An assembly line inspector inspected 340 machine parts. 323 of the parts passed inspection. What percent of the machine parts di

tester [92]

Answer:

5% did not pass inspection

Step-by-step explanation:

Given

$Inspected= 340$

$Passed = 323$

Required

Determine the percentage of parts that didn't pass inspection.

First, we need to calculate the number of those that didn't pass inspection.

$Failed = Inspected - Passed$

$Failed = 340 - 323$

$Failed = 17$

Next, we calculate the percentage as follows:

$\% = \frac{Failed}{Inspected} * 100\%$

The above formula is derived by dividing the number of parts that didn't pass inspection by the total machine inspected, then multiplied by 100%

So:

$\% = \frac{17}{340} * 100\%$

$\% = \frac{17 * 100\%}{340}$

$\% = \frac{1700\%}{340}$

$\% = 5\%$

<em>5% did not pass inspection</em>

What is the area of a sector with a central angle of 8 π/11 radians and a radius of 7.2 ft? use 3.14 for π and round your final

coldgirl [10]

Answer:

$59.19 ft^2$

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

$r=7.2\ ft$

$\pi =3.14$

substitute

$A=(3.14)(7.2)^{2}$

$A=162.78\ ft^2$

step 2

we know that

The area of a circle subtends a central angle of 2π radians

using proportion

Find out the area of a sector with a central angle of 8 π/11 radians

$\frac{162.78}{2\pi }\frac{ft^2}{rad} =\frac{x}{(8\pi/11)}\frac{ft^2}{rad} \\\\x=162.78(8/11)/2\\\\x=59.19\ ft^2$

Please help with this problem <br> thanks so much

Lunna [17]

Answer:

5/17

Step-by-step explanation:

If we do the multiplication first, we get:

$\frac{4-(12\div-12)}{13+(-8\div-2)}$

If we do the division next, we get:

$\frac{4+1}{13+4} = 5/17$
