A rectangular water tank contains 1440 litres of water. If its length is 120cm and breadth is 80cm, find the height of the water level in the tank.(1 litre=1000cm cube.)

Answers

Answer:

Answer is 150cm

Step-by-step explanation:

Here

l = 120cm

B = 80cm

Rectangular tank contain 1440l of water

As as we know 1l = 1000cm^3

So 1440l = 1440000cm^3

Here,

volume of tank( volume of water) = l *b* h

or, 1440000cm^3= 120cm*80cm* h

or, 1440000cm^3= 9600cm^2* h

h = 150cm

volume of tank( volume of water) = l *b* h

or, 1440000cm^3= 120cm*80cm* h

or, 1440000cm^3= 9600cm^2* h

h = 150cm

Answers

Answer:

421.35

Step-by-step explanation:

Henry spends $50.00 on lunch, $12.00 on a cap and spends $6.00 on bananas. Hicks spend $120.00 on clothes and $15 on a cap. Henry borrowed money from Hicks to buy his items. In other words, Hicks paid for Henry. Lucky for Hicks he had a discount coupon for 10% off his lunch. Hicks bank account has a balance of $225.

A. How much will the purchase cost him

b. What would Hick’s bank balance be after all the debts were paid?

Answers

Answer:

The purchase will cost him $158.

Hick's bank balance would be $67 after all the debts were paid.

Step-by-step explanation:

10% of $50= $5.

$120.00 + $15.00 + $12.00 + $6.00 + 5.00= $158

$225 - $158 = $67

Which sentence is true?
All whole numbers are also natural numbers.
b All integers are also rational numbers.
All rational numbers are also integers.
d. All integers are also whole numbers.

Answers

Answer:

Natural numbers are all numbers 1, 2, 3, 4… They are the numbers you usually count and they will continue on into infinity.

Whole numbers are all natural numbers including 0 e.g. 0, 1, 2, 3, 4…

Integers include all whole numbers and their negative counterpart e.g. …-4, -3, -2, -1, 0,1, 2, 3, 4,…

All integers belong to the rational numbers. A rational number is a number

ab,b≠0

Where a and b are both integers.

Example

The number 4 is an integer as well as a rational number. As it can be written without a decimal component it belongs to the integers. It is a rational number because it can be written as:

41

or

82

or even

−8−2

Whereas

15=0.2

is a rational number but not an integer.

A rational number written in a decimal form can either be terminating as in:

15=0.2

Or repeating as in

56=0.83333...

All rational numbers belong to the real numbers.

If you look at a numeral line

picture05

You notice that all integers, as well as all rational numbers, are at a specific distance from 0. This distance between a number x and 0 is called a number's absolute value. It is shown with the symbol

|x|

If two numbers are at the same distance from 0 as in the case of 10 and -10 they are called opposites. Opposites have the same absolute value since they are both at the same distance from 0.

|10|=10=|−10|
