Answer:

So, d(4)=68. That means that after 4 hours, Joanna has cycled 68 miles.

Step-by-step explanation:

First, we need to find what d(4) equals. In this equation t=4, so to solve plugin 4 and simplify.  Therefore, the equation is d(4)=12(4)+20. Once you multiply and add you get d(4)=68; this answers the first question.

Then, the next two questions ask you to interpret this answer. To do that go back and read what each variable stands for. "t" is for the time Joanna has cycled. So, in the equation d(4), 4 hours have passed. Additionally, "d(4)" represents the number of miles she has ridden. This means since d(4)=68 she has cycled 68 miles.

Note that since I cannot see the options I guessed at the exact wording, but the answers should be similar to what I wrote.

3. In the expression 362 + 6, what will be the place value of the first digit of the quotient?
Hunter-Best [27]

Answer:

B. It will be the tens place because 6 is greater than 3.

Step-by-step explanation:

Since the question said "quotient," then I believe we have 362 ÷ 6 and not "362 + 6."

If we work on the quotient we have

60\frac{1}{3}

Obviously, the first digit in the quotient is 6 and it takes the place of tens.

Looking at the options, option B fits the most because 6 is actually greater than 3.

Therefore, the answer is option B, It will be the tens place because 6 is greater than 3.

If $x$ is the average of $13$, $-16$, and $6$ and if $y$ is the cube root of $8$, find $x^2 + y^3$. Please Help
Alekssandra [29.7K]

Answer:

If we have a set of N elements:

{x₁, x₂, ..., xₙ}

The mean value (also called the average value) Is calculated as:

Average = (x₁ + x₂ + ... + xₙ)/n

So if x is the average of 13, -16 and 6 ( a total of 3 values)

x will be equal to:

x = (13 + (-16) + 6)/3 = (19 - 16)/3 = 3/3 = 1

x = 1

And we know that:

y = ∛8

Remember that:

2*2 = 4

and

4*2 = 8

then

2*2*2 = 2^3 = 8

then ∛8 = 2.

So we have:

y = ∛8 = 2

Now we can replace these values in the equation:

x^2 + y^3

replacing:

x = 1

y = 2

we get:

1^2 + 2^3 = 1 + 8 = 9
