Answer:

Charles practiced for the relay race for D. 9 hours last week.

Step-by-step explanation:

First, I would find the ratios the ratios for converting hurdle to javelin and javelin to relay.

Hurdle : Javelin ; 5 : 1.5

Javelin : Relay ; 2.5 : 5 or 1 : 2

Next, find the factors compared to the original numbers for hurdle to javelin.

15 / 5 = 3

To find the amount of javelin time they did, multiply 1.5 by the factor we got, 3.

1.5 * 3 = 4.5

Finally, double 4.5, since Charles does twice as much relay than he does javelin.

4.5 * 2 = 9 hours

How to do ratios like 2/6 because it is confusing how to do rates because I don't know how to do either

yanalaym [24]

The ratio is the relationship of two numbers. Here is an example, you have 2 apples and 6 bananas. To compare the ratio between the apples and the bananas we create a ratio, so the ratio would be 2 to 6, or 2:6, or 2/6.

A rate is a little different than the ratio, it is a special kind of ratio. That is a comparison of measurements that have different units, like pounds and quarters.

Assume that A ABC= A POR. Which of the following congruence statements are correct? Check all that apply. A. AB = OR B. BE PO C.

yulyashka [42]

For congruence of triangles.

If;

$\Delta ABC\cong\Delta PQR$

Then the corresponding sides and angles will be equal.

$\begin{gathered} AB=PQ \\ BC=QR \\ AC=PR \\ \measuredangle A=\measuredangle P \\ \measuredangle B=\measuredangle Q \\ \measuredangle C=\measuredangle R \end{gathered}$

Only the above congruence statements are true.

Any options that has any of the above congruence statement is true.
