The volume v of a gas kept at constant temperature varies inversely with the pressure p. If the pressure is 24 pounds per square
daser333 [38]

Answer:

V=12\ ft^{3}

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form y*x=k or y=k/x

In this problem

P*V=k

step 1

Find the value of K

For P=24\ psi ,V=15\ ft^{3}

substitute

24*15=k

k=360

the equation is P*V=360

step 2

For P=30\ psi ,V=\ ft^{3}

substitute in the equation

(30)*V=360

V=360/30=12\ ft^{3}

A coin is tossed and an eight​-sided die numbered 1 through 8 is rolled. Find the probability of tossing a head and then rolling
ratelena [41]

Answer: 7/8

Step-by-step explanation:

Probability is calculated by number of possible outcomes/ total outcomes

From the question, a coin only has two sides, Head or Tail. Total outcomes is therefore equal to 2

Possible outcome is to toss a head, which is one event

Probability of tossing a head is therefore =1/2

The second part of the question is rolling a die with eight sides.

Here, the die is said to have eight sides, 1,2,3,4,5,6,7,8. Total outcomes is therefore equal to 8

Possible outcome of rolling a number greater than 5 is 3 possibilities, that is rolling 6, 7 and 8.

Pr(rolling > 5) is 3/8

Therefore, Pr ( head; rolling > than 5)

= 1/2 + 3/8

=7/8

I hope this is clear, please mark as brainliest answer

Write an equation of the line in slop intercept form
Marat540 [252]

Answer:

m=-\frac{4}{3}

Step-by-step explanation:

to find the slope use the formula m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{0-4}{0-(-3)}

simplify

m=\frac{0-4}{0+3}

m=\frac{-4}{3}

move the negative in front of the fraction

m=-\frac{4}{3}
