The sum of three numbers is 15. The sum of the first number and three times the second number is 15. The sum of the second number and
the third number is 8. What are the three numbers?
Answer:
Im not sure if this is correct
x=7
y=8/3
z=16/3
Step-by-step explanation:
The three equations are
x+y+z=15
x+3y=15
y+z=8
you can use substitution for the first and third equation so it would be
x+8=15
x=7
then use sub for the second equation
7+3y=15
3y=8
y=8/3
and you can finish by using sub for the third equation
8/3+z=8
3z=16
z=16/3

If six pieces come off of a hot press, find the probability that two are Grade A, three are Grade B, and one is a Cull.
Step-by-step explanation:
Given data:
No of pieces = 6
Grade A = 2
Grade B = 3
Cull = 1.
Solution:
Probability that two are Grade A
P = 2/6
= 0.33
Probability that 3 are Grade B
P = 3/6
= 0.5
Probability that 1 is a cull
P = 1/6
= 0.17

The length of Amy's rectangular kitchen is 12 feet. If the area of the room is at least 96 square feet, what is the smallest width the room could have? Show your work
Answer:
8 feet is the shortest possible with the room could have
Step-by-step explanation:
12×8=96
Answer:
8 is the smallest width the room could be
Step-by-step explanation:
s represents the number that is the smallest the room could be
12s = 96
divide both sides by 12
12s/12 = 96/12
s = 8
Jonathan’s parents told him that for every five hours of homework or reading he completes, he would be able to play three hours of video games. His friend Lucas’ parents told their son that he could play 30 minutes for every hour of homework or reading he completes. If both boys spend the same amount of time on homework and reading this week, which boy gets more time playing video games? How do you know?
Answer:
So, to set up this equation, lets just say that Lucas did 5 hours of homework also. The ratio of Lucas's homework to video games is 60 minutes of homework/30 minutes of video games. If we converted the 5 hours into 300 minutes then you would multiply the 60 minutes by 5 and the 30 minutes by 5 also. You would get 300 minutes/150 minutes. Jonathan's ratio is every 5 hours of homework/3 hours of video games. We would convert this to minutes by taking both numbers and multiplying them by 60. We would get 300 minutes/180 minutes. Using this we know that Jonathan gets more time to play video games because every 5 hours of homework he gets 180 minutes of gaming and for Lucas, every 5 hours of homework he only gets 150 minutes of gaming. I hope that this helped you!

(c) Archimedes was particularly pleased when he determined the ratio of the volumes of a sphere and cylinder. Determine the ratio of the volume of a sphere to the volume of a cylinder having the same radius, and having height the same as the diameter of the sphere:
The volume of the sphere and the volume of the cylinder can be
expressed in terms of their radius.
Correct response:
The ratio of the volume of the sphere to the volume of the cylinder is 2 : 3Methods by which the ratio of the volumes is calculatedThe given parameters are;
Radius of the sphere = Radius of the cylinder
Height of the cylinder = Diameter of the sphere
Required:
The ratio of the volume of a sphere to the volume of a cylinder.
Solution:
Let r represent the radius of the sphere, we have;
The diameter of the sphere, D = 2·r
Therefore, the height of the cylinder, h = D = 2·r
The volume of the cylinder is; [tex]V_{cylinder}[/tex] = π·r²·h
[tex]\mathrm{The \ volume \ of \ a \ sphere\ is} \ V_{sphere} = \mathbf{ \dfrac{4}{3} \cdot \pi \cdot r^3}[/tex]
Therefore;
[tex]\mathbf{\dfrac{V_{sphere}}{V_{cylinder}}} = \dfrac{\dfrac{4}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 \cdot h} = \dfrac{\dfrac{4}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 \times 2 \cdot r} = \dfrac{\dfrac{4}{3} }{2} =\dfrac{4}{6} = \dfrac{2}{3}[/tex]
[tex]\dfrac{2}{3} \ expressed as \ a \ ratio \ is \ 2:3[/tex]
The ratio of the volume of a sphere to the volume of a cylinder having the same radius, and having a height the same as the diameter of the sphere is 2:3Learn more about the volumes of solids here:

What’s the unit rate
Hi friend! Hope this helps!
When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
