Answer: The volume is 480 in^3

Step-by-step explanation:

v= lwh

v= 12 * 5 * 8

v= 480 in^3

Answer:

Volume of the rectangular prism = $480in.^{3}$

Step-by-step explanation:

Formula for the volume of a rectangular prism= Ah, where A= base area

& h= height

Base area(A)= Length×Width

= 12in.×8in.

= $96in.^{2}$

Since height=5in.,

Volume= $96in.^{2}$ ×5in.

= $480in.^{3}$

The base length for each parallelogram is $1\frac{5}{8}$ yards.

Step-by-step explanation:

Step 1:

The area of a parallelogram is given by the product of its base length and height.

So the parameters needed to determine the area of a parallelogram are its base length and its height.

We must convert the mixed fractions into improper fractions. To do that we multiply the number with the denominator and add with it the numerator whereas the denominator remains the same.

To convert the fraction $3\frac{5}{7} = \frac{(3)(7)+5}{7} = \frac{26}{7}$ which is the area.

To convert the fraction $1\frac{1}{7} = \frac{(1)(7)+1}{7} = \frac{8}{7}$ which is the height of the parallelogram.

Step 2:

Assume the length of the parallelogram is x.

So the area of the parallelogram $= (x)(\frac{8}{7} ) = \frac{26}{7} .$

$x = (\frac{26}{7}) (\frac{7}{8} )= \frac{26}{8} .$ This is the base length for both parallelograms.

So each parallelograms base length $= \frac{\frac{26}{8} }{2} = \frac{13}{8} = 1\frac{5}{8}.$

So the base length for each parallelogram is $1\frac{5}{8}$ .

If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalen

Alex_Xolod [135]

The answer would be D.
The only you thing you have to do is alter the first equation to isolate the x. You do that by moving the 4y to the other side, giving you:
x=(-4y-9)
Then you simply insert your new value for x into the second equation.
Hope this helps. :)

Let ∠X and ∠Y be complementary. If sin(X) = 3/5

statuscvo [17]

Since they are complementary
x + y = 90

Sin(o) = Cos (90-0)

Therefore, Cos x = Sin y = 4/5 [ Because x and y are complementary]
