Answer:
-2/5 would be 2 down and 5 right
Answer:
d=60t
Step-by-step explanation:
Use the equation speed = distance / time
To get distance you do speed X time
D =60t shows that
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
For blue marbles:
16 = 8 * 2 ( 8 groups with 2 marbles in everyone of them )
For white marbles:
8 = 4 * 2 ( 4 groups with 2 )
8 + 4 = 12
Answer:
The greatest number of groups Colton can make is 12.
Answer:
Step-by-step explanation:
The formula for this is
where
N is the amount of the element left after a certain amount of time (for us it is measured in days),
N₀ is the initial amount of the element in grams,
t is the number of days gone by, and
H is the half life of the element. Filling in:
which simplifies a bit to
and a bit more to
N = 42(.25) which gives us a remaining amount of
N = 10.5
