The correct answer to this question is 4.

In order to solve this problem, first make an image on your mind how the image is dilated.

The coordinate points at first is (1.5, 2.0). 
After dilation from the origin, the points became (6.0, 8.0)

Looking at it in fraction form, (new / old) we have
6.0 / 1.5 = 4.0
8.0 / 2.0 = 4.0

The quotient of each fraction yields to 4.0. This means that a = 4.

35 year old female. 5’8', 220 pounds. Calculate Adjusted Body Weight. (Round to the nearest tenth if applicable): ________
MakcuM [25]

Answer:

Her adjusted body weight is 78.26kg = 78.3kg, rounded to the nearest tenth.

Step-by-step explanation:

To find the Adjusted Body Weight(AjBW), first we have to consider the Ideal Body Weight(IBW).

We have the following formulas:

IBW = 45.5kg + 2.3kg*i, in which i is the number of inches that the woman has above 5 feet.

AjBW = IBW + 0.4*(ABW - IBW), in which ABW is her Actual Body Weight

So, in this problem:

Each pound has 0.45kg. So her weight is ABW = 220*0.45 = 99.8kg.

The woman is 8 inches above 5 feet, so i = 8.

IBW = 45.5 + 2.3*8

IBW = 63.9kg

Her ideal body weight is 63.9kg. Her adjusted body weight is:

AjBW = IBW + 0.4*(ABW - IBW)

AjBW = 63.9 + 0.4*(99.8-63.9)

AjBw = 78.26kg

Her adjusted body weight is 78.26kg = 78.3kg.

Whitley has run 16 miles. His slowest running time for a mile was 9 minutes and 14 seconds. His fastest running time for a mile
wolverine [178]

Answer:

275 minutes 12 seconds

Step-by-step explanation:

Given that :

slowest running time per mile = 9 minutes and 14 seconds

fastest running time per mile = 7

minutes and 58 seconds.

To estimate the time taken to run 16 miles ;

Obtain the Average of the two run times :

(9 minute 14 seconds) + (7 minutes 58 seconds) = 17 minutes 12 second

Hence it takes an average of 17 minutes 12 seconds per mile

Time taken to run 16 miles :

((17 * 60) + 12) * 16 = 16512 seconds

16512 / 60 = 275 minutes 12 seconds
