Answer:1/4 hour remaining
Step-by-step explanation:
Presenter 1 - 1/3 hour
Presenter 2 - 1/6 hour
Presenter 3 - 1/4 hour
Convert to least common denominator of 12
4/12 + 2/12 + 3/12 = 9/12
12/12 - 9/12 = 3/12
Reduce 3/12 to get 1/4 hour remaining
Answer:
1.5 meters.
Step-by-step explanation:
The ladder is 4 meters.
It reaches the height of 3.7 meters on a wall.
This creates a right angled triangle of hypotenuse (4 meters) and height (3.7 meters).
We are to find the base length.
Applying the Pythagorean theorem;
a² + b² = c² , where a is the base length, b is the height length and c is the hypotenuse length.
∴ a² = c² - b² = 4² - 3.7² = 2.31
a (base length) = 
= 1.519868415 meters
To round off the answer to the nearest tenth of a meter;
Tenth of a meter = 
× 1 meter = 0.1 meters
So we're rounding off the answer to one decimal place.
I.e 1.519868415 meters = 1.5 meters (rounded off to the nearest tenth of a meter.
Answer:
209259
Step-by-step explanation:
45200 / 21.6 = 209259.259259
209259.259259 rounded to nearest whole number = 209259
Answer:
45600 pounds = 20683.8 kg to the nearest 10th.
Step-by-step explanation:
Consider the provided measurement
1 kg = 2.20462 pounds
1 pound = 0.453592 kg
Multiply both the sides by 45600.
1×45600 pound = 0.453592×45600 kg
45600 pound = 20683.812 kg
Now convert it to the nearest tenths as shown.
45600 pound = 20683.8 kg
Hence, 45600 pounds = 20683.8 kg to the nearest 10th.
Answer:
-44
Step-by-step explanation:
108 ÷ 9 x (-12) ÷ 6 - (100 ÷ 5)
= 108 ÷ 9 x (-12) ÷ 6 - (20)
= 12 x (-12) ÷ 6 - (20)
= -144÷ 6 - (20)
= -24 - (20)
= -44
