You are using a beaker to measure volume. the beakers graduation begin at 20ml and in indicate every 10ml up to 80 ml. the botto
dolphi86 [110]

Answer:

b) 47ml

Explanation:

The beaker would look like this:

60 mL

50 mL

-------  The bottom of the meniscus is here

40 mL

30 mL

So <u>we have between 40 and 50 mL</u>. There are 10 mL of "distance" between those two values, and three fourths of that difference is (10 * 3/4) 7.5 mL.

So <em>the volume is 47.5 mL</em>, but because the measurement instrument (the beaker) does not handle decimals, the value we should report is 47 mL.

Can someone help I’ll give s you BRAINLIST !!! I just need help in these question btw it’s science and 6th grade work plzz help
morpeh [17]

Answer:

     More than 2,000 Years Ago, the Greek philosopher Aristotle suggested a model of the solar system. Aristotle's model was geocentric, or Earth-centered. In the model. the sun, stars, planets revolved around the Earth. In 150 AD an astrologer named Ptolemy began to support Aristotle's geocentric model.

    In 1543 AD, an astronomer named Copernicus proposed a heliocentric model of the solar system. In this model, the planets revolve around the sun. Due to the invention of the telescope, the solar system could be explored in more detail. Galileo used the telescope to support Copernicus's theory of the sun being the center of the universe.

    In the late 1500's, Kepler developed a law that explained planetary motion. Kepler's law is so accurate we still use them today.

How many square centimeters are in an area of 8.50 inch^2
Paha777 [63]

Explanation:

Given parameters:

  Dimension = 8.5in²

we are to convert from in² to cm²

 in² = in x in

 cm² = cm x cm

   1 in = 2.54cm

Using dimensional analysis;

   8.5in² x \frac{2.54cm}{1in}  x \frac{2.54cm}{1in}

        =  54.84cm²

We solved this problem using dimensional analysis where we multiplied the unit with 1.
