The correct answer is: 44.1ft - 46ft = -1.9ft/44.1ft = .043% relative error. Please mark Brainliest if helpful
Find 28/70 and then mult. the result by 100%.
Using a calculator, 28/70 = 0.4. Multiplying this result by 100%, we get 40%.

Here we know that Margie is standing on a bridge looking at the river. She throws a rock over the bridge with an initial velocity of 60 ft/sec. The height, h, of the rock at the rime t seconds after it was thrown can be modeled by the equation:

To calculate how long will it take for the rock to reach the surface of the water, we need to set
. So:

Given that time can't be negative, we just choose the positive value. Therefore, <em>it will take 4.70 seconds for the rock to reach the surface water.</em>
Commonly the horizontal axis represent the x-axis. So, you need the point that means x = 3 (positive 3), so, it is the point A.
The volume of a cone is V= (1/3)pi r²h
it was given
h=12cm
radius=3cm
the volume of the first cone is V1= 1/3)pi r²h1
where h1= h/2=6cm
so its volume is V1=1/3)xpix3²x6=56.52cm^3
and since the two cones are identical so V1=V2=<span>56.52cm^3,
we need </span><span>56.52cm^3 or salt </span>
