Is it possible for the two triangles described below to be similar? Two angles of one triangle measure 60° and 70°. Two angles o
Aleonysh [2.5K]

Answer:

  no

Step-by-step explanation:

Similar triangles have angles with the same measures.

  angles in the first triangle are 50°, 60°, 70°.

  angles in the second triangle are 50°, 50°, 80°.

The angles do not have the same values, so the triangles cannot be similar.

_____

<em>Comment on the question</em>

When 2 of the three angles are different, the third angle cannot make the triangles similar. We don't even need to compute the third angle to answer this question.

Find the 6th term in the expansion of (x + 2)9.
Masja [62]

Answer:

4032x^4

Step-by-step explanation:

Use the 10th row of Pascal's Triangle to get you where you need to be.  You need 10 rows because any polynomial raised to the 9th power has 10 terms.  Those 10 terms are, in order:

1, 9, 36, 84, 126, 126, 84, 36, 9, 1

Setting up for the first 6 terms:

1(x^9)(2^0)+9(x^8)(2^1)+36(x^7)(2^2)+84(x^6)(2^3)+126(x^5)(2^4)+126(x^4)(2^5)+...

The 6th term is the last one.  It goes on from there, but I stopped at the 6th term, since that is what you need.

Simplifying gives us:

126(x^4)(32)

and multiplying gives us:

4032x^4

Ken has a toy chest with hot wheels cars. He has 6 camaros, 2 Lamborghinis, 4 corvettes, 8 Ferraris and 12 mustangs. Ken wants t
ipn [44]
Lamborghini=
fraction = 2/32
Decimal = 0.0625
Percentage= 6.25%

Corvette=
Fraction= 4/32
Decimal=0.125
Percentage=12.5%



Explanation:


Since the problem says “lamborghini OR corvette” you need to add the probability amount of both cars together. There are 2 lamborghinis and 4 corvettes, so 2+4=6. Now, put this number over the total amount of all cars. 6+2+4+8+12=32. So, the probability will be 6/32 which simplifies to 3/16. In decimal form this is .1875, and in percent form this is 18.75% (move the decimal 2 places to the right)
