Half half for both (since all three are fair coins).

If you actually write it out, the choices are: HHH, HHT, HTT, HTH, TTT, TTH, THT, THH.

An engineer is designing a fountain that shoots out drops of water. The nozzle from which the water is launched is 3 meters abov

Hoochie [10]

Answer:

After 3 seconds

Step-by-step explanation:

Given

$h(t) = -5t^2 + 14t + 3$

Required

Time the drop will hit the ground

When the drop hits the ground,

$h(t) = 0$

So, we have:

$0 = -5t^2 + 14t + 3$

Rewrite as:

$5t^2 - 14t - 3 = 0$

Expand

$5t^2 + t - 15t - 3 = 0$

Factorize

$t(5t + 1) -3(5t + 1) = 0$

Factor out 5t + 1

$(t -3)(5t + 1) = 0$

Split

$t -3 = 0$ or $5t + 1 = 0$

Solve for t

$t = 3$ or $5t = -1$

Time cannot be negative.

So:

$t = 3$

A cylinder has a radius of 8 meters and a height of 4 meters. .

Novay_Z [31]

<h2><u>Solution</u> :-</h2>

Given : Radius of cylinder = 8 m

Height = 4 m

Volume of cylinder = πr²h cu. units

= 22/7 × 8 × 8 × 4 m³

= 804.57 m³ (approx.)

Curved surface area = 2πrh sq. units

= 2 × 22/7 × 8 × 4 m²

= 201.14 m² (approx.)

Total surface area = 2πr(r + h) sq. units

= 2 × 22/7 × 8 (8 + 4) m²

= 2 × 22/7 × 8 × 12 m²

= 603.43 (approx.)

A clerk is marking up merchandise 34%. The original price of an item is $455. What will be the retail price?

Galina-37 [17]

Take the orginal price and multiply it by 1.34.
455 * 1.34 = $609.70 in retail.

The longer way would be to take 34% of 455 and then add it to 455.
