Answer:

14 minutes

Step-by-step explanation:

if Pete is x times fast then Repeat is 3x faster

so if both combine to complete a job in 56 minutes then we have

$x + 3x = 56 \\ 4x = 56 \\ x = 14$

remember Pete is x hence Pete was 14 minutes fast

The units in Shante's apartment complex are consecutively numbered on each floor. The sum of her number and her next

hichkok12 [17]

Answer:

222

Step-by-step explanation:

Let x be the number on Shante's doors. The units in Shante's apartment complex are consecutively numbered on each floor, so the number on next door is x+1.

The sum of these numbers is 443, then

$x+(x+1)=443\\ \\x+x+1=443\\ \\2x+1=443\\ \\2x=443-1\\ \\2x=442\\ \\x=221\\ \\x+1=221+1=222$

The larger of two numbers is 222.

Write the first expression in terms of the second if the terminal point determined by t is in the given quadrant.

Sav [38]

Answer:

tan(t) = √(sec(t)² -1)

Step-by-step explanation:

The relation between tangent and secant is ...

tan(t)² +1 = sec(t)²

Then ...

tan(t) = ±√(sec(t)² -1)

In the third quadrant the tangent is positive, so ...

tan(t) = √(sec(t)² -1)
