Humphrey needs to mail a package. He weighs it at home as 20.2 ounces. When he gets to the post office, the clerk weighs it at 1

Scrat [10]

Answer:

7.92%

Step-by-step explanation:

Given the following

Weight of package at home = 20.2 ounces.

Weight of the package at the office = 18.6ounces

Decrement = 20.2 - 18.6

percentage error = decrement/wt at home * 100

percentage error = 1.6/20.2* 100

percentage error = 160/20.2

percentage error = 7.92

HEnce the percent error in the weight of the package is 7.92%

Can someone answer each step of this correctly?

About Slope - Intercept Form:

y = mx + b
m is the slope
b is the y-intercept

About Standard Form:

Ax + By = C
A & B & C are integers
A & B are both non-zero
This form is good to use when wanting to find the x & y intercepts of a line

About Point - Slope Form:

Y - Y1 = m (x -X1)
Y1 & X1 is a point on the line
The form allows you to identify the slope & the point on the line

Other Info:

Remember, y comes before the x
An ordered pair from your problem: (-3,1), -3 is x & 1 is y & x is before the y
An ordered pair from your problem: (3,5), 3 is x & 5 is y & x is before the y
For the graph, the vertical line is y

For the graph, the horizontal line is x

Hope this information helps!!! :)

What is the value of x in the equation log5 x = 4 jmap?

steposvetlana [31]

To solve for x we proceed as follows:
from the laws of logarithm, given that:
log_a b=c
then
a^c=b
applying the rationale to our question we shall have:
log_5 x=4
hence
5^4=x
x=625
Answer: x=625
