Answer:
The length of the bridge is 300 feet.
Step-by-step explanation:
Let A represent the length of one leg.
Let B represent the length of the other leg (i.e length of the bridge)
Let C represent the length of the Hypothenus.
From the question given above, the following data were obtained:
Length of Hypothenus (C) = 340 feet.
Length of one leg (A) = 160 feet.
Length of the bridge (B) =.?
The length of the bridge can be obtained by using the pythagoras theory as illustrated below:
C² = A² + B²
340² = 160² + B²
115600 = 25600 + B²
Collect like terms
115600 – 25600 = B²
90000 = B²
Take the square root of both side
B = √90000
B = 300 feet
Therefore, the length of the bridge is 300 feet

Answer: 16
Step-by-step explanation:
Total number of laptops ordered= 650
Number of laptops tested= 40
Number of laptops that takes more than 30 seconds to start up= 1
To get the number of laptops that will take 30 seconds to start in the whole shipment goes thus:
Let the number of laptops that will take more than 30 seconds be represented by y.
1 : 40 = y : 650
1/40 = y/650
Cross multiply
40y = 650
y= 650/40
y= 16.25 which approximately gives 16.
There are expected to be 26 laptops that takes more than 30 seconds to start.
First divide 14 by 2 which brings you to 7. Now multiply 7 by 5 and your total number would be 35. Hope I helped!
