How many tiles of dimension 22.5 cm x 10 cm x 7.5 cm can be painted if the paint is sufficient for the surface area 2812.50 m2 (

fenix001 [56]

Answer:

30 000 tiles

Step-by-step explanation:

Firstly convert the dimensions into metres

Then find the total surface area for one tile...in its....;

T.Surface area = 2(0.225 × 0.1) + 2(0.1 × 0.075) + 2(0.225 × 0.075)

Total surface area of one tile = 0.09375m^2

Then divide it into the surface area that the paint can be applied to....

2812.50 ÷ 0.09375 = 30 000 tiles

Calculate simple interest earned on a deposit of $1000 at a rate of 3% for 10 years.

Degger [83]

$\bf ~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\\ P=\textit{original amount deposited}\dotfill & \$1000\\ r=rate\to 3\%\to \frac{3}{100}\dotfill &0.03\\ t=years\dotfill &10 \end{cases} \\\\\\ I=(1000)(0.03)(10)\implies I=300$

The motion of a ship riding at anchor can be modeled by y=25-4 cos (pi/6)t, where y is the water depth in feet and t is the time

balandron [24]

Answer: 29 feet (deepest) at 6 am

21 feet (shallowest) at Midnight & Noon

<u>Step-by-step explanation:</u>

y = -4 cos (π/6)t +25

Amplitude (A) = 4

-A means it is a reflection over the x-axis (starts at minimum)<em> </em>

Period = 2π/B → Period = 12

Phase shift = C/B → Phase Shift = 0

Midline (D) = 25

Midline (D) ± Amplitude (A) = Max & Min

Max: 25 + 4 = 29

Min: 25 - 4 = 21

Change the coordinates of y = cos (x) as follows:

x-value: Add C then divide by B
y-value: Multiply by A then add D

Note that the equation shows: A = -4, B = π/6, C = 0, D = 25

$\begin{array}{c|ccc|cl}\underline{\quad x\quad}&\underline{\quad y\quad}&&\underline{\quad (x+C)/B\quad}&\underline{\quad Ay+D\quad}\\0&1&&0&21&minimum\\\pi&0&&3&25&midline\\\pi &-1&&6&29&maximum\\3\pi/2&0&&9&25&midline\\2\pi&1&&12&21&minimum\\\end{array}$
