You are designing a large rectangular fish tank for your tropical fish. The length will be 1 yard 3 inches, the width will be 1.5 feet, and the height will be 20 inches.
Part A
Find the volume of the fish tank in cubic inches.
The volume is
cubic inches.
Part B
Your math teacher tells you that your fish tank will have a capacity of about 976 cups. You have a total of 30 tropical fish. For them to flourish in a fish tank, there needs to be an average of 2 gallons of water for each fish.
Convert 976 cups to gallons.
976 cups equals
gallons.
Answer:
A. 14040 cubic inches
B. 61 gallons
Step-by-step explanation:
The volume of a cuboid is given by the formula ...
V = LWH
__
A.One yard is 36 inches, so 1 yard 3 inches is 36 +3 = 39 inches.
One foot is 12 inches, so 1.5 ft = 1.5×12 = 18 inches.
The volume of the fish tank is ...
V = (39 in)(18 in)(20 in) = 14,040 in³
The volume is 14,040 cubic inches.
__
B.One gallon is 16 cups, so 976 cups is 976/16 = 61 gallons.
976 cups equals 61 gallons.
_____
Additional comment
One gallon is 231 cubic inches, so the volume of the tank is actually about 972 cups, or 60.8 gallons.

Answer:
x=10
y=[tex]10\sqrt{3}[/tex]
Step-by-step explanation:
Since there is a 30 degree angle, it is a special right triangle, 30 60 90 triangle. The shorter leg represents "a," the longer leg represents "a√3", and the hypotenuse represents 2a.
The triangle has a hypotenuse of 20 and we are trying to find x and y. x=10 because x is the opposite side of 30 degrees and x is half of the hypotenuse. y=[tex]10\sqrt{3}[/tex] because we already know the x value and y is opposite of 60 degrees. As mentioned before, the longer leg represents a√3.

Step-by-step explanation:
Imagine a triangle with two of the corner points being the points (5,5) and (8,1)
The length and width would be 3 and 4 to find the hypotenuse (distance) do
3^2+4^2=x^2

[tex]here \: is \: your \: answer...[/tex]
Step-by-step explanation:
Let (x1,y1) = (5,5) and (x2,y2) = (8,1)
By using distance formula,
[tex]d \: = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } [/tex]
[tex]d = \sqrt{ {(8 - 5)}^{2} + {(1 - 5)}^{2} } [/tex]

The percentage of the runner from team B that finishes the race is 21.4%
How to find the percentage that finish the race from team B?
Team A and Team ran a race. Team A had 28 runners and Team B also had 28 runners.
4 runners from team A finishes the race while 12 runners from team B finishes the race.
Therefore, the percentage from team B that finishes the race can be calculated as follows.
percentage from team B that finishes = 12 / 56 × 100
percentage from team B that finishes = 1200 / 56
percentage from team B that finishes = 21.4285714286
percentage from team B that finishes = 21.4%

Mieko bought 2 gallons of paint. She used 1/4 of the paint in her bedroom, 3 quarts in the hallway, and the rest of the paint in the living room. How many quarts of paint did she use in the living room?
A: 3 Quarts
B. 8 Quarts
C. 10 Quarts
D. 12 Quarts
=======================================================
Explanation:
1 gallon = 4 quarts
2 gallons = 8 quarts
1/4 of 8 quarts = 2 quarts
She used 2 quarts for her bedroom and 3 for the hallway. Therefore, she used 2+3 = 5 quarts total.
That leaves 8 - 5 = 3 quarts for the living room.
Answer:
A: 3 Quarts
Step-by-step explanation:
1 gallon = 4 quarts
1/4 of 2 gallons = 1/4 × 2
= 1/2 gallon
⇒ 1/2 gallon = 2 quarts
Therefore, Mieko used 2 quarts of paint to paint her bedroom.
If she used 3 quarts to paint the hallway, then
⇒ total number of quarts used = 2 + 3 = 5 quarts
As she bought a total of 2 gallons of paint:
⇒ 2 gallons = 2 × 4 = 8 quarts
Therefore the remaining unused paint (to paint the living room) is:
⇒ total paint - used paid = 8 quarts - 5 quarts
= 3 quarts

Let's find the raidus from the area formula.
200.96 = π · r^2
Divide both sides by π !
64 = r^2
square root both sides
r = 8.
Now since we know the raidus we can find the circumferewnce.

Cam's Cupboard grocery store is having a sale on canned goods. Tiana decides to stock up
and purchases 12 cans of soup. During the sale, cans of soup sell for $0.55 les than full
price. Tiana pays a total of $13.20 for the cans of soup.
Which equation can you use to find the amount, f, each can of soup costs at full price?
0.55(f - 12) = 13.20
12(f - 0.55) = 13.20
0.55f - 12 = 13.20
12f - 0.55 = 13.20
How much does each can of soup cost at full price?
$
Answer:
1.65
Step-by-step explanation:
equation will be 12(f−0.55)=13.20
12f−6.6=13.20
12f = 19.8
f = 19.8/12 = 1.65
So, each can of soup at full price is $1.65.

For F(x)=3x+4 and g(x)= x^2-3x, find g(f(x)).
Answer:
g(f(x)) = 9x² + 15x + 4
Step-by-step explanation:
Given :
⇒ f(x) = 3x + 4
⇒ g(x) = x² - 3x
=============================================================
Solving :
⇒ g(f(x))
⇒ g(3x + 4) = (3x + 4)² - 3(3x + 4)
⇒ g(3x + 4) = (3x)² + 2(3x)(4) + (4)² - 9x - 12
⇒ g(3x + 4) = 9x² + 24x + 16 - 9x - 12
⇒ g(f(x)) = 9x² + 15x + 4
