the volume of a gas varies inversely as the pressure upon it. if the volume of the gas is 160 cubic centimeters at a pressure of
marin [14]
It was stated in the problem that a given volume of a is inversely proportional with the pressure of the system. It means that the as the volume increases, the pressure would decrease and as the volume decreases, the pressure would increase. We would express it as:

V α 1/P

To change it to an equality, we introduce a proportionality constant, k. We do as follows:

V = k/P

So, to determine what is asked, we need to first calculate for the value of k.

V = k/P
At V = 160 m^3 P = 108 cmHg
160 = k / (108)
k = 17280

Thus, at P = 87 cmHg 
V = 17280 / 87 
V = 198.62 m^3

For Spirit Day, each 8th-grade
Mrac [35]

Answer: Option A

P(B and V)=10%

Step-by-step explanation:

To solve this poroblema we use the formula of combinations:

nCr =\frac{n!}{r!(n-r)!}

Where n is the number of objects that can be chosen and you choose r from them.

There are 5 colors of shirts.

The number of shirts that can be made by combining 2 of the 5 possible colors is calculated as:

5C2

5C2=\frac{5!}{2!(5-2)!}

5C2=10

The number of shirts that can be made by combining 2 of the 2 possible colors (B) and (V) is calculated as:

2C2 = 1

Then the probability is:

P(B\ and\ V)=\frac{2C2}{5C2}\\\\P(B\ and\ V)=\frac{1}{10}\\\\P(B\ and\ V)=0.1=10\%

7th GRADE MATH RATIOS HELP TIME ALMOST OUT
wariber [46]

Answer:

8, 40, 28.6, 40, 80, 36.6

Step-by-step explanation:

First find out what the ratio of tulips and roses is for each garden.

Ben: 40÷(4+1) = 8 so 8×4=32 and 8×1= 8

Ina: 40÷(2+5) =5.7 so 2×5.7=11.4 and 5×5.7= 28.6

Use these numbers accordingly.

Seems odd that there would be decimals in a problem like this, consult your teacher.
