the volume of the composite figure is . Correct option D)
<u>Step-by-step explanation:</u>
Here we have , The figure is made up of a cylinder and a sphere which has been cut in half. The radius of each half sphere is 5 mm. We need to find What is the volume of the composite figure . Let's find out:
We know that Volume of figure is :
⇒ Volume of cylinder + Volume of hemi-sphere
⇒
⇒
Putting values of h= 10 mm , r = 5 mm( Not given in question ! Searched in correct question )
⇒
⇒
⇒
Therefore , the volume of the composite figure is . Correct option D)
Answer:
65 or 0.65 which are exactly the same area
Step-by-step explanation:
Notice that 65 is exactly the same as 0.65 .
The most likely answer is 65 , since 8 mm by 8 mm is a reasonable size for a square shaped key of a hand-held calculator to fit a human finger.
The answer 6.5 is an area too small (about a square 3 mm by 3 mm which is to small for a human finger. It would be more appropriate for a pen or point of some type.
Let's first define variables.
y: number of shares of $ 10
x: number of shares of $ 12
We write the system of equations:
10x + 12y = 210
y = 2x + 5
Solving the system:
x = 75/17
y = 235/17
Answer:
she has:
75/17 shares of $ 12
235/17 shares of $ 10
Answer:
B
Step-by-step explanation:
D is not the answer. The two binomials are added. That won't work.
C and A are not the answer C has a common factor in the first binomial
A has a 3 that is common in the second binomial.
B is completely factored. B is the answer.
