The amount of gas that a helicopter uses is directly proportional to the number of hours spent flying. The helicopter flies for
dezoksy [38]

Answer: 44 gallons

Step-by-step explanation:

Using proportion,

33 gallons = 3hours

X = 4hours

Cross multiply

3 × X = 33 × 4

3X = 132

Divide bothside by 3

3x/3 =132/3

X = 44

Therefore the helicopter uses 44gallons for 4 hours.

Triangle ABC has A(-3,6),B(2,1), and C(9,5) what the length of side AB? What the length BC what the length AC and what ABC
vovikov84 [41]

Answer:

<em>AB = 5√2</em>

<em>AC = √145</em>

<em>BC = √65</em>

Step-by-step explanation:

Using the formula for calculating the distance between two points

D = √(x2-x1)²+(y2-y1)²

For AB A(-3,6),B(2,1),

AB = √(2+3)²+(1-6)²

AB = √(5)²+(-5)²

AB = √25+25

AB =  √50

<em>AB = 5√2</em>

For AC A(-3,6) and C(9,5)

AC = √(9+3)²+(5-6)²

AC = √(12)²+(-1)²

AC = √144+1

<em>AC = √145</em>

For BC B(2,1), and C(9,5)

BC = √(9-2)²+(5-1)²

BC = √(7)²+(4)²

BC = √49+16

<em>BC = √65</em>

<em></em>

<em>Since All the sides are difference, hence triangle ABC is a scalene triangle</em>
