. Fiona has 18 red carnations, 27 white carnations, and 36 blue carnations. She wants to make arrangements of red, white, and blue carnations.She plans to use all of the flowers and to have the same number of each color in each arrangement. If she makes the greatest number of arrangements possible, then how many blue carnations will be in each arrangement?
Answers
Answer:
9 blue carnations.
Step-by-step explanation:
Given that,
Fiona has 18 red carnations, 27 white carnations, and 36 blue carnations. She wants to make arrangements of red, white, and blue carnations.
If she makes the greatest number of arrangements possible, then we need to find how many blue carnations will be in each arrangement.
Greatest possible arrangements = HCF of 18,27 and 36
The factors of 18 are: 1, 2, 3, 4, 6, 9, 12, 18,
The factors of 27 are: 1, 3,9,27
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
The greatest common factor = 9
For blue carnation,
B = (36/9) = 4
Hence, in each arrangements there are 9 blue carnations.

A 400 kg box and a 200 kg are to pushed across a horizontal table, the exact same distance with the exact force. Which box will have the most work done on it? Which box will get to the end first? Explain both of your responses.
Answers
Answer:
Both boxes have the same amount of work applied to them. The smaller box will get to the end first.
Step-by-step explanation:
For the 400 kg box, we can say,
force = 1 newton
force = mass*acceleration
1 = 400*acceleration
acceleration = 1/400 meters per second^2
acceleration = 0.0025 meters per second^2
Each second, the larger box's velocity is increasing by 0.0025 meters per second.
While the smaller box would have an acceleration of...
force = 1 newton
force = mass*acceleration
1 = 200*acceleration
acceleration = 1/200 meters per second^2
acceleration = 0.005 meters per second^2
Which is twice as much as the larger box.
Put simply: if the force applied is the same for the two boxes, then the smaller box will have larger acceleration. This is because more force is needed to push on the larger mass.
Because the smaller box has more acceleration, it will naturally travel faster compared to the larger box. Therefore, the smaller box reaches the goal line faster.
The sum of two numbers is less than 2. If we subtract the second number from the first, the difference is greater than 1. What are the two numbers?
Answers
Answer:
the value of these two numbers are 1/2 and 3/2
Step-by-step explanation:
Given that:
x+y < 2 ---- (1)
y - x > 1 ---- (2)
From equation (2), let y > 1 + x then substitute it into equation (1)
x + 1 + x < 2
2x + 1 < 2
2x < 2 - 1
2x < 1
x < 1/2
From equation (2), replace the value of x to be 1/2
y - 1/2 > 1
y > 1 + 1/2
y > 3/2
In 2011, a professional climber scaled the outside of Burj Khalifa making it all the way to 828 meters in 6 hours. how far did they climb in the first 2 hours?
Answers
Given:
Professional climbers climb 828 meters in 6 hours.
To find:
how far did they climb in the first 2 hours?
Solution:
According to the question,
In 6 hours, they climb 828 meters.
In 1 hour, they climb [tex]\dfrac{828}{6}[/tex] meters.
In 2 hour, they climb [tex]2\times \dfrac{828}{6}[/tex] meters.
Now, the distance they climb in the first 2 hours is
[tex]\text{Climb in first two hours}=2\times \dfrac{828}{6}[/tex]
[tex]=\dfrac{828}{3}[/tex]
[tex]=276[/tex]
Therefore, they will climb 276 meters in first 2 hours.

Solve for Angle DFE and Angle EDS in the diagram below:
Answers
Answer:
DFE = 23
EDS = 111
Step-by-step explanation:
Mathematically;
(3x-10) + 46 + 180 - (5x + 14) = 180
Reason for this is that sum of angles in a triangle is 180
Thus;
3x-10 + 46 - 5x-14 = 0
-2x + 22 = 0
2x = 22
x = 22/2 = 11
DFE = 3x - 10 = 3(11) - 10 = 33-10 = 23
EDS = 180 - (5x + 14) (sum of angles on a straight line)
180 - (5(11) + 14)
= 180 - 69
= 111
EDS
