The number is = 10x+y
if reverse the digits, the number is: 10y+x
The sum fo its digits is = x+y=5
I suggest this system of equations:
(10y+x)-(10x+y)=27 ⇒9y-9x=27
x+y=5
We can solve this system of equations by equaliztion method
x=5-y
9y-9(5-y)=27
9y-45+9y=27
18y=27+45
18y=72
y=72/18
y=4
x=5-y
x=5-4=1
The number is: 10x+y=10(1)+4=14
Answer: the number is 14
Answer: 10 meters
Explanation:
29 cm : blank meters
So how do we get from 348 cm to 29 cm?
To figure this out we divide.
348 divided by 28 = 12
we divided by 12 so we do the same with 120
120 divided by 12 = 10
So that’s the answer.
I hope this makes sense and helps you :)
F(x)=2(x-5)^2-24 simple algebra
Answer: First option is correct.
Explanation:
Since we have given that
Radius = 11 inches
Height = 14 inches
Now, according to question, we have mentioned that all the dimensions of the cylinder is to be quadrupled i.e. four times.
Then,
Radius is given by
Height is given by
As we know the formula for " Volume of cylinder ":
Hence, our volume of new similar cylinder is 340426.24 cubic in.
Therefore, First option is correct.
Volume of water in the glass = 3 x 2 x 4 = 24 cubic cm.
Volume of water plus the ring = 3 x 2 x 4.25 = 25.5 cubic cm.
Subtract the total with the ring from just the water:
25.5 - 24 = 1.5 cubic cm
