please help mee i need this done today bc report cards are coming out this Friday i tried solving them but i can't please help mee

Answer:

its be 9th of square centimeter

So in this case f(x) is number of pollinated flowers and x is the days. First you will need to determine the number of flowers pollinated at days 4 and 10 and the days in between.  f(4)= 3(4^2)= 3*16 = 48  f(5)= 3(5^2)= 3*25 =75  f(6)= 3(6^2)=3*36=108  f(7)= 3(7^2)=3*49=147  f(8)= 3(8^2)=3*64=192  f(9)= 3(9^2)= 3*81=243  f(10)= 3(10^2)=3*100=300    Now we need to find the average increase, so that will be the average of the differences between days  [(75-48)+(108-75)+(147-108)+(192-147)+(243-192)+(300-243)]/6  =(27+33+39+45+51+57)/6=42

Answer:

The angles are 54 2/3 degrees and 115 1/3 degrees

Step-by-step explanation:

make an equation for the angles x being one angle and y being the other

16+ 2x =y

Supplementary angles add to 180

x + y = 180

Fill in y with the first equation

x + 16 +2x =180

simplify

3x +16 =180

subtract 16 from both sides

3x = 164

divide both sides by 3

x = 54 2/3

Insert the value of x into the first equation then simplify

16 + 2(54 2/3) =y

16 + 109 1/3 =y

115 1/3 =y

102 minutes=1 hour and 42 minutes

6:45+1 hour and 42 minutes=8:27 p.m.

hence, the answer is 8:27 pm

Answer:

-5/3

Step-by-step explanation:

We have two points on the line  ( 0,2) and ( 3, -3) so we can use the slope formula to find the slope

m = ( y2 -y1)/(x2-x1)

    = ( -3 -2)/(3-0)

   = -5/3

Answer:

(4x -25), (2x + 11)

Step-by-step explanation:

STEP1: Equation at the end of step 1

(23x2 - 6x) - 275

STEP2: Trying to factor by splitting the middle term

 2.1     Factoring  8x2-6x-275 

The first term is,  8x2  its coefficient is  8 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  -275 

Step-1 : Multiply the coefficient of the first term by the constant   8 • -275 = -2200 

Step-2 : Find two factors of  -2200  whose sum equals the coefficient of the middle term, which is   -6 .

     -2200   +   1   =   -2199     -1100   +   2   =   -1098     -550   +   4   =   -546     -440   +   5   =   -435     -275   +   8   =   -267     -220   +   10   =   -210     -200   +   11   =   -189     -110   +   20   =   -90     -100   +   22   =   -78     -88   +   25   =   -63     -55   +   40   =   -15     -50   +   44   =   -6   That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -50  and  44 

                     8x2 - 50x + 44x - 275

Step-4 : Add up the first 2 terms, pulling out like factors :

                    2x • (4x-25)

              Add up the last 2 terms, pulling out common factors :

                    11 • (4x-25)

Step-5 : Add up the four terms of step 4 :

                    (2x+11)  •  (4x-25)

             Which is the desired factorization

Final result :

(4x - 25) (2x + 11)

Answer: 18 and 99 degrees

Step-by-step explanation:

The sum of the measures of the other 2 angles is 360 - 219 - 24 = 117 degrees.

So the other two angles measure (2/13)(117)=18 degrees and (11/13)(117)=99 degrees

Answer:

x=16⁰

Step-by-step explanation:

I AM NOT QUITE SURE OF THE ANSWER, but they are vertically opposite angles which in turn means that they are equal.

so you can equate the two sums they have given.

3x-3 = 2x+13

Take the numerical terms onto the right hand side and the 'x-terms' to the left hand side.

3x-2x = 13+3

That would leave you with,

x=16⁰

Answer:

x=3

Step-by-step explanation:

6x+5=3x+14

Group like terms:

6x-3x=14-5

3x=9

Divide both sides by 3 to get x:

x=3

Answer:

[tex]\frac{64}{27}[/tex]

Step-by-step explanation:

We can use the "keep-change-flip" method to divide fractions

   Keep: [tex]\frac{8}{9}/\frac{3}{8}[/tex]

Change: [tex]\frac{8}{9}*\frac{3}{8}[/tex]

      Flip: [tex]\frac{8}{9}*\frac{8}{3}[/tex]

Now we can solve by multiplying across:

[tex]\frac{8}{9}*\frac{8}{3} =\frac{8*8}{9*3} =\frac{64}{27}[/tex]

Answer:

2 10/27

Step-by-step explanation:

8/9 / 3/8 = 8x8 / 9 x 3 = 64/27

64/27 = 2 10/27
