A company packages pencil lead for mechanical pencils.
The pencil lead is packaged in lengths of 0.025 m. How
many of these shorter pieces can be cut from a strip of
pencil lead that is 2.4 m long?
Answers
Answer: 96
Step-by-step explanation:
From the question, we are informed that a pencil lead is packaged in lengths of 0.025 m. To get the number of the shorter pieces can be cut from a strip of pencil lead that is 2.4 m long, we have to divide 2.4 by 0.025. This will be:
= 2.4 / 0.025
= 96
Therefore, 96 shorter pencils can be gotten

Yun Sil added twice as many new songs on her MP3 player as Matt, who added 5 more new songs on his MP3 player than Sierra. The sum of the
songs added on all three players is 15 more than the cube of the number of songs added on Sierra's player. About how many songs are on each
person's player?
Answers
Answer:
Sierra=2songs
Matt=7songs
Yun SIl=14songs
step-by-step explanation:
Step 1
Let,The number of songs YunSil added = x
Number of songs Matt added = y
And number of songs Sierra added = z
Such that Matt has 5more than Sierra =y = 5 +z
Yun SIl has 2 times more thann Matt, x = 2y
x =2(5+z)=10 +2z
Step 2
The expression used to determine number of songs on each player given that the total of songs added on the three players =15 +z^3
Such that
YunSil+Matt+Sierra==15 +z^3
10+2z+ 5+z +z = 15 +z^3
4z +15 = 15 +z^3
4z=15-15+z^3
4z=+z^3
4=z^3/z
4=z^2
Z=√4 =2
Therefore Sierra has z=2songs
Matt has 5+z=5+2=7songs
YunSil has 2(5+z)= 2x7=14songs
The song that are on each person player are as follows;
matt song = 7
Yung Sil song = 14
Sierra song = 2
Let
a = Matt song added
b = Yun Sil song
c = Sierra song =
Therefore,
b = 2a
a = c + 5
(c + 5 + 2a + c) - c³ = 15
(2c + 2(c + 5) + 5) - c³ = 15
2c + 2c + 10 + 5 - c³ = 15
4c + 15 - c³ = 15
4c - c³ = 0
c³ = 4c
c² = 4
c = √4
c = 2
a = 2 + 5 = 7
b = 2(7) = 14

Expand the expression 3(7 + x)
Answers
Answer:
3x + 21 or 21 + 3x
Step-by-step explanation:
Remark
This is an example of the distributive property. Of all the fundamental rules used in solving equations, this is likely the most important, at least at beginning levels.
Solution
What this is saying is two things.
1. you must multiply both terms on either side of the + sign by the factor outside the brackets.
2. You must not destroy a plus (or minus) sign unless the two terms inside the brackets are exactly the same.
3(7 + x) The terms are not the same, so your answer must have a plus sign
Left side of the plus: 3*7
Right side of the plus: 3 * x
The answer then is 21 + 3x
It is more commonly written as 3x + 21

Julio bought 7 science fiction novels (s) and 7 comic books (c) from the bookstore. His purchases can be represented by the expression 7(s + c). Part A: Simplify the expression by using the distributive property. Part B: The cost of a science fiction novel is $5.99 and the cost of a comic book is $6.49. Sales tax is 6%. What is the total amount that Julio spent at the bookstore? Round your answer to the nearest cent. Show your work.
Answers
Answer: See explanation
Step-by-step explanation:
A. 7(s + c)
= 7s + 7c
B. The cost of a science fiction novel is $5.99 and the cost of a comic book is $6.49. Sales tax is 6%. The total amount that Julio spent at the bookstore would be calculated as:
= 7s + 7c
= 7($5.99) + 7($6.49)
= $41.93 + $45.43
= $87.36
We then add tax which will then be:
= $87.36 + (6% × $87.36)
= $87.36 + (0.06 × $87.36)
= $87.36 + $5.24
= $92.60

What is exponential growth factor?
The exponential growth or decay formula is given by
x ( t ) = x₀ × ( 1 + r )ⁿ
x ( t ) is the value at time t
x₀ is the initial value at time t = 0.
r is the growth rate when r>0 or decay rate when r<0, in percent
t is the time in discrete intervals and selected time units
Given data ,
Let the number of birds in 1997 be represented as A
Now , the equation will be
The number of birds in 1995 x₀ = 80 birds
The time n = 1997 - 1995 = 2 years
The percentage of increase r = 5 %
The number of birds A is calculated by exponential growth factor ,
Substituting the values in the equation , we get
x ( t ) = x₀ × ( 1 + r )ⁿ
x ( 2 ) = 80 ( 1 + ( 5/100 ) )²
On simplifying the equation , we get
x ( 2 ) = 80 ( 1 + 0.05 )²
x ( 2 ) = 80 ( 1.05 )²
x ( 2 ) = 80 x 1.1025
x ( 2 ) = 88.2 birds
Therefore , the value of A is 88 birds
Hence , the number of birds is 88 birds

Label ABC with the following information.
AB = 35
AC = 62
Find m/c.
Answers
Answer:
m<C = 34.4 °
Step-by-step explanation:
From the question given above, the following data were obtained:
Opposite = AB = 35
Hypothenus = AC = 62
Angle C =?
The value of m<C can be obtained by using sine ratio as illustrated below:
Sine C = Opposite /Hypothenus
Sine C = 35 / 62
Sine C = 0.5645
Take the inverse of sine
C = Sine¯¹ 0.5645
C = 34.4 °
Thus,
m<C = 34.4 °

Cameron's hourly salary is $13. If Cameron
gets to work in the morning at 9 has lunch
from 12 to 1. and then works until 2. then hou
much did Cameron make that day?
Answers
Answer: 52 dollars
Step-by-step explanation:
Cameron's hourly salary is 13, which means that for each hour she works, she earns 13 dollars.
If she words from 9 - 12, then that is 3 hours. Then she has a lunch break from 12 - 1, and then works again until 2. The time period between 1 and 2 o'clock is 1 hour.
Now we have to add up the total hours that Cameron works. If she worked 3 hours in the morning, and then 1 hour after lunch, then the total is 4 hours. Now we have to mutliply 4 by 13 to find her salary for that day.
4 x 13 = 52. Therefore, Cameron made 52 dollars that day.

Cindy is make a display for a project. She plans on 100 stickers that are 2 inch by 2 inch square on a poster board. The poster board she is using has a length of 3 feet and width of 2 feet. Does she have enough room for all her stickers
Answers
Answer:
YES
Step-by-step explanation:
the dimensions of the poster board has to be converted to inches to add comparability
1 feet = 12 inches
3 x 12 = 36 inches
width = 2 x 12 = 24 inches
Area = length x breadth
36 x 24 = 864 cm^2
area of sticker = 2 x 2 = 4cm^2
Number of stickers that can be put on the board = 864 / 4 = 216
216 is greater than 100. So the board has enough room for the stickers
