Step-by-step explanation:
A ship is stationary at sea. A tugboat is 28 km away at a bearing of 315°, and a yacht is 21 km from the tugboat at a bearing of 210°. Draw a scale diagram showing the positions of the three vessels. Use a scale of 1 : 350,000. Measure the distance from the ship to the yacht to the nearest km.
The distance of the yacht from the ship is found by accurately drawing
the relative location of the three vessels.
Response:
The measured distance of the yacht from the ship is approximately 30 km.Which drawing method can be used in which the distance of the yacht from the ship can be measured?The given parameters are;
Distance of the tugboat from the ship, a = 28 km
Bearing of tugboat from the ship = 315°
Distance of the yacht from the tugboat, b = 21 km
Bearing of the yacht from the = 210°
Using a scale of 1 : 350,000, we have;
[tex]The \ drawing \ of \ a = \mathbf{\dfrac{28,000}{350,000} }= 0.08[/tex]
The length of a in the drawing = 0.08 m = 8 cm
[tex]The \ drawing \ of \ b = \mathbf{\dfrac{21,000}{350,000}} = 0.06[/tex]
Which gives;
b in the drawing = 0.06 m = 6 cm
Using the above dimensions and directions, the drawing of the relative
location of the three vessels can be accurately created using MS Word.
From the application, the vector form of the distance, d, of the ship from the yacht is presented as follows;
d = 8.655·i + 0.445·jWhich gives;
d = √(8.655² + 0.445²) = 8.67
Which gives;
Distance of the yacht from the ship on the drawing is d ≈ 8.67 cm = 0.0867 mActual distance = 0.0867 m × 350,000 = 30,345 m = 30.345 km ≈ 30 km
The distance of the yacht from the ship ≈ 30 kmUsing cosine rule, where the angle formed at the tugboat = 75°, we have;
d² = 28² + 21² - 2 × 28 × 21 × cos(75°) ≈ 920.63
Which gives;
d ≈ √(920.63) ≈ 30
The distance of the yacht from the ship, d ≈ 30 km

Answer:
area: 60π cm² ≈ 188.5 cm²volume: 63π cm³ ≈ 197.9 cm³doubling the radiusStep-by-step explanation:
(a)The surface area of a right cylinder is given by the formula ...
SA = 2πr(r +h) . . . . . radius r, height h
Filling in the given values, we find the area to be ...
SA = 2π(3 cm)(3 +7 cm) = 60π cm² ≈ 188.5 cm²
__
(b)The volume of the cylinder is given by the formula ...
V = πr²h . . . . . radius r, height h
Filling in the given values, we find the volume to be ...
V = π(3 cm)²(7 cm) = 63π cm³ ≈ 197.9 cm³
__
(c)The volume is proportional to r², so doubling the radius will multiply the volume by 2² = 4.
The volume is proportional to the height, so multiplying the height by 3 will multiply the volume by 3.
4 > 3, so doubling the radius gives the most volume

Find the probability of having 2, 3, or 4
successes in five trials of a binomial
experiment in which the probability of
success is 40%.
p = [?] %
Round to the nearest tenth of a percent.
Answer:
16% for 2 successes, 6.4% for 3 successes, 2.6% for 4 successes, and 1% for 5 successes
Step-by-step explanation:
Since the success rate of a binomial experiment is 40%, converted to 0.4, you get the equation of f(x) = (0.4)^x, for where x is the amount of successful experiments
For the success of 2 experiments:
f(2) = (0.4)^2
=0.16 => 16%
For the success of 3 experiments:
f(3) = (0.4)^3
= 0.064 => 6.4%
For the success of 4 experiments:
f(4) = (0.4)^4
= 0.0256 => 2.56% => ~2.6
For the success of 5 experiments:
f(5) = (0.4)^5
= 0.01024 => 1.024% => ~1%

determine all combinations of lengths that could be used to make a traingle 1,3,6,8
Answer:
3, 6, and 8 for a triangle
Step-by-step explanation:
So, let's start with what we know
The sum of the 2 lesser lengths of a triangle must be greater than the greatest length of a triangle. Otherwise, it cannot be a triangle
a + b > c
Note: variables a and b are the lesser lengths of a triangle, and c is the greatest length.
We are to list out the possible combinations of triangles here with lengths 1, 3, 6, and 8.
So, with the formula above, we will get the combination of
3,6,8
Any other combinations of triangle lengths will not work

