Answer:

The FitnessGram™ Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster each minute after you hear this signal. [beep] A single lap should be completed each time you hear this sound. [ding] Remember to run in a straight line, and run as long as possible. The second time you fail to complete a lap before the sound, your test is over.ep explanation:

Avery Tag makes an investment today (January 1, 2017). Avery will receive $40,000 every December 31st for the next six years (20
marshall27 [118]
Answer: $2,000,000

Explanation: Let X be the amount of Avery's investment. Since she will receive $40,000 every year for the next six years, the most she will earn is
$40,000 × 6 = $240,000.

Since she wants to earn 12% on her investment, her earnings is equal to 12% of X = 0.12X. Since the most she will earn is $240,000,

0.12X ≤ 240,000
X ≤ 240,000 ÷ 0.12 = 2,000,000 (Divide both sides by 0.12)

Hence X ≤ 2,000,000. Therefore, the most amount she should invest is $2,000,000.

A pyramid has a square base with sides of length s. The height of the pyramid is equal to - of the length of a side on the base.
Vera_Pavlovna [14]
<h3><u>Question:</u></h3>

A pyramid has a square base with sides of length s. The height of the pyramid is equal to 1/2 of the length of a side on the base. Which formula represents the volume of the pyramid?

<h3><u>Answer:</u></h3>

<em><u>The formula represents the volume of the pyramid is:</u></em>

V=\frac{1}{6}s^3

<h3><u>Solution:</u></h3>

<em><u>The volume of square pyramid is given by formula:</u></em>

V = \frac{1}{3} a^2h

Where, "h" is the height of pyramid

"a" is the length of side of base

Here given that, pyramid has a square base with sides of length s

Therefore,

a = s

The height of the pyramid is equal to 1/2 of the length of a side on the base

h = \frac{1}{2} \times s\\\\h = \frac{s}{2}

<em><u>Thus the volume of pyramid becomes:</u></em>

V = \frac{1}{3} \times s^2 \times \frac{s}{2}\\\\V = \frac{s^3}{6}

\boxed{V=\frac{1}{6}s^3}

Thus the  formula  represents the volume of the pyramid is \frac{s^3}{6}
