Find all the missing elements:

pshichka [43]

Answer:

C = 21.78 and a= 8.88

Step-by-step explanation:

Here, sides b=7 and c=3

Also, Angle B=60

Angle B is between side c and a

It can be solve by cosine rule and sin rule

sin rule says,

$\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC} \\ \frac{a}{sinA} = \frac{7}{sin60} = \frac{3}{sinC} \\ \frac{7}{sin60} = \frac{3}{sinC} \\ sinC = \frac{3}{7} \: sin60 = 0.3711537445 \\ \\ C = 21.78$

cosine rule says,

${a}^{2} = {b}^{2} + {c}^{2} + 2bc \: cos(B) \\ {a}^{2} = {7}^{2} + {3}^{2} + 2(7)(3) \: cos(60) \\ {a}^{2} = 49 + 9 + \:21 = 79 \\ a = 8.88$

at the gym club there are 5 males for every 3 females. the total attendance at the gym last week was 520. how many were males?

sattari [20]

We can say that the ratio of males to females is 5:3 and we can solve this:

The total number of parts is 5+3 = 8

520/8 = 65

We can rewrite the ratio as:

5*65:3*65

325:195

Therefore there was 325 males

What is the percentage of 483/1000

ohaa [14]

To convert fraction into percent we have to make 100 in the denominator. We can do this by dividing/multiplying numerator and denominator by the same number.
Lets do this
$\frac{483}{1000}= \frac{483:10}{1000:10}= \frac{48.3}{100} = 48.3%$ - its our reuslt
