you're welcome!

thank you!

Do either 9C4 or 9C5 to get 3024.

thank you to whoever can help

by the way its supposed to be a length 5 width 4 grid

Q II has negative values of cosine

sin^2 + cos^2 = 1

(4/5 )^2 + cos^2 = 1

cos^2 = 9/25      cos   = +- 3/5     but we need negative in Q II   so   - 3/5

I'll give you a tiny hint:

(10x+10)² = [2(6x-8)]² 

Now, you're even more confused

Let ABCD be a parallelogram such that AB = 10, BC = 14, and angle A = 45 degrees Find the area of the parallelogram.

Ito time  = i                              Ito RATE =   1 task / i    = 1/i

A = assistant time  =  2i          A*s't RATE                   = 1/2i

One task is completed by both working in 6 hours

    1 task / (1/i  + 1/2i)   = 6

1/(1/i + 1/2i) = 6     solve for  i

1 / ( 3/(2i) ) = 6

3/(2i)  = 1/6

2 i = 18

i = 9  hr        A*s't = 18  hr

This whole method reduces to this:

1/i  + 1/2i = 1/6

3/2i = 1/6

2i = 18

i = 9

Triangle Angle Bisector Theorem

AX / 28 = 21 / 30  

( I'm your guest, but you can trust me)

4 full jars   is                        4  x   3.5 liters

   then add the 1/2 full one            1/2  X  3.5            

Take each line and multiply it  and sum them      0 *3      +    1*9     +     2*10      etc  

    then divide by the total of the second column   3 +  9 + 10 ...... 

YOU are not passing a test if someone else is answering the questions ! 

since this is a test, I dont think anyone can help you, as that is cheating. think back to the formulas you've learned in class, and try to figure it out yourself. 

Slope, m of the given line is    - 3/4     perpindicular is  - 1/m = 4/3

   the answer is one of the choices with   4/3 in it .....  

                  sub in the point (6,-2) into the choices to see which one is true

Area of a quarter circle of radius 12          =     1/4  pi 12^2

    subtract the triangle area:        1/2 b h  =  1/2 12 x 12

perimeter =  hypotenuse of right triangle with legs = 12 and 12             sqrt (12² + 12² )

            +  1/4  pi x d              d = diameter = 24

There are three numbers in A      divide  3   by the total # of numbers in the diagram .....just count how many numbers are in the diagram ....DO NOT add them together.....

            Short leg  |  Long leg  |  Hypotenuse

1)               √3                    3                  2√ 3

2)                3                    3√3                  6

3)              3√3                    9                  6√3  

4)                9                    9√3                  18

All sides of triangle #3 are 3X the sides of triangle #1. The same is for triangles #4 and #2.

Angle DBC = angle DBA = x, angle ABC = 2x

AB = AC, so angle BCD = 2x

Angle ADB external to triangle BDC, so angle ADB = 3x

BD = BC, so angle BDC = 90 - x

angle ADB + angle BDC = 180 ==> 3x + (90 - x) = 180 ==> x = 45

==> A = 90 - x = \(\boxed{45}\)

hi there for the second one i cannot figure out the probability plz
