Luke, Kira and Ali each served 2/3 of their own cake. Each cake was the same size, but luke served 4 slices, Kira served 6 slices and Ali served 8 slices. How is this possible?
Answer:
The whole slices of the cakes of Luke, Kira and Ali are 6, 9 and 12 respectively. So it is possible.
Step-by-step explanation:
It's possible because they cut cakes into different number of slices.
You know that Luke, Kira and Ali each served [tex]\frac{2}{3}[/tex] of their own cake and Luke served 4 slices, Kira served 6 slices and Ali served 8 slices.
Being x the whole slices of cake, and if Luke served [tex]\frac{2}{3}[/tex] of his cake, which are 4 slices, the whole slices of cake of Luke is:
[tex]\frac{2}{3}*x=4 slices[/tex]
Solving:
x= 4 ÷[tex]\frac{2}{3}[/tex]
x= 6
Then, whole slices of Luke's cake is 6.
Performing the same approach for Kira you get:
[tex]\frac{2}{3}*x=6 slices[/tex]
x= 6 ÷[tex]\frac{2}{3}[/tex]
x= 9
Then, whole slices of Kira's cake is 9.
Finally, performing the same approach for Ali you get:
[tex]\frac{2}{3}*x=8 slices[/tex]
x= 8 ÷[tex]\frac{2}{3}[/tex]
x= 12
Then, whole slices of Ali's cake is 12.
The whole slices of the cakes of Luke, Kira and Ali are 6, 9 and 12 respectively. So it is possible.

Sally used 8 cubes to make this square frame that has 3 cubes on each side. If she uses 20 cubes to make a square frame, how many cubes will be on each side of the frame? Think of using objects to help you solve this problem.
Answer:
5
Step-by-step explanation:
The number of cubes that should be on each side of the frame should be considered as the 5.
Calculation of the number of cube:Since Sally used 8 cubes to make this square frame that has 3 cubes on each side.
So here the no of the cube be like
= 8 - 3
= 5
hence, The number of cubes that should be on each side of the frame should be considered as the 5.

A shop has 400 bulbs
out of which 24 are defective What percent are good bulb?
Answer:
look at the picture i sent plz......
Answer:
Number of non defective bulbs-
400-24
376
Our fraction would be-
376/400
To make it into percentage we need to always multiply it by 100
376/400 x 100
=94%
Thus 94% of the bulbs are non defective
You are in charge of designing your soccer team’s shirts and have narrowed it down to two companies. Master Ink has a flat rate of $35 and charges $12 for each t-shirt printed. Totally Tee has a flat rate of $55 and charges $8 for every t-shirt.
Answer:
Step-by-step explanation:
Since there official question included with this, here is both equations and the point at which they equal the same amount.
Let x be every t-shirt printed.
Master Ink: 35+12x
Totally Tee: 55 + 8x
The point of which both equals the same (no matter how many shirts you buy) means that Master Ink = Totally Tee, therefore:
35+12x = 55+8x Solve
4x=20
x = 5
For the cost from both companies to be the same, you can buy 5 shirts. I would recommend Master Ink if you want to buy 5 shirts or less, and Totally Tee, for 5 shirts or more if you want to buy the cheapest offer.
The mean of three numbers is 10. The mean of other four numbers is 12. Find the mean of all the numbers.
Answer:
11.14
Step-by-step explanation:
Mean = sum of numbers / total numbers
the mean of the 7 numbers = sum of the numbers / 7
sum of numbers for the 3 numbers = 10 x 3 = 30
Sum of numbers for the other 4 numbers = 12 x 4 = 48
Sum of the 7 numbers = 48 + 30 = 78
Mean of the 7 numbers = 78 / 7 = 11.14

The mean age of 5 people in a room is 26 years.
A person enters the room.
The mean age is now 33.
What is the age of the person who entered the room?
The mean age of 5 people in a room is 26 years. A person enters the room. the mean age is now 33 so the age of the person 68 who entered the room.
In statistics, in addition to the mode and median, the mean is one of the measures of central tendency. Simply put, the mean is the average of the values in the given set. It indicates that values in a particular data set are distributed equally. The three most frequently employed measures of central tendency are the mean, median, and mode. The total values provided in a datasheet must be added, and the sum must be divided by the total number of values in order to determine the mean. When all of the values are organized in ascending order, the Median is the median value of the given data. While the number in the list that is repeated a maximum of times is the mode.
So According to the question, the Mean of 5 people in a room =26
When a person enters the room mean age becomes = 33
The sum of their age is = 5*6 =130
when other persons enter the room means the total person becomes =6
and the sum of their age after another person enters the room= [tex]x+130[/tex]
where x is the age of the other person entering the room.
so, mean = 33= (130+x)/6
then, 130+x=6*33
And,130+x=198
so,x=198-130 =68

If a person's speed doubles and all else remains the same, what will be the person's angular momentum
Answer:
The person's angular momentum will be double
Step-by-step explanation:
Let
Speed of person=v
Mass of person=m
Radius=r
Speed of person=2v
We have to find the person's angular momentum when the speed of person is double and all else remains same.
We know that
Angular moment ,L=mvr
Using the formula
Angular momentum of person when speed 2v
L'=m(2v)r
[tex]\frac{L'}{L}=\frac{m(2v)r}{mvr}=2[/tex]
[tex]L'=2L[/tex]
Hence, the angular moment of person will be double when the speed of person is double.
