Answer:
2907
Step-by-step explanation:
Hello there i hope you are having a great day :) Your question: A certain television is advertised as a 50-inch TV (the diagonal length). If the width of the TV is 14 inches, how many inches tall is the TV?
So you would need to used the Pythagorean theorem that would be
c^2 = a^2 + b^2
So this would equal letter C as The hypotenuse of the right angle and also letter A and B are the stands on the triangle so C would equal 50 inches and A and B would equal 14 inches.
Then the Hard bit so you would be,
1) a^2 = c^2 - b^2
2) a = √c^2 - b^2
3) a = 50^2 - 14^2
4) a = √ 2,500 - 196
5) a = √2,304
6) A = 26
So the answer would be 26 Hopefully ❤
Answer:
i) 45km/hr
ii)29 min
Step-by-step explanation:
average speed = distanced travelled / time elapsed
It took 36min and need to convert to hr
36min x 
= 
= 
hours
distanced travelled is 27 km;
average speed = 27km / (9/15hr) = 45 km/hr
Add 36min to 0837 becomes 0913, the train will arrive at 0942 and the wait will be the difference of 0942 - 0913 = 29 min
Answer:
A. 8100
Step-by-step explanation:
85 x 86
To estimate, we multiply 85*100, which is the easiest multiplication, as a multiplication by 100 is the same as placing two zeros at the end of the number.
85*100 = 8500
Since 86 < 100, 85*86 < 8500. Thus, the correct estimate is given by option A.
