Show answer
✓ Correct answer: Single fixed pulley.
A single fixed pulley is a simple machine that offers a mechanical advantage of exactly 1. This means that the input force and the output force are the same. The pulley does not multiply or change the force applied to it. It only changes the direction of the force.

Q3We know that vitamin C is a vitamin that dissolves in water. Hence, which of the following statements is correct?
Show answer
✓ Correct answer: Vitamin C is easily flushed out of your body.
Vitamin C is a water-soluble vitamin, which means it dissolves in water and is not stored in your body for long periods of time. Instead, your body flushes out any excess vitamin C through urine. This is why it is important to consume vitamin C regularly, as your body does not have the ability to store it like it does with fat-soluble vitamins.

Q5A painter has skillfully adorned a piece of canvas that measures 10 x 14 inches with intricate strokes of color. To allow for a framing masterpiece, the painter has thoughtfully decided to create a 1-inch margin devoid of paint, encompassing the entire perimeter of the canvas.<br/><br/>What proportion of the canvas has been adorned with the painter's artistic creation?
Show answer
✓ Correct answer: 68,5%
To determine the proportion of the canvas that has been adorned with the painter's artistic creation, we need to calculate the area of the painted portion relative to the total area of the canvas.<br/><br/>The canvas measures 10 x 14 inches, which means the total area is 10 * 14 = 140 square inches.<br/><br/>The painter has decided to create a 1-inch margin devoid of paint around the entire perimeter of the canvas. This means the painted portion will be 10 - 2 * 1 = 8 inches wide and 14 - 2 * 1 = 12 inches tall.<br/><br/>The area of the painted portion is therefore 8 * 12 = 96 square inches.<br/><br/>To find the proportion, we divide the area of the painted portion by the total area of the canvas:<br/><br/>Proportion = (96 / 140) * 100 = 68.57%<br/><br/>Rounded to the nearest tenth, the proportion of the canvas adorned with the painter's artistic creation is 68.5%.
Q6The supervisor of a small company is planning a new open office layout and believes that employees will require 4 chairs for every 2 desks.<br/><br/>For an office building with 40 desks, how many office chairs will be required based on the ratio of 4 chairs for every 2 desks?
Show answer
✓ Correct answer: 80 chairs
To calculate how many chairs are required for 40 desks, we can use the given ratio of 4 chairs for every 2 desks. <br/><br/>For every 2 desks, we need 4 chairs. So, for 40 desks, we can calculate the required number of chairs as follows:<br/><br/>40 desks * (4 chairs / 2 desks) = 80 chairs<br/><br/>Therefore, the correct answer is 80 chairs.
