Let a = 6.

That would be B. 16 because if a is 6 and is by 2, that means it is multiplication. And multiplication always comes before addition. So. 2 times 6 would be 12, plus for would be 16.

There are two ways you can do this. The first is to plug in the answers and check to see if they are true or false, the other way is to multiply 2 by 6 and then add 4. the answer is B 16, the reason is 2*6 is 12 + 4 is 16. However using the other method is not the best way to do it for the other way. This is because 48 and 30 are multiples of 6

A square region with perimeter 60 inches is made with square inch tiles. Bob removes one tile from the square and rearranges the

icang [17]

Answer:

60 inches

Step-by-step explanation:

The perimeter will be minimized when the tiles are rearranged to form a rectangle with dimensions as close to each other as possible.

<h3>Rectangle dimensions</h3>

The square has a side length of ...

P = 4s ⇒ s = P/4 . . . . . P is perimeter, s is side length

(60 in)/4 = 15 in . . . . length of the side of the square

The square has an area of ...

A = s²

A = (15 in)² = 225 in²

When 1 tile is removed, the resulting area, in square inches, is ...

A = 225 -1 = 15² -1² = (15 -1)(15 +1) = 14×16

<h3>Perimeter</h3>

The perimeter of a rectangle is given by ...

P = 2(L+W)

For this rectangle, the perimeter is ...

P = 2(14 in + 16 in) = 2(30 in) = 60 in

The perimeter of the rectangle is 60 inches.

A ball with mass m kg is thrown upward with initial velocity 28 m/s from the roof of a building 17 m high. Neglect air resistanc

Nutka1998 [239]

a. At its maximum height, the ball has zero vertical velocity, so

$-\left(28\dfrac{\rm m}{\rm s}\right)^2=2(-g)(y_{\rm max}-17\,\mathrm m)$

$\implies y_{\rm max}=57\,\mathrm m$

b. The ball's height in the air $y$ at time $t$ is given according to

$y=17\,\mathrm m+\left(28\dfrac{\rm m}{\rm s}\right)t-\dfrac g2t^2$

Solve for $t$ when $y=0$ :

$17+28t-4.9t^2=0\implies t\approx6.3\,\mathrm s$

What is x3 = 8/27<br> Help me please

SVEN [57.7K]

Answer: x=8/81

Step-by-step explanation

3x divide by 3

8/27 divide by 3

it becomes x=8/27 divide by 3 and 3 becomes 1/3

8/27 x 1/3=8/81

x=8/81
