Answer:

1.71 hours

Step-by-step explanation:

Wade's work rate is 1/4 room/hour

Rhoda's work rate is 1/3 room/hour.

Let the time taken for both of them working together be x.

This means 1/4(x) + 1/3(x) = 1

(4x + 3x)/12 = 1

7x/12 = 1

7x = 12

x = 12/7 = 1.71

Given that f(x) = x2 − 3x + 3 and g(x) = the quantity of x minus one, over four, solve for f(g(x)) when x = 5.
Katena32 [7]

g(x) = the quantity of x minus one, over four

g(x) = (x-1)/4

g(5) = (5-1)/4

g(5) = 4/4

g(5) = 1


f(x) = x2 − 3x + 3

f(g(5)) =1^2 − 3(1) + 3

f(g(5)) = 1 - 3 + 3

f(g(5)) = 1

A triangle has three sides: a, b, and c. Side a = 72 feet, and side b = 154 feet, and side c = 170 feet. True or false: this tri
Juliette [100K]

Answer:

True

Step-by-step explanation:

If the triangle was a right angled triangle then we can prove it using the Pythagoras theorem: c² = a² + b²

c is the largest side and a and b are the two smaller sides of the triangle.

So if this is true then √72² + 154² should be 170:

170² = 72² + 154²

28900 = 5184 + 23716

28900 = 28900

So we have proved using Pythagoras theorem that the triangle is a right angled triangle.
