Answer 1
Answer:

Answer:

10 1/2

Step-by-step explanation:

white : red

2 : 3

1 : 3/ 2

7 : 3/2 ×7

7 : 10.5

7 : 10 1/2

option 3 is the answer
Answer 2
Answer:

Greetings from Brasil...

Let's apply rule of 3....

   WP              RP

    3    --------    2

    7    --------    X

3 · X = 7 · 2

3X = 14

X = 14/3

remember that

14/3 = 4 2/3

So, 7 WP = 4 2/3 RP

Round all the way 2689

Answers

2689

rounded to the nearest tens = 2690
rounded to the nearest hundreds = 2700
rounded to the nearest thousands = 3000

If the number before the place it needs to be round off is 5 and above, then it is rounded up. If the number is 4 and below, it is rounded down.

For example: 
2444 

rounded to the nearest tens = 2440
rounded to the nearest hundreds = 2400
rounded to the nearest thousands = 2000

Step-by-step explanation:

Y varies directly with X and has a constant rate of change of 6. When the value of Y is 11, then the value of X could be _____.equal to zero
less than 2
equal to 6
greater than 11

Answers

Answer:  The correct option is (B) less than 2.

Step-by-step explanation:  Given that Y varies directly with X and has a constant rate of change of 6.

We are to find the possible value of X when the value of Y is 11.

Since Y varies directly with X, so we can write

Y\propto X\n\n\Rightarrow Y=kx~~~~~~~~~~~~~~~(i),~~~~~~~~~\textup{[where 'k' is the constant of variation]}

Since the rate of change is constant and is equal to 6, so we must have

k=6.

So, from equation (i), we have

Y=kX\n\n\Rightarrow Y=6X~~~~~~~~~~~~~~~~~~~~~~(ii)

Now, when Y = 11, then from equation (ii), we get

Y=6X\n\n\Rightarrow 11=6X\n\n\Rightarrow X=(11)/(6)<(12)/(6)=2\n\n\n\Rightarrow X<2.

Thus, the value of X is less than 2 when Y = 11.

Option (B) is CORRECT.
