TTriangle H L I is shown. Line segment J K is drawn near point L to create triangle J L K. If △HLI ~ △JLK by the SSS similarity
pishuonlain [190]

Question:

\triangleHLI is shown. Line segment JK is drawn near point L to create \triangleJLK. If \triangleHLI ~ \triangleJLK by the SSS similarity theorem, then \frac{HL}{JL} =\frac{IL}{KL} is also equal to which ratio?

\frac{H I}{J K}      \frac{H J}{J L}     \frac{I K}{K L}     \frac{J K}{H I}      

Answer:

\frac{H I}{J K}

Step-by-step explanation:

Given

HLI ~ \triangleJLK

\frac{HL}{JL} =\frac{IL}{KL}

Required

Which other ratio equals \frac{HL}{JL} =\frac{IL}{KL}

\triangleHLI ~ \triangleJLK  implies that:

HL, IL and HI corresponds to JL, KL and JK respectively.

So, the possible ratios are:

HL : IL : HI = JL : KL : JK

Convert to fractions

\frac{HL}{JL} = \frac{IL}{KL} = \frac{HI}{JK}

So, from the list of options

\frac{H I}{J K} is equivalent to \frac{HL}{JL} =\frac{IL}{KL}

At a firm, ten entry-level employees earn $40,000 a year, 6 junior-level employees earn $60,000 a year, and 3 managers earn $80,
Mumz [18]

Answer: answer is: 1000000/19

Step-by-step explanation:

10/19 - 40k -> 10/19*40k= 400000/19

6/19- 60k -> 6/19*60k= 360000/19

3/19 - 80k -> 3/19*80k=240000/19

400000/19+360000/19+240000/19=1000000/19

answer is: 1000000/19
