Biconditionals are statements that work both ways.

Some examples:

If it rains, I go out, and if I go out, it must be raining.

This can be stated concisely in mathematical terms as

I go out IF AND ONLY IF it rains.

So looking at the given statements, only the last two work both ways, namely:

If the sun rises in the east, then it is morning, and if it is morning, the sun rises in the east.

Michael threw for 1,654 yards in his first five games. At this rate, how many yards will he have thrown for in fifteen games? ✗

vodka [1.7K]

Answer:

4,962 yards.

Step-by-step explanation:

We are given that,

For the first 5 games, Michael threw 1,654 yards.

Since, we see that, the relationship between the yards and the games are directly proportional.

Then for 15 games,

Michael will have thrown for $\frac{1654}{5}\times 3$ yards i.e. 1654 × 3 = 4,962 yards

Hence, for 15 games, Michael have thrown for 4,962 yards

Colt1911 [192]

Answer:

$3.90 was the cost of salami per kilogram.

Step-by-step explanation:

The question is incomplete, so the complete question is below:

$Hailey\ paid\ \$13\ for\ 1\ 3/7\ kg\ of\ sliced\ salami.\ \\What\ was\ the\ cost\ per\ kilogram\ of\ salami?$

Now, to find the cost of salami per kilogram.

Cost of $1\frac{3}{7}$ kilogram of sliced salami = $13.

Now, to get the cost of salami per kilogram we use unitary method:

If, the cost of $\frac{10}{3}$ kilogram of salami = $13.

Then, the cost of 1 kilogram of salami = $\frac{13}{\frac{10}{3}}$

$=\frac{13}{10}\times 3$

$=\frac{39}{10}$

$=\$3.90.$

Therefore, $3.90 was the cost of salami per kilogram.
