A box is 3 inches by 2 feet by 10 yards. How many cubic inches are in the box? How many cubic yards are in the box? (Show all wo
IceJOKER [234]

Answer:

There are <u>25920</u> cubic inches and <u>0.56</u> cubic yards in the box.

Step-by-step explanation:

Given:

The dimensions of the box are 3 in by 2 ft by 10 yd.

Convert all in inches.

We know that, 1 ft = 12 in

So, 2\textrm{ ft} = 2\times 12 = 24\textrm{ in}

Also, 1 yd = 36 in

So, 10\textrm{ yd} = 10\times 36 = 360\textrm{ yd}

Now, volume of the box in cubic inches is given as:

V=3\times 24\times 360=25920\textrm{ }in^{3}

Now, we know that,

1\textrm{ in} = \frac{1}{36}\textrm{ yd}\\1\textrm{ }in^{3}=\frac{1}{36^{3}}\textrm{ }yd^{3}

Therefore,

25920\textrm{ }in^{3}=25920\times \frac{1}{36^{3}}= 0.56\textrm{ }yd^{3}

So, there are <u>25920</u> cubic inches and <u>0.56</u> cubic yards in the box.

Write the first three terms in the following sequences. Identify them as arithmetic or geometric
lara [203]

Answer:

10, 1, 0.1, 0.01

It is a geometric sequence

Step-by-step explanation:

A(n + 1) = A(n) ÷ 10  for  n ≥ 1  and  A(1) = 10

A(1+1) = A(2) = A(1) / 10 = 10 / 10 = 1

A(2+1) = A(3) = A(2) / 10 = 1 / 10 = 0.1

A(3+1) = A(4) = A(3) / 10 = 0.1 / 10 = 0.01

It corresponds to a geometric sequence, which is defined by its starting number a (10), the common factor r (0.1) and the number of terms S.
