Answer:
3 3/7 or 24/7 mins
Step-by-step explanation:
Let total job = X
Jeff's rate = X/6
Bob's rate = X/8
Combined rate = X/6 + X/8
(4X × 3X)/24 = 7X/24
7X/24 = X/T
T = X ÷ (7X/24)
T = X × (24/7X)
T = 24/7 mins
Shortcut:
T = product of individual times/sum of individual times
T = (6×8)/(6+8)
T = 48/14
T = 24/7
T = 3 3/7 mins
Answer:
65
Step-by-step explanation:
1/2 which is half of total is green
1/4 is bad and the remaining apples are red
1/2 of 260 = 130 green apples
1/4 of 260 = 65 bad apples
the remaining is 1/4 which is equal to 65 are red apples
Y - y₁ = m(x - x₁)
y - 5 = -2(x - 3)
y - 5 = -2(x) + 2(3)
y - 5 = -2x + 6
+ 5 + 5
y = -2x + 11
If you mean something like 4^3 * 4^14 you have to obey two rules.
1. The base number must be the same for both numbers making up the product.
2. The powers must be added.
In this case 1 and 2 both can be obeyed.
4^3 * 4^14 = 4^(3 + 14) = 4^17
Answer:
$2450
Step-by-step explanation:
One week = 7 days
$350 = 1 day
$ 2450 = 7 days(1 week)
350 * 7 = 2450
