The answer as a decimal to the nearest hundredth is -3.45.
What is termed as the decimals?A decimal is a number with a whole as well as a fractional part. Decimal numbers are between integers but also reflect numerical value for whole plus some fraction of a whole. A decimal number has two parts: a whole number component and a fractional component. A decimal place value system is identical to the whole number value system for the entire part of a decimal number.For the given question;
The expression is given as;
= -3.7 + 1/4
Now, the fraction 1/4 can be written in decimal as 0.25.
Put the value of 1/4.
= -3.7 + 0.25
The subtraction of larger negative to smaller positive gives negative number.
= -3.45
Thus, the answer as a decimal to the nearest hundredth is -3.45.

{(-6,7),(4,-9),(5,2),(-5,9),(8,-8)}
Domain:_____
Range:_____
Funtion or not:________
The domain of the set of ordered pairs is {-6, 4, 5, -5, 8,} and the range is {7, -9, 2, 9, -8)} which are represented as a function.
What are the domain and the range of a set of ordered pairs?The domain of a set of ordered pairs includes all possible x values of a function, and the range includes all possible y values of a set of ordered pairs.
Given the set of ordered pairs as :
{(-6,7),(4,-9),(5,2),(-5,9),(8,-8)}
Since the domain is the set containing the x-coordinates of all ordered pairs.
So the domain = {-6, 4, 5, -5, 8,}
And the range is the set containing the y-coordinates of all ordered pairs.
So the range = {7, -9, 2, 9, -8)}
Thus, the domain of the set of ordered pairs is {-6, 4, 5, -5, 8,} and the range is {7, -9, 2, 9, -8)}. which are represented as a function.

Greg earned $32 dollars for washing cars this month. He earned twice as much for washing cars than he did for mowing lawns. Write an equation to determine how much he earned for mowing lawns.
2m = 32
m + 2 = 32
m − 2 = 32
m over 2 equals 32
Answer: the correct answer is 2m = 32
Step-by-step explanation: If Greg earned $32 for washing cars and that was twice as much for mowing lawns, then you will need to divide that amount by 2 to find out what was made.
2m = 32
Divide each side by 2:
2m/2 = 32/2
m = 16
The amount for mowing lawns = $16
Answer:
Determine which equation is false, based on the solution set S:{4}.

Jill is a hotel desk clerk her regular pay is 9.85 per hour time and a half for all hours worked over 40 and doubled time on Sunday she worked the following hours this pay period. what is her over time pay and her gross pay
Jill's overtime pay is $137.9 and her gross pay is $531.9
For calculating, Hourly and overtime pay
Some employers pay a set amount for every hour an employee works. This is called regular pay. An employee may also earn overtime pay for all hours worked over 40 within a pay period. The overtime rate is usually 1.5 times an employee’s regular hourly pay.In some cases, such as on Sundays, an employer may pay double time or 2 times an employee’s regular pay.
Formulas for calculating earnings,
Hours Worked x Hourly Rate = Regular Pay
Overtime Hours Worked x Overtime Rate = Overtime Pay
Regular Pay + Overtime Pay = Gross Pay
Jill work for one day = 8 hours
She work from Monday to Friday i.e, 5 days which is = 8 * 5 = 40 hours
On Saturday and Sunday she worked 4 hours on each day,
so, for Saturday her payment is = (1.5 * 9.81) * 4
= 59.1
And, for Sunday her payment is = 2 * ( 4 * 9.85)
= 78.8
Now, find her overtime pay (add her's Saturday and Sunday payment)
Overtime pay = 59.1 + 78.8
= $137.9
Now, find her Gross pay = Regular pay + Overtime pay
Regular pay = 9.85 * 40
= 394
So, the Gross pay = 394 + 137.9
= $531.9
Therefore, Jill's overtime pay is $137.9 and her gross pay is $531.9.

