Answer is C.
3x and 4x² are not like terms, as their exponents do not share the same power (3x has a power of 1, 4x² has a power of 2)
Answer: 12
40% = 40/100 = 0.40
"of" means "multiply" in percent word problems like this. Multiply 0.40 with 30 to get 0.40*30 = 12
Optionally, you can solve the equation below for x
part/whole = percent/100
x/30 = 40/100
x/30 = 0.40
x = 0.40*30
x = 12
much of those steps follow a similar pattern to what was mentioned earlier.
Answer:
1 error / about 8 minutes and 30 seconds
Step-by-step explanation:
1/8.5 Divide the fraction by 7.
By dividing both numbers of the fraction, you are finding how many errors are in the number of minutes you make them.
Exact answer: 1/8.571428 repeated
Rounded answer: 1/8.56
Answer:
square root (50) = 7.071
Step-by-step explanation:
Using Pthagoras' theorem, the diagonal length is
.
Therefore, the diagonal length is the square root of 5^2+5^2,
= ![\sqrt{x} 25+25](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%2025%2B25)
= ![\sqrt{x} 50](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%2050)
= 7.071
