Answer:
1233.68 g
Step-by-step explanation:
Given:
The weights are
1.21 kg
546 mg
23.14 g
Here,
the units of all the weights given are not uniform, also the options are provided in grams
Therefore, we will first convert all the weights in the uniform unit i.e in grams
thus,
we have
1.21 kg = 1210 g
546 mg = 0.546 g
23.14 g
hence,
the total mass = 1210 g + 0.546 g + 23.14 g = 1233.686 ≈ 1233.68 g
Hence, the correct answer is option 4. 1233.68 g
Answer:
4
Step-by-step explanation:
The polynomial 3x^3 +4x^2 -8x -5 has 4 terms. A term is a product or single variable or constant separated from other terms by a plus or minus sign.
The four terms are ...
Step-by-step explanation:
short hand radius = 4
distance travellled in 1 day revolution = 2πr= 2 x 22/7 x 4= 25.1cm (approx)
distance travellled in 2 day revolution= 25.1+ 25.1 = 50.2
long hand radius= 6
each hour 1 revolution by long hand so in 24 hr 24 revolutions and 48 he 48 revolution
distance travelled in 1 hr = 2πr= 2 x 22/7 x 6= 37.7
distance in 48hr = 37.7 x 48= 1809.6 (approx)
so sum of both= 1809.6 + 50.2 = 1859.8
Answer:
x=5, y=4. (5, 4).
Step-by-step explanation:
2x-3y=-2
4x+y=24
------------------
-2(2x-3y)=-2(-2)
4x+y=24
----------------------
-4x+6y=4
4x+y=24
--------------
7y=28
y=28/7
y=4
4x+4=24
4x=24-4
4x=20
x=20/4
x=5
