Refer to the diagram shown below.

By definition,
sin(35°) = 17000/x
Therefore
x = 17000/sin(35°) = 29,638.6 ft

Answer: 29,638.6 ft

A cab driver is paid $6 plus $0. 45 per mile driven. Which expression shows the amount of money the cab driver earns in m miles?
Leni [432]

Algebraic expression is the expression which consist the variables, coefficients and the constants. The expression for the condition given in the problem is 0.45m+6.

Given information

A cab driver is paid $6 plus $0.45 per mile driven.

Total number of total miles is <em>m.</em>

<h3>Algebraic expression</h3>

Algebraic expression is the expression which consist the variables, coefficients and the constants. The algebraic expression are used to solve the condition based problems by expressing them into the algebraic form.

As the cab driver is paid $6 as the fixed amount of the taxi irrespective to the mile driven. Thus this is independent to the other variables and written as the constant in the expression.

As the total miles driven by the cab driver is<em> m</em>. The cost of the per mile driven the car is $0.45. Thus the expression for this condition can be given as,

f(m)=0.45m+6

Hence, the expression for the condition given in the problem is 0.45m+6.

Anna does sit-ups to get ready for her first triathlon. When she starts, she does a sit-up every 222 seconds. But, as she gets t
Alexeev081 [22]

Answer:

Choice B) No.

Step-by-step explanation:

When she starts , she does a sit-up every 222 seconds.

But as she gets tired, each sit-up takes longer and longer to do.

It means, each sit-up takes more time than she did at beginning.

So, it is NOT proportional to the time.

If it is proportional, she should take constant number of sit-ups even she get tired.

If the length of a square is 10 feet what is the area?
lawyer [7]
The area of a square is length x width, but as all sides of a square are equal, then you can simply square the length of one side of the square.
The length of the square in your problem is 10 feet, so all sides have a length of 10 feet. You can write the problem for getting the area as 10x10 or 10-squared (10^2).
The answer would be 100 feet.

Jones Co. pays its employees on a graduated commission scale: 2% on first $30,000; 3% on sales from $30,000 to $60,000; and 5% o
Gnesinka [82]
We need to separate his total earnings out into the different categories:

Category 1 (2%): 30,000
Category 2 (3%): 60,000-30,000 = 30,000
Category 3 (5%): 92,000-60,000 = 32,000

To calculate a percentage we multiply by that percentage divided by 100.
Now we can work out the commissions:
1) 30,000*0.02 = $600
2) 30,000*0.03 = $900
3) 32,000*0.05 = $1600

Adding these together, we get $3100
