GEOMETRY. NEED HELP NOW PLEASE!! Find m∠BAC in circle O. - 1

Answers

Answer 1
Answer: So here we go, lines OA and OB are radii of the circle O
since the measurement of ∡ O is given it is easy to find the other measurements.
180-85 = 95°  (all the sides of a triangle = 180°)
That angle divided by two
(95)/(2) = 47.5°
We know that the radii are the sides which makes that triangle isosceles.
So m∡BAC = 47.5°
Answer is B)47.5

Tara works in a clothing store where she earns a base salary of $100 per day plus 12% of her daily sales. she sold $800 in clothing on saturday and $1500 in clothing on sunday. how much did she earn over the two days?

Answers

Saturday: $100 + ($800 x 0.12) = 196
Sunday: $100 + ($1500 x 0.12) = 280

How do I factor 5x^2 + 28x + 32 ?

Answers

Factor:

5x^2 + 28x + 32  =======>  Solution:  ======>   ( x   +   4 ) ( 5x   +   8 )


Steps:  Factor

5x^2 + 28x + 32

Break the expressions into groups:

( 5x^2     +    20x )      +     ( 8x       +     32 )

Factor Out   5x^2   From  5x^2   +   20x   ======>     5x( x   +   4 )

Factor Out the  8   From    8x    +   32    ========>    8 ( x      +    4 )

=       5x (x     +    4 )       +     8 ( x      +     4 )

Factor Out Common term:

x     +        4

Answer =====>  Factor of;  ==>  5x^2 + 28x + 32     ( x      +    4 ) ( 5x      +   8 )



Hope that helps!!!!                                              : )

   
Hi! First, you want to work out your exponets. We have a 5x to the 2nd power (5x^2). Look at it as 5x•5x, “• means to multiply” so that will equal 25x. Next, put it back in the equation. That’ll be 25x+28x+32. Next step is to combine variables . The variables are 25x and 28x. this will equal, 53x. Put that back into the equation, which will now be 53x+32. This will be your answer since you cannot combine those two! Hope this works!
