It looks like you want to find the short leg (x) of a right triangle with long leg 15 and hypotenuse 18. The Pythagorean theorem gives the relationship between the sides of a right triangle.
  18² = 15² + x²
  324 = 225 + x²
  x² = 324 - 225 = 99
  x = √99 ≈ 9.9

The appropriate choice is ...
  b) 9.9

The second doughnut glazing machine can glare 78 dozen doughnuts in
seropon [69]

Answer:

t = 3.46 hours, or 3 hours 28 minutes

Step-by-step explanation:

78 dozen donuts in 2 hours immediately reduces to 39 dozen/hour.

Donuts produced as a function of time:   D(t), where t is the number of hours the macine runs.

Set D(t) = 135 dozen = (39 dozen/hr)t.

Solving this equation for t, we get:

t = 135/39 hours, or t = 3.46 hours, or 3 hours 28 minutes

I need help ASAP! And work needs to be shown!
spin [16.1K]

Answer:

32 x p/100 = 40

(Solve for P)

Multiply by 100 on both sides

32x = 4,000

Divide by 32 to get:

X = 125%

(reason why you multiply by 100 is because opposite of division is multiplication and we multiply the number "100" because we always multiply the denominator to both sides when having a fraction so you can solve for p or whatever. And that means p/100 x 100 it means p because since p is not a known value we consider 1/100 x 100 = 1, a variable by itself means 1 so you could just put p by itself next to the number its multiplied by which is 32 so it would be 32p because your multiplying both and the opposite of that would be dividing by 32 on both sides because you are getting rid of the 32 so therefore you will be left with: X = 125)

Consider the function FX equals -2/3 X -24 which conclusions can be drawn about F negative 1X select two options a F negative 1X
omeli [17]

The conclusions that can be drawn about f–1(x) are:

  • f^-^1(x) has an x-intercept of (-36, 0)
  • f^-^1(x) has a range of all real numbers.

<h3>Calculations and Parameters:</h3>

Given:

f(x) = \frac{-2}{3}x - 24

f(x) + 24 = \frac{-2}{3}x

To find x, we would multiply both sides by -2/3

= x= \frac{-3}{2} (f(x) + 24)

f^-^1(x) = -\frac{3}{2} (0) - 36

f^-^1(x) = -36

Therefore, f^-^1(x)  has an x-intercept of (-36, 0)

Furthermore, f^-^1(x) has a range of all real numbers.

Solve for b: 2(b + 3) = b – 4
Reil [10]

Answer:

b = -10

Step-by-step explanation:

2(b + 3) = b – 4

2b + 6 = b - 4

-b             -b

b + 6 = -4

     -6    -6

b = -10
