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:
210
Step-by-step explanation:
Multiply by the total amount by the decimal equivalent of 70% (0.7) to get your answer.
8-5=3
19-11=8
3/8=0.375
Rate of Change: 0.375
548800.
Use the fundamental counting principle and combinations formula to find the total possibilities. use combinations to find the combos then multiply each set of possibilities together.
7 nCr 3 = 35 hamburgers combo possibilities.
5 nCr 2 = 10 sides combo possibilities
8 nCr 3 = 56 drinks combo possibilities
8 nCr 2 = 28 ice cream combo possibilities
Multiply each possibility together to get total possibilities.
35*10*56*28 = 548800
R=train speed
p=plaane speed
t=time
d=st
100=tr
350=pt
p=4r-20
ok so 100 times 3.5=350
times 1st equaton by 3.5
350=3.5tr
350=pt
sub
3.5tr=pt
divide both sides by t
3.5r=p
sub p=4r-20
3.5r=4r-20
minus 3.4 from both sides
0=0.5r-20
add 20
20=0.5r
times 2
40=r
sub
p=4r-20
p=4(40)-20
p=160-20
p=140
plane=140kmph
train=40kmph
