Answer:

B. 6

Detailed explanation:

<em>Alright, so using the Pythagorean theorem, </em>c^{2} =a^{2} +b^{2}<em> in this case, we have the "c" and "b" of the triangle. Therefor, we are looking for "a"</em>

<em>so, to solve the problem, simply begin by substituting what you already have:</em>

10^{2} =a^{2} +8^{2}

<em>Now that this is substituted, The next step is to go ahead and find the values after solving the exponents:</em>

10^{2} =100\\&#10;8^{2}=64

<em>Now, we need to find the value of "a".</em>

<em>In this case, we are provided with 4 options and one of them has to be correct.</em>

<u><em>If "a"=12 then "a squared" would equal 144.</em></u>

<u><em>the statement 100=144+64 is </em></u><u><em>incorrect.</em></u>

<u><em>If "a"=6 then "a squared" would be 36.</em></u>

<em>The statement 100=36+64 is </em><em>correct.</em>

<em>
</em><u><em>If  "a"=36 the "a squared" would be 1296.</em></u>

<u><em>The statement 100=1296+64 is </em></u><u><em>incorrect.</em></u>

<u><em>If "a"=18, then "a squared" would be 324.</em></u>

<u><em>The statement 100=324+64 is</em></u><u><em> incorrect.</em></u>

<u><em>Therefor, the answer is B.6</em></u>

<u><em></em></u>

Hope this helps ^-^

A company manufactures its product at a cost of $0.50 per item and sells it for $0.85 per item daily overhead is $600 how many i
Nataly_w [17]

so the company has an overhead of $600, usually that involves premises leasing and industrial equipment for the manufacturing of the product, that's cost.  The cost to make each item is 50 cents, so if the company produces "x" items, their cost is 0.5x total.

so our cost equation C(x) = 0.5x + 600   <---- items' cost plus overhead.

the company sells the product for 85 cents, so if they sell "x" items, their total revenue or income will be 0.85x.

so our revenue equation is simply R(x) = 0.85x.

as you already know, the break-even point is when.... well, you break even, no losses but no gains either, how much you take in is the same amount that you shelled out, namely R(x) = C(x).

\bf \stackrel{R(x)}{0.85x}=\stackrel{C(x)}{0.5x+600}\implies 0.35x=600\implies x=\cfrac{600}{0.35} \\\\\\ x\approx 1714.285714285714\implies \stackrel{\textit{rounded up}}{x=1714}

Jake built a skateboard ramp, if the distance of the ramp is 10 ft. The ramp rises a
ikadub [295]

Answer:

Angle made by ramp with ground is ≈19.29^{\circ}

Step-by-step explanation:

Diagram of given scenario is shown below.

Given that,

Horizontal Distance of Skateboard ramp is 10 ft.

Height of Skateboard ramp is 3.5 ft.

From figure,

It is forming a Right angle triangle \triangle ABC.

In \triangle ABC, AB=3.5 and BC=10.

Clearly see that we need to find measure of angle \angle C.

Using Trigonometric ratio:

     Tan(\theta)= \frac{Perpendicular}{Base}

So,  Tan(\angle C) = \frac{AB}{BC} =\frac{3.5}{10} =0.35

Then \angle C=Tan^{-1} (3.5)=19.290046^{\circ}

Therefore, Angle made by ramp with ground is ≈19.29^{\circ}

Kim has 8 dollars less than twice Ricky. If
olya-2409 [2.1K]

Based on the information given, it should be noted that the correct option is C. 3x - 8.

<h3>Solving equations.</h3>

From the information given, it was stated that Kim has 8 dollars less than twice Ricky. This will be:

= (2 × x) - 8.

= 2x - 8

Also, Ricky has x dollars. Therefore, the amount that they have together will be:

= 2x - 8 + x

= 3x - 8
