Answer:

40.0 mL

Explanation:

The volume of a substance when given the density and mass can be found by using the formula:

Volume = mass/density

From the question:

mass = 420 g

density = 10.5 g/cm³

The volume is:

Volume = 420/10.5

We have the final answer as

40.0 mL

How to solve it I am very confused
a_sh-v [17]

Answer:

Answer:

53/12+28/3=13/34

Solution with Steps

53/12+28/3=?

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(53/12, 28/3) = 12

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(53/12×1/1)+(28/3×4/4)=?

Complete the multiplication and the equation becomes

53/12+112/12=?

The two fractions now have like denominators so you can add the numerators.

Then:

53+112/12=165/12

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 165 and 12 using

GCF(165,12) = 3

165÷3/12÷3=55/4

The fraction

55/4

is the same as

55÷4

Convert to a mixed number using

long division for 55 ÷ 4 = 13R3, so

55/4=13 3/4

Therefore:

53/12+28/3=13/34

Solution by Formulas

Apply the fractions formula for addition, to

53/12+28/3

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(495,36) = 9

49/5÷93/6÷9=554

Convert to a mixed number using

long division for 55 ÷ 4 = 13 R3, so

554=1334

Therefore:

53/12+28/3=13 3/4

So I Believe 13 3/4  or 55/4

I hope this isn't wrong.
