Answer:
7 x 8 x 3 = 56 x 3 = 56 + 56 +56 = 168
Step-by-step explanation:
9514 1404 393
Answer:
1000
Step-by-step explanation:
If the number of protesters per minute remains a constant, then you could write the proportion ...
p/12 = 177/2.1
Multiplying by 12 gives ...
p = 12(177/2.1) ≈ 1011.4
Here, minutes are given to 2 significant figures, and the initial count is given to 3 significant figures. The best you can hope for is that your estimate is good to 3 significant figures:
1010 protesters
It is probably sufficient to report the number to 2 significant figures*:
1000 protesters
_____
* Unfortunately, with a number like 1000, the only way you can tell it has 2 significant figures is to report it as 1.0×10³ or 10. hundreds. The trailing zeros are usually not considered significant.
Answer:
sec (x)
Step-by-step explanation:
sec (x) tan (x) cos (x) csc (x) =
We know sec = 1/ cos
Tan = sin/cos
csc = 1/sin
Replacing into the expression
1/ cos (x) * sin(x)/ cos (x) * cos (x) * 1 / sin(x)
Canceling like terms
1/ cos (x)
sec(x)
From diameter you get radius by halving the diamter
radius = 14/2 = 7 cm
volume, height, and radius of a cylinder are all related by formula for volume of cylinder:
V = <span>πr²h
If we want to solve for h, we divide both sides by </span><span>πr² and get
h = V/(</span><span>πr²)
since V = 112</span><span>π and r = 7, h is equal to
h = (112</span>π)/(<span>π*7²) = 112/49 = 16/7 cm
height is C 16/7 cm
</span>
Answer:
The answer is 4/9
Step-by-step explanation:
Hi. Here's the work.
First turn everything into an improper fraction.
÷ = ÷
To divide fractions we multiply by the flipped version of the fraction, or the reciprocal.
÷ =
Now we just multiply the fractions!
=
The answer is therefore 4/9. Please mark brainliest if possible and i hope you get a good grade on your homework. ;)
