Erica had 6 coins in her coin collection. she goes to a coin show and buys some coins. how many dose she have now?

Anuta_ua [19.1K]

Since, it is not given how many coins did Erica buy at the coin show, so, we can suppose that Erica bought "n" coins from the coin show.

Now, we know that Erica already had 6 coins in her coin collection before she went to the coin show and bought the "n" coins.

Therefore, the total number of coins that Erica will have in her possession after buying "n" coins from the coin show will be 6+n.

What is the distance between Harry’s home and his office?

Svetach [21]

Answer:

The distance between Harry’s home and his office? is 15 miles.

Step-by-step explanation:

The speed, distance time formula is:

$Speed(s)=\frac{Distance(d)}{Time(t)}$

Given:

Speed (s) = 30 miles/hour

Then the relation between distance and time is:

$s=\frac{d}{t} \\30=\frac{d}{t}\\d=30t...(i)$

If Speed was 60 miles/hour the time taken is $(t-\frac{1}{4})$ hours.

Then the relation between distance and time is:

$s=\frac{d}{t} \\60=\frac{d}{(t-\frac{1}{4}) }\\d=60t-15...(ii)$

Use the value of d = 30t in (ii)

$d=60t-15\\30t=60t-15\\30t=15\\t=\frac{1}{2} hour$

Determine the distance as follows:

$d=30t\\=30\times\frac{1}{2} \\=15\ miles$

Thus, the distance between Harry’s home and his office? is 15 miles.

If the diameter of an entire coconut is 5 inches, and the coconut meat is 1 inch thick.

Arturiano [62]

Answer:

V=33.51in^3

Step-by-step explanation:

5inch-1 in

=4inch

divide by 2 because the problem gives diameter, not radius. (radius is half of diameter)

The space inside is a sphere so it will be

V=4/3πr^3

V=4/3*pi*(2)^3

V=33.51 inch cubed

Need help lol

We need to read the graph to see which are the two quantities related and how these are related.

The two quantities on the graph are:

Distance from Elena's house
Time.

Such that the distance from Elena's house is a function of the time.

<h3>How to read the graph?</h3>

We need to only read graph A, notice that she is coming back from school and going home, the graph starts at a high value and ends at zero. So we can assume that the vertical zero represents her home.

We know two events, first, she goes home and needs to come back to search for something, this is represented with the first "inverted peak" of graph A, then we have a constant line, that represents the time she is in the school looking something in her locker.

Then she goes home again, this time she finds a friend and goes to the library (this is why the line goes up again) and then she stops at the library for some time (this is why the line is horizontal for some time). Finally, she goes home, represented by the last segment of the line that intercepts the horizontal axis.

Then the two things represented in the graph are:

Distance from Elena's house (in the vertical axis) and time (in the horizontal axis).

This means that the distance from Elena's house is a function of time.

(The quantity in the vertical axis is a function of the quantity in the horizontal axis).
