The line is 7 units long. Add the two equations together and set equal to 7:

7x-1 + 2x-1 = 7

Combine like terms:

9x-2= 7

Add 2 to both sides:

9x= 9

Divide both sides by 9:

X= 1

You have a small marble statue of Mozart that is 10 inches tall and is made of 16 cu. inches of marble. The original statue in V
vagabundo [1.1K]

Answer:

0.08 cubic feet.

Step-by-step explanation:

You have a small marble statue of Mozart that is 10 inches tall and is made of 16 cu. inches of marble.

The original statue in Vienna is 7 feet tall.

First we will convert this to inches as one relation is given in inches.

1 feet = 12 inches

7 feet = 12\times7=84 inches

Let the amount of marble used for 84 inches statue be = x

We can relate both the conditions in the following way:

\frac{10}{16} =\frac{84}{x}

10x=16\times84

10x=1344

x = 134.40 cubic inches

Now, 1 cubic inch = \frac{1}{1728} cubic foot

So, 134.40 cubic inches = \frac{134.40}{1728} cubic foot

= 0.0777 cubic feet rounding to 0.08 cubic feet.

madam [21]
Cathy may not understand that you look at the neighbor of your number which is seven and anything with the number 4 or less will stay the same. Which would get you 1,200 anything 5 or more you will raise the number which means that the number 1,275 rounded to the nearest hundredth would be 1,300.
