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:
10 and 11
Step-by-step explanation:
Let the first integer be x.
Then the next one, since it's consecutive, must be (x+1).
The two equals 21. Thus:
Combine like terms:
Subtract 1 from both sides:
Divide both sides by 2:
So, the first integer is 10.
And the second integer is 10+1=11.
Answer:
BECAUSE
Step-by-step explanation:
Originally the word “corn” came from the Germanic word “kurnam,” meaning “small seed.” In the 17th century, salted beef started taking on the name “corned beef” in some parts of England because of the large “kernels” of rock salt used to preserve it. :)

The surface area is the combined area of all the sides of a figure.
Four sides have an area of 36 cm², so 144 cm²
Two sides have an area of 12 cm², so 24 cm²
144+24 = 168 cm²
