A periscope is 5 feet above the surface of the ocean. Through it can be seen a ship that rises to 50 feet above the water. To th
yanalaym [24]

The farthest distance on the planet that the eye can see is given by the formula d=\sqrt{8,000h_1} + \sqrt{8,000h_2}

h_1= your first height and h_2=your second height

Since h_1=5 or the height of the periscope over the water and h_2=50 for the height of the ship the answer is 832.45553203368 feet, but because the question asks to the nearest mile the answer would be 11^a^0

If you get it wrong just tell me and I will rework my math again :-)

If 36a=45/b, then ab=
Ronch [10]

Answer:

1.25

Step-by-step explanation:

let \: a = x \: and \: b = y

36x =  \frac{45}{y}

36xy = 45

xy =  \frac{45}{36}

xy = 1.25

therefore \: ab \: is \: 1.25

Hannah is designing containers to hold 300 cm3 of juice. Which container is more efficient?
Lubov Fominskaja [6]

Answer:

a) 2nd container is more efficient and contains the elements for a container.

b) The cylinder has a........A)Smaller surface area B)bigger C)equal

And will cost.....A)Less to produce B)more C)The same

Step-by-step explanation:

a) The 2nd container has these elements:

Width 20.5cm

Length 6.5cm

side 3.25cm

So, the volume in cubic cm is 20.5 x 6.5 x 3.25 = 433cm3.

This container can hold the 300cm3 of juice.

b) A cylinder is a geometric solid common in everyday life.  Examples of a cylinder are soup cans, food tins, drink cans, candles, toilet paper rolls, cups, aerosol cans, flower vases, test tubes, fire extinguishers, plant containers, salt shakers and pencil holders.  The two ends are called bases, and are usually circular.  Though, they can take other shapes.  When a cylinder is unrolled and flattened out, the side is actually a rectangle.

The surface area of a cylinder is the surface area of each end plus the surface area of the side.  The mathematical formula is 2π * r2, where π is the pie and r is the radius of the end and r2 is r squared..
