Answers

Answer 1
Answer:

Answer:  The correct option is (D) 3 to 5.

Step-by-step explanation:  Given that a youth ice hockey game has 3 periods that are each 20 minutes long. Colin plays 12 minutes each period.

We are to select the correct ratio that shows Colin's playing time compared to the total number of minutes of playing time possible.

Since there are three periods, so Colin's total playing time is given by

T_p=12+12+12=36~\textup{minutes}.

And each period is 20 minutes long, so total number of minutes playing time possible will be

T=20+20+20=60~\textup{minutes}.

Therefore, the ratio that shows Colin's playing time compared to the total number of minutes of playing time possible is given by

T_p:T\n\n\n=(T_p)/(T)\n\n\n=(36)/(60)\n\n\n=(3)/(5)\n\n\n=3:5.

Thus, the required ratio is 3 to 5.

Option (D) is CORRECT.
Answer 2
Answer: 3*20=60

3*12=36

36:60=3:5
The answer is D. 3 to 5

Please help me A.S.Y.C.

Answers

we know that

The easiest way to find the number that makes the statement true is to substitute the given answers into the equation.

so

Part 1)

4.3-2x < x^(2) -2

a) For x=0

4.3-2*0 < 0^(2) -2

12 < -2 -----> is false

b) For x=1

4.3-2*1 < 1^(2) -2

10 < -1 -----> is false

c) For x=2

4.3-2*2 < 2^(2) -2

8 < 2 -----> is false

d) For x=3

4.3-2*3 < 3^(2) -2

6 < 7 -----> is true

therefore

the answer part 1) is the option D

x=3

Part 2)

6*7-5x+x^(2) \geq x^(3) +x^(2)

a) For x=5

6*7-5*5+5^(2) \geq 5^(3) +5^(2)

42 \geq 150 ----> is false

b) For x=6

6*7-5*6+6^(2) \geq 6^(3) +6^(2)

48 \geq 252 ----> is false

c) For x=4

6*7-5*4+4^(2) \geq 4^(3) +4^(2)

38 \geq 80 ----> is false

d) For x=3

6*7-5*3+3^(2) \geq 3^(3) +3^(2)

36 \geq 36 ----> is True

therefore

the answer Part 2) is the option D

x=3

Part 3)

we have

8*3-4x\ (\ )\ 7*(10-x)

For x=3

8*3-4*3\ (\ )\ 7*(10-3)

12\ (\ )\ 49

we know that

12 < 49

therefore

the answer Part 3)  is the option B

<

Part 4)

we have

9*4-2x\ (\ )\ 5*(11-x)

For x=8

9*4-2*8\ (\ )\ 5*(11-8)

20\ (\ )\ 15

we know that

20 > 15

therefore

the answer Part 4)  is the option B

>
9. 4- 2(8) = -12
    55-40 = 15 
so C is true
 8. B
