Answer: B. 15.7 inches

Step-by-step explanation:

The ramp forms a right angle triangle. The height of the ramp above the ground represents the opposite side of the triangle. The length of the ramp represents the hypotenuse of the right angle triangle. The base of the ramp represents the the adjacent side of the right angle triangle. Therefore, to find r, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

r² = 7² + 14² = 49 + 196

r² = 245

r = √245

r = 15.7 inches to the nearest tenth

A carpenter has a piece of wood that is 78 inches long. He wants to cut it so that one piece is five times as long as the other
Lyrx [107]

Answer:

13 and 65

Step-by-step explanation:

x + 5x = 78

(because u want a piece (x) and a piece that's five times longer than x- so 5x. and they should come from a 78 inch piece)

6x = 78

x = 78 / 6

x= 13

(to counter check:  13 * 5 = 65.  

                               65 + 13 = 78  )

Answer:

= -√6

Step-by-step explanation:

1) collect like terms by subtracting coefficients:

3√6 - 4√6

(3-4)√6

2) calculate (3-4):

(3-4)√6

-1√6

3) the coefficient of -1 does not have to be written, but the negative sign remains:

-1√6

-√6

so therefore:

-√6 is your answer

The equation that can be used to represent total tickets sales is 2170 = 5s + 2f + 10a

<h3>Equation</h3>

let

  • Number of students tickets = s
  • Number of faculty tickets = f
  • Number of alumni tickets = a

Expression for number of students tickets sold;

s = f + 15

Expression for number of faculty tickets sold;

f = 2a

Expression for number of alumni tickets sold;

f = 2a

a = f/2

  • Cost of students tickets = $5
  • Cost of faculty tickets = $2
  • Cost of Alumni tickets= $10
  • Total revenue = $2170

2170 = 5s + 2f + 10a
