Add the fractions first, because both fractions have the same denominator ( bottom number) just add the numerators (top numbers) together and put it on top of the denominator:

1/3 + 1/3 = (1+1)/3 = 2/3

Now add the whole numbers:

2 + 3 = 5

The answer is 5 2/3

uranmaximum [27]

Since 2/3 is equal to 4/6, so you add 4/6 and 1/6 which equals 5/6 which is how much are <span>chocolate and cinnamon. Your leftover would be 1/6.</span>

Write each expression as an equivalent expression with a single logarithm. Assume xx, yy, and zz are positive real

Alekssandra [29.7K]

Answer:

$\ln(\frac{xx + yy}{zz})^{\frac{1}{2}}$

Step-by-step explanation:

Given:

1/2(ln(xx + yy) − ln(zz))

Now,

From the properties of log function,

1) n × ln(x) = ln(xⁿ)

and,

2) ln(A) - ln(B) = $\ln\frac{A}{B}$

applying the properties in the given equation

we get the above equation as:

$\frac{1}{2}(\ln\frac{xx + yy}{zz})$

( using the property 2 we get (ln(xx + yy) − ln(zz) = $\ln\frac{xx + yy}{zz}$

⇒ $\ln(\frac{xx + yy}{zz})^{\frac{1}{2}}$ ( using the property 1 i.e n × ln(x) = ln(xⁿ) )

expression as an equivalent expression with a single logarithm is $\ln(\frac{xx + yy}{zz})^{\frac{1}{2}}$

A six-sided number cube is rolled twice.

Marina CMI [18]

Answer: A and D

Step-by-step explanation:

Dependent events mean that one event depends on the outcome of the previous event.

A) If the first roll is a 3, and we want to sum more than 7 with the second roll, then the possible outcomes 5 and 6. Now if the first roll is 4, then the possible outcomes for the second event will be 4, 5 and 6. So you can see how the outcome space of the second event changes depending on the first event, so the events are dependent.

B) Here we do not have dependence, each event only depends on it's own outcome.

C) Again, both events only depend on it's own outcome, so the events are not dependent.

D) This is similar as the case for A, these events are dependent because is not the same if the outcome of the first event is 3, than if the outcome is 5 (the outcome needed for the second roll changes depending on the outcome of the first event)

E) Same as B and C, the events are independent.

Triple a number decreased by 14

Ira Lisetskai [31]

Since we know 14, but we don't know the other number, we use a variable. To do that, we look at the problem, then we figure out the unknown. The unknown is: A number. We know 14. Since "Triple" means 3, we can put the exponent 3 by X.

Therefore, the answer is $X^3-14$ .
