Answer:
Given:
Radius of large sphere: R1
Volume of sphere: V1
Radius of small sphere: R2
Volume of sphere: V2
R1=2R2
We know that:
Volume of a sphere: 4/3πR^3
Volume of large sphere: 4/3πR1^3
Now we know that R1=2R2(given)
Thus volume of large sphere(V1) 32/3πR2^3.
Volume of small sphere(V2): 4/3πR2^3.
Ratio of volume of large sphere to small sphere is 8:1.

Answer:
Let the price of one senior citizen ticket be <em>sc</em> and the price of one student ticket be <em>st</em>.
Let's write equations using the information given and the variables above:
=> 5sc + 15st = $137.50
=> 20sc + 44st = $430
Hmm.. We can multiply 5sc by 4 to get 20sc.
=> 4(5sc) + 4(15st) = 4($137.50)
=> 20sc + 60st = $550
Now we can subtract the second equation from the first to determine the price of a student ticket.
20sc + 60st = $550
- 20sc + 44st = $430
=> 16st = $120
=> st = $7.5
So, the price of a student ticket is $7.5.
Answer:
Is there an error in the question? it has BC = 27 twice and we don't know much about the other sides. Anyway let's try
Step-by-step explanation:
You are told that to go from WXYZ to ABCD the scale factor is 2/3, which means that you multiply by 2/3. So to go the other way round, from ABCD to WXYZ which is what you want, you divide by 2/3, or multiply by 3/2.
So, to find XY you multiply the right side from ABCD by 3/2. I think BC is the right side?
So XY = 27 × 3/2
XY = 81 / 2 or 40.5 or 40 1/2
