Vladimir [108]

Answer:

I think the closest would be 41.5%

Step-by-step explanation:

If you take the number of passengers left on the plane and divide by the total number of passengers that were on the plane in the beginning, you would get 58.5%. That's the % of how many people are left on the plane. So, you would then do 100%-58.5% to get the answer 41.5%. Hope this helps! :)

GrogVix [38]

Answer:

V = 120 cm^3

Step-by-step explanation:

The volume is

V = BH where B is the base and h is the height

The base is the triangle

B = 1/2 (bh)

B = 1/2 6*4

B = 12

V = 12* 10

V = 120 cm^3

A hot air balloon is floating above a straight road. To estimate their height above the ground, the balloonists simultaneously m
san4es73 [151]

Answer:

h=1.99 miles

Step-by-step explanation:

Let's call h the balloon's height above the ground and b the horizontal distance between the balloon and the first milepost.

If the angle of the depression of this milepost is 24 degrees, we can say the following:

tan(24)=\frac{h}{b}

<em>b=\frac{h}{tan(24)}(equation 1)</em>

For the next milepost, the horizontal distance between the balloon and tihs milepost will be (b+1)miles and the angle of depression will be 20 degrees, so we can say the following

tan(20)=\frac{h}{b+1}

b+1=\frac{h}{tan(20)}

b=\frac{h}{tan20}-1

then, replacing from <em>equation 1</em>

\frac{h}{tan(24)} =\frac{h}{tan(20)}-1

1 =\frac{h}{tan(20)}-\frac{h}{tan(24)}

1 =h*(\frac{1}{tan(20)}-\frac{1}{tan(24)})

h=\frac{1}{(\frac{1}{tan(20)}-\frac{1}{tan(24)})}

Resolving, we'll find the value of h

h=1.99 miles

So, the balloon's height above the ground is 1.99miles
