What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

1. 5 + 0 = 0

5 = 0

This is not an equation because LHS ≠ RHS.

2. 15 x 0 =0

0= 0

This is an Equation.

3. 1.4 + 2.7 = 4.1

4.1 = 4.1

This is an Equation.

4. 2/3 x 5/9 = 7/12

10/ 27= 7/12

This is not an Equation.

5. 4 2/3 = 5- 1/3

A cashier can ring up 12 items per minute. How long will it take the cashier to ring up 72 items? ​

Answers

Answer:

So it will take 6 minutes to ring up 72 items.

Step-by-step explanation:

Well this seems pretty simple just have to reads the question and know what to find.

So what we know :

A cashier can ring up 12 items per minute

So :

1 minute = 12 Minutes

And we have to find :

How long for 72 items

So since we know he can do 12 in a minute and it is asking how many minutes it will take for 72 we can divide.

So :

72 / 12

=

6

So it will take 6 minutes to ring up 72 items.

find the distance of a cord 8cm from the centre of a circle of a radius 5 cm​

Answers

Answer:

d = 3 cm

Step-by-step explanation:

Given that,

The distance of a cord, c = 8 cm

The radius of the circle, r = 5 cm

Half of the cord = 4 cm

We need to find the distance of a cord from the centre of the circle. We can find it using Pythagoras theorem,

[tex]5^2=d^2+4^2\\\\d^2=25-16\\\\d=3\ cm[/tex]

So, the required distance is 3 cm.
