Paul [167]

The number of salads Ishaan and his friends can afford is 6 salads.

<h3>What are Word Problems?</h3>

Word Problems in mathematics involve crucial understanding and the use of variables and arithmetic operations to solve real-life cases.

From the given information;

  • The total amount with Ishaan and his friends = $40
  • If they decided to spend the money on salad(x) and one salad(x) cost = $6

Thus, the number of salads they can purchase is:

\mathbf{x = \dfrac{\$40}{\$6}}

x = 6 salads remaining $4

Therefore, we can conclude that the number of salads they can purchase with $40 is 6 salads with a remaining amount of $4.

What is m CBT? Use a protractor to help you.
AnnyKZ [126]
M∠CBT is not 120°.

You have to notice the start of the measure of the angle is on the point of C. It is the 0°.

If the segment BT is straight up from the point of B, its angle will be 90°. 

Since the segment does not form a right angle, its measure of angle is less than 90° but more than 0°
