Find all the missing elements:

Evgesh-ka [11]

Answer:

a=10.8; c=4.3

Step-by-step explanation:

The sum of all the angles in a triangle is 180 degrees.

Two of the angles are given as 40 deg and 120 deg.

Subtract the measures of both from the sum to get the last angle:

180-40-120=20; ∠C=20°

Using Law of Sines: $\frac{a}{sinA}=\frac{b}{sinB}=\frac{c}{sinC}$

$\frac{a}{sin120}=\frac{8}{sin40}; a=\frac{8*sin120}{sin40}; a=10.77837084$

$\frac{c}{sin20}=\frac{8}{sin40}; a=\frac{8*sin20}{sin40}; c=4.25671109$

What is the 10th term in the geometric sequence: 32, 16, 8, 4...?

pav-90 [236]

Hi there
just keep dividing by 2 tell you get to the 10th term
that's one way of doing it
32, 16, 8, 4, 2, 1 , 1/2 , 1/4 , 1/16, 1/32
1/32 is the 10th term

In a school one-third of all 240 students play soccer. Forty four students play both soccer and basketball and sixty students do

stiv31 [10]

Answer:

100 students play only basketball.

Step-by-step explanation:

We are given the following information in the question:

Total number of students in school = 240

Number of students that play soccer =

$\dfrac{1}{3}\times \text{Total number of students}\\\\=\dfrac{1}{3}\times 240 = 80$

n(S) =80

$n(S\cap B) = 44$

$n(S'\cap B') = 60$

Formula:

$n(S\cup B) = \text{Total} - n(S' \cap B')\\n(S\cup B) = n(S) + n(B) - n(S\cap B)$

Putting the values, we get,

$n(S\cup B) =240-60=180\\n(S\cup B) = 180 = 80 - 44 + n(B)\\n(B) = 180 - 80 + 44= 144$

Thus, 144 students play basketball.

Out of these 144, 44 plays soccer as well.

$\text{Student only playing basketball} = 144 -44 = 100$

Thus, 100 students play only basketball and not soccer.
