Answer:
= -8x +24w +16
Step-by-step explanation:
The factor outside multiplies each term inside parentheses.
-8(x -3w -2) = (-8)(x) +(-8)(-3w) +(-8)(-2)
= -8x +24w +16
Answer:
idk just google it :)
Step-by-step explanation:
1. google it
The pyrite cube is, well, a cube, so it has a side length <em>s</em> such that the area of its base is
<em>s</em> ² = 5.76 cm²
which means
<em>s</em> = √(5.76 cm²) = 2.4 cm
Then its volume is
<em>s</em> ³ = 13.824 cm³
Pyrite is also known as "fool's gold" because it looks a lot like gold. So if gold has a unit price of €785/cm³, then a pyrite cube with volume 13.824 cm³ could be mistaken for a gold cube of the same volume, which would sell for a price of
(€785/cm³) × 13.824 cm³ = €10,851.80
We have to find the number of significant figures in the product of 1.6 cm and 2.4 cm.
Let us first find the product of 1.6 cm and 2.4 cm.
= 3.84 square cm.
Now, we have to determine the number of significant figures in 3.84
The significant digits of a number are the digits have meaning or they contribute to the value of the number. All non-zero digits are significant
, any zeros between significant digits are also significant figures and the trailing zeros to the right of a decimal point are significant figures.
Therefore, in 3.84, there are 3 significant figures in this number.
So, there are 3 significant figures in the product of 1.6 cm and 2.4 cm.
Answer:
False. It is a number between 0 and 1.
