A foot is 12 inches long. If an inch is about 2.54 centimeters long, how many centimeters are in a foot?

Answers

Answer 1

Answer: This is a question that needs understanding. The calculation part is comparatively easy. We should first concentrate and write down all the important information's that are given in the question.
1 foot = 12 inches
1 inch = 2.54 centimeters
The thing that needs to be determined is
1 foot = ? centimeters
Now
1 foot = 12 inches
= (12 * 2.54) centimeters
= 30.48 centimeters
So from the above deduction we can clearly see that 1 foot is equal to 30.48 centimeters. I hope the procedure is simple enough for you to understand.

Answer 2

Answer:

Answer: 30.48

Step-by-step explanation: There are 2.54 centimeters in an inch so of you multiply that by 12 you get 30.48

100πcm².

None of the options is correct

Step-by-step explanation:

Total surface area of a cone $S$ = $\pi r^(2)+\pi rl\n$

Since the diagram is half of a cone, its surface area will be $S = (\pi r^(2) +\pi rl)/(2)$

r = radius of the cone

l = slant height

From the diagram diameter of the cone = 16m;

r = 16/2 = 8m

l = 17m

$S = (\pi (8)^(2) +\pi (8)(17))/(2)\nS = (64\pi + 136\pi )/(2) \nS = 32\pi + 68\pi \nS = 100\pi cm^(2)$

Which kind of function best models the data in the table? Use differences or ratios.y X
0 1.7
1 6.8
2 27.2
3 108.8
4 435.2

a. linear
b. quadratic
c. exponential
d. none of the above

Answers

Answer:

Option C exponential.

Step-by-step explanation:

To find the function best models the data in the table we will find the common ratio first. If the common ratios of the function are same then it's an exponential function.

For x = 0 and x = 1

$(f(1))/(f(0))=(6.8)/(1.7)=4$

For x = 1 and x = 2

$(f(2))/(f(1))=(27.2)/(6.8)=4$

For x = 2 and x = 3

$(f(3))/(f(2))=(108.8)/(27.2)=4$

Now we are sure that it's an exponential function.

For linear function common difference should be same in each term.

f(1) - f(0) = 6.8 - 1.7 = 5.1

f(2) - f(1) = 27.2 - 6.8 = 20.4

Therefore it's neither a linear function nor quadratic function.

Option C. is the correct option.

THE ANSWER IS LETTER C

What is the simplified form of the equation fraction 4 over 5 n minus fraction 1 over 5 equals fraction 2 over 5 n?n = −2
n = 4
n = fraction 1 over 2
n = fraction 2 over 3

Answers

Answer: The correct option is

(C) n = fraction 1 over 2.

Step-by-step explanation: We are to find the simplified form of the fraction 4 over 5 n minus fraction 1 over 5 equals fraction 2 over 5 n.

From the given information, we can write the equation as follows:

$(4)/(5)n-(1)/(5)=(2)/(5)n.$

Solving the above equation, we get

$(4)/(5)n-(1)/(5)=(2)/(5)n\n\n\n\Rightarrow (4)/(5)n-(2)/(5)n=(1)/(5)\n\n\n\Rightarrow (4-2)/(5)n=(1)/(5)\n\n\n\Rightarrow (2)/(5)n=(1)/(5)\n\n\n\Rightarrow n=(5)/(2* 5)\n\n\n\Rightarrow n=(1)/(2).$
