A submarine cuts through the water at an elevation of 203 meters under the sea. The sub rises, and the elevation changes by 4.3
maw [93]
The answer is -76.1 meters.

The submarine elevation before rising is -203 meters (it is negative because it is under the sea level which has 0 elevation): d₁ = -203 m
After the first rising, it moved 64.5 m: l₁ = 4.3 · 15 = 64.5 m
After the second rising, it moved 62.4 m: l₂ = 5.2 · 12 = 62.4 m

So, to calculate the elevation of the submarine after rising (d₂), we will add (because it is not going deeper, it rises toward the elevation of 0) two movements to the elevation before rising:
d₂ = d₁ - (l₁ + l₂) = -203 + (64.5 + 62.4) = -203 + 126.9 = -203 + 126.9 = -76.1.

tatyana61 [14]

Answer:

<u>12 years</u>

Step-by-step explanation:

Let Kishor's present age be denoted by x.

According to the question :

  • He will 3 times as old as he was 4 years ago after 12 years

Therefore, the equation is :

  • x + 12 = 3(x - 4)

Solving :

  • x + 12 = 3x - 12
  • 3x - x = 12 + 12
  • 2x = 24
  • x = <u>12 years</u>

<u></u>

Hence, Kishor's present age is <u>12 years</u>.

Please help me with this I need to find out what y is
julsineya [31]

Answer:

26°

Step-by-step explanation:

<DFG+<EFG = 180°( Being sum of adjacent angle in linear pair is 180°)

You can also write;

<DFG+<EFG = 180°( Being sum of supplementary angle is 180°)

By putting the value of those angles;

5y+3+(2y-5)=180

5y+3+2y-5=180

5y+2y-5+3 =180°

7y-2=180°

7y=180+2

7y=182

y=182/7

y=26°

Hence,

The value of y is 26°
