3+(5+8)
The Associative Property of Addition states that you can add or multiply numbers any way, it doesn't matter how they are grouped.

In this figure, sin(a) = 23

WITCHER [35]

$a$ and $b$ are complementary, or $b=\dfrac\pi2-a$ . So

$\cos b=\cos\left(\dfrac\pi2-a\right)=\sin a$

and so $\cos b=\dfrac23$ .

Please help me Im almost done

Answer:

$\mathsf {x = 76}$

Step-by-step explanation:

The given pair of angles lie on a line, hence they are classified as linear angles. They possess the property by which their sum is equal to 180°.

$\textsf {Solving :}$

$\implies \mathsf {x + 17 + 87 = 180}$

$\implies \mathsf {x + 104 = 180}$

$\implies \mathsf {x = 180 - 104}$

$\implies \mathsf {x = 76}$

The glee club has a set of 48 classical cds and a set of 42 show tune cds. each set can be divided equally among the club member

Hoochie [10]

We have to find the GCF (Greatest Common Factor) of 48 and 42 here...

Factors of 48:
1,2,3,4,6,8,12,16,24,48

Factors of 42:
1,2,3,6,7,14,21,42

The largest common factor of these two numbers is 6.

So, there can be a maximum of 6 members in the club..

Hope this helped!

PLEASEEEE HELP FOR BRAINLIST!!!!!!!!!

Same thing as before!

First, we can get rid of d(x) simply by looking at it because we can tell it's linear (it's a straight line). If we look at the table, we can see a(x) is also linear because it has a steady rate of growth. b(x) and c(x) both represent exponential growth. The curved shape of b(x) shows us this is exponential growth, and the exponent in c(x) tells us it's also exponential.
