Let the distance remaining after time t be x miles.
Distance traveled by Alan = (6-x) miles
Distance traveled by Soren = (8-x) miles
Time takes by the two is the same. Therefore,
(8-x)/12 = (6-x)/7 => 7(8-x) = 12(6-x) => 56-7x = 72-12x => 12x-7x = 72 -56 => 5x= 16 => x = 16/5 = 3.2 miles.
And then, time taken (t) = (8-3.2)/12 = (6-3.2)/7 = 0.4 hours
Answer:
7.8 cm and 25.3 cm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
?² + 7² = 10.5²
?² + 49 = 110.25 ( subtract 49 from both sides )
?² = 61.25 ( take the square root of both sides )
? =
≈ 7.8 cm ( to 1 dec. place )
Then
P = 10.5 + 7 + 7.8 = 25.3 cm
Step-by-step explanation:
what is the problem ? what needs to be done ?
all that you are showing here is the definition of a number range.
it means all numbers, for which 1.3 is smaller or equal.
in short, all numbers that are greater or equal to 1.3.
Answer: 80
Step-by-step explanation:
7824/10 = 782.4
The value represented by 8 is 80 or 8 tens.
