To find Kevin's age, subtract 17 by 3 to find how old Kevin is, which is 7. Then, to find Uncle rob's age, add 17 plus 3 to get 20, then multiply that by 3 to see how old Uncle Rob will be, which is 60.Then, subtract 6 from 60 to get 54.The final answer is that Kevin is 7 years old, and Uncle Rob is 54 years old. Hope this helps!

Answer:

Today, Kevin is 7 years old, and Uncle Rob 54 is years old.

Step-by-step explanation:

Tonia will be 17 years old in 3 years,  so, to get Tonia´s age now, make 17-3. She is 14 years old today.

As Tonia twice the age of Kevin,  so,  Kevin´s age is the actual age of Tonia divided by 2. That will be 14/2=7

To get Uncle´s age ,  we start at 17 years of Tonia, We must added it 3 years,  so she will be 20 years old. Remember we have added 6 years from today.  

Then,  if uncles will be three times Tonia´s age, that will be =20*3=60.

Now,  6 years before,  he is 60-6 =54 years

Use complete sentences to describe the range of the sine function.
MA_775_DIABLO [31]
The Range of a function is the set of all values that that function can take.

Given the sine function f(x)=sinx,

This function is the function which calculates the sine of the values of x.

According to the definition of the sine of an angle x in the unit circle, 

-1 \leq sinx \leq 1,

so the sine of an angle is always larger or equal to -1, and smaller or equal to 1.

This means that the values that the sine function takes are any values between -1 and 1, inclusive.

This determines the Range of the sine function. 

So the Range of the sine function is [-1, 1]

Q. Fine Floors can install 15 square yards of carpeting in 4 hours and 30 minutes. At this rate, how
creativ13 [48]

It takes 5.22 hours to install carpeting in a room

Step-by-step explanation:

At first lets find the relation between yard, feet and inch

1. 1 yard = 3 feet

2. 1 foot = 12 inches

3. 1 yard = 36 inches

Let us change all measures to inches

∵ 1 yard = 36 inches

∴ 1 yard² = (36)² inches²

-  Fine Floors can install 15 square yards of carpeting in 4 hours and

  30 minutes

∵ 15 yard² = 15 × (36)² inches²

∴ 15 yards² = 19440 inches²

∵ 1 hour = 60 minutes

∴ 30 minutes = 30/60 = 0.5 hour

∴ 4 hours and 30 minutes = 4.5 hours

∴ Fine Floors can install 19440 inches² in 4.5 hours

∵ The dimensions of the room are 11 feet 9 inches by 13 feet 4 inches

∵ 1 foot = 12 inches

∴ 11 feet 9 inches = 11 × 12 + 9 = 141 inches

∴ 13 feet 4 inches = 13 × 12 + 4 = 160 inches

∴ The area of the room = 141 × 160 = 22560 inches²

Now lets use the ratio method to answer the question

⇒ area of carpeting (in²)      :      time of carpeting (hr)

⇒ 19440                                :      4.5

⇒ 22560                               :      h

By using cross multiplication

∴ 19440 h = 4.5 × 22560

∴ 19440 h = 101520

- Divide both sides by 19440

∴ h = 5.22 hrs

It takes 5.22 hours to install carpeting in a room
