A bike wheel is shown. Chords I J and L K intersect at point M. The length of I M is 16 centimeters, the length of M J is 7 cent

levacccp [35]

Answer:

The diameter of the wheel is 32 centimeters

Step-by-step explanation:

we know that

The <u><em>intersecting chords theorem</em></u> states that the products of the lengths of the line segments on each chord are equal.

so

In this problem

$(LM)(MK)=(IM)(MJ)$

substitute the given values

$(4)(x)=(16)(7)$

solve for x

$x=16(7)/4\\x=28\ cm$

Remember that

LK goes through the center of the wheel

That means----> LK is a diameter

$LK=4+x\\LK=4+28=32\ cm$

therefore

The diameter of the wheel is 32 centimeters

A company reports cost of goods manufactured of $918,700 and cost of goods sold of $955,448. Compute the average manufacturing c

kirill115 [55]

If the cost of goods manufactured of $918,700 and cost of goods sold is $955,448. The average manufacturing cost per unit assuming 18,374 units were produced is $102 per unit.

<h3>Average manufacturing cost per unit</h3>

Using this formula to determine the average manufacturing cost per unit

Average manufacturing cost per unit= Total cost/Number of units produced

Where:

Total cost=$918,700+$955,448=$1,874,148

Number of units produced=18,374 units

Let plug in the formula

Average manufacturing cost per unit=$918,700+$955,448/18,374

Average manufacturing cost per unit=$1,874,148/18,374

Average manufacturing cost per unit=$102 per unit

Therefore the average manufacturing cost per unit assuming 18,374 units were produced is $102 per unit.

85.87 J or heat energy is added to a 34.8 g mass of substance the temperature rises from 21.76°C

Andru [333]

Answer:

The required specific heat is 196.94 joule per kg per °C

Step-by-step explanation:

Given as :

The heat generated = Q = 85.87 J

Mass of substance (m)= 34.8 gram = 0.0348 kg

Change in temperature = T2 - T1 = 34.29°C - 21.76°C = 12.53°C

Let the specific heat = S

Now we know that

Heat = Mass × specific heat × change in temperature

Or, Q = msΔt

Or, 85.87 = (0.0348 kg ) × S × 12.53°C

Or , 85.87 = 0.4360 × S

Or, S = $\frac{85.87}{0.4360}$

∴ S = 196.94 joule per kg per °C

Hence the required specific heat is 196.94 joule per kg per °C Answer
