4. A cruise ship travels in the direction of 55degrees for 40 miles, then changes course to a direction of 100 degrees for 35 mi

olga2289 [7]

Answer:

69.3 mi

Step-by-step explanation:

Let x represent the distance of the ship from its original position.

x²= 40² + 35² -2(40)(35)cos(135)

$x^{2} =4804.9$

$\sqrt{x} ^{2} = \sqrt{4804.9}$

Ming used the calculations shown to find out how much he would spend on 6 pounds of ground beef if 10 pounds of ground beef cost

Angelina_Jolie [31]

Answer:

He determined pounds per dollar by dividing 10 by 25 but wrote the unit rate as a dollar value.

Step-by-step explanation:

Given

$\frac{10\ pounds}{\$25} = \frac{10\ pounds}{25} / \frac{\$25}{25} = \frac{0.4}{1}$

$Unit\ Price = 40\ cents$

$40\ cents * 6 = \$2.40$

Required

Determine Ming's error

Ming's error is from here

$\frac{10\ pounds}{\$25} = \frac{10\ pounds}{25} / \frac{\$25}{25} = \frac{0.4}{1}$

He calculated the unit rate as pound per dollar.

So, after calculating the unit rate, the unit should be:

$Unit\ Rate = 0.4\ pound/\$$

But instead, he solved as:

$Unit\ Rate = \$0.4/ pound$

Hence, (a) is correct
