Answer:
7650 W-h
Step-by-step explanation:
1 day = 24 hrs
4 days and 6 hours = 4(24) + 6 = 102 hours
given
24 hrs (i.e 1 day) ------> consumes 1800 W-h
1 hour ------> consumes 1800/ 24 = 75 W-h
102 hrs (i.e 4 days 6 hrs) = 75 W-h x 102 = 7650 W-h
Equation- 8x(12+7-9)-(4+10)
Answer- 80x−14
Answer:
If f(x)=g(x), the solution is x=-2
Step-by-step explanation:
We are given:
We need to find the solution if f(x)=g(x)
Now solving for f(x)=g(x)
If f(x)=g(x), the solution is x=-2
Answer:
157.6m
Step-by-step explanation:
Given
Horizontal distance = 181m
Length of the rope =240m
To know how high above Kayla was, we will use the Pythagoras theorem.
According to the theorem;
d² = x²+y²
x is the horizontal distance
y is the vertical distance
d is the length of the rope
Substitute
240² = 181²+y²
y² = 240²-181²
y² = 24839
y = √24839
y = 157.6m
Hence the boat is 157.6m above Kayla
