Answer:

0.4521

Step-by-step explanation:

Instead, you can simply multiply a number by 45.21 as a decimal to get the answer.

45.21 percent means 45.21 per hundred. Therefore, to get 45.21 as a decimal, all you have to do is divide 45.21 by 100 like so:

45.21 ÷ 100 = 0.4521

Shortcut: When you divide anything by 100, just move the decimal point two places to the left.

Normally, to calculate 45.21 percent, you would multiply a number by 45.21 percent and then you would take the product of that and divide it by 100 to get the answer.

Solve the system of equations and choose the correct ordered pair. 3x-2y=12 and 6x+3y=21
NemiM [27]

Answer:

Solution ( \frac{26}{7} ,  \frac{-3}{7})

Step-by-step explanation:

Given  :  3x - 2y = 12 and 6x + 3y = 21.

To find : Solve the system of equations and choose the correct ordered pair.

Solution : We have given

3x - 2y = 12 -------(1)

6x + 3y = 21-------(2)

Multiplying the equation(1) by 2 , it become.

6x - 4y = 24 .

Now subtract it from equation (2).

6x + 3y = 21

(-)6x - (+)4y = (-)24 .

____________

0 + 7y = -3.

On dividing both sides by 7.

y = \frac{-3}{7}.

Plug the y = \frac{-3}{7} in equation 2 .

 6x  + 3*\frac{-3}{7} = 21

6x + \frac{-9}{7}  = 21.

On multiplying both sides by 7

42x  -9 = 21 *7 .

42x  -9 = 147 .

On adding both sides by 9

42x = 147 + 9 .

42x = 156.

On dividing both sides by 42.

x = \frac{156}{42}.

x = \frac{26}{7}.

Therefore, Solution ( \frac{26}{7} ,  \frac{-3}{7})

How far can she travel in 4 hours 53 minutes?
Vadim26 [7]

Step-by-step explanation:

1 hour she travels = 19 km

60 min = 1 hr

53 min = 1/60 * 53 hr = 53/60 hr

Now,

1 hr = 19 km

4 + 53/60 hrs = 19 * ( 4 + 53/60) km

She travels 92.78 km in 4 hrs and 53 minutes.
