Answer:

The Constant of Proportionality k is 15.

Step-by-step explanation:

Given:

y varies directly with x .

y = 75 when x = 5

To Find:

Constant of proportionality = k =?

Solution:

y varies directly with x .

i.e. y is directly proportional to x

∴ y = k\times x

Where

k = constant of proportionality {Remain Same}

So, we will find constant of proportionality k,

∴ When x = 5 and y = 75 we have

∴ 75 = k\times 5\\\\k=\frac{75}{5}

\therefore k =15

Therefore the Constant of Proportionality k is 15.

This math question is about logarithm​
Mandarinka [93]

Answer:

(k+2h)/(k+h)

Step-by-step explanation:

log 6 12 = (log a 12)/(log a 6) ( Log base change property)

log a 12 = log a (3*4) = log a 3 + 2*log a 2 = k+2h

log a 6 = log a (2*3) = log a 3 + log a 2 = k+h

log 6 12 = (k+2h)/(k+h)

Help with some math please!!!!!
Blababa [14]

ANSWER

B. 12

EXPLANATION

The given triangle is isosceles, because two of the arms are equal.

The angles directly under these two arms and the base are equal.

Therefore the three angles of the isosceles triangle are

84°, 4x°,4x°

The sum of these angles is 180°

84 + 4x + 4x = 180

84 + 8x = 180

Group similar terms,

8x = 180 - 84

8x = 96

Divide both sides by 8

x = 12

The correct choice is B.

The admission fee at a movie theater is $5 for children and $9 for adults. If 3200 people go to the movies and $24000 is collect
Usimov [2.4K]
For this problem, let x be the number of children and y for adults. Formulate the equations: 1st equation, x + y = 3,200 and 2nd equation 5x + 9y = 24,000. Re-arrange 1st equation into x = 3200 - y. Then, substitute into 2nd equation, 5(3,200-y) + 9y = 24,000. Then, solve for y. The 16,000 - 5y + 9y = 24000. Final answer is, y = 2000 adults went to watch the movie.

A line has a slope of -3 and passes through the point (5,-1). what is the equation of the line?
PSYCHO15rus [73]

Answer:

y = -3x

Step-by-step explanation:

the equation of the line would follow the formula y = mx + b, where m is the slope and b is the y-intercept. the slope is -3 so we would substitute that in for m. and since there is no y-intercept in this situation, our equation would be y = -3x.

i hope this helps :)
