A block of wood has a mass of 180 grams. It is 10cm long 6cm wide and 4cm thick. What is its volume and density?

1 answer:

8 0

Volume = (length) x (width) x (height) =

(10cm) x (6cm) x (4cm) = 240 cm³

Density = (mass) / (volume) = (180 g) / (240 cm³) = 0.75 gm/cm³ .

➷ Here are the steps to solving that problem:

(2x+1)^2

=(2x+1)(2x+1)

=(2x)(2x)+(2x)(1)+(1)(2x)+(1)(1)

=4x^2+2x+2x+1

=4x^2+4x+1

Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000

vesna_86 [32]

Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000368

mm, while the length of the second strain measures 0.000000064 mm. How much larger is the first strain than the second?

We can figure this out using scientific notation.

$0.000000368 - 0.000000064$

$= 3.04e-7$

Put 3.04e-7 in standard notation.

$0.00000304$

Put 0.00000304 back into scientific notation, instead with a multiply sign.

Move the dot back, making the number in between 1-10.

In this case, we would move it back 7 times.

$3.04$ · $10x^{-7}$

So the answer would be A.

You would do 17 times 5.5 = 93.5, so the volume of the ice cream cone would be 93.5 centimeters. I’m assuming that’s the right answer but you might want to get a second opinion.
