Answer:
V ≈ 68.63 cm³
Step-by-step explanation:
the volume (V) of a sphere is calculated as
V = 
πr³
the volume of a hemisphere is half the volume of a sphere, so
V = 
× πr³ = 
πr³ , then
V = π × 3.2³
= π × 32.768
≈ 68.63 cm³ ( to 2 dec. places )
Answer:
Chris earned $ 43,344 each year
Monthly Chris earns $ 3,612
Step-by-step explanation:
If you earn a fixed amount of money each month, for 2 years and one year you have 12 months, then 2 years equals 24 months.
To know how much you earn each month we divide the total amount earned in the two years between 24 months
I = $ 86,688 / 24
I = $ 3,612
Monthly Chris earns $ 3,612
To calculate what he earned each year we divided $ 86,688 / 2
I = $ 86,688 / 2
I = $ 43,344
Chris earned $ 43,344 each year
Answer:
720
Step-by-step explanation:
because 8% of 9000$ is 720$.
another way.
Step 1: Our output value is 9000.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$9000=100$.
Step 4: Similarly, $x=.8%$.
Step 5: This results in a pair of simple equations:
$9000=100%(1)$.
$x=.8%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
Step 7: Again, the reciprocal of both sides gives
Therefore, 8%of $9000$ is $720
Given that loan amount P=20000
Interest rate r=5% = 0.05
Time of loan t=4 years
Now to find the interest amount we just plug those values into formula
simple interest = P × r × t
simple interest = 20000* 0.05* 4
simple interest = 1000 * 4
simple interest = 4000
Hence final answer is choice b. $4000.
