The required volume of the given aquarium is given as 7 cubic feet.
What is volume?Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.
here,
The volume of an aquarium can be found by multiplying its length, width, and height.
Given the length of the aquarium as 7/2 feet, the width as 4/3 feet, and the height as 3/2 feet, the volume can be calculated as:
Volume = 7/2 × 4/3 × 3/2
= 7 cubic feet
Therefore, the volume of the aquarium is 7 cubic feet.

Write an equation in slope-intercept form.
Given:
The table of values.
To find:
The equation in slope intercept form.
Solution:
From the given table it is clear that the line passes through the points (5,17), (8,41) and (12,73).
Consider any two points from the table, i.e., (5,17) and (8,41). So, the equation of line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-17=\dfrac{41-17}{8-5}(x-5)[/tex]
[tex]y-17=\dfrac{24}{3}(x-5)[/tex]
[tex]y-17=8(x-5)[/tex]
[tex]y=8x-40+17[/tex]
[tex]y=8x-23[/tex]
Therefore, the equation of line in slope intercept form is [tex]y=8x-23[/tex].
Hey, can you guys help me out with this question? I need the workings too.( find the surface area )
▪︎Side 15 cm, 18 cm and x cm form a right angle triangle.
We know that :
[tex] =\tt {hypotenuse}^{2} = {leg}^{2} + {leg}^{2} [/tex]
Which means :
[tex] =\tt {15}^{2} + {x}^{2} = {18}^{2} [/tex]
[tex] =\tt 225 + {x}^{2} = 324[/tex]
[tex] =\tt {x}^{2} = 324 - 225[/tex]
[tex] = \tt {x}^{2} = 99[/tex]
[tex]\color{plum} =\tt x = 9.9 \: cm[/tex]
Thus, x (radius) = 9.9 cm
We know that :
[tex]\color{hotpink}\tt \: Surface \: area \: of \: cone \color{plum}=\pi r(r + \sqrt{ {h}^{2} + {r}^{2} } [/tex]
Then, the surface area of this cone :
[tex] = \tt3.14 \times 9.9 \times( 9.9 + \sqrt{ {15}^{2} + {9.9}^{2} } )[/tex]
[tex] =\tt 3.14 \times 9.9 \times( 9.9 + \sqrt{323.01} )[/tex]
[tex] =\tt 3.14 \times 9.9 \times (9.9 + 18)[/tex]
[tex] =\tt 3.14 \times 9.9 \times 27.9[/tex]
[tex] = \tt31.09 \times 27.9[/tex]
[tex]\color{plum} =\tt\bold{ 867.4 \: cm}[/tex]

$10,000 form the bank at a 9% rate for 5 years. How much interest
will you pay on this loan?
Answer:
$ 4,500.00
Step-by-step explanation:
I = $ 4,500.00
Equation:
I = Prt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 9%/100 = 0.09 per year,
then, solving our equation
I = 10000 × 0.09 × 5 = 4500
I = $ 4,500.00
The simple interest accumulated
on a principal of $ 10,000.00
at a rate of 9% per year
for 5 years is $ 4,500.00.

Which histograms are approximately symmetric and bell shaped?
Answer:
B and E
Step-by-step explanation:
im pretty sure what you have is correct
The correct histograms that are approximately symmetric and bell-shaped are - histograms B, C, and E because they are symmetric and bell-shaped.
A histogram is a convenient form or graphical representation of the frequency distribution of numerical data by means of rectangles. These histograms are found in different shapes and symmetries.
Bell-shaped curve:
if a histogram resembles or looks like a “bell” by joining the interval of rectangles in a curve and has one single peak in the middle of the distribution.In the given histograms only histogram shows a bell-like curve when joining the middle point of rectangles of distribution and also present in symmetry.in the image attach approximate curves are form you can see if it is bell shape and symmetric.Thus, the correct answer is - Histograms B, C, and E.

I need help. So it says to find the shaded area, and I'm not really good a things like this
Answer:
86 cm²
Step-by-step explanation:
1) Calculate the area of the square
[tex]A=lw\\A=20*20\\A=400[/tex]
Therefore, the area of the square is 400 cm².
2) Calculate the area of the circle
[tex]A=\pi r^2\\[/tex]
[tex]\pi[/tex] we can substitute with 3.14. To find the radius, we divide the diameter of the circle by 2. 20 cm is the diameter of the circle, so therefore, its radius is 10 cm.
[tex]A=3.14*10^2\\A=3.14*100\\A=314[/tex]
Therefore, the area of the circle is 314 cm².
3) Subtract the area of the circle from the area of the square
[tex]A=400-314\\A=86[/tex]
Therefore, the area of the shaded region is 86 cm².
I hope this helps!
Step-by-step explanation:
Given,
One side of the square = 20 cm
Therefore, Area of the square = side × side
= 20 cm × 20 cm
[tex] \: \: \: \: \: \: \: \: = 400 {cm}^{2} [/tex]
Also, known that
One side of the square = Diameter of the circle = 20 cm
So, radius of the circle = 20/2 cm = 10 cm
Therefore, area of the square
[tex] \: \: \: \: \: \ \: \: \: \: = \pi{r}^{2} [/tex]
[tex] = 3.14 \times {(10cm)}^{2} [/tex]
[tex] = 3.14 \times 100 {cm}^{2} [/tex]
[tex] = 314 {cm}^{2} [/tex]
Hence, area of the shaded region is
= Area of the square. - Area of the circle
[tex] = 400 {cm}^{2} - 314 {cm}^{2} [/tex]
[tex] = 86 {cm}^{2} (ans)[/tex]
