Answer:
Step-by-step explanation:
Since the phone costs $7 for 3 minutes i.e $7=3minutes
$x = 1 minute
$7 = 3x
x = 7÷3
x = $2.33
Answer:
C
Step-by-step explanation:
This is the only possible correct answer because the other three all show the final price as 0.90x, which is correct since the price is the normal one minus 10 percent. C is incorrect because it suggests the normal price has a 10% tax, or extra value on it.
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)
5 is B
6 is H
6 is H because between -7 and -5 is the point (0,6) x being the zero. making the g(x) aka f(X) g(0) = 6. cherrs
