Lunna [17]

Answer:

The increase is 9.1%

Step-by-step explanation:

Step 1: Make an equation

$66 * x = 72$

$66x = 72$

Step 2: Divide both sides by 66

$66x / 66 = 72 / 66$

$x = 1.09090$

Step 3: Find the increased

$1 - 1.09090$

$0.091 * 100$

9.1%

A bakery sold 36 brownies in a day, which was 30% of the total items sold that day. What was the total number of items the baker

babymother [125]

Answer:

120

Step-by-step explanation:

We know that 36 is 30% of total items

So our equation would be 36/? = 30/100

From there we cross multiply so 36x100 = 3600

From there, we divide 3600 by 100

Therefore, your answer is 120

I’m sure this is easy but i'm gonna ask anyway

Arada [10]

No, it's always okay to ask if you don't understand a question. Anyway, for this problem, we just have to plug in the value for V to solve for P :

$P = 4V^{ \frac{1}{3}} \\ P = 4(125)^{ \frac{1}{3}}$

A number to the power of 1/3 is the same as taking a cube root.

$P = 4(125)^{ \frac{1}{3}} \\ P = 4(5) \\ P=20$

The perimeter of one face of the cube is 20m.
