Answer:
Total length of the road = 6 3/4 miles.
Each markers are spaced at a distance = 1/8 of a mile.
Step-by-step explanation:
Total length of the road ÷ each marker space =
a) 6 3/4 ÷ 1/8.
b) In order to solve it, we need to convert that fraction into improper fraction:
6 3/4 = 27/4
6 3/4 ÷ 1/8 = 27/4 ÷ 1/8
We need to convert division sign into multiplication sign and flip the second fraction.
27/4 × 8/1
then simplify to get
27 × 2 = 54.
There would be total number of 54 markers of lengths (1/8) of a mile.
I’m pretty sure it’s 14 km. Hope I helped :) Since I did 56 divided by 4 since it will be one cm is 14 km.
Answer:
Step-by-step explanation:
Lets call the rate at which the first panel absorbs solar energy x:
x = 9/7
To find out how much energy the panel will absorb in a certain number of hours, just multiply x by the time:
In 7 hours, energy = (9/7) * 7 = 9MJ
In 8 hours, energy = (9/7) * 8 = (72/7)MJ
Let's call the rate at which the second panel absorbs solar energy y. Therefore, we can write an equation, in x and y, using the information in the question:
5x + 5y = 41
We know what x is, so 5x = 5 * (9/7) = (45/7):
(45/7) + 5y = 41
5y = 41 - (45/7)
41 is the same as (41*7)/7 = 287/7:
5y = 287/7 - 45/7 = (287-45)/7 = 242/7
Divide both sides by 5 to find the value of y (in MJ absorbed per hours, MJ/h):
y = 242/35 = 6.914285714MJ/h
Let's call the time taken for the new panel to absorb 41MJ t:
ty = 41
We know what y is, so substitute that in and solve:
6.914285714t = 41
t = 41/6.914285714 ≈ 5.929752066 hours
I would like to express this value in the SI unit, which is seconds, s:
5.929752066 * 3600 = 21347.1s
