An engineer estimated the weight of a steel beam to be 600 pounds. the actual weight of the beam was 639 pounds. find the absolute error and the percent error of the engineer's estimate. if necessary, round your answers to the nearest tenth.

Absolute error = 39 pounds

Percent error = 6.10%

Step-by-step explanation:

We are given that the actual weight of the beam was 639 pounds while its estimated weight was 600 pounds.

We can find the absolute error by subtracting the original weight from the estimated weight.

Absolute error = 639 - 600 = 39 pounds

Next, we will use the following formula to find the percent error.

Percent error = (Estimated value - actual value / actual value) * 100

Percent error = 639 - 600 / 600 * 100 = 6.10%

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
