Step-by-step explanation:the square root of 11 is 3.3 and that is less than 4

Answer:

<

Step-by-step explanation:

We can solve this easily by simply converting 4 to the root of its square. 4 squared is 16, and root 16 gives back 4 so the value remains the same.

[tex]4 = \sqrt{16 } \\ [/tex]

Now, we can compare the two values. As 11<16, the same will hold true for its square roots.

So your final answer would be <.

Derrick's Doggie Day Care charges a $12 registration fee plus $5 per hour for pet sitting. Pauline's Pooch Park charges $3 per hour plus an $18 registration fee. Which inequality below can be used to find the number of hours, h, for which the cost of Derrick's Doggie Day Care is at most the cost of Pauline's Pooch Park?

Answers

Answer:

the number of hours is >4

Step-by-step explanation:

given data

Derrick's Doggie

$12 registration fee plus $5 per hour for pet sitting.

the total charges for Derrick's Doggie  will be

y=12+5h---------------1

Pauline's Pooch Park charges $3 per hour plus an $18 registration fee.

the total charges for Derrick's Doggie  will be

y=18+3h---------------2

equating 1 and 2 we can solve for h which is the number of hours

12+5h=>18+3h

12-18=3h-5h

-8=-2h

h=8/2

h=>4

$36000. For every year after it is purchased, the car loses 17% of its value due to depreciation. What is the value of the car after 64 months? find in exponential function grade 11 math

Answers

Answer:

$13,320

Step-by-step explanation:

The expression for depreciation is

V=C(1-r)^t ,

where V is the value of the car after t years,

C is the original cost, and

r the rate of depreciation. If a car

given

C=$36000

r=17%= 0.17

t in years 64/12= 5.33years

Substituting to the formula we have

V=36000(1-0.17)^5.33

V=36000(0.83)^5.33

V=36000*0.370

V=13,320

the value will be $13,320

A pitcher in a major league baseball game threw 100 pitches. If 36 of the pitches were balls and 64 were strikes, what is the ratio of balls to strikes for that game?

Answers

Answer:

The ratio of balls to strikes is 9 : 16

Step-by-step explanation:

From the question, a pitcher in a baseball game threw a total of 100 pitches in which some were balls and others were strikes. 36 of them were balls and 64 were strikes.

To determine the ratio of balls to strikes for the game, we will divide the number of balls by the number of strikes.

That is,

Ratio of balls to strikes = Number of balls / Number of strikes

Number of balls = 36

Number of strikes = 64

Therefore,

Ratio of balls to strikes = 36 / 64

Ratio of balls to strikes = 9 / 16

Hence, the ratio of balls to strikes is 9 : 16.

Use the following information to complete parts I, II and III.
1 hour = 3,600 seconds
1 year = 31,556,952 seconds
Part I: Use scientific notation to estimate the number of hours in one year.
Part II: Use scientific notation to calculate the exact number of hours in one year.
Part III: In two or more complete sentences, compare your answers to parts I and II. In your comparison, discuss similarities and differences in your answers.

Answers

Answer:

Part I: Use scientific notation to estimate the number of hours in one year

Using the conversion factors

Estimate using scientific notation

31,556,952 seconds = 3.2 *  10^7

3600 seconds = 3.6 * 10 ^2

1 year = 3.2 *  10^7 seconds * 1 hour/ 3.6 * 10 ^2 seconds

3.2 /3.6 =.88888 (repeating)    

10^7 / 10^2 = 10^5

8.88888 * 10 ^5

8.888 * 10 ^4 hours

Part II: Use scientific notation to calculate the exact number of hours in one year.

31,556,952 seconds = 3.1556952 *  10^7

3600 seconds = 3.6 * 10 ^2

1 year = 3.1556952 *  10^7 seconds * 1 hour/ 3.6 * 10 ^2 seconds

3.1556952 /3.6 =.876582    

10^7 / 10^2 = 10^5

.876582 * 10 ^5      

8.76582*10^4 hours

Part III: In two or more complete sentences, compare your answers to parts I and II. In your comparison, discuss similarities and differences in your answers.

Part II is an exact answer, where Part I is an estimate.  Both Parts give values in the thousands of hours,  and are both  between 8700 and 8900 hours.  Part I can be done without a calculator where Part II is much harder to do without a calculator.

Lee's uncle is installing a new pool in his backyard. The pool is a square and has an area of 121ft^2. He decides to build a 4 ft wide deck to surround the pool. What is the outside perimeter of the deck? The small square is the pool and the deck is the big square

Answers

Answer: 76 feet

Step-by-step explanation:

Given: The pool is a square and has an area of [tex]121ft^2[/tex].

We know that , area = side²

side= √area

⇒ side= √121=11 feet

Width of deck  =4 feet

Length of deck around pool = 11+4+4 = 19 feet

Outside perimeter of deck = 4 (19) = 76 feet [since perimeter of square = 4 (side)]

Hence, Outside perimeter of deck = 76 feet
