It is closer to 1.4
Step-by-step explanation:
This is a 45 45 90 triangle
To find the hypotenuse of this triangle it is any side length times the square root of two.
Formula: Square Root = sqrt
Hypotenuse = SideLength*sqrt(2) ; 1*sqrt(2) = 1.412...
Rounded to the nearest tenths it is closer to 1.4 than 1.5
1. She got 9 questions wrong.
2. I believe the total is $44.80
this is an isosceles triangle... meaning that the two base angles will be equal.
180 - 38 = 142
142 / 2 = 71
x = 71
Answer:
2028.863 to the nearest hundredth
The Number In The Hundredth Place Is 6 And The The Number Following Is 3 And Because Its Less Than 5, The 6 Will Remain.
So Its 2028.86

Answer:
21.25 seconds
Step-by-step explanation:
In miles per second, the speed of the jet is ...
(720 mi/h)/(3600 s/h) = 1/5 mi/s
The speed of the sound is the same:
(1 mi)/(5 s) = 1/5 mi/s
Then the rate of closure between the airplane and the sound is ...
(1/5 mi/s) +(1/5 mi/s) = 2/5 mi/s
To find the time required to close a gap of 8 1/2 miles, we can use the relation ...
time = distance/speed
time = (8.5 mi)/(0.4 mi/s) = 21.25 s
The pilot will hear the thunder 21.25 seconds after the flash.
