Find the perimeter of the figure below. Notice that one side length is not given.

olganol [36]

Answer:

48 cm

Step-by-step explanation:

The perimeter of the figure is the sum of the lengths of its sides.

Find the length of the unknown side

Let the unknown length be x cm.

Notice that the sum of the lengths of the unknown side and the side measuring 5 cm I equal to the length of the side measuring 9 cm.

x +5= 9

<em>Subtracting 5 from both sides:</em>

x= 9 -5

x= 4

Add up the lengths of all of the sides to find the perimeter. I will add the lengths starting from the side measuring x cm (or 4 cm), and sum them up in a clockwise manner. This ensures that none of the sides are overlooked.

Perimeter of the figure

= 4 +15 +9 +7 +5 +8

= 48 cm

A particular dam contains approximately 1,900,000,000,000 cubic feet of water. for a week long spike flood, the dam released at

Fantom [35]

Answer:

a) How much water was released during the flood?

14878080000 cubic feet or 14,878,080,000ft³

b) What percentage of the dam was released during the flood?

0.78%

Step-by-step explanation:

a) How much water was released during the flood?

The first step would be to find out how many seconds are in a week

60 seconds = 1 minute

60 minutes = 1 hour

24 hours = 1 day

7 days = 1 week

Hence, the number of seconds in a week =

1 week × (7 days/1 week)× (24 hours/1 day )×( 60 minutes/1 hour) ×( 60 seconds/1 minute)

= 604800 seconds

Therefore, the quantity of water released per week =

604800 seconds × 24,600 cubic feet per second

= 14,878,080,000 cubic feet or 14,878,080,000ft³

b) What percentage of the dam was released during the flood?

This is calculated as quantity released during the week ÷ Quantity of water in the dam × 100%

Quantity of water released during the flood in a week = 14,878,080,000 cubic feet

Quantity of water in the dam= 1,900,000,000,000 cubic feet of water

Percentage of the dam released during the flood =

14,878,080,000 cubic feet ÷ 1,900,000,000,000 × 100

= 0.7830568421%

Approximately = 0.78%

When a whole number is multiplied by 10 to the power of 4 how does the placement of the decimal point change

Wittaler [7]

9514 1404 393

Answer:

The decimal point moves 4 places to the right

Step-by-step explanation:

Take a simple case using the whole number 3.

3. — whole number we're starting with

3.×10^4 = 3.×10,000 = 30,000. — multiplied by 10^4

The decimal point moves 4 places to the right.

_____

<em>Additional comment</em>

Multiplying be a positive power of 10 moves the decimal point a number of places equal to that power. Effectively, the number of zeros added on the right is equal to the power of 10. Above, you will notice multiplying by 10^4 added 4 zeros to the right of the number.
