Using unit measurement concepts, it is found that the correct options are:
The distance for a flight from Georgia to Texas to the nearest mile.Measuring how long the large mouth bass you caught while fishing to the nearest foot. The number of party favors needed for a birthday party by the whole number.The cost of new laptop plus tax calculated to the nearest tenth.----------------------------------
When measurements are made, the unit used is a big consideration, to give accuracy to the measurement. For example, measuring a person's height is kilometres would not give an accurate representation.----------------------------------
In the first option, for distance between cities or states, miles is the most widely used metric, so this option is correct.In the second option, heights of mouth bass are usually measured in inches, which is easily converted to feet(dividing by 12), and thus, this option is correct.In the third option, for each person, there is usually a favor, thus, whole number is an accurate metric, and this option is correct.In the fourth option, volume of water is usually measured in liters, and fluid ounces are way smaller than liters, thus not giving an accurate representation.In the fifth option, costs of products, especially expensive products such as laptops, are rounded to the nearest tenth, and thus, this option is correct.A similar problem is given at https://brainly.com/question/16563559

A piece of string is 1650 cm long.
It is cut into two unequal pieces.
One piece is 150 cm longer than the other.
How long is the smaller piece?
Answers
Answer: The smaller piece is 750m long.
Step-by-step explanation:
let the smaller piece be x
so
150m + x + x = 1650
150 + 2x = 1650
or, 2x = 1500
so, x = 750 m

What is an equation of the line that passes through the points (-5, -8)(−5,−8) and (-4, -6)(−4,−6)?
Answers
Answer:
Step-by-step explanation:
General equation of a line is y= mx+b,
where m is the slope and b is the y- intercept
For points (-5, -8) and (-4, -6) the slope is
m= difference in y / difference in x
m = [-6 - (-8)] / [-4 - (- 5)] = (-6+8)/(-4+5) = 2/1 =2
Now we know that y= 2x+b , to find b substitute the coordinate (x, y) with coordinate (-4, -6) -you could pick the other point if you want will work because both points are on the line.
-6 = 2(-4) +b , multiply
-6 = -8 + b, add 8 to both sides
-6+8 =b , add
2 =b
The equation of the line that passes through the points (-5, -8) and (-4, -6) is
y= 2x+2
First of all, you will find the gradient. The formula for finding the gradient is y2-y1 /x2-x1. - 6--8/-4--5.If two negatives meet they change to positive. - 6+8/-4+5=2/1,therefore the gradient is 2,after that then you will find the equation of the line. The formula for finding the equation of the line is y-y1=m(x-x1). y-(-8)=m(x--5),y+8=2(x+5),y+8=2x+10,y=2x+2.

- 8/5
Step-by-step explanation:
m = slope
m = change in y/change in x

m = -7 - 1/3 - -2
m = -8/5
m = - 8/5
The slope is - 8/5

7. Fuji the woodworker sells cribs. His start-up
costs total $2000. Labor and material for
each crib cost $185. If the formula for his
Cost(C) based on (n) number of cribs is:
C=2000 + 185n , Tell what the rate of change
is and what it tells us about Fuji's expenses.
Answers
Answer:
The rate of change is 185.
It tells us that Fuji's expenses increase by $185 for each additional crib made.
Step-by-step explanation:
In a linear equation, the rate of change is the change in y over the change in x.
In this situation, that means how much the cost will change based on the amount of cribs that Fuji has to make.
Since labor and material costs for each crib cost $185, 185 is the rate of change.
For every additional crib that Fuji makes, the cost will increase by $185.
So, the rate of change is 185 and it tells us that Fuji's expenses increase by $185 for each additional crib made.

Miguel Sebring took out a loan for $5,000 at 9.5% exact interest for 90 days. How much interest will Miguel pay?
Answers
Answer: Miguel will pay Rs 11,875.
Step-by-step explanation:
P = 5,000
R = 9.5%
T = 90 days
now changing time into years
360 days = 1 year
90 days = 1/360 * 90 = 1/4 years = 0.25 years
now
I = PTR/100
= (5,000*9.5*0.25)/100
= 11,875

Absolute value of 6.4 is 6.4 itself.
What is the number line?A horizontal line with evenly spaced numerical increments is called a number line. How the number on the line can be answered depends on the numbers present. The use of the number is determined by the question that if corresponds to, such as when graphing a point.
Since, Absolute value describes the distance from zero that a number is on the number line, without considering direction. The absolute value of a number is never negative.
Thus, the absolute value of a positive number is always positive
Therefore, the Absolute value of 6.4 is 6.4.
