Answer: 30

Step-by-step explanation:

Let, he gave x correct answer.

Since, He gets 2 stars for every 5 correct answer.

⇒ For 5 correct answers number of stars = 2

⇒ For 1 correct answer number of stars = \frac{2}{5}

⇒ For x correct answer number of stars = \frac{2x}{5}

According to the question,

He want to get 12 stars,

⇒ \frac{2x}{5}=12

⇒ 2 x = 60

⇒ x = 30

Thus, the minimum number of correct answer is 30.

1. Identify the name and label the parts of the following polynomial: -2x4+24x2-10
laiz [17]
Please write this polynomial as P(x) = <span>-2x^4+24x^2-10, using " ^ " to denote exponentiation.

This is a fourth degree polynomial, since the highest power of x is 4.  Ordinarily, a fourth degree poly would have 5 terms, but here two of the coefficients of the powers of x are zero, leaving only 3 terms.

</span>The lead coeff. of  P(x) = -2x^4+24x^2-10  is -2.

The constant terms is -10.  The exponent of x here is zero (0).

The degree of the middle term is 2 (see 24x^2, above)

Would you please post your other questions separately.  Thank you.

Tpy6a [65]

Answer:

7.5

Step-by-step explanation:

If we look at the 4 by 4 square around the triangle we can just do the area of the square minus the area of the 3 little triangles which is:

4 * 4 - 4 * 1 / 2 - 3 * 3 / 2 - 4 * 1 / 2

= 16 - 2 - 4.5 - 2

= 16 - 8.5

= 7.5

Enter an inequality that represents the description, and then solve.
Natalija [7]
Tony’s backpack can carry weight up to 22 but not more that that
If the variable n represents the total weight carried by tony
Then ; n less than or equal to (n=1+3+3b
=4+3b
Where b represents book
4+3b is less or equal to 22
3b is less or equal to 18
b is less or equal to 6

Therefore Tony’s backpack cannot carry more than 6 books
