a submarine travels at an elevation of -75 3/4 ft relative to sea level then its elevation changes by - 16 3/8 what is the new e

slamgirl [31]

Answer:

$New = -92\frac{1}{8}$

Step-by-step explanation:

Given:

$x = -75\frac{3}{4}$ --- Position

$\triangle x = -16\frac{3}{8}$ --- Change

Required

Find the new position

The new position is calculated as:

$New = x + \triangle x$

$New = -75\frac{3}{4} - 16\frac{3}{8}$

$New = -75.75 - 16.375$

$New = -92.125$

$New = -92\frac{125}{1000}$

$New = -92\frac{1}{8}$

Lucas' mom is eight years older than twice his age. The sum of their ages is 77. How old are Lucas and his mom?

Rudiy27

Answer:

Age of Lucas = 23 years

Age of Lucas Mom = 54 Years

Step-by-step explanation:

In this question we have to find the age of Lucas and his Mom

Let the age of Lucas be x

According to given condition

Twice of his age 2 * x =2x

Eight years older means age + 8x

Age of his mom = Twice of his age + 8

= 2x + 8 .................(ii)

now according to second condition

Age of Lucas + Age of his mom = 77

Put the values in the condition above

x + (2x + 8) = 77

x + 2x + 8 =77

3x + 8 = 77

subtracting 8 from both sides

3x + 8 - 8 = 77 -8

3x = 69

Dividing both sides by 3

x = 69 / 3

x = 23 years

Age of Lucas = 23 years

Now from equation (i)

Age of Lucas Mom = 2(x) + 8

putting in the value we get

Age of Lucas Mom = 2 ( 23) + 8

=46 + 8

=54 Years

Age of Lucas Mom = 54 Years

How can I tell if something is linear or nonlinear?

Anni [7]

Answer:

When something is linear it will meet the criteria, on a graph it will be a straight line, it won't have any curves in it.

When something is nonlinear it doesn't fit the criteria, on a graph it will be curved, never straight

Hope this helps ;)
