What is the triangles' perimeter

Mathematics
2 answers:
DENIUS [597]2 years ago
6 0
To find the perimeter of any shape, you find the sum of their side lengths.

In this case, this triangle has side lengths of 1.197, 0.764, and 1.74.
Add these, and the sum is your answer.

1.197 + 0.764 + 1.74 = 3.701

Therefore 3.701 is the correct answer :)

If there is a zero in the hundredths place, A, B, and C cannot be correct, as they have a one, seven, and seven in the hundredths place.  Thus, D is the answer, as it has a zero in the hundredths place.

Use differentials to estimate the amount of paint needed to apply a coat of paint 0.07 cm thick to a hemispherical dome with dia
Mademuasel [1]

An hemispherical dome is half a sphere. If the diameter is 60 m, then the radius is 30 m.

We can use differentials to solve this problem because we are adding a thin layer to the original dome, so the volume of the dome in increased by a differential of itself.

This differential volume that the dome is increased is equal to the volume of the coat of paint.

The volume of the dome can be written as:

\begin{gathered} V=\frac{4\pi}{3}r^3 \\ \frac{dV}{dr}=\frac{4\pi}{3}\cdot3r^2\Rightarrow dV=\frac{4\pi}{3}\cdot3r^2\cdot dr=4\pi r^2\cdot dr \end{gathered}

Now, we can calculate dV as:

\begin{gathered} dV=4\pi r^2\cdot dr \\ dV\approx4\cdot3.14\cdot(30m)^2\cdot0.07\operatorname{cm}\cdot\frac{1m}{100\operatorname{cm}} \\ dV\approx12.57\cdot900m^2\cdot0.0007m \\ dV\approx7.92m^3 \end{gathered}

Answer: the paint needed for this coat is approximately 7.92 m^3

Which number produces an irrational number when added to 3/4?
S_A_V [24]
Any irrational number produces an irrational number when added to 3/4.

This is because 3/4 is rational (it can be represented as a ratio of two integers). You can get an irrational number only when you add rational to irrational (because rational to rational produces a rational sum).
