To multiply exponents, you add them. To divide exponents, you subtract them. The answer would be 5 to the power of -3. However, we need to change that. 5 to the power of -3 is equal to 1 divided by 5 to the power of 3. 1 divided by 5 to the power of 3 is correct.

Answer:

113.04 cubic units. ".04" is four hundredths.

(the units are not given here. They could be cubic feet, cubic inches, cubic meters, cubic centimeters. or other measurements.)

Step-by-step explanation:

To find volume we need to multiply the area of the base times the height.

The base of a cylinder is a circle.

The area is πr²

The given radius here is 3

3² is 9

π × 9 using 3.14 is 28.26

Multiply that area by the given height, 4

28.26 × 4 = 113.04

The volume if this cylinder is 113.04 cubic units.

Shishir bought 4000 orange at 70 paisa each. But 400 of them were rotten. He sold 2000 oranges at 90 paisa each.If he plans to m

Ipatiy [6.2K]

Answer:

He needs to sell the rest of the oranges at 75 paisa each.

Step-by-step explanation:

Consider the given information that, Shishir bought 4000 orange at 70 paisa each.

Note: 1 rupees = 100 paisa

Thus, 70 paisa = 70/100 rupees = 0.70 rupees

Therefore, the cost price of 4000 oranges is:

4000×0.70 rupees = 2800 rupees

The selling price of 2000 oranges is:

2000×0.90 rupees = 1800 rupees

The number of oranges now Shishir have:

4000 - 2000 - 400 = 1600

He wants to make a profit of RS 200. Thus the selling price of 4000 oranges should be:

2800 rupees + 200 rupees = 3000 rupees

He earned 1800 rupees by selling 2000 oranges at 90 paisa. So, the remaining amount that he needs to make with 1600 oranges is:

3000 rupees - 1800 rupees = 1200 rupees

Therefore, the cost of one orange is:

1600 oranges = 1200 rupees

1 orange = 1200/1600 rupees

1 orange = 0.75 rupees

Hence, he needs to sell the rest of the oranges at 75 paisa each.

The Sognefjord is the deepest fjord in Norway at 1,308 metres (4,291 ft) If a submersible floating on the surface was to dive ve

natali 33 [55]

Answer:

36 minutes

Step-by-step explanation:

Depth of the fjord = 1308 m

Rate at which the submersible dives = 35 meters/minute

Distance to the bottom of the fjord should be 48 m

Distance the submersible has to go underwater is $1308-48=1260\ \text{m}$

Time is found by dividing the distance the submersible has to go underwater by rate at which the submersible dives

$\dfrac{1263}{35}=36\ \text{minutes}$

The time taken by the submersible to dive the required distance is 36 minutes.
