Answer:
The whale is at a depth 120 feet below the sea level.
Step-by-step explanation:
A grey whale is cruising at a depth of 233 feet below sea level. The depth below the sea level has the negative position, thus the initial position of the whale is -233.
It rises 73 feet, the position of the whale becomes 73 feet higher. This means we should add 73.
Then it comes up another 40 feet, so we need to add 40.
Mathematically,
The whale is at a depth 120 feet below the sea level.
340/100 = 3.4
255/3.4=75
The car on average used 75 liters for every 100km
m∠M=28°
Step-by-step explanation:
In the given figure we can see that the exterior angle at P is 48°.
From the axiom that when a line intersect other line, the angles formed have a sum of 180°
So the interior angle at P will be: 180°-48° = 132°
Now let
m∠P = 132°
m∠M = (3y+1)°
m∠N= (2y+2)°
As the sum of internal angles of triangle is 180°
So,
Subtracting 135 from both sides
Dividing both sides by 5
So,
m∠M = 3y+1 = 3(9)+1 = 27+1 = 28°
Hence,
m∠M=28°

Answer:
1. Lateral: 72 SA: 142
2. SA: 36 Lateral: 24
Step-by-step explanation:
1. perimeter of base times the height
2l+2w x h
2(5) + 2(7) x 7
24 x 3 = 72
Surface area: A=2(wl+hl+hw)=2·(7·5+3·5+3·7)=142
2. Surface Area
Using the formulas
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving forA
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=5·2+4·2+3·2+1
2·﹣54+2·(5·4)2+2·(5·3)2﹣44+2·(4·3)2﹣34
=36
Lateral: A=(a+b+c)h=(5+4+3)·2=24
