The second description is not suitable.

It should be "simplify the terms" sice you are just adding 36 and -20.

Consider the given expression,

3\mleft(9u+12\mright)-16=20

Apply the distributive property,

\begin{gathered} 3(9u)+3(12)-16=20 \\ 27u+36-16=20 \end{gathered}

Combine like terms,

27u+20=20

Subtract 20 from both sides,

27u=0

Divide both sides by 27,

u=0

Find the approximate location of 2/3, 1/2, and 3/8 on a number line 0 to 1
schepotkina [342]

Answer:

0.6 (terminating), 0.5, 0.375

Step-by-step explanation:

I would assume you are wanting these in decimal form. In that case, you would have:

2/3 = 0.6 (terminating)

1/2 =  0.5

3/8 = 0.375

Which point is on the circle centered at the origin with a radius of 5 units?
Aleonysh [2.5K]

Answer:

(2,√21)

Step-by-step explanation:

The circle centered at the origin has equation:

{x}^{2}  +  {y}^{2}  = 25

Any point that satisfies this equation lie on this circle.

When x=2, we substitute and solve for y.

{2}^{2}  +  {y}^{2}  = 25 \\ 4 +  {y}^{2}  = 25 \\  {y}^{2}  = 25 - 4 \\ {y}^{2}  = 21

Take square root to get:

y =  \pm \sqrt{21}

Therefore (2,-√21) and (2,√21) are on this circle.

From the options, (2,√21) is the correct answer

The answer to number 3
Reptile [31]

Answer:

  4.5×10^17 m²

Step-by-step explanation:

The radius is half the diameter, so we can make the substitution r=d/2 into the formula to get ...

  A = 4πr² = 4π(d/2)² = πd²

Filling in the given values and doing the arithmetic gives ...

  A = 3.14×(3.8×10^8 m)² = 45.3416×10^16 m²

  A ≈ 4.5×10^17 m²

__

We round to 2 significant digits because that is the precision of the given diameter.
