Answer:
b. – 0.4(x + 1.6) = 1.6
Step-by-step explanation:
Answer: 1.018
Step-by-step explanation:
The pH level of a substance indicates the concentration of hydrogen ions (
) in a solution and is calculated by:
In this case the hydrogen ion concentration is 
, where
. Hence:
This means this new substance is acid
Let 
be the area of the sector in the larger circle (radius 12 cm) whose central angle is subtended by the labeled arc with measure 45 deg, and let 
be the area of the sector in the smaller circle (radius 8 cm) with the same central angle. The area you want is 
.
We have
So the area of the shaded region is 
.
Answer:
Option B.
Step-by-step explanation:
Option A. "The line constructed through point P that is parallel to line B."
Since parallel lines never intersect each other, a line intersecting line AB at point P will not be parallel.
Therefore, Option (A) is incorrect.
Option (B). "The line constructed through point P that is perpendicular to line AB."
Since the angle between line AB and a line constructed through point P has been given as 90°, line through point P will be perpendicular to AB.
Therefore, Option (B) is the answer.
Option C. "The line constructed through point P that intersects line AB at two different points."
Since, two perpendicular lines intersect each other at only one point, the line constructed from point P will not intersect line AB at two different points.
Therefore, Option C is not correct.
Answer:
The answer is 816
Step-by-step explanation:
16 times 4 = 64
800 times 4 = 3200
3200 + 64 is equal to 3,264
This is what I got as my answer.
Hope this helps! :)
