3rd rectangle:
A = lw
A = 24(22)
A = 528
Add the areas together.
550 + 154 + 528 = 1232

The catalog is advertising a stack of these cups that is 95 cm tall. Lori says, “That must be a misprint because a stack of that height is not possible.”
Do you agree or disagree with Lori? Explain your reasoning.
Answer:
in particular, the relationship between height of stack and number of cups yields a non-whole number of cups, corresponding to a height of 95 cm. In this context, that is not possible because we do not allow for parts of cups.
Step-by-step explanation:
It is possible for a stack of cups to be 95 cm tall depends on the size and shape of the cups and how they are stacked.
What is Area of Rectangle?The area of Rectangle is length times of width.
Assuming the cups are all the same size and shape, the height of the stack would depend on the number of cups in the stack.
if each cup is 5 cm tall, a stack of 19 cups would be 95 cm tall (19 x 5 = 95).
If the cups are irregularly shaped or have varying sizes, it may be more difficult to stack them in a way that reaches 95 cm in height.
It is possible for a stack of cups to be 95 cm tall depends on the size and shape of the cups and how they are stacked.
It is possible for some stacks of cups to reach this height, but not necessarily all stacks of cups.
Hence, it is possible for a stack of cups to be 95 cm tall depends on the size and shape of the cups and how they are stacked.

One month Jessica rented 4 movies and 8 video games for a total of $61. The next month she rented 2 movies and 3 video games for a total of $25. Find the rental cost for each movie and each video game.
Answer:
A movie costs $4.25 and a video game $5.5.
Step-by-step explanation:
Step 1: Form the equations.
Let m be the price of a movie and v the price of the video game.
First equation: One month Jessica rented 4 movies and 8 video games for a total of $61.
[tex]4m + 8v = 61[/tex]
Second equation: The next month she rented 2 movies and 3 video games for a total of $25.
[tex]2m + 3v = 25[/tex]
Step 2: Solve the system of equations.
[tex]\text{(1.) } 4m + 8v = 61\\\text{(2.) } 2m + 3v = 25[/tex]
I'm going to solve them by elimination. I'll multiply the second equation with two so I get 4m.
[tex]\text{(1.) } 4m + 8v = 61\\\text{(2.) } 4m + 6v = 50[/tex]
Now I'm going to subtract the second equation from the first.
[tex](4m + 8v) - (4m + 6v) = 61 - 50[/tex]
And solve.
[tex]8v- 6v = 61 - 50\\2v = 11\\v = \frac{11}{2}\\v = \$5.5[/tex]
Now let's insert v back in second equation to get m (nicer numbers, you can insert in first too if you want).
[tex]4m + 8v = 61\\4m + 8(5.5) = 61\\4m + 44 = 61\\4m = 61 - 44\\4m = 17\\m = \frac{17}{4}\\m = \$4.25[/tex]

Answer:In the diagram, there are 28 tiles. You can do that with easy multiplication or just counting. Each square length is 1.5 feet, or 18 inches. You get that by multiplying 12 by 1.5. The area of a square is 324 inches, found by multiplying 18 by 18. Divide 324 by the area of a tile, 36 (6*6), to get 9. There are 9 tiles in each square. Multiply 9 by 28 to get... 252
