Maxine types 294 words in 7 minutes. How many words does Maxine type in 11 minutes?<br> 352 words
WINSTONCH [101]

Answer:

462 words

Step-by-step explanation:

Maxine types :

294 words ⇒ 7 minutes

Let the known number of words be x.

So,

294 words ⇒ 7 minutes

x words ⇒ 11 minutes

Therefore,

294 ⇒   7

x      ⇒   11

Now use cross multiplication and find the value of x.

7x = 294 × 11

7x = 3234

Now divide both sides by 7.

x = 462 words.

Hope this helps you :-)

Let me know if you have any other questions :-)

Answer:

88 inches

Step-by-step explanation:

The given bicycle has a tyre that is 28 inches in diameter.

How far the bicycle moves forward each time the wheel goes around is the circumference of the bicycle tyre.

This is calculated using the formula:

C =\pi \: d

We substitute the diameter and

\pi =  \frac{22}{7}

C =  \frac{22}{7}  \times 28

This simplifies to

C =22 \times 4

88 \: inches
