The procedure for representing the product 
is described as following:
1) Draw the distance of the first negative number.
2) Extend the distance by the magnitude of the second negative number.
3) Draw the distance of the reflection of the result found in 2).
In the number line <em>negative</em> numbers represent <em>leftward</em> distances. The product of a <em>negative</em> number and a <em>positive</em> number is equal to the distance of the <em>negative</em> one by the number of times such distance is repeated. In addition, we know by algebra that the product of two <em>negative</em> numbers equals a positive number, so we know that distance becomes <em>rightwards</em> due to reflection on the former line segment.
The procedure is described as following:
1) Draw the distance of the first negative number.
2) Extend the distance by the magnitude of the second negative number.
3) Draw the distance of the reflection of the result found in 2).

Answer:
Percent error = 2%
Step-by-step explanation:
Given:
Expected value = 250
Actual value = 255
Find:
Percent error
Computation:
Percent error = [(Actual value - Expected value)/Expected value]100
Percent error = [(255 -250) / 250]100
Percent error = 2%
Answer:
arc YZ = 59°
Step-by-step explanation:
Since XZ is a diameter then ∠ XAZ = 180°
∠XAY + ∠ YAZ = ∠ XAZ , substitute values
11w + 5w + 4 = 180, that is
16w + 4 = 180 ( subtract 4 from 180 )
16w = 176 ( divide both sides by 16 )
w = 11
Thus ∠ YAZ = 5w + 4 = 5(11) + 4 = 55 + 4 = 59°
The arc YZ is the measure of the central angle it subtends, thus
arc YZ = 59°
Answer:
31.0 grams.
Step-by-step explanation:
According to the given information
Half-life of a substance = 37 years
Initial amount = 202 gram
The exponential function for half-life of a substance is
where, A₀ is initial amount, t is time and h is half life.
Substitute A₀=202 and h=37 in the above function.
We need to find the amount of the substance remaining after 100 years.
Substitute t=100 in the above function.
Round the answer to the nearest tenth.
Therefore, the amount of the substance remaining after 100 years is 31.0 grams.
