From the expression, the price is directly proportional to the boxes with k being the constant. therefore he bought 4 boxes for 25.6 having the initial constant to be 6.4
if he bought 10 boxes having a constant of 6.4 it becomes y=6.4*10 which becomes 64.
The dice only has 6 sides so if you need to roll a 2 or less that only leaves the number one. So it would be 2/6
Answer:
i) k = 36.8
ii)y = 36.8/square root of x
iii)y = 1.4
Step-by-step explanation:
If y is inversely proportional to square root of x;
then the two variables are related by,
y = k/ square root of x
i)Value of k when...x = 8 and y = 13,
substitute into the equation above..so as to find the value of k
13 = k/square root of 8
;k = 13 × square root of 8
;k = 36.8
ii)Then substitute the value of k with...36.8
y = 36.8/square root of x
iii)If x = 27...then y =;
y = 36.8/27
y = 1.4

Answer:
Vertical= 61.43 miles
Horizontal=43.02 miles
Step-by-step explanation:
We use the trigonometric ratios for a right angled triangle to calculate the components.
The vertical is the adjacent while the horizontal is the opposite.
The vertical is calculated as follows:
V= 75 Cos 35° =61.43 Miles
The magnitude of the horizontal H is calculated as follows:
H= 75 Sin 35° = 43.02 miles
