Answer:

She has 16 brownies

Step-by-step explanation:

Initially cut rectangular pan in to two halves.

Then cut each half in half again.

Now total pieces = 4

Now repeat cutting half on other side:

total pieces =8

Now divide each half into another half.

total pieces = 8 x 2 = 16

As can be shown in figure:

Black = first half

pink = dividing each half into another half.

Answer:

C. 3x

Step-by-step explanation:

The first two choices give 1 solution each.

The last choice gives an infinite number of solutions.

Choice C. gives no solution.

3x + 9 = 3x

Subtract 3x from both sides.

9 = 0

Since 9 = 0 is false, equation 3x + 9 = 3x has no solution.

Lana is the oldest of four sisters. Her youngest sister is half her age. The other two sisters are twins 2 years younger than La
True [87]
If Lana's age is L, her youngest sister is L/2 (or 0.5L) and the twins L-2.  Add all these together (remember that there are two sisters who are L-2 years old):
0.5L + L-2 + L-2 + L = 45
Simplify the L's by adding them all together, we get:
3.5L - 2 - 2 = 45
3.5L - 4 = 45
Now add 4 to both sides:
3.5L = 49
Now divide both sides by 3.5
L = 49/3.5 = 14.  Now we know that Laura is 14, so her youngest sister must be 7.

Step-by-step explanation:

Step 1: you see 45°, which gives you a easy conversion \frac \pi 4).

Now, t = 392.7 \mu s = 392.7* 10^{-6} s, start replacing.

V= 50 cos ( 2* 10^3 * 392.7 *10^{-6} -\frac \pi 4) = 50 cos (0.7854 - \frac \pi 4) =\\ 49.999999999999974312306505198184 V
