Gold's volume is 1.61 cubic centimeters.

Aluminium's mass is 26.981539 u

Copper's volume is 1.5 mL

Marble's density 2711 kg

Teak's density is 41 lbs (might be wrong sorry if it is)

Concrete's Volume is Calculating the volume for concrete requires using three dimensions: length times width (which is area) times the height (thickness) or L x W x H. If you are using feet as your standard unit of measurement, this formula will give you the volume of concrete in cubic feet.

Which of the following is a soultion to the quadratic equation below x^2 - 3x - 54 =0

Answers

Answer:

9 or -6

Step-by-step explanation:

To solve, I would suggest factoring.

You need to find two numbers which can be multiplied for 54 and also combined in some way to get 3. In this case, 9 and 6 are perfect.

x^2-3x-54=0\n(x-9)(x+6)=0

Next, you can set both of your terms equal to zero to find your possible solutions.

x-9=0\nx=9\n

or

x+6=0\nx=-6

What 7.3087 rounded to the nearest thouaanth

Answers

7.309
The thousandth is third number to the right of the decimal. We round 5+ up and 4- we round down. 
So we round the decimal into third place, the fourth place is the 7 so we round that up, and we get 7.309
If you round 7.3087 to the nearest thousandth it would be 7.3090.

Julian wrote this number pattern on the board 3,10,17,24,31,38 which of the numbers in Julian's pattern are composite numbers

Answers

The numbers in Julian's pattern are composite numbers are 10,24,and 38.

What is composite numbers?

A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.

here, we have,

3,10,17,24,31,38

Now, we get,

because 10 divided by 2 equals 5 so it's composite

because 10 times 1 isn't the only way to get the number 10,

same thing for numbers 24 and 38, 24 divided by 2 equals 12, 24 divided by 3 equals 8,24 divided by 4 equals 6

so it's composite,

and 38 divided by 2 equals 19.

Hence, The numbers in Julian's pattern are composite numbers are 10,24,and 38.

12.63

Compare 6 and 3. 6 is larger so therefore 12.6666666 is larger. (You also need to compare the tenths place too, but these happen to have the same tenths place, .6.
