Answer:
61.4
Step-by-step explanation:
The length of two semicircles of diameter 10 is the circumference of a circle of that diameter:
C = πd = 10π ≈ 31.4
The perimeter includes that length plus the lengths of two straight sides that are 15 units each.
P = 31.4 + 2×15
P = 61.4 . . . . units
Answer:
The answer is 22.
Explanation:
Multiply -1 by -9.

Answer:
2
Step-by-step explanation:
I think :)
Answer:
B.The exponent of the solution is –12, the difference of the original exponents.
C.The coefficient of the solution must be greater than or equal to one but less than 10.
D.The quotient is 3.0 × ![10^{-12}](https://tex.z-dn.net/?f=10%5E%7B-12%7D)
Step-by-step explanation:
We are finding the quotient of the expression below in scientific notation
![\dfrac{9.6X10^{-8}}{3.2X10^4} \\=\dfrac{9.6}{3.2}X10^{-8-4}\\ =3 X 10^{-12}](https://tex.z-dn.net/?f=%5Cdfrac%7B9.6X10%5E%7B-8%7D%7D%7B3.2X10%5E4%7D%20%5C%5C%3D%5Cdfrac%7B9.6%7D%7B3.2%7DX10%5E%7B-8-4%7D%5C%5C%20%3D3%20X%2010%5E%7B-12%7D)
The following conclusions can be drawn
B.The power of 10 in the solution is –12, the difference of the original exponents.
C.The coefficient is 3, which is greater than or equal to one but less than 10.
D.The quotient is 3.0 × ![10^{-12}](https://tex.z-dn.net/?f=10%5E%7B-12%7D)
