Answer:

60 -047 = 13 in²

Step-by-step explanation:

Paper area: 6 x 10 = 60

15 circles, each circle has diameter: 6 /3 or 10 /5 = 2

each circle area: πr² = 3.14 x 1² = 3.14

15 circles: 3.14 x 15 = 47.1

paper wasted: 60 - 47.1 ≈ 13 in²

Consider the expression 16y^2 . Select the correct statement:

tiny-mole [99]

Step-by-step explanation:

Given expression is:

$16y^2$

We will solve each statement one by one to see which statements are correct.

If y=3/4, the values of 16y^2 is 12

Putting y = 3/4 in expression

$16y^2 = 16 *(\frac{3}{4})^2 = 16 * \frac{9}{16} = 9$

If y=1/4, the values of 16y^2 is 2

Putting y = 1/4 in expression

$16y^2 = 16 *(\frac{1}{4})^2 = 16 * \frac{1}{16} = 1$

If y=3/8, the values of 16y^2 is 4/9

Putting y = 3/8 in expression

$16y^2 = 16 *(\frac{3}{8})^2 = 16 * \frac{9}{64} = \frac{9}{4}$

If y=1/8, the values of 16y^2 is 1/4

Putting y = 1/8 in expression

$16y^2 = 16 *(\frac{1}{8})^2 = 16 * \frac{1}{64} = \frac{1}{4}$

If y=2/3, the values of 16y^2 is 3/4

Putting y = 2/3 in expression

$16y^2 = 16 *(\frac{2}{3})^2 = 16 * \frac{4}{9} = \frac{64}{9}$

Hence,

The correct statement is:

If y=1/8, the values of 16y^2 is 1/4

Simplify. (picture provided, thank you so much)

oksian1 [2.3K]

-5x^4(-3x^2 + 4x -2)

Multiply the number on the outside by each number inside the parentheses:

-5x^4 x -3x^2 = 15x^6

-5x^4 x 4x = -20x^5

-5x^4 x -2 = 10x^4

Now combine them in order of exponents:

15x^6 - 20x^5 + 10x^4
