Answer:
Volume equals 60
Step-by-step explanation:
volume = (width)(height)(length)
volume= (2.5)(4)(6)
volume= 60
The amount of glass used is equivalent to the surface area of the glass surfaces.
As the problem is specifying the top of the aquarium is open, we'll assume that it is not included for the surface area calculations.
[tex]A=2 (2.5 \times 4) +2(6\times4)+(6\times2.5)[/tex]
The first term represents the area of two 2.4 x 4 faces of the aquarium. The second term is the area for the two 6 x 4 faces. The last term is for the 6 x 2.5 base of the aquarium, and it is not multiplied by 2 as we are not including the top of the aquarium.
[tex]=2 \times 10 + 2\times24 + 15[/tex]
[tex]=83 \text{ ft}^2[/tex]
The aquarium has a surface area of 83 square feet. Hence, 83 square feet of glass was used to build the tank.

Miss Rivas and Mr. Seipel have homerooms with the same perimeter. Mr. Seipel's homeroom has a width that is 1 1/10 times the width of Miss Rivas' homeroom
Answers
Answer: Unknown
Step-by-step explanation:
Well, we know that Mr. Seipel's homeroom is 11/10 times the width of Miss Rivas' homeroom. Because 11/10 = 1.1, we can multiply Miss Rivas' homeroom width by 1.1 to get Mr. Seipel's homeroom width. We can also divide Mr. Seipel's homeroom width by 1.1 to get Miss Rivas' homeroom width. But, you didn't provide the question in your post.

A fair, 6-sided die is rolled 60 times. Predict how many times it will land on a number greater than 2.
60
40
20
two thirds
Answers
Answer: 40!
Please give brainliest.
Step-by-step explanation:
Let us first diagnose the problem.
There is a die with 6 sides.
Sides: 1,2,3,4,5,6
4 of the 6 sides are greater than 2.
Let us use the theoretical probability formula of
Number of favorable outcomes / Number of possible outcomes.
Favorable outcomes being 4 because there is 4 numbers greater than 2, which is favorable to the outcome we want
Possible outcomes being 6 because the die has 6 sides.
Now lets put this in a fraction:
[tex]\frac{4}{6}[/tex]
Lets multiply our fraction by 60, as we are rolling the die 60 times.
[tex]\frac{4}{6} (60) = 40[/tex]
We got 40! Which basically means 40%.

Triangles ABC and DEC are similar. Side DE is 1.8 feet, side EC is 4 feet, and side BE is 0.8 foot.
Part A: Describe how to draw triangles ABC and DEC separately. Be sure to give the lengths of sides BC, DE, and EC in the description.
Part B: Find side AB. Show each step of your work.
Answers
The lengths of sides BC, DE, and EC in triangle DEC are given as [tex]4[/tex] feet, [tex]1.8 feet,[/tex] and 0.8 foot, respectively. The length of side [tex]AB[/tex] is approximately [tex]3.36[/tex] feet.
What is the line segment?Part A:
To draw triangles [tex]ABC[/tex] and [tex]DEC[/tex] separately, follow the steps below:
Draw a straight line segment DE with length [tex]1.8[/tex] feet.
From point D, draw a line segment DC perpendicular to DE with length 4 feet.
Connect point E and point C with a straight line segment EC.
From point B, draw a line segment BE perpendicular to BC with length 0.8 foot.
Draw a straight line segment BC that intersects line segment DC at point A.
Connect point A and point B with a straight line segment AB.
The lengths of sides BC, DE, and EC in triangle DEC are given as [tex]4[/tex] feet, [tex]1.8 feet,[/tex] and 0.8 foot, respectively.
Part B:
Since triangles [tex]ABC[/tex] and [tex]DEC[/tex] are similar, their corresponding sides are proportional. Let x be the length of side AB. Then we have:
[tex]AB/DE = BC/EC[/tex]
Substituting the given values, we get:
[tex]x/1.8 = BC/0.8[/tex]
Solving for BC, we get:
[tex]BC = 0.8x/1.8[/tex]
Since BC and EC are the two legs of a right triangle DEC, we can use the Pythagorean theorem to find BC:
[tex]BC^2 + EC^2 = DE^2[/tex]
Substituting the given values, we get:
[tex](0.8x/1.8)^2 + 4^2 = 1.8^2[/tex]
Solving for x, we get:
[tex]x = 1.8 * (sqrt(1.8^2 - 4^2)) / 0.8[/tex]
[tex]x \approx 3.36 feet[/tex]
Therefore, the length of side [tex]AB[/tex] is approximately [tex]3.36[/tex] feet.

We need to distribute the ^3 to the 2 and x^4.
(2^3) (x^4)^3
8 (x^4)^3
When an exponent has an exponent, you multiply them.
8 (x^12) ⬅️ we got this by multiplying 4 and 3.
