Answer:
1 hour and 42.85 minutes.
Step-by-step explanation:
It is found from the process of reviewing that experience survey a roadbed in 3 hours.
Hence, in 1 hour the experience survey 
of the roadbed.
Again, it is found that the apprentice survey needs 4 hours to survey the same stretch of road.
So, in 1 hour the apprentice survey does 
of the roadbed survey.
If they work together then in 1 hour, the survey work will be done by (
)= 
parts.
Therefore, the total survey they will complete working together in 
hours i.e. 1 hour and 42.85 minutes. (Answer)
Answer: (5^3) / (5^7) = 5^ -4
or
1 / 5^4
Step-by-step explanation:
Answer:
P = 6.4 m
Step-by-step explanation:
Hello,
The perimeter is the sum o each side of that square, so:
Psquare = 4*(lenght of side)
P = 4*(1.6m)
P = 6.4 m
PD: PI IS NOT NECESSARY, WORKS ONLY FOR CIRCLE
Best regards
Answer:
x = 13 and y = 13√3
Step-by-step explanation:
Recall that sin Ф = opposite side / hypotenuse, and that
cos Ф = adjacent sice / hypotenuse.
if we recognize that the angle Ф is 30° here, then we know that:
x = opposite side = hypotenuse * sin 30° = 26*(1/2) = 13.
and....
y = adjacent side = hypotenuse*cos 30° = 26*√3/2 = 13√3
In summary, x = 13 and y = 13√3
Answer: 
On a keyboard, you would write [5, infinity)
The square bracket means "include this value" and a curved parenthesis means "exclude this value". We cannot include infinity as it is not a number, so we always use parenthesis with either infinity.
is the same as 
which is also the same as 
which may help lead to set up the interval notation answer.
