Answer:
1. no
yes
yes
2. d¹/³ b is the final answer
Step-by-step explanation:
1. a surd is just an irrational number, so a radical or a never-ending decimal
2.
simplify like we did to the others by distributing the exponent through the parentheses, then combining like terms, and finally combining fractions.
b⁻⁵(cd⁻¹)³ → b⁻⁵c³d⁻³
d(bc²)⁻¹ → d b⁻¹c⁻²
<u> d⁻⁵b⁻⁸ </u> → <u>d⁻²b⁻³ </u> → d⁻²b⁻³c⁻³
b⁻⁵c³d⁻³ c³
<u />
<u>d b⁻¹c⁻² </u> → d b⁻⁴c⁻³
b³c
divide
<u> d⁻²b⁻³c⁻³</u> → d⁻³b
d b⁻⁴c⁻³
positive indices are just positive exponents; it wants you to make the exponents positive. to do that you find the reciprocal, so you turn the negative exponent into a fraction under the number one and get rid of the negative.
d¹/³b
Let x = number of miles, cost per mile = 82 cents = $0.82
Cost = 19.95 + 0.82*x
178.21 = 19.95 + 0.82x
0.82x + 19.95 = 178.21
0.82x = 178.21 - 19.95
0.82x = 158.26
x = 158.26/0.82
x = 193

Answer:
A
Step-by-step explanation:
Because energy takes up the same inside the box?
Answer:
C. d < 2
Step-by-step explanation:
Note that the dot is open, which means that it is not including the number 2 (as the dot is on 2), so you use either < or >. Now, note that the arrow is pointing towards the left, or <em>less than</em>. This means you will use < as your sign.
d < 2 is your answer

It would be less because 13/4 is equal to 78/24 or 3 6/24 and 3 5/6 is equal to 23/6 or 92/24. so in the end your equation would look like this: 3 6/24<3 20/24
