You estimate that a baby pig weighs 20 pounds. The actual weight of the baby pig is 16 pounds. Find the percent error

Answers

Answer 1
Answer:

Answer:

Percentage error is 25%.

Step-by-step explanation:

Given : Estimated weighs of a baby pig = 20 pounds

             Actual weight of the baby pig = 16 pounds

To find : The percentage error

Solution : Formula to find percentage error

\frac{\text{Estimated weight}- \text{Actual weight}}{\text{Actual weight}}* 100

Putting values in formula,

=(20-16)/(16)* 100

=(4)/(16)* 100

=(1)/(4)* 100

=25%

Therefore, Percentage error is 25%.
Answer 2
Answer: Your estimate of the baby pig's weight is 2 pounds. However the actual weight of it is only 16 pounds.
Let's solve for the percentage error of this.
=> 20 - 16 = 4 pounds
=> 4 / 16 = 0.25
=> 0.25 * 100% = 25%
Thus, you added 25% of the baby pig's weight

Hannah and Francine have $120. Hannah and Peter have $230. Peter has six times as much as Francine. How much does Hannah have?

Answers

Answer:

The amount that Hannah has is $98

Step-by-step explanation:

Let

x-----> amount that Hannah has

y ----> amount that Francine has

z ----> amount that Peter has

we know that

x+y=120 ----> equation A

x+z=230 ----> equation B

z=6y -----> equation C

substitute equation C in equation B

x+6y=230 ----> equation D

we have

x+y=120 ----> equation A

x+6y=230 ----> equation D

Solve the system of equations A and D by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The solution is the point (98,22)

see the attached figure

Find the value of z

z=6y ----> z=6(22)=132

therefore

The amount that Hannah has is $98

The amount that Francine hasis $22

The amount that Peter has is $132

Step-by-step explanation:

Use\n\n(a^n)^m=a^(nm)\n\n(a^n)/(a^m)=a^(n-m)\n------------------\n\n((x^(25))^(-6))/((x^(-3))^(48))=(x^((25)(-6)))/(x^((-3)(48)))=(x^(-150))/(x^(-144))=x^(-150-(-144))=x^(-150+144)=x^(-6)
