Answer:
a. - 45 feet
b. - 18 feet.
Step-by-step explanation:
If we consider the water level as the reference level then the elevation of the fish is - 27 feet, i.e. the fish is 27 feet below the water level.
a. Now, the fish decreases its elevation by 32 feet and then increases its elevation by 14 feet.
Therefore, the new elevation of the fish is (- 27 - 32 + 14) = - 45 feet.
b. Now, if my elevation is 
of the new elevation of the fish then my elevation will be = 
feet. (Answer)
Answer: Good thing you provided the image!
Working down the columns:
C base= 2
D base = 4
C height =3
D height = 2
C area = bh = 8
D area = bh = 8
Step-by-step explanation:
Try thinking about drawing a rectangle around the entire image of C and D, connecting each of the corners (sort of like what is being done for B) and then you can perceive the b and h.
The trick to D is to turn your head 90 degrees (or sideways) so you can see those 4 boxes as the base.
For C the base is the 2 boxes, and going up until you meet the other parallel side you can count 4 boxes.
I usually default to using the side which I can easily count boxes as the base and go from there.
B) 2 (5 + 7) = 2 × 5 + 2 × 7
Distributing the two multiples the five and seven and adds there them together.
Answer: C. -102 + (-25.5)
Answer:
- table: 14, 16, 18
- equation: P = 2n +12
Step-by-step explanation:
Perimeter values will be ...
rectangles . . . perimeter
1 . . . 14
2 . . . 16
3 . . . 18
__
The perimeter of a figure is twice the sum of the length and width. Here, the length is a constant 6. The width is n, the number of rectangles. So, the perimeter is ...
P = 2(6 +n) = 12 +2n
Your equation is ...
P = 2n +12 . . . . . . . . perimeter P of figure with n rectangles.
_____
<em>Additional comment</em>
You may be expected to write the equation using y and x for the perimeter and the number of rectangles. That would be ...
y = 2x +12 . . . . . . . . . perimeter y of figure with x rectangles
