45  =  5  * 3^2

9  =  3^2

Take  the  factor(s)  that  is / are  common to  both  =  3^2   =  9

This is  the GCF   ....

After redoing it, I got 576.38...

No Prob

Thanks! I managed to get 592.5, but I'm not sure if it's correct...

Find  the  distance  from  B to C  =  sqrt  [ (47 - 16)^2  +  (34 - 16)^2 ]  =     (1)

Then....find   the distance  from A  to B  =  sqrt  [ (16 - 8)^2  +  ( 34 - 20)^2 ]  =  (2)

Take  the  product  of  BC * AB  =    (1)  * (2)     =   the area

Let  me know  if you get stuck ......

I forgot to say my answer is B I think

(3 + ((1/9)*3) + (3/8) = 3 + 1/3 + 3/8 = 3 17/24

The formula of the triangle is 1/2 x b x h

The base of the triangle is 8 while the height is also 8

1/2 x 8 x 8 = 32 so B is the answer

We  have  a right triangle  with  legs  of  8 and 8

Area  =   product  of leg lenghts   /   2    =   ????

The GCF is 45 and 9 is 9.

Thank you so much!

We can find the semicircle which has a Radius of one. The formula of finding the area of the 

half circle is 1/2\(\pi\)r^2. We know that the radius is one so we plug in that 1 for r. So our area of the semicircle is 1/2\(\pi \)

We can easily find the area of the rectangle which is 32cm.

Now we have our last figure which is the triangle. As shown, we know that the height of the triangle is 5cma and the base is 2 cm

1/2 x 2 x 5 = 5cm

Now we add all of the area 32cm + 5cm and 1.6cm ( which is half of pi) and the answer is 38.6cm^2

Hope this helps!

From  top to bottom

2 + 1   =  3

2 + 1   =  3

1 + 1/2  = 1.5

(1/2) (3) (1)  =  1.5

Total estimated  area   =  3 + 3 + 1.5 + 1.5  ≈  9 units^2

4 x 3 x 1.4  = 16.8 cm^3

Therefore the answer is D

This link has the answer.

Volume   =  4 * 3  * 1.4   =    ????

Call N  = the  number of dollars  2N  the  number of  quaters.....so  we  have

,25(2N)  + 1N   =   96

1.50N  =  96

N  =  96  / 1,50   =  64   dollars

2(64)   =    128  quarters

We need to see some  sort  of diagram  to  answer this.....

notice that\(a^2 + b^2 + c^2 - ab - ac - bc = \frac{(a-b)^2 + (b-c)^2 + (a-c)^2}{2}\) and this equals to 0, so a - b = b - c = a - c = 0, therefore a = b = c, so there are 100 ordered triples. 

Sorry but is there a diagram or a actual question?

I counted 24 ways total.

Area  of a trapezoid  =

(1/2) height  *  (  sum of base lengths)  =

(1/2) *(19)  ( 46 + 26)  =

(1/2)  (19) ( 72)  =

36 * 19  =

684 m^2

Or take the average of the two bases (the parallel sides)   and multiply by the height  (given as 19 in this example)  to find area.
