A navy cruiser detects a nuclear submarine that is 2500 feet from the cruiser. The angle between the water level and the submarine is 15.5 degrees. How deep is the submarine?
Answer:
Depth of the submarine = 668.09 feet
Step-by-step explanation:
From the figure attached,
In triangle ABC,
Distance between a navy cruiser and a nuclear submarine = 2500 feet
Angle between the water level and the submarine = 15.5°
By applying sine rule in the given triangle,
sin(∠BAC)° = [tex]\frac{BC}{AC}[/tex]
sin(15.5°) = [tex]\frac{BC}{2500}[/tex]
BC = 2500[sin(15.5)]
BC = 668.09 feet
Therefore, submarine is 668.09 feet deep in the sea.
three consecutive multiples of 2 is 36 then the multiples are
Answer:
9, 12, 15A multiple of 3 can be written 3n where n is a positive integer.
So 3 consecutive multiples of 3 can be written
3n,3n+3,3n+6
The sum of these is 36
3n+3n+3+3n+6=36
9n+9=36
Divide through by 9
n+1=4
n=3
If n=3 then 3n=9 and the three consecutive multiples of three are 9, 12 and 15 which do indeed total 36

Find value of x pleaseee
Answer:
Step-by-step explanation:
you can use the side angle side formula ( a form of Law of Cosines)
a^2 = b^2 + c^2 − 2bc cos(A)
where x = a , then
[tex]x^{2}[/tex] = [tex]5^{2}[/tex] +[tex]3^{2}[/tex] - 2*5*3*cos(107)
[tex]x^{2}[/tex] = 25 + 9 - 30 * (-0.292371)
[tex]x^{2}[/tex] = 25 + 9 -8.7711511
x = 5.0228 cm

Answer:
1600 cubic feet
Step-by-step explanation:
8 x 2 1/2 = 8 x 2.5 = 20
20 divided by 1/2 = 10
8 x 10 x 20 = 1600

Step-by-step explanation:
1- mass of earth is 1/95 of the mass of Saturn. if mass of earth is 5.97 x 10^24 kg.find mass of Saturn. show your all work out.
2- write 267000000 in standard form.
3- Maria, Carolina and Pedro receives $1600 from their grandfather in ratio 7:5:4. calculate share of each
Answer:
5.6715 * 10^26 kg
Step-by-step explanation:
Given that :
Mass of earth = 1/95 the mass of saturn
If Mass of earth = 5.97 x 10^24 kg
Let the mass of saturn = x
5.97 x 10^24 kg = 1/95 * x
5.97 x 10^24 kg = x / 95
x = 95 * 5.97 x 10^24 kg
x = 567.15 * 10^24
x = 5.6715 * 10^26 kg
Mass of saturn = 5.6715 * 10^26 kg
After driving for 2 hours, Juan is 110 miles from his home. After driving 5 hours, he is 275 miles from his home. What is his average rate of change?
Answer:
392
Step-by-step explanation:
The average rate of change will be "55 m/h".
According to the question,
→ After 2 hours (t₁),
Juan is 110 miles (d₁) from his home.
→ After 5 hours (t₂),
Juan is 275 miles (d₂) from his home.
→ The average rate of change will be:
= [tex]\frac{d_1+d_2}{t_1+t_2}[/tex]
By substituting the values, we get
= [tex]\frac{110+275}{2+5}[/tex]
= [tex]\frac{385}{7}[/tex]
= [tex]55 \ m/h[/tex]
Thus the above is the right solution.

Answer: 1. 34 degrees+34 degrees=68 180-68=112 so x=112 degrees
2. 84+22=106 180-106=74 so x=74 degrees
3. 126+20=146 180-146=34 so x=34 degrees
4. both angles on both sides are 40 so 40+40=80 180-80=100 so x=100 degrees

Answer: Weight of the remaining block of wood =400g
Step-by-step explanation:
Total Weight of five(5) blocks = 3kg = 3000g
Weight of 4 out of the 5 blocks = 650x 4= 2600g
Weight of the remaining block of wood =Total Weight of five(5) blocks-Weight of 4 out of the 5 blocks
= 3000g-2600g
=400g
