PLEASE HELP!!!!!!!! A cardboard box is 32 centimeters long, 15 centimeters wide, and 6 centimeters tall. The box does not have a top. How much cardboard was used to make the box?

Answers

Answer 1

Answer:

Answer:

1044 cm²

Step-by-step explanation:

Since the box doesn't have the top, the total surface area includes 4 sides and the bottom.

S = 32(15) + 2(32 + 15)(6) = 1044 cm²

Cardboard used is 1044 cm²

The pressure, P, of a gas varies inversely with its volume, V. Pressure is measured in units of Pa. Suppose that a particular amount of gas is initially at a pressure of 84 Pa at a volume of 51 L. If the volume is expanded to 153 L, what will the new pressure be?A.
495 Pa

B.
153 Pa

C.
17 Pa

D.
28 Pa

Answers

From the problem, pressure is inversely proportional to its volume. It can be represented as:

P = k (1/V)

where k is the proportionality constant. To solve the problem, we use the information given as follows:

P1 = k (1/V1)
P2 = k (1/V2)
Since k is equal for both equations, we can substitute one equation to the other. We obtain,

P1V1 = P2V2
84 Pa x 51 L = P2 x 153 L
P2 = 28 Pa

Thus, the answer is D. This can be expected since the volume increased and based from the equation pressure and volume are inversely related.

D, 28 pa. I just took this test

Multiply (3x – 5y)(2x + 3y)

Answers

Answer:

6x² - xy - 15y²

Step-by-step explanation:

To multiply these two binomials together, we can use FOIL. FOIL stands for:

First: Multiply the first terms of the binomials together.

Outer: Multiply the first term of the first binomial by the second term of the second binomial.

Inner: Multiply the second term of the first binomial by the first term of the second binomial.

Last: Multiply the second (last) terms of the two binomials together.

(3x - 5y)(2x + 3y) = (3x)(2x) + (3x)(3y) + (-5y)(2x) + (-5y)(3y)

= 6x² + 9xy - 10xy - 15y²

= 6x² - xy - 15y²

Answers

Answer=12%

The lower the percent, the more unlikely that the event will happen. Since 12% is the lowest percent, it is also the most unlikely of the options.
