Answer:

The number of words Tom typed are 144 and number of words Maria typed are 720 .

Step-by-step explanation:

As given

Tom and Maria typed in words in the ratio of 1 : 5 in 20 minutes.

They typed 864 words altogether.

Let us assume that the y be the scalar multiple of the Tom and Maria typed in words .

Number of words Tom typed = y

Number of words Maria typed = 5y

Thus the equation becomes

y + 5y = 864

6y = 864

y= \frac{864}{6}

y = 144

Number of words Tom typed = 144

Number of words Maria typed = 5 × 144

                                                  = 720

Therefore the number of words Tom typed are 144 and number of words Maria typed are 720 .

Answer:

As per the statement:

Tom and Maria typed in words in the ratio of 1 : 5 in 20 minutes.

Let x be the number.

Then;

Tom typed number of  words = x and

Maria typed number of words = 5x

It is also given that they altogether typed 864

⇒x+5x = 864

Combine like terms;

6x = 864

Divide both sides by 6 we get;

x = 144

then;

Number of words Tom typed = 144 and

Number of words Maria typed =5(144)=720

Therefore, number of words that Tom and Maria typed are: 144 and 720

Answer:

Step-by-step explanation:

y=0.860x17+3.302

foot is 17.992 inches long

Unfortunately, I don't have access to your data so i can't give a solid answer. However, I can tell you that if your coefficeint (number before x) is greater than 0.86, you have a greater rate of change. If its smaller, its a lower rate of change.
