Jessie estimated the weight of his cat to be 12 pounds. The actual weight of the cat is 15 pounds.
Studentka2010 [4]

Answer:

20%

Step-by-step explanation:

% of error is given by the following formula:

% Error = \frac{|\textrm {Approx Value  - Exact Value}|}{\textrm {Exact Value}} \times 100

Now, Jessie estimated the weight of his cat to be 12 pounds i.e. Approximate value is 12 pounds.

Again, The actual weight of the cat is 15 pounds i.e. the exact value is 15 pounds.

Therefore, the % error = \frac{|12 - 15|}{15} \times 100 = \frac{3}{15} \times 100 = 20% (Answer)

hat is the value of y? Enter your answer in the box. A triangle with angle measures thirty-seven degrees and seventy-nine degree
lana [24]

Answer:

The answer is 64 degrees.

Step-by-step explanation:

The sum of all three angles of any triangle is 180 degrees. That means we have to add 37 and 79 to get 116. Subtract 180 by 116 to get 64. 64 degrees is the measure of the missing angle.


I hope this helped! :-)
