Answer:

\frac{9}{37} or %24

Step-by-step explanation:

Since you have already took a red candy and didn't replace it the normal \frac{10}{38} would be replaced with \frac{9}{37}.

To find this you need to add all the candies together and find the number of specific candies you want, in this case red/9.

Now put the 9 above the total number as a fraction.

In order to find the percent divide 9 by 37

9/37=0.243243243

Simplify it 0.24

Now move the . over to the right two times!

Find the sum of the sequence. 45+46+47+48+...+108
Anna11 [10]
We know, S = n/2 [ a + l ]
Here, a = 45
l = 108

Calculation of n:
a(n) = a + (n - 1)d
108 = 45 + (n - 1)1
108 - 45 = n - 1
63 + 1 = n
n = 64

Now, substitute in the expression:
S = 64/2 [ 45 + 108 ]
S = 32 [ 153 ]
S = 4896

In short, Your Answer would be 4896

Hope this helps!

Find the perimeter.
Lorico [155]

Answer:

12x+9

Step-by-step explanation:

We may find the perimeter of a shape by adding all of it's side lengths.

We can start by adding 2 sides together.

(5x+2)+(3x+8)=8x+10

Because we don't know the value of x, we can only add together the amount of times that it is multiplied.

Now we add the final side.

(8x+10)+(4x-1)=12x+9

Hope this helps friend.

Determine the slope of the line
prisoha [69]

Answer:

2

Step-by-step explanation:

We can find the slope of the line by using the slope formula

m = ( y2-y1)/(x2-x1)  where ( x1,y1) and (x2,y1) are points on the line

Using the points  (0,-4) and  (2,0)

m = ( 0 - -4)/ ( 2 - 0)

   = ( 0+4)/( 2-0)

   = 4/2

    = 2
