Hello!

To solve an algebraic equation, you must isolate the variable on one side. We’ll begin by restating the given equation:

12 + 12n = -48

Now subtract 12 from both sides of the equation:

12n = -60

Divide both sides by 12:

n = -5

We have now proven that “n” is equal to (-5).

I hope this helps!

Forensic specialists can estimate the height of a deceased person from the lengths of the person's bones. These lengths are subs

Lera25 [3.4K]

Answer:

$130.2845\leq h\leq 137.7245$

Step-by-step explanation:

Given an inequality that relates the height h, in centimeters, of an adult female and the length f, in centimeters, of her femur by the equation

$|h - (2.47f + 54.10)| \leq 3.72$

If an adult female measures her femur as 32.25 centimeters, we can determine the possible range of her height by plugging f = 32.25cm into the modelled equation as shown:

$|h - (2.47(32.25) + 54.10)| \leq 3.72\\|h - (79.9045 + 54.10)| \leq 3.72\\|h - (134.0045)| \leq 3.72\\$

If the modulus function is positive then:

$h - 134.0045 \leq 3.72\\h \leq 3.71+134.0045\\h\leq 137.7245$

If the modulus function is negative then:

$-(h - 134.0045) \leq 3.72\\-h+134.0045 \leq 3.72\\-h\leq 3.72-134.0045\\-h\leq -130.2845\\$

multiply through by -1

$-(-h)\geq -(-130.2845)\\h\geq 130.2845\\130.2845\leq h$

combining the resulting inequalities, the estimate of the possible range of heights will be $130.2845\leq h\leq 137.7245$

A cylindrical water tower has a height of 6 ft and a radius of 4 ft. How much water does the tower contain when it is 1/3 full?

viktelen [127]

V = pi r^2 h
But it says 1/3 full so
1/3 pi r^2 h
1/3 * 3.14 * 4^2 * 6
100.48ft cubed
Whichrounds off to 100.5

In the diagram below line l is parallel to line m which angles are congruent to angle 1

Alchen [17]

ANSWER

$\angle1 \cong \angle3$

$\angle1 \cong \angle8$

$\angle1 \cong \angle6$

EXPLANATION

Since line l is parallel to line m,

$\angle1 \cong \angle3$

because the two angles are vertically opposite angles.

$\angle1 \cong \angle8$

because the two angles are corresponding angles.

$\angle1 \cong \angle6$

because the two angles are alternate exterior angles.
