Grace buys notebooks at a price of four for $5 and sells them at a price of three for $6. How many notebooks must she sell in order to make a profit of $120
Answers
Answer:
125 I think
I'm a lil slow
Grace needs to sell 160 notebooks to make a profit of $120
What is an equation?Two algebraic expressions having the same value and the symbol '=' in between are called as an equation.
Given:
Grace buys notebooks at a price of four for $5.
Unit cost price,
= $5 / 4
= $1.25
And sells them at a price of three for $6.
Unit cost price,
= 6/3
= $2.
Profit = sales - cost
So, the equation,
120 = 2x - 1.25x
0.75x = 120
x = 120/0.75
x = 160
Therefore, 160 notebooks need to sell to maker profit of $120.

Write the scientific notation for 127.5. Please! And tell me how so I can learn too.
Answers
In scientific notation, you move the decimal place until you have a number between 1 and 10. Then you add a power of ten that tells how many places you moved the decimal. In scientific notation, so 127.5 becomes 1.275 x 10 to the second power.

Answers
Answer:
80 silver, 8 red
Step-by-step explanation:
let x be the number of red cars then 10x is the number of silver cards , so
x + 10x = 88
11x = 88 ( divide both sides by 11 )
x = 8
10x = 10 × 8 = 80
There are 80 silver cars and 8 red cars

12. A jet stream can move a particle of air
11 miles in 5 minutes. At this rate, how far
will the particle move in 1 hour?
(5 minutes = 1 hour) (Example 1)
Answers
Answer:
132 particles
Step-by-step explanation:
5 minutes = 11 miles
1 hour (60 minutes)
11*x = 11 x 60 = 660
11x = 660/5=132
The distance of a jet stream can move a particle of air 132 miles in 1 hour.
Here,
A jet stream can move a particle of air 11 miles in 5 minutes.
We have to find, The distance of particles move in 1 hour.
What is distance?
The length along a line or line segment between two points on the line or line segment.
Now,
A jet stream can move a particle of air 11 miles in 5 minutes.
5 minutes = 11 miles
Then, for 1 minute a jet stream can move a particle of air = 11 / 5 miles
Hence, In 1 hour ( 60 minutes) a jet stream can move a particle of air;
⇒ [tex]\frac{11}{5} * 60 = 132[/tex]
So, The distance of a jet stream can move a particle of air 132 miles in 1 hour.

a.) The highest monthly rent
b.) The average monthly rent.
c.) The most frequent monthly rent.
d.) The spread of the monthly rents
Answers
The property that they would never be affected by is the most frequent monthly rent. Option C is correct.
Given that,
Kate collected a sample of monthly rents and recorded the following numbers: $500, $525, $550, $600, $600, $750, $775, $800, $1350. Kate drops the unusually high rent of $1350 from the data set, which of the following would not be affected is to be determined.
The statistic is the study of mathematics that deals with relations between comprehensive data.
Here,
If the rent of $1350 is dropped by Kate, definitely affect the average, highest monthly rent, and the spread of the monthly sheet, but it won't affect the most frequent monthly of rent because the most frequent rent is $600.
Thus, the property that they would never be affected by is the most frequent monthly rent. Option C is correct.
