for s=150 ft

Answer:
x = 16
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos60° = 
cos60° =
= 
Multiply both sides by x
x × cos60° = 8, that is
x ×
= 8
Multiply both sides by 2
x = 16

<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
let x represent the number of minutes of running and y represent the number of minutes of swimming, hence:
7x + 9y ≥ 441
The inequality that describes the calories burned is 7x + 9y ≥ 441

Answer:
45600 pounds = 20683.8 kg to the nearest 10th.
Step-by-step explanation:
Consider the provided measurement
1 kg = 2.20462 pounds
1 pound = 0.453592 kg
Multiply both the sides by 45600.
1×45600 pound = 0.453592×45600 kg
45600 pound = 20683.812 kg
Now convert it to the nearest tenths as shown.
45600 pound = 20683.8 kg
Hence, 45600 pounds = 20683.8 kg to the nearest 10th.
