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.

What is the degree of the polynomial?
A. 0
B. 1
C. 3
D. 5
Answer:
D
Step-by-step explanation:
The degree of a polynomial is determined by the largest exponent of a term within the polynomial.
Given
7x³ + 4x - 5 + 8[tex]x^{5}[/tex]
The term with the largest exponent is 8[tex]x^{5}[/tex] with exponent 5
Thus the polynomial is of degree 5 → D
Jenna wants to build 8 birdhouses. She needs 2 3/5 square feet of plywood for each birdhouse. If the plywood costs $0.56 per square foot, how much will it cost Jenna to make her birdhouses?
Answer:
$11.76
Step-by-step explanation:
We first need to find the amount of plywood for all birdhouses.
2 3/5 * 8 = 104/5 or 20.8 or 20 4/5
Now we can solve the cost for all the birdhouses by multiplying the total amount of plywood needed by the price per square foot.
20.8 * 0.56 = $11.648 or estimated $11.65
Remember, the question might be different, so don't submit anything yet. If the people who sell the plywood only sell in integer numbers (meaning you can't buy 4/5 of a square foot of wood but can only by amounts with no fractions), then Jenna must buy 21 square feet of plywood and will have a little bit of wood left over. Now solve just like before.
21 * 0.56 = $11.76
Therefore the answer is $11.76 if she can only buy an integer amount of plywood or estimated $11.65. I think the best answer is 11.76.

The ratio of the measures of the three sides of a triangle is 1/4:1/3:1/6 and its perimeter is 31.4 centimetres find the length of the shortest side
Given:
The ratio of the measures of the three sides of a triangle is [tex]\dfrac{1}{4}:\dfrac{1}{3}:\dfrac{1}{6}[/tex].
Its perimeter is 31.4 centimeters
To find:
The shortest side of the triangle.
Solution:
Let the measures of the three sides of a triangle are [tex]\dfrac{1}{4}x,\dfrac{1}{3}x,\dfrac{1}{6}x[/tex] respectively (in cm).
Its perimeter is 31.4 centimeters.
[tex]\dfrac{1}{4}x+\dfrac{1}{3}x+\dfrac{1}{6}x=31.4[/tex]
[tex]\dfrac{3x+4x+2x}{12}=31.4[/tex]
[tex]\dfrac{9x}{12}=31.4[/tex]
[tex]\dfrac{3x}{4}=31.4[/tex]
On further simplification, we get
[tex]3x=4\times 31.4[/tex]
[tex]3x=125.6[/tex]
Divide both sides by 3.
[tex]x=\dfrac{125.6}{3}[/tex]
[tex]x=41.867[/tex]
Now, the sides of triangle are
[tex]\dfrac{1}{4}(41.867)=10.467[/tex]
[tex]\dfrac{1}{3}(41.867)=13.956[/tex]
[tex]\dfrac{1}{6}(41.867)=6.978[/tex]
Therefore, the length of the shortest side is 6.978 cm.
There are 20 marbles in a jar, 5 are purple, 6 are green, 4 are pink and 5 are blue. You randomly select one marble.
What is the probability that you will randomly select either a blue or purple marble?
Answer: 5/20 for blue and purple: Step-by-step explanation: it's a total of 20 marbles and 4 colors for each marbal so if i had to guess 5 for blue and purple is 10/20 when added but it says either that why i put 5 instead. If it's wrong answer I am very sorry i did not get it right.
Have a good day and i hope this help you with the question given above.

shine sold two tables at 9900 rupees each.he got 10% profit in one sale and 10% loss in the other.did the total sale result in a profit or loss? what percentage? please give me step by step explanation
the total sale was neither a profit nor loss , 0%
Step-by-step explanation:
1st table :
100%-> 9900
110%-> 10890
10890-9900=990(earned)
------------------------------------------
2nd table :
100%->9900
90%-> 8910
9900-8910=990(lost)
990-990=0
hence the total sale was neither a profit nor loss , 0%

A tree 16 feet tall casts a shadow which forms an angle of 40° with the ground. How long is the shadow to the nearest hundredth of a foot?
Answer:
x = 19.06 feet
Step-by-step explanation:
Given that,
The length of a tree, h = 16 feet
It casts a shadow which forms an angle of 40° with the ground.
We need to find the length of the shadow. We can find it using trigonometry such that x be the length of the shadow. So,
[tex]\tan\theta=\dfrac{h}{x}\\\\x=\dfrac{h}{\tan\theta}\\\\x=\dfrac{16}{\tan(40)}\\\\x=19.06\ \text{feet}[/tex]
So, the length of the shadow is 19.06 feet.

Suppose point A is located at (1, 3) on a coordinate plane. If AB is 10 and the x-coordinate of point B is 9, explain how to use the Distance Formula to find the y-coordinate of point B.
Answer:
y =9
Step-by-step explanation:
you know the distance is 10 and some of the x,y points. so start filling what you know into the distance formula
10= √((9-1)^2 + (y-3)^2 )
square both sides to get ride of the square root
100 = 64 + (y-3)^2
36 = (y-3)^2
6 = y-3
y = 9
double check by using 9 for Y and you'll see it works.
Solve the system of equations by substitution. Show your work in the sketch and write your answer as an ordered pair.
There are 2 sketches in case you need more room.
`-3x+y=-2`
`y=4x`
Let's solve your system by substitution.
−3x+y=−2;y=4x
Rewrite equations:
y=4x;−3x+y=−2
Step: Solvey=4xfor y:
y=4x
Step: Substitute4xforyin−3x+y=−2:
−3x+y=−2
−3x+4x=−2
x=−2(Simplify both sides of the equation)
Step: Substitute−2forxiny=4x:
y=4x
y=(4)(−2)
y=−8(Simplify both sides of the equation)
Answer:
x=−2 and y=−8

An older person is 4 years older than 7 times the age of a younger person. The sum of their ages is 44. Find their ages
Answer:
5 yr and 39 yr
Step-by-step explanation:
Let x = the age of the younger
then 7x + 4 = the age of the older
Now x + 7x + 4 = 44
8x + 4 = 44
8x = 40
x = 5
7x + 4 = 7(5) + 4 = 35 + 4 = 39
Check: 5 + 39 = 44

You kayak up a river at a rate of 36 feet every 30 seconds. You kayak 304 feet every 2 minutes on the way back down the river. How much farther do you kayak in 5 minutes on the way down the river than in 5 minutes on the way up the river?
Answer:
400 feet
Step-by-step explanation:
on way up you travel 35 ft in 30 sec or 144 ft in 120 sec (2 min)
on way down you travel 304 ft in 120 sec (2 min)
the distance traveled for 5 minutes at rate from way 'up' is 360 feet
the distance traveled for 5 minutes at rate from way 'down' is 760 feet
difference is 400 feet
