Uca is designing a propeller system that consists of 3 blades, each of which is

zmey [24]

Answer:

The weight of the three blades together is $134\ g$

Step-by-step explanation:

step 1

Find the area of the circle

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=4\ in$

assume

$\pi=3.14$

substitute

$A=(3.14)(4)^{2}$

$A=50.24\ in^{2}$

step 2

Find the area of the 3 blades

we know that

The area of the 3 blades represent a central angle of 60 degrees, so

its a 1/6 of the area of complete circle

$A=50.24/6=8.37\ in^{2}$

step 3

Find the weight of the three blades together to the nearest gram

$(8.37\ in^{2})*(16\ g/in^{2})=134\ g$

Solve the following:<br> a) 4x 3= 2x + 7<br><br> b) 2x+6= 7x14

nikdorinn [45]

<h2><u>Correct question</u> : 4x - 3 = 2x + 7 </h2>

<h2><u>Solution</u> : 4x - 3 = 2x + 7 </h2>

$4x - 2x = 7 + 3 \\ \\ 2x = 10 \\ \\ x = \frac{10}{2} \\ \\ x = 5.$

<h2><u>Correct Question</u> : 2x + 6 = 7x - 14</h2>

<h2><u>Solution</u> : 2x + 6 = 7x - 14</h2>

$2x - 7x = - 14 - 6 \\ \\ - 5x = - 20 \\ \\ x = \frac{20}{5} \\ \\ x = 4.$