33 pies and 46 bottles of juice
42 pies and 37 bottles of juice
I need an answer on how many pies and bottles of juice it is.
Answer:
37 pies and 42 bottles of juice
Step-by-step explanation:
Let x be pies and y be juice
x+y=79 represents # of items sold
1.65x+1.36y=118.17 represents how many of each to make $118.17 based on cost
y=-x+79
1.65x+1.36(-x+79)=118.17
x=37
79-37=42

7 81/1000
The answer is 7081/1000
Step-by-step explanation:
7 = 7×1 = 7×1000/1000 = 7000/1000
7000/1000 + 81/1000 = 7081/1000
this can't be further simplified, as the only factors of 1000 are
2 and 5 and then multiples of them.
neither of them can be a factor of 7081 (which is clearly neither an even number nor a multiple of 5).
At a cost of $8 per pound how many ounces of almonds can be bought for $2.05
Answer:
4.1 Ounces can be bought
Step-by-step explanation:
1 Pound = 16 Ounces
16Oz. = $8
Divide both by the common factor of Eight (8)
16/8 = 2 Oz.
8/8 = $1
2 Oz = $1
1 Oz. = .50
2.05/.50 = 4.1
If each ounce cost .50 cents 4.1x.50 should equals $2.05
and .50x16 should be 8

Well if there are 1000 ml in one L and we have 25 L of of milk and it requires 25 ml of milk per cup of tea we would first convert 25 L to ml to get 25000 ml of milk with that answer we then divide 25000 by 25 to get 1000.
Aaron drew a cone that has a volume of 90in.If Armani drew a cylinder with the same
base and height as Aaron's cone, what is the
volume of her cylinder? Explain your
reasoning.
Answer:
Step-by-step explanation:
A cone has a volume formula of [tex]\frac{1}{3} \pi r^{2} h[/tex]
A cylinder has a volume formula of [tex]\pi r^{2} h[/tex]
So if both of the shapes have the same base and height as in 'h' and 'r' are equal, than the cone has 1/3 the volume of the cylinder.
Thus:
[tex]V_{cone} =\frac{1}{3} V_{cylinder} \\90 = \frac{1}{3} V_{cylinder}\\V_{cylinder} = 270[/tex]
Thus the volume of the cylinder is 270 cubic inches.
Hope that helps!
Answer:
Vol_cylinder = 270 cubic inches
Step-by-step explanation:
Aaron's cone has the Volume
= 1/3BaseArea•height
Armani's Cylinder Volume
= BaseArea•height
The only difference here is the 1/3 in the cone formula.
So the cone volume is 1/3 of the cylinder volume. Or the cylinder volume is 3times the cone volume.
Vol_cone = 90
Vol_cyl = 3•90 = 270
90 is 1/3 of 270.
The cylinder volume is 270 cubic inches.

2x-y=2. Y=2x+1
Answer:
No Solutions
Step-by-step explanation:
1. Substitute the 2x + 1 in for the y in the first equation. Rewrite it as 2x - (2x + 1) = 2.
2. Add the opposite and change the equation to 2x + -1(2x + 1) = 2.
3. Use the distributive to make the equation look like this: 2x + -2x + -1 = 2
4. Combine like terms and add 2x and -2x. They cancel each other out.
5. You will end up with -1 ≠ 2. Since -1 and 2 are not equal, there are no solutions.
