Answer:
The surface area of capsule is 235.5 mm².
Step-by-step explanation:
Given that,
Diameter = 5 mm
Total length = 15 mm
We need to calculate the radius of each hemisphere
Using formula of radius of hemisphere
We need to calculate the length of cylinder
Using formula of length
Length of cylinder = Total length of capsule-radius of left hemisphere- radius of right hemisphere
We need to calculate the surface area of capsule
Using formula of surface area of capsule
Put the value into the formula
Hence, The surface area of capsule is 235.5 mm².
Answer:
Answer 3 (1.89m - 3)
Step-by-step explanation:
Since we know that the price per song is $1.89, that is going to be the part of the equation that goes with the variable.
Since she has a 3 dollar credit, this will reduce the cost of whatever amount of songs she is buying by 3 dollars, which means the second part of the equation is -3. You have your answer, 1.89m - 3.
For this sys of equations, like all, we first have to solve for y or x in either equation
In this case, lets solve for y in the 2nd equation
-2x+3y=9
add 2x to both sides
3y=9+2x
divide 3 on both sides
y=2/3(x) + 3
now plug in y for the first equation
2x-5(2/3x)+3/11
simplify
-4/3(x) + 3=11
subtract 3 from both sides
-4/3x=8
multiply 3/4 on both sides
x= -6
now plug in x for either equation, lets do the first one again
2 (-6)-5y=11
-5y-12=11
add twelve to both sides
-5y=23
divide
y=-23/5
your final answer would be
x=-6, y=-23/5
