15% of 45 is 0.15 x 45 or 6.75 feet. That's how far the submarine descended in 1 minute. So, in 4 minutes the submarine would be 4 x 6.75 feet down which is 27 feet.
Answer:
1/6 more ads.
Step-by-step explanation:
1/2
2/6 is only 1/6 away from 3/6, which is 1/2
Answer:
A 1/6
Step-by-step explanation:
i got this because if you add all the marbles it is 12 so the real percentage would be 3/12 but they divided it by 2 to get 1/6
You need to split the shape into simpler shapes so you would get a rectangular prism and a triangular prism finding the volume is pretty straightforward the formula is
Volume of a triangular prism = area of base triangle × height
The formula for finding the volume of a rectangular prism is the following: Volume = Length * Height * Width, or V = L * H * W.
After solving for this you would just have to add the 2 shapes volume together tie get the volume of the composite figure
Finding the surface area is also pretty simple since it would only require you to know the formulas
S = 2(lw + lh + wh) to find the surface area of a rectangle or prism
A=12bh is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height.
And by adding the two surface areas of the shapes you can get the surface area of the composite figure but remember to subtract the top face of the rectangular prism and the bottom face of the triangular prism

Answer: 2y + 3x = -8.
Step-by-step explanation:
Given our first equation 2x-3y =13, we rewrite in the form of equation of a line, i.e y = mx + c
Where m is the slope of the line and c is the intersection on y axis.
By rewriting, we have...
3y= 2x-13
y= 2x/3 - 13/3.
m= 2/3, c= -13/3.
For two perpendicular lines, the product of their gradients is -1
i.e
m¹ * m² = -1
Hence m² = -1 * 3/2
m² = -3/2.
Hence, to get the equation of the line passing through the point (-6,5) we first find the intersection when x=0 given as
[Y-c]/[x-0] = -3/2
2y - 2c = -3x
2(5) - 2c =- 3(-6)
10-18= 2c
C = -8/2
C= -4
Then the equation is given as
y = mx + c
y = [-3/2]x - 4
2y= -3x - 8
2y + 3x = -8.
