Answer:

A=75

B=60

C=45

Step-by-step explanation:

5+4+3=12

every triangle is equal to 180 so we divide

180/12=15

then we multiply each angle by 15

5*15

4*15

and 3*15

don't forget to check your work by adding the answers together to get 180

The first thing thing you must do is create an equation for this problem. Remembering that 7.75% = 0.0775

($4,100 × 0.0775 + $4,100 ) + $600

Now, all you have to do is solve it. You will first have to start with the numbers in the parenthesis using the order of operation (PEMDAS).

P = Parenthesis

E = Exponent

M = Multiplication

D = Division

A = Addition

S = Subrtaction

$4,100 × 0.0775 + $4,100 ) + $600

$4,417. 75 + $4,100 + $600

$4,417. 75 + $600 = $5,017.75

Danielle made $5,017. 17 last week.

I hope this helps! :)

A probability experiment has two steps. There are two possible results for the first step, call them "A" and "B". If the result

denis23 [38]

Answer:

Step-by-step explanation:

Two possible results A and B

If the result for the first step was "A", then there would be 4 possible results for the second step.

Let us say the 4 possible results are 1,2 ,3,4

So, Possible outcomes for this case = {A1,A2,A3,A4} =4

If the result for the first step was "B", then there would be 16 possible results for the second step.

Let us say the 16 possible results are 1,2 ,3,4,....,16

So, Possible outcomes for this case = {B1,B2,B3,B4,....,B16} =16

So, Total possible outcomes = 16+4 = 20

Hence there are 20 possible outcomes for this experiment.
