You are mowing a lawn. After 12 minutes, 52% of the lawn still needs mowed. How long does it take to mow the entire lawn? Write an equation that represents the percent y of the lawn that still needs mowed after x minutes.

Answers

The time taken to mow the entire lawn will be 23 minutes.

Let the total time taken be represented by x.

Based on the information given, the total time needed will be:

52% × x = 12

0.52 × x = 12

0.52x = 12

x = 12/0.52

x = 23.08

Therefore, the time taken to mow the entire lawn will be 23 minutes.

If u need to give a customer 7.94 in change how many dimes should u give as part of the change

The number of times to give as a change is given by the equation D = 79

What is an 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.

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.

Given data ,

Let the equation be represented as D

Now , the value of D is

The total amount of money = $ 7.94

The value of 1 penny = $ 0.01

The value of 1 nickel = $ 0.05

The value of 1 dime = $ 0.10

The value of 1 quarter = $ 0.25

So , the amount $ 7.94 can be given as a change in different ways such as

The amount $ 7.94 = 79 dimes + 4 pennies

On simplifying the equation , we get

The amount $ 7.94 = ( 79 x 0.10 ) + ( 4 x 0.01 )

The amount $ 7.94 = 7.9 + 0.04

The amount $ 7.94 = $ 7.94

Therefore , the value of D is 79 dimes

Hence , the number of dimes is 79 dimes
