the altitude of the hypotenuse of a right triangle divides the hypotenuse into segments of lengths 14 and 8. what is the length

lisov135 [29]

Answer:

B. $4\sqrt{7}$

Step-by-step explanation:

The right triangle altitude theorem states that the altitude of a right angled triangles formed on the hypotenuse is equal to the geometric mean of the 2 line segments it creates.

This can be represented as:

$h = \sqrt{(xy)}$

Where,

h = the length of the altitude,

x and y are the lengths of the 2 segments formed.

Therefore, the length of the altitude = $h = \sqrt{(14*8)}$

$h = \sqrt{112}$

$h = \sqrt{16}*\sqrt{7}$

$h = 4\sqrt{7}$

The drama club sold $779 worth of tickets to the school play. Student tickets cost $3 a piece and tickets for everyone else cost

svetlana [45]

Answer:

The equation will be: $3s+5t=779$

Step-by-step explanation:

The number of student tickets that were sold $=s$

and the number of other tickets that were sold $=t$

Student tickets cost $3 a piece and tickets for everyone else cost $5 each.

So, the total cost of $s$ student tickets $=\$3s$ and the total cost of $t$ other tickets $=\$5t$

Given that, the drama club sold total $779 worth of tickets.

So, the equation will be: $3s+5t=779$

you are considering 2 jobs. one job pays $250 per week, plus 4.5% commission on all sales. The second job pays $1,800 per month

Hoochie [10]

The correct answer is A. Not only does $250 a week equal $1000 a month but the commission is also higher.

first job: $250wk = $1000 Month + .045 commission
= $12000 year + .045 commission
second job = $1800 Month + .03 commission
= $21600 year + .03 commission
commission based on sales of $1,000,000

1,000,000 times .045 = $45000
1,000,000 times .030 = $30000

FIRST JOB: $12,000 + $45,000 = $57,000
SECOND JOB: $21,600 + $30,000 = $51,600

The answer is definitely A.
