You are testing two scales for accuracy by weighing two different objects. Use the drop-down menus to complete the statements about the scales' accuracy.
Answers
Answer:
Because the object on scale 1 weighs more than the object on scale 2, each pound of error results in a lesser percent error. Scale 1 was 10 pounds off and scale 2 was 3 pounds off, so scale 1 was 10% off and scale 2 was 12% off.
The object on scale 1 weighs 100 pounds and the object on scale 2 weighs 25 pounds so the object on scale 1 weighs more than scale 2.
Scale 1 error margin: Scale 2 error margin:
= Actual weight - measured weight = 25 - 22
= 100 - 90 = 3 pounds
= 10 pounds
Scale 1 error percentage: Scale 2 error percentage:
= Error margin/ Actual weight = 3/25
= 10/100 = 12%
= 10%
Scale 1 object has less percent error.
Answer:
Fill in Blanks in Caps and Numbers are in ()
Because the object on scale 1 weighs (MORE) than the object on scale 2, each pound of error results in a (LESSER) percent error. Scale 1 was (10) pounds off and scale 2 was (3) pounds off, so scale 1 was (10)% off and scale 2 was (12)% off

Find the slope of the line that passes through (-7, 1.3) and (-7, 14.2)
Answers
Answer:
The slope of the line that passes through (-7, 1.3) and (-7, 14.2) is undefined.
Step-by-step explanation:
Given the points
(-7, 1.3)(-7, 14.2)Finding the slope between (-7, 1.3) and (-7, 14.2):
It is clear that the value of x-coordinate remains the same, no matter what is the value of y is.
In other words, the given line is vertical.
i.e. [x₂ - x₁] = -7 - (-7) = -7+7 = 0
We know that the slope of a vertical line is undefined.
i.e.
Using the slope formula
Slope = [14.2 - 1.3] / [0]
Hence, the slope of the line that passes through (-7, 1.3) and (-7, 14.2) is undefined.

Step-by-step explanation:
Remember that a line is 180 degrees. To find the measure of angle 2 you will take 180-131= 49.
The measure of angle 1 matches to 131 degrees since it is an alternate interior angle.

Area of parallelogram
= Vertical height * Base
= (8m)(6m) = 48m².
The area is 48 square meters.
Answer:
48 square meters
Step-by-step explanation:
First we know there are two triangles the same size and because, the formula is A = 1/2b*h. Therefore, we only have to do the math for one triangle to make up for both triangles.
2*8=16.
Then because, 6 is for both the triangle and the square it would be 4*8=32
32+16=48
48
Therefore, your answer would be 48 square meters.

Answers
Answer:
a) 23x
b) 8n
c) -6y
d) -17w
Explanation:
When combining like terms, if there is an addition operator, add both coefficients and carry the variable over. If there is a subtraction operator, subtract both coefficients and carry the variable over. Remember, you can only combine like terms if the variable, and exponent are the same. The addition and subtraction symbols are examples of an operator used in arithmetic. For example, 9x + 14x could be like adding 9 objects and 14 objects together, you have 23 objects total because 9 + 14 = 23. When you add negative numbers, it is like subtracting. When you subtract negative numbers, it is like adding. Negative just means opposite.
a) 9x + 14x = (9+14)x = (23)x = 23x
b) -2n - 10n = (-2+10)n = (8)n = 8n
c) 8y - 14y = (8-14)y = (-6)y = -6y
d) -6w - 11w = (-6-11)w = (-17)w = -17w
Answer:
a: 23x
b: 8n
c: -6y
d: -17w

Answer:
X= 20 degrees
Step-by-step explanation:
Because all the sides are the same length, we know this triangle is an equilateral triangle. In an equilateral triangle, all the angle measures are the same as well, and the sum of all the angles in a triangle is 180 degrees. So we have the equation:
(3x)3= 180
9x= 180
