The volume of a sample of oxygen is 200.0 mL when the pressure is 3.00
atm and the temperature is 310 K. What is the new temperature if the
volume increases to 400.0 mL and the pressure decreases to 2.00 atm?*
322.3K
482.8 K
O 413.3K
686.0 K

Answers

Answer 1

9514 1404 393

Answer:

  C  413.3K

Step-by-step explanation:

Temperature is proportional to volume and pressure. Pressure has decreased by a factor of 2/3, and volume has increased by a factor of 400/200 = 2. So, the new temperature is ...

  (310 K)(2/3)(2) = 413 1/3 K ≈ 413.3 K

A rectangle has a a perimeter of 68 ft. The length and width are scaled by a factor 1.5.

The perimeter of the resulting rectangle is ___ ft.

Answers

Answer and Step-by-step explanation:

Answer and Step-by-step explanation:

Here is the equation for finding the sides (just to show):

68 = (2L + 2W)

We multiply L and W by 2 because there are two of the lengths and 2 of the widths.

Now, we add the scale factor to the outside, but on both sides of the equation.

68 × 1.5 = 1.5(2L + 2W)

Multiply 68 by 1.5.

102 = 1.5(2L + 2W)

The answer is 102.

The perimeter of the resulting rectangle is 102 ft.

Answers

Answer:

36 unit^2.

Step-by-step explanation:

The area is the sum of the 2 triangles with each having base between the points (-2,4) and (-2,-4).

The base is4 - -4 = 8.

Area of a triangle = 1/2 * base * height.

Area of the kite = 1/2 * 8 * 3 + 1/2 * 8 * 6

Lines A and B are parallel
m<6 = [?]°

Answers

Answer:

Im pretty sure its 55

Step-by-step explanation:

So it adds to a 180 degree angle

When lines A and B are parallel m<6 (the measure of angle 6) is 55° .

If lines A and B are parallel and ∠4 and ∠6 are consecutive interior angles, then we can use the property that consecutive interior angles add up to 180°.

Given that ∠4 is 125°, we can substitute this value into the equation :

∠4 + ∠6 = 180°.

125° + ∠6 = 180°.

To find the measure of ∠6, we can subtract 125° from both sides :

∠6 = 180° - 125°.

∠6 = 55°.

Therefore, m<6 (the measure of angle 6) is 55°.

Answer:

The median for Set A is greater than the median

for Set B.

Step-by-step explanation:

From the boxplot attached, we can deduce the following :

Median (vertical line in between the box on a boxplot).

Median, set A = 30

Median, set B = 29

Range = (Maximum - Minimum. Value)

Set A :

Maximum = 35 ; Minimum = 21

Range = 35 - 21 = 14

Set B :

Maximum = 37 ; Minimum = 24

Range = 37 - 34 = 3

Hence, from the options, the only correct statement is The median for Set A is greater than the median for Set B.

I’m assuming it’s referring to two regular dice? (2 dice with numbers 1-6 labeled)
The divisors of 8 are 1,2,4, and 8
I’m interpreting as rolling the number on the die not the sum of the dice
So it’s 3/6 numbers on the die or 1/2 and there are two dice to rolling a divisor of 8 on both dice is 1/2 x 1/2 or 1/4
