Elina [12.6K]2 years ago
7 0

Answer:

\circ\ \ 36\sqrt{3}

Step-by-step explanation:

CD=12\times \sin(60)  =12\times \frac{\sqrt{3} }{2}

<u><em>Important Note</em></u>:………………………………………………………………………………………

ABC is an equilateral triangle because it has 2 angles of measure 60

===========================================================

According to the note AB = 12

<u><em>Final answer</em></u> :

\text{Area of triangle ABC} =\frac{AB\times CD}{2}

                                  =\frac{12\times 6\sqrt{3} }{2}

                                  =\frac{72\sqrt{3} }{2}

                                  =36\sqrt{3}

Pamela drove her car 99 kilometers and used 9 liters of fuel. She wants to know how many kilometers, (k), she can drive with 12
solong [7]
99 km ... 9 liters
x km   ... 12 liters

If the relationship is proportional, we have

\frac{99}{x} = \frac{9}{12}

from where 

x =  \frac{99*12}{9}= \frac{1188}{9}=\bold{132}

The answer is 132 kilometers.

Wewaii [24]

Answer:

40/3

Step-by-step explanation:

w = weight of soil needed

f = number of flower beds

a = constant value

w = a * f

<em>substitute</em>

10 = 6a

<em>simplify</em>

5/3 = a

w = (5/3)f

<em>plug in 8</em>

w = (5/3)(8)

<em>simplify</em>

w = 40/3

son4ous [18]

Answer:

The average speed of the entire trip is 8.5 miles per hour.

Step-by-step explanation:

Speed = Total  Distance / Total Time

So we have to find the total distance and the total time taken .

1) From Gujranwala to Daska

speed= 25miles/hour           distance = 15miles

Time taken = distance / speed

                   = 15/25= 0.6 hours

2)  From Daska to Sialkot

speed= 40miles/hour           distance = 15miles

Time taken = distance / speed

                   = 40/15= 2.67 hours

3 ) From  Sialkot to Daska

speed= 30miles/hour           distance = 15miles

Time taken = distance / speed

                   = 30/15= 2 hours

The total distance traveled to three places is = 15+ 15+15= 45miles

The Total time taken is = 0.6+ 2.67+ 2= 5.267=5.3 hours

Speed = Total  Distance / Total Time

Speed= 45/ 5.3

          = 8.49=8.5 miles per hour

The average speed of the entire trip is 8.5 miles per hour.
