Use formula p=m/v
P is density
M is mass
V volume
So you have the volume already now 8x5x4= 160 which is the volume
P= 1800/160 after you divide you get 11.25
The density is 11.25
Answer:
As per the statement
The altitude of the balloon is 50 feet and the rope is 75 feet long.
⇒ Altitude of the balloon = 50 feet.
And length of the rope = 75 feet.
We have to find the angle that rope makes with ground,
Using Sine ratio:

You can see the diagram as shown below.
Here,
Opposite side = Altitude of the balloon = 50 feet.
Hypotenuse side = length of the rope = 75 feet.
Substitute the given values we have;

⇒
= 41.8°
Therefore, the angle that the rope makes with the ground is, 41.8 degree
Answer:
-24
Step-by-step explanation:
you first do the parenthesis first then you do 3x4 12 then you add 9 and then -48 so your at negative 40 then you do 8+8 which is 16.
6.2% of 457.88....turn percent to decimal....." of " means multiply
0.062(457.88) = 28.39 will be deducted
