Between the years of 1947 and 1956, earthenware jars containing what are known as the dead sea scrolls were found in caves along the coast of
jerusalem in the dead sea. upon radiometric testing, it was found that the scrolls were wrapped in material that contained about 79 percent of
the original carbon-14. archeologists estimated that the scrolls are about 1,900 years old. are they right?
question 1
using the half-life of carbon-14 (5,730 years), prove or disprove this estimate age. describe how you are testing this hypothesis.

9 x 8 divided by (5-3)=36

i think it would be 42cm

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
