Answer=13 feet long
This information describes a right triangle, with sides 5ft and 12ft.
a²+b²=c²
5²+12²=c²
25+144=c²
169=c²
√169=√c²
13=c
The ladder needs to be 13ft long
Answer:
$927.113
Step-by-step explanation:
50-7=43
43×18.94=814.42
100-15=85
100%=18.94
what about 85%
85×18.94=1609.9÷100=16.099
16.099×7=112.693
814.42+112.693= 927.113

Answer:
7 over 10 and 7,10
Step-by-step explanation:
Answer:the output for a wind speed of 40 miles per hour is 810.8 kilowatts.
Step-by-step explanation:
The power P produced by a wind turbine is directly proportional to the cube of the wind speed S. This means that
P is directly proportional to S
Introducing a constant of proportionality, k, it becomes
P = kS
A wind speed of 37 miles per hour produces a power output of 750 kilowatts. This means that
750 = k × 37
k = 750/37 = 20.27
The expression becomes
P = 20.27S
Therefore, the output for a wind speed of 40 miles per hour would be
P = 20.27 × 40
P = 810.8
