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.

aliina [53]

Answer:

A. 14040 cubic inches

B. 61 gallons

Step-by-step explanation:

The volume of a cuboid is given by the formula ...

V = LWH

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.

One gallon is 16 cups, so 976 cups is 976/16 = 61 gallons.

976 cups equals 61 gallons.

_____

<em>Additional comment</em>

One gallon is 231 cubic inches, so the volume of the tank is actually about 972 cups, or 60.8 gallons.

Given the function <br> g(x) = 2x + 4 find 9(2), 9(4), and g(10)

ankoles [38]

You would have to plug in the numbers in the equations. I will do one and you can do the rest:)
g(x) = 2x + 4
g(10) = 2(10) + 4
g(10) = 20 + 4
g(10) = 24 <— That is the answer for g(10)
Now you plug in the other ones and solve!
Hope I helped:)

How many 3/4s are in 3 2/4

MArishka [77]

Answer:

the answer is 3

Step-by-step explanation:

First change the whole number (3) to quaters or fraction

3x $\frac{4}{4}$ = $\frac{12}{4}$

Now, add

$\frac{2}{4}$ + $\frac{12}{4}$ = $\frac{14}{4}$ Since, we have the same common denominator

now divide

14÷4 =3.5 = 3 $\frac{2}{4}$

Therefore, there are 3 of 3/4 with a remainder of $\frac{2}{4}$ in 3 $\frac{2}{4}$ .
