Answer:

31\ ft

Step-by-step explanation:

we know that

The scale is equal to

\frac{1}{10}\frac{cm}{ft}

so

by proportion

Find how far apart should the actual trees be planted, if the trees are 3.1\ cm apart in the plan

\frac{1}{10}\frac{cm}{ft}=\frac{3.1}{x}\frac{cm}{ft}\\ \\x=10*3.1\\ \\x=31\ ft

Phil had 93 dollars, and his sister owed 10 dollars to her friend. How much should Phil give to his sister for each of them to h
Olegator [25]

Answer:

Phil should have $41.5 and Phil should give $51.5 to her sister.

Step-by-step explanation:

Given that,

amount of money Phil have = $93

amount of money Phil's sister owed to her friend = 10

$10 of the $93 is going to his sister's friend; that leaves $83 for Phil and his sister.

If they are to finish with the same amount, then each should have half of the Phil's money after she paid $10

So,

83/2

= 41.5 each but since Phil's sister have to give 10 rupees in debt so

41.5+10

= 51.5

So Phil should have $41.5 and Phil should give $51.5 to her sister.

Sindrei [870]

We are given that the passenger's jet is flying at a speed of 185 miles per hour, with a direction of 36 degrees, and the wind speed being 47 mph with a direction of 120 degrees. From this, you could create a diagram is shown in the attachment.

[ 185 cos 36, 185 sin 36 ]

+ [ 47 cos 120, 47 sin 120 ]

_______________________

[ 185 cos 36 + 47 cos 120, 185 sin 36 + 47 sin 120 ]

√( 4263  + 33988 )^2

= ( About ) √38251 = 195.57 mph

<u><em>Solution = 195.6 mph, 069° </em></u>
