To find the average over 5 times, we have to divide the total by 5. Therefore, 260/5 = 52 = the average change in your account balance each trips. 260 = amount of money you withdraw, 5 = number of trips made by the ATM. We need to divide due to that if something is spread out equally 5 times, what you get in one time clearly won't be all of it
Answer:
54.1° (1 dp)
Step-by-step explanation:
Let the center point of the rectangle PQRS = M
Calculate the length of the line SM using Pythagoras' Theorem:
a² + b² = c²
(11/2)² + (7/2)² = SM²
42.5 = SM²
SM = √42.5 cm
The height of the pyramid is 9 cm, therefore, MT = 9
Now we have a right angled triangle with base SM and height MT and hypotenuse ST
We want to find the angle TSM, so we can use the trig formula tan x = O/A, where x is the angle, O is MT and A is SM
tan TSM = MT/SM = 9/√42.5
TSM = arctan (9/√42.5) = 54.082088°
So the angle between the line ST and the plane PQRS = 54.1° (1 dp)
<em>1</em>×<em>4+1=5
2</em>×<em>5+2=12
3</em>×<em>6+3=21
So, 8</em>×<em>11+8=96</em>
Answer:
the length would be the same as the other side so the length would be 19.5 and the width 15
