Answer:
48/3
Step-by-step explanation:
Answer: Team one = 1/5
Team 2 = 4/21
Team A is the fastest
Step-by-step explanation: Answer: Team one = 1/5
Team 2 = 4/21
Team A is the fastest
Step-by-step explanation: TEAM A
Tammy working alone in 1hr can clean 1/2
Melissa working alone in 1 hr can clean 1/3
working together in 1hr ,let x represent the area they will clean we have
+
= 1/x
⇒ 3 + 2 = 1/x
5 = 1/x
x = 1/5
TEAM B
Santay working alone can clean 1/4
Leticia working alone in 1 hr can clean 4/5
working together in 1 hr ,let y represent the amount they clean, we have
+
= 1/y
4 + 5/4 = 1/y
21/4 = 1/y
y = 4 /21
comparing x and y , 1/5 is greater than 4/21 , therefore Team A is faster
Answer:
B) x = -1 and x = 6
Step-by-step explanation:
The values that must be excluded from the domain are the values for which f(x) is undefined. Those values are the ones that make the denominator be zero.
We can find the zeros of the denominator by factoring.
... x² -5x -6 = (x +1)(x -6)
The product is zero when either factor is zero, so when x=-1 or x=6.
Revenues > costs
7.5x – 100 > 79.86 + 5.8x
7.5x - 5.8x > 79.86 + 100
1.7x > 179.86
x > 179.86 / 1.7
x > 105.8
Then, the minimum number of objects that need to be sold is 106 (the smallest integer greater than 105.8)
