If you can solve 20 multiplication facts in one minute then you could solve 50 multiplication facts in 3 minutes

1 minute = 20 facts

2 minutes = 40 facts

3 minutes = 60 facts

We can check our work by doing the unit rate:

60 facts ÷  3

____________     <--- fraction bar

3 minutes ÷  3

= 20 facts

__________ (20 facts per minute)

 1 minute

Answer:

150s or 2 min and 30 s

Step-by-step explanation:

20 facts = 1 min

10 facts = 30s

50 facts = ? min

50 / 10 = 5

30 * 5 = 150s

150s = 2 min and 30 s

The label on the car's antifreeze container claims to protect the car between −30°C and 130°C. To covert Celsius temperature to
jonny [76]

Answer:

-22°F < x < 266°F.

Step-by-step explanation:

The question states the incorrect formula to convert the Celsius temperature (C) into the Fahrenheit temperature (F). The correct one is given by:

F = 9C/5 + 32.

The given temperature inequality in Celsius is:

-30°C < x < 130°C; where x is any number that satisfies the inequality.

To convert it into Fahrenheit, simply plug in the values in the above formula.

Lower Limit:

F = 9(-30)/5 + 32.

F = -54 + 32.

F = -22°F.

Upper Limit:

F = 9(130)/5 + 32.

F = 234 + 32.

F = 266°F.

Therefore, the inequality will be -22°F < x < 266°F!!!

olasank [31]

Answer:

Conjecture :  2xy / ( x + y ) ≤  √xy

Step-by-step explanation:

Harmonic mean of  x and y = 2xy/( x + y )

<u>Formulate a conjecture about their relative sizes </u>

we will achieve this by computing harmonic and geometric means

Geometric mean = √xy

harmonic mean = 2xy/( x + y )

Conjecture :  2xy / ( x + y ) ≤  √xy

attached below is the proof
