We need to find the fewest number of significant figures in the given options.

A. 360.01 has five significant figures.

B. 5,003.1 has five significant figures.

C. 296.54 has five significant figures.

D. 18.3 has only three significant figures.

Therefore, the fewest number of significant figures are 3.

<h3>Therefore, correct option is D option.</h3><h3>D. 18.3.</h3>

Answer:

$B = 325$

Step-by-step explanation:

Given

Total = 900

Singing = 600

Dancing = 500

None = 125

Required

Determine the number of students that participate in both

Representing; Singing with S, Dancing with D, Both singing and dancing with B and None with N;

In Set Notation;

$Total = (S - B) + (D - B) + N + B$

Substitute 900 for Total, 600 for S, 500 for D and 125 for N

$900 = (600 - B) + (500 - B) + 125$

Open Brackets

$900 = 600 - B + 500 - B + 125 + B$

Collect Like Terms

$900 = 600 + 500 + 125 - B - B + B$

$900 = 1225- B - B + B$

$900 = 1225- B$

Collect Like Terms

$900 - 1225 = -B$

$-325 = -B$

Multiply both sides by -1

$-1 * -325 = -B * -1$

$325 = B$

Reorder

$B = 325$

<em>Hence, the number of students that do not participate in both is 325</em>

For this case we will define the following:
A, B: are the values of the triangle angles
a, b: are the values of the lengths of the sides opposite the angles A, B.
We then have to use the law of the sine:
$\frac{sinB}{b} = \frac{sinA}{a}$
Clearing the angle B we have:
$sinB = \frac{sinA}{a}*b$
$B = arcsin(\frac{sinA}{a}*b)$
Substituting values we have:
$B = arcsin(\frac{sin113}{200}*134)$
$B = 38.08$
Answer:
the following is true:
A. angle B=38.08 degrees
