For this case what we can do is the following rule of three:
24.3 -----> 130%
x ---------> 100%
We clear the value of x:
x = (100/130) * (24.3)
x = 18.7 grams
Answer:
the current mass of the object was:
x = 18.7 grams
Answer: First option is correct.
Step-by-step explanation:
Enrollment month Actual Predicted Residual
January 500 8 4
February 400 15 -1
March 550 15 -1
April 13 12 -1
May 16 17 -1
June 14 15 -1
Since we know that
Residual value = Actual value - Predicted value
Sum of residuals is given by
since we can see that sum of residual is more than 0.
So, it can't be a good fit .
Hence, No, the equation is not a good fit because the sum of the residuals is a large number.
Therefore, First option is correct.
Answer:
Option F is correct, i.e. "rotating 90° counterclockwise around point C."
Step-by-step explanation:
Given is the regular octagon PQRSTVWZ with its center at point C.
To map octagon PQRSTVWZ onto itself, we must provide such a transformation that should not change the size or coordinates of the vertices.
We can not use Translations, Reflections, and Dilations because they will change size and coordinates.
We can use only Rotations and that should be about the center C of the regular shape.
About center point C, and rotations of 90° does not change the orientation of the regular octagon, Both images would overlap each other.
Hence, option F is correct, i.e. "rotating 90° counterclockwise around point C."
<span>Total mass contains 320g copper. How many parts of 16g copper are there of the total mass of 320g copper? 320/16 = 20. There are 20 portions of 16g copper.
(320/16) * 3 = 60g
There are 60g of zinc in the compound.</span>
