In a bag, there are 10 black plastic chips, 7 yellow, 5 red, and 3 green.

Total number of chips = 10+ 7 + 5 + 3 = 25

Probability = \frac{Number \ of \ particular \ chips}{total \ number \  of \ chips}

Probability ( back drawn) = \frac{10}{25}}

Two chips are drawn at random with replacement.. So black is replaced

Probability ( red drawn) = \frac{5}{25}}

Probability (black, then red) =  \frac{10}{25}} *  \frac{5}{25}}

=  \frac{50}{625}}=  \frac{2}{25}}

22. The area of a triangle can be represented by the expression 14x^5 + 63x^2. If the base is 7x^2, write
kkurt [141]

Answer:

h = 4x ^ 3 + 18

Step-by-step explanation:

The first thing you should know for this case is that the area of a triangle is given by:

A = (1/2) * (b) * (h)

Where,

b: base.

h: height.

Clearing the height we have:

h = ((2) * (A)) / (b)

Substituting the values

h = ((2) * (14x ^ 5 + 63x ^ 2)) / (7x ^ 2)

Simplifying the expression:

h = ((2) * (2x ^ 3 + 9))

h = 4x ^ 3 + 18

answer

an expression to represent its height is

h = 4x ^ 3 + 18

The ex- suffix often correlates a word to mean "outside", while the in- suffix often correlates a word to mean "inside". An exterior angle of a polygon would mean "an angle outside of a polygon". An interior angle of a polygon would mean "an angle inside of a polygon". Three exterior angles of this polygon would be angle B, angle D, and angle A. This is because these angles are outside of the polygon due to the extending lines from the shape. Two interior angles of this polygon would be angle 6 and angle 8 (explanation was given when I first began answering this question). Angle 9 would be exterior since it is outside of the polygon. Two exterior angles of the polygon that are congruent are angle D and angle 9, since they are both 90 degrees (right angles).

I can't find the answer to this anywhere so you'd be a huge help!
miv72 [106K]

Answer:

The answer would be d

Step-by-step explanation:

10^0 would be 0 because multiplying anything by 0 would result in 0 and 10^1 would be 10 and 10^2 would be 100 so adding them together would be 110. Hope this helped :)
