Answer:
7/20 of the lawn still needs to be mowed.
The son mowed most of the lawn 7/20 of the lawn still needs to be mowed.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
Mrs. jones mowed 2/5 of her lawn and her son mowed 1/4 of it.
Now, Size of the lawn mowed by Miss Jones = 1/4
And, Size of the lawn mowed by her son = 2/5
To know who mowed the most lawn, find the LCM of the denominators.
The LCM of 4 and 5 = 20
Make the denominators of both fractions to be 20
Hence, Size of the lawn mowed by Miss Jones = 1/4 x 5/5 = 5/20
And, Size of the lawn mowed by her son = 2/5 x 4/4 = 8/20
Since, 8/20 > 5/20, Miss Jones son mowed more part of the lawn than Miss Jones.
Hence, The part of the lawn still needs to be mowed is,
⇒ 1 - 1/4 - 2/5
⇒ 7/20

A light bulb manufacturing process results in 6% of the light
bulbs being defective. If 5 light bulbs are randomly
selected, find the probability that all of the light bulbs are
fully functioning.
Answer:
[tex]Probability = 0.734[/tex]
Step-by-step explanation:
Given
Represent the event that a bulb is defective with p.
So:
[tex]p =6\%[/tex]
Required
Determine the probability that all 5 are fully functioning
Represent the event that a bulb is defective with q.
So:
[tex]p + q = 1[/tex]
Make q the subject
[tex]q = 1 - p[/tex]
Substitute 6% for p
[tex]q = 1 - 6\%[/tex]
Convert % to decimal
[tex]q = 1 - 0.06[/tex]
[tex]q = 0.94[/tex]
If 5 were selected and all are functioning, the event is represented as: q q q q q
And the probability is:
[tex]Probability = q * q * q * q *q[/tex]
[tex]Probability = q^5[/tex]
Substitute 0.94 for q
[tex]Probability = 0.94^5[/tex]
[tex]Probability = 0.7339040224[/tex]
[tex]Probability = 0.734[/tex] --- approximated

3(2-5) – (4w=11)
Answer:
-5 = w
Step-by-step explanation:
3(2-5) – (4w=11)
Distributive property
6 - 15 - 4w = 11
Combine like terms
-9 - 4w = 11
Add 9 on both sides
-9 + 9 - 4w = 11 + 9
-4w = 20
Divide by -4 on both sides to isolate the variable
-4w/-4 = 20/-4
w = -5

Step-by-step explanation:
Morning is 4 hr 15 min
afternoon is 4 hour 15 min
together is 8 hour 30 min
8.5*14 = 119 dollars
According to the unitary method, the wage of the weekly time for the employee is written as $119.00
To calculate the hours worked on Monday, we need to consider both the morning and afternoon shifts. For the morning shift, the employee clocked in at 08:00 AM and clocked out at 12:15 PM. The total time worked in the morning is 4 hours and 15 minutes (12:15 - 08:00).
Similarly, for the afternoon shift, the employee clocked in at 01:00 PM and clocked out at 05:15 PM. The total time worked in the afternoon is 4 hours and 15 minutes (05:15 - 01:00).
Adding both morning and afternoon hours, the total hours worked on Monday is
(4 hours 15 minutes + 4 hours 15 minutes) = 8 hours and 30 minutes
To perform the calculation, we need to convert the minutes to decimal hours. There are 60 minutes in an hour, so we divide the minutes by 60 to get the decimal representation. In this case, 30 minutes is equal to 0.5 hours.
Now that we have the total hours worked on Monday, we can calculate the pay. We multiply the total hours worked by the hourly wage. In this case, the hourly wage is $14/hr.
So, the pay for Monday would be:
Pay = Total hours worked x Hourly wage
Pay = 8.5 hours x $14/hr = $119.00

0.5 is a rational number.
True
False
Answer:
true
Step-by-step explanation:
Natural numbers are numbers naturally occurring in nature like 1, 2, 3, 4, 5, 6, 7, 8, 9 . . .
Whole numbers are numbers that are whole, like 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 . . . (the only difference is that there is a 0 included)
Integers include negative and positive numbers like -3, -2, -1, 0, 1, 2, 3, 4 . . .
Rational numbers are include all of the above AND anything that can be turned into a fraction, like fractions and decimals (that have an end) like 0.625, -0.5, 1, 4, 1/4, 6/15, 4.8, etc.
So in this case, yes, 0.5 is a rational number.

All you really have to do is multiply 1/5 and 3/4. We can separate her backyard in 5 equal parts. In one of those parts, we have her garden, and we break it down into 4 pieces, and make three of those tomato gardens. Now if we break all 5 parts of her backyard into 4 pieces, we can double check our answer, and see that there are 20 pieces, but only 3 have tomatoes. Of course, that's only to double check, but you could also use this method as a model.
