HELP!

Answer:

$b=40.01\ units$

Step-by-step explanation:

we know that

Applying the law of sines

$\frac{b}{sin(B)}=\frac{a}{sin(A)}$

$b=\frac{a}{sin(A)}(sin(B))$

we have

$a=25\ units$

$A=32.5\°$

Find the measure of angle B

Remember that the sum of the interior angles of a triangle must be equal to 180 degrees

$A+B+C=180\°$

substitute the given values

$32.5\°+B+26.8\°=180\°$

$B=180\°-59.3\°=120.7\°$

Find the length side b

$b=\frac{a}{sin(A)}(sin(B))$

substitute the values

$b=\frac{25}{sin(32.5\°)}(sin(120.7\°))$

$b=40.01\ units$

It should have 110 because she can only afford 66 and so 176 - 66 = 110 so it should be 110

Which statement BEST describes the relationship between whole numbers and natural numbers shown in the diagram?

NeX [460]

Answer:

The correct option is B.

Step-by-step explanation:

Consider the diagram below.

It is a Venn diagram.

The diagram shows that all the natural numbers are contained in the set of all the whole numbers.

This implies that all natural numbers are whole numbers.

Then the statement best describing the relationship between whole numbers and natural numbers is:

(B) The diagram shows that natural numbers are a subset of whole numbers, because all natural numbers are whole numbers.

Thus, the correct option is B.

solve the proportion (with work please) <img src="https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B5%7D%20%3D%5Cfrac%7Bn%7D%7B10%7D" id

valentina_108 [34]

Solution:

If $\frac{a}{b} = \frac{c}{d}$ then $ad=cb$ . You could use that to solve the proportion,

$\frac{10}{5}=\frac{n}{10} \\5n=10(10)\\5n=100\\\frac{5}{5}n=\frac{100}{5} \\n=20\\$

Answer:

$n=20$

Check:

$\frac{10}{5} =\frac{20}{10} \\2=2$