In 3–5 sentences, explain why the moon appears to be less bright than the sun despite its very close distance to Earth. PLEASE HELP A GIRL OUT THIS IS A VERY IMPORTANT TEST I DO NOT WANT TO FAIL make it simple
Step-by-step explanation:
Based on scientific observations and findings, the reasons the moon appears to be less bright than the sun despite its very close distance to earth are the following:
Moon doesn't produce its light but rather takes or reflects the light from the Sun.
Moon only reflects about 12 percent maximum of lights that shines on it from the sun.
Externally, Moon is made of dark-colored soil often referred to as lunar soil. This is unlike the Sun which is made of hydrogen and helium, whose atoms are very light.
Also, Sun is about 400 times bigger than the Moon.
Hence, in this case, it is concluded that there are many reasons the moon appears to be less bright than the sun despite its very close distance to earth.
Polly assumes that the rice from two sacks will fill twice as many bags as the rice from
one sack.
(b) Is Polly correct?
You must give a reason for your answer.
Yes, Polly is right. 28 bags can be filled.
How to find the number of bags that can be filled?Polly has a full 5 kg sack of rice.
Each full bag contains 350 g of rice.
Solution:
5 Kg is 5000g.
Therefore,
5000/350 = 14.29
That is 14 bags in total.
Polly assumes that the rice from 2 sacks will fill twice as many bags as the rice from 1 sack.
Therefore,
2 * 5000/350 = 28.57 bags which is twice 14 bags.
Therefore, her assumption is right.

After solving the basic fractions, Katrina needs to chop 7/3 cups of onions more to cook the onion soup recipe.
What is fractions?In mathematics, a fraction is represented as a numerical value that defines a portion of a whole. A fraction is a portion or section of any quantity taken from the whole, which can be any number, a specific value, or a thing.
Let us use an example to demonstrate this point. The image below shows a pizza that has been divided into eight equal parts. Now, if we want to express one specific part of the pizza, we can do so as 1/8, which indicates that we are referring to one part out of eight equal parts.
It translates to one in eight equal parts. It can also be written as:
1/8, also known as 1 by 8
We have given that Katrina had already chopped cups onions = 1⅓
= 4/3
The onion soup recipe needs chopped onions = 3⅔
= 11/3
Let the number of cups of onions Katrina still needs to chop be x
This gives us the equation
x + 4/3 = 11/3
Lets solve for x
x = 11/3 - 4/3
x = (11 - 4)/3
x = 7/3
So, Katrina needs to chop 7/3 cups of onions more to go.

After 3.94 hours, the price of stock A and stock B will become same.
What do you mean by price?
Price can be defined as the amount of money that get paid for something.
Lets assume that after x hours the price of stock A is equal to price of stock B.
Since the price of stock A is increasing at rate of 0.11 per hour, so after x hours it will become:
$12.15 + 0.11x
Since the price of stock B is decreasing at rate of 0.08 per hour, so after x hours it will become:
$12.90 - 0.08x
Equating both price to get the value of x:
12.15 + 0.11x = 12.90 - 0.08x
(0.11+0.08)x = 12.90 - 12.15
x = 0.75/0.19
x = 3.94
Hence, after 3.94 hours the price will be same.

What is an equation of the line that passes through the points (2, 6) and ( -2, -4)?
Answer:
y = (5/2)x + 1 or
y = 2.5x + 1
Step-by-step explanation:
The slope-intercept form of the equation of a line is
y = mx + b
where m = slope, b = y-intercept
Slope = rise / run
where rise is the difference in y-values of two points on the line and run = difference in x values for the same two points'
Here the points are (2, 6) and (-2, -4)
rise = 6 - (-4) = 6 + 4 = 10
run = 2 - (-2) = 2 + 2 = 4
Slope = 10/4 = 5/2
Equation is
y = (5/2))x + b
To calculate b, plug in x, y values for (2, 6) to get
6 = (5/2) x 2 + b
6 = 5 + b
b = 6 - 5 = 1
Equation of line is
y = (5/2)x + 1
when jess is mailing a jewelry box to a customer, she packs it inside a larger shipping box. The sides of a shipping box are 2 inches longer than the sides of a jewelry box
The volume of the jewelry box is 8 cubic inches. Volume exists as a measurement of three-dimensional space that is occupied.
What is meant by volume?Every three-dimensional object requires some amount of space. The volume of this space is measured. Volume is defined as the space occupied by an object within the boundaries of three-dimensional space. It is also known as the object's capacity. The basic formula for volume is length × width × height, whereas the basic formula for area of a rectangular shape is length width height. The calculation is unaffected by how you refer to the various dimensions: you can, for example, use 'depth' instead of 'height.' A 3D object's volume is the amount of physical space it occupies. It is the 3D equivalent of a 2D shape's area.
Therefore,
The computation of the volume of the jewelry box is shown below:
The Volume of the jewelry box = Length × height × weight
∴ 2 × 2 × 2 = 8
