Hi there!
Let's use the formula of a sphere and divide it by two (for each hemisphere) to find the volume. Then, we'll create a ratio to figure out how many times larger the larger hemisphere is.
WORK:
Larger hemisphere:
V = 2/3(pi)(8^3)
V = 2/3(512pi)
V = 341.33pi
Smaller hemisphere:
V = 2/3(pi)(4^3)
V = 2/3(64pi)
V = 42.66pi
Ratio:
341.33/42.66
Approximately 4 times
ANSWER:
The larger hemisphere is approximately 4 times bigger than the smaller hemisphere
Answer:
5840 Hours
Step-by-step explanation:
Alrighty! So we know that an elephant eats 16 hours a day. What we are trying to figure out is How many hours in a year. So, we know that there are 365 days in a year. So, to figure this out, you will have to <u>multiply</u> 365 (days in a year) by 16 (hours). The answer should be 5,840.
Hope this helps! ^-^
Answer:
likely
because there are 12 blue marbles more then others
A hamburger costs $2.5 and a milkshake costs $1.75
Step-by-step explanation:
- Step 1: Form equations from the given details. Let cost of 1 hamburger be H and cost of 1 milkshake be M.
4H + 2M = 13.50 ------ (1)
& 3H + 1M = 9.25 ------ (2)
- Step 2: Multiply eq(2) with 2 to make coefficients of M equal.
6H + 2M = 18.50 ------- (3)
- Step 3: Subtract eq(3) from eq(1)
⇒ - 2H = - 5
⇒ H = $2.5
- Step 4: Substitute value of H in eq(2) to find M.
⇒ 3 × 2.5 + M = 9.25
⇒ 7.5 + M = 9.25
⇒ M = $1.75
