Answer:

A submarine hovers at 66 and 2/3 yards below sea level. If it ascends 24 and 1/8 yards and then descends again 78 and 3/4 yards, what is the submarine’s new position, in yards, below sea level?

Answer:

The submarine's new position is below sea level.

Solution:

Given that a submarine hovers at yards below sea level. This means that the position of submarine is negative

Therefore, we get

Also given that it ascend yards

So we have to add and

The submarine descends again 78 and 3/4 yards

This means we need to subtract

Therefore, the submarine's new position is below sea level.

Answer:

Answer:

The answer-121 and 7/24

Hope this helps

Find the measure of a central angle of a regular polygon with 10 sides

Answer:

114 degrees

Step-by-step explanation:

The formula to find the measure of all angles in a regular polygon is , where n = total number of sides.

Thus, we substitute n for 10, and you get:

If the shape is a regular polygon and it has ten sides, meaning all sides are equal, then all you do is divide 1440 by 10, to get the final answer of 114.

A central angle in a regular ten-sided polygon would be 144 degrees.

A coin is tossed twice. what is the probability of getting two consecutive tails

A single coin has Head, H or Tail, T.

If it is tossed twice, possible outcome: HH, or HT or TH or TT

Probability of a H = 1/2, For a T = 1/2

For two consecutive tails = TT

TT = T and T = (1/2) * (1/2) = 1/4

Two Consecutive Tails = 1/4

If it is tossed twice, possible outcome: HH, or HT or TH or TT

Probability of a H = 1/2, For a T = 1/2

For two consecutive tails = TT

TT = T and T = (1/2) * (1/2) = 1/4

Two Consecutive Tails = 1/4

What is the absolute value of -12 and the absolute value of 19

The absolute value of -12 is -12.

The absolute value of 19 is 19.

I have no idea if it is correct but, I hope this helps!!!

Answer:

Absolute value of -12 is 12 also written as |-12|=12 and the absolute value of 19 is 19 also written like |9|=9. An absolute value is never negative. It's always positive

Step-by-step explanation:

Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative. When we take the absolute value of a number, we always end up with a positive number (or zero). Whether the input was positive or negative (or zero), the output is always positive (or zero).

Hope this helps :)

Marty has a fenced yard in the shape of a rectangle. it's area is 635.4 square feet. The width of the yard is 18 feet. Whatis the length of the fence?

The fence is 1306.8 feet

because you add all sides 635.4+635.4+18+18

because you add all sides 635.4+635.4+18+18

The Lee’s have three children. The oldest is twice as old as the youngest. The middle child is five years older than the youngest. If the sum of the ages is 57, how old is each child?

The three children are x, 2x, and x+5

So set up an equation: x+2x+x+5=57

Solve: 4x=52 so x=13

So the ages are...

13, 18, 26

Check: 13+18+26=57
