Answer:

27.2mm²

Step-by-step explanation:

Area of a triangle = $\frac{1}{2}$ * base * height

Base of this triangle = 8mm

Height = 6.8mm

Area = $\frac{1}{2} * 8mm * 6.8mm$

= 4mm * 6.8mm

= 27.2mm²

If a wheel with a radius of 80 inches spins at a rate of 50 revolutions per minute, find the approximate linear velocity in mile

Lubov Fominskaja [6]

$\bf \textit{arc's length}\\\\
s=rw\qquad 
\begin{cases}
r=radius\\
w=\textit{angular speed}
\end{cases}\qquad w=\cfrac{50 rev}{min}\cdot \cfrac{2\pi }{rev}
\\\\\\
w=\cfrac{100\pi }{min}\qquad s=80in\cdot \cfrac{100\pi }{min}\implies s=\cfrac{8000\pi\ in}{min}\\\\
-------------------------------\\\\
\textit{now to convert it to miles/hr}
\\\\\\
\cfrac{8000\pi\ in}{min}\cdot \cfrac{ft}{12in}\cdot \cfrac{mile}{5280ft}\cdot \cfrac{60min}{hr}\implies \cfrac{8000\pi \cdot 60\ in}{12\cdot 5280\ hr}$

Convert 185 degrees Celsius to degrees Fahrenheit. Round your answer to the nearest degree

lakkis [162]

Hello! :3

Answer:

The Correct Answer is 365 °F

Step-by-step explanation:

The C to F formula is $(C ~x~ 9/5) + 32 = F$

When we do 185 for C in the formula, we get $(185 ~x~ 9/5) + 32 = F.$

To solve, $(185 ~x~ 9/5) + 32 = F.$ we first multiply 9 by 185, then we divide the product by 5, and then finally we add 32 to the quotient to get the answer.

$185~x~9=1665$

$1665 /5=333$

$333+32=355$

Therefore, the answer to 185 C to F is 365 which can be written like this

⇒ 185 °C = 365 °F

hope this helps you!

The map shows the location of the airport and a warehouse in a city. Though not displayed on the map, there is also a factory 72

lisov135 [29]

$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\\sqrt{(-27-27)^2+(36+36)^2}\\\\ \sqrt{54^2+72^2} \\\\ \sqrt{8100} \\\\90\\\\\\90+54 =\boxed { 144}\\\\\sf The~ distance~ 90~ is~ from ~the~ warehouse~ to ~the ~airport\\\\The~ distance~ 54~ is~ from ~the~ airport~ to ~the~ factory\\\\So,~ the~ total~ distance~ is~ 144$
