By Pythagoras Theorem,
Length= (20^2 - 15^2)^0.5= (175)^0.5=5√7
24 (no. Of instalments) x 45 (price) = 1,080$.
Then you need to work out the proportion 1080 is of 990- so 1080/990 which equals 1.0909. Times that decimal by 100 to get a percentage- giving you the answer of 109% of original price.
3/4 is 45 minutes, cause a quarter of an hour is 15 minutes. 6-9 = -3 so you basically do Noon subtracted by another 3 hours which is 9am, then subtract those 45 minutes
6pm - 6 hours = 12pm
(Noon) 12pm - 3 hours= 9am
then 45 minutes
9am - 45 minutes
8:15AM
I think the answer will be Exactly where she started from as she walk 5 steps forward, then 5 back so she is basically getting nowhere.
Answer:
14 kilometers
Step-by-step explanation:
This is really about calculating perimeter.
So we need the lengths of all the sides of this right triangle.
Notice all the legs are 4 units or 4 kilometers
the hypotenuse is 4*root(2) because this is a 45-45-90 triangle.
so
Perimeter = 4 + 4 + 4
let us add: P = 4 + 4 + 4root(2) = 13.656854 km.
the nearest kilometer is 14 km.
