A band expects to put 15 songs on their next CD. The band writes and records 20% more songs than
they expect to put on the CD. During the editing process, 50% of the songs are removed. How many
songs will there be on the final CD?
There will be songs on the final CD.
Answers
Answer:
9 songs will be on the final CD
Step-by-step explanation:
The band writes and records 20% more songs than they expected to put on CD (they expected to put 15 on CD) , hence 3 more songs since 20% of 15 is 3 (= 15 × 0.20). A total of 18 songs is recorded.
During editing, 50% of the songs are removed, that is 9 (= 18 × 0.50).
Therefore, only 9 songs are left on CD (= 18 - 9)
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
The number of songs in the final CD is 9.
What is a percentage?
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
The number of total songs.
= 15 + (20% of 15)
= 15 + (1/5 x 15)
= 15 + 3
= 18
Now,
The number of removed songs.
= 50% of 18
= 1/2 x 18
= 9
The number of songs on the final CD.
= 18 - 9
= 9
Thus,
The number of songs in the final CD is 9.

A factory makes tissue boxes. When the net is folded to make the tissue box, the length is 25 cm, the width is 5 cm, and the height is 20 cm. How much cardboard material is used to make each tissue box?
Answers
Answer:
1450 cm
Step-by-step explanation:
A cardboard box is shaped like a rectangular prism.
To solve the above question, we apply the formula for Surface Area of a Rectangular Prism
A=2(wl+hl+hw)
Where
w = width = 5cm
I = length = 25cm
h = height = 20 cm
=2 × (5×25+20×25+20×5)
= 2(125 + 500 + 100)
= 2(725)
=1450 cm of cardboard material should be used.

There are 4 breakfast choices in a school cafeteria: Cereal, Granola Bar, Breakfast Sandwich, and Fruit. The percentage of students that chose cereal is 20%. If 60 students chose cereal, what is the total number of students that ate breakfast?

120
B.
300
C.
320
D.
360
Answers
Answer:
300. In this case, it's very easy to do this percentage inflation. Since 20 is a multiple of 100, and we want to know the 100%, you just multiply the 20 by 5 to make it 100. Along with this, you multiply the 60 by 5 as well, which gives you 300.
Identify the slope and the y-intercept of the following line!
y=-3+x
Answers
Answer:
( 0 , - 3 )
Step-by-step explanation:
Answer:
1.000
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
y-(-3+x)=0
STEP1:
Equation of a Straight Line
1.1 Solve y-x+3 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on a Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y-axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-x+3 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is -3/1 so this line "cuts" the y axis at y=-3.00000
y-intercept = -3/1 = -3.00000
Calculate the X-Intercept :
When y = 0 the value of x is 3/1 Our line therefore "cuts" the x-axis at x= 3.00000
x-intercept = 3/1 = 3.00000
Calculate the Slope :
The slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -3.000 and for x=2.000, the value of y is -1.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -1.000 - (-3.000) = 2.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 2.000/2.000 = 1.000
Geometric figure: Straight Line
Slope = 2.000/2.000 = 1.000
x-intercept = 3/1 = 3.00000
y-intercept = -3/1 = -3.00000

One card from a deck of cards Is selected, it's is replaced, and another card is chosen. What is the probability that the first card is a red card and the second is a diamond
Answers
Answer:
1/ 8
Step-by-step explanation:
Given that:
Number of red cards in deck = 26
Number of diamonds in deck = 13
Number of cards in deck = 52
Recall :
Probability = required outcome / Total possible outcomes
Probability of choosing a red :
P(red) = 26 / 52 = 1/2
With replacement :
Probability of diamond :
P(diamond) = 13 / 52 = 1/4
Hence,
Probability of first card red, then second card diamond equals
P(red) * P(diamond)
1/2 * 1/4
= 1/8

Step-by-step explanation:
4*4*4=64
8*8=64
64+64=128
Answer:
128
Step-by-step explanation:
4 to the power of three is 4x4x4.
8 to the power of 2 is 8x8.
So your new equation would become (4x4x4)+(8x8)
4x4=16, then you have (16x4)+(8x8).
16x4=64. This gives you 64+(8x8).
8x8=64 which means you're doing 64+64 or 64x2.
Whichever equation you use your answer is the same.
64+64=128.
64x2=128.
