Answer:

b =\frac{A}{h}

Step-by-step explanation:

Given that:

A = bh           .....[1]

Solve for b:

Division property of equality states that you divide the same number to both sides of an equation.

Divide equation [1] both sides by h;

\frac{A}{h} = \frac{bh}{h}

Simplify:

\frac{A}{h} = b

or

b =\frac{A}{h}

Therefore, the value of b is:

b =\frac{A}{h}

What is equavilent to (10x+7r-r^(2))+(-6r^(2)-18+5r)
mote1985 [20]

Answer:

−7r^(2)+12r+10x−18

Step-by-step explanation:

Grab the original equation: 10x+7r−r^(2)−6r^(2)−18+5r

For subtraction bits, treat them as negatives: 10x+7r+−r^(2)+−6r^(2)+−18+5r

Combine like terms: (−r^2+−6r^2)+(7r+5r)+(10x)+(−18)

Simplify that, and you get your final answer: −7r^(2)+12r+10x+−18

How does graphing linear inequalities differ from graphing linear equations?​
Ivan

Explanation:

When the inequality symbol is replaced by an equal sign, the resulting linear equation is the boundary of the solution space of the inequality. Whether that boundary is included in the solution region or not depends on the inequality symbol.

The boundary line is included if the symbol includes the "or equal to" condition (≤ or ≥). An included boundary line is graphed as a solid line.

When the inequality symbol does not include the "or equal to" condition (< or >), the boundary line is not included in the solution space, and it is graphed as a dashed line.

Once the boundary line is graphed, the half-plane that makes up the solution space is shaded. The shaded half-plane will be to the right or above the boundary line if the inequality can be structured to be of one of these forms:

  • x > ...   or   x ≥ ...   ⇒ shading is to the right of the boundary
  • y > ...   or   y ≥ ...   ⇒ shading is above the boundary

Otherwise, the shaded solution space will be below or to the left of the boundary line.

_____

Just as a system of linear equations may have no solution, so that may be the case for inequalities. If the boundary lines are parallel and the solution spaces do not overlap, then there is no solution.

_____

The attached graph shows an example of graphed inequalities. The solutions for this system are in the doubly-shaded area to the left of the point where the lines intersect. We have purposely shown both kinds of inequalities (one "or equal to" and one not) with shading both above and below the boundary lines.

What do you add to 19/4 to make 5
raketka [301]
You add 1. 19 divided by 4... it’s not a full number. (Whole number). But, 19 plus 1 equals 20. 20 divided by 4 is 5

A 20-ft-long wire is used to support a television antaans. The wire is connected to the
MariettaO [177]

Answer:

The distance of base of wire to the base of tower is 13.27 ft

Step-by-step explanation:

Given as :

The measure of wire connected between base ad antenna top = 20 ft

The wire is connected to the  antenna on tower at height h = 15 ft above the ground

Let The distance of base of wire to the base of tower = x ft

Let the angle drawn on ground = Ф

Now, According to question

<u>In figure AOB</u>

Sin angle = \dfrac{\textrm perpendicular}{\textrm hypotenuse}

i.e SinФ = \dfrac{\textrm AB}{\textrm BO}

Or,  SinФ = \dfrac{\textrm h}{\textrm 20}

Or,  SinФ = \dfrac{\textrm 15}{\textrm 20}

Or, SinФ = \dfrac{\textrm 3}{\textrm 4}

or, Ф = sin^{-1}(\frac{3}{4})

∴ Ф = 48.5°

<u>Now, Again from figure</u>

Tan angle = \dfrac{\textrm perpendicular}{\textrm base}

i.e TanФ = \dfrac{\textrm AB}{\textrm OA}

Or, Tan 48.5° = \dfrac{\textrm h}{\textrm x}

Or, 1.13 = \dfrac{\textrm 15}{\textrm x}

∴ x = \dfrac{\textrm 15}{\textrm 1.13}

i.e x = 13.27 feet

So, The distance of base of wire to the base of tower = x = 13.27 ft

Hence, The distance of base of wire to the base of tower is 13.27 ft Answer
