Answer:
0.32km
Step-by-step explanation:
The speed that a tsunami can travel is modeled by the equation s = 356 StartRoot d EndRoot , where S is the speed in kilometers per hour and d is the average depth of the water in kilometers.
This is written mathematically as:
S = 356√d
What is the approximate depth of water for a tsunami traveling at 200 kilometers per hour?
S = 200km/hr
Hence:
200km/hr = 356√d
Divide both sides by 356
200/356 = 356√d/356
√d = 200/356
Square both sides
(√d)² = (200/356)²
d =(0.5617977528)²
d = 0.3156167151km
Approximately = 0.32km
Let number of caps =x
charge of one cap =$6
charge of x caps =6x
shipping fee =$25
total budget =$1000
let us make an inequality equation here,
Since amount cannot be greater than 1000 , so
25+6x ≤1000
6x≤975
x≤162.5
rounding off ,
x≤163
So she can buy maximum 163 caps
3.10/155= 0.02 } subtract = 0.07 more
7.65/85= 0.09 }
All numbers in each number add up to 9, i dont know if you understand me,
for example:
1+8=9
2+2+5=9
2+7=9
