Q1Of all the options given, the simple machine that offers a mechanical advantage of exactly 1 is the:
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.
Q2Which organisms incorporate nonliving atoms and molecules into sugars and other organic molecules?
Show answer
✓ Correct answer: Plants
Only green plants carry out photosynthesis, the process that uses energy and nonliving materials to create nutrients. Decomposers (choice A) release nonliving atoms and molecules into the environment. Carnivores (choice B) use plant-made organic molecules to live. Herbivores (choice D) are types of animals that eat plants to obtain their organic molecules.
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.
Q4If the force acting on an object is doubled while keeping the distance constant, what would be the amount of work performed on the object?
Show answer
✓ Correct answer: 2 times as much
As per the formula, if you double the force while keeping the distance constant, the amount of work is also doubled.
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.
Q7A right triangle, which has an area of 24 square feet, consists of one leg that is three times longer than the other leg. To determine the length of the longest side, we need to solve for this value.
Show answer
✓ Correct answer: 12.6
For a right triangle, the area can be calculated using the formula:<br/><br/>Area = (1/2) * base * height<br/><br/>Let's assume that the shorter leg of the triangle is x feet. According to the given information, the longer leg is three times longer than the shorter leg, so the longer leg would be 3x feet.<br/><br/>Using the formula for the area of a triangle, we can set up the equation:<br/><br/>24 = (1/2) * x * 3x<br/><br/>48 = 3x^2<br/><br/>16 = x^2<br/><br/>x = 4<br/><br/>So, the shorter leg of the triangle is 4 feet.<br/><br/>To find the length of the longest side, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. In this case, the longest side is the hypotenuse.<br/><br/>Let's denote the length of the longest side (hypotenuse) as c.<br/><br/>Using the Pythagorean theorem, we can set up the equation:<br/><br/>c^2 = (4^2) + (3(4))^2<br/><br/>c^2 = 16 + 144<br/><br/>c^2 = 160<br/><br/>c = √160<br/><br/>c ≈ 12.6<br/><br/>So, the length of the longest side (hypotenuse) is approximately 12.6 feet.<br/><br/>Therefore, the correct answer is B) 12.6.
Q8If 60% of individuals possess a pet, with two-thirds of these pets being cats, what fraction of the population owns a cat?
Show answer
✓ Correct answer: 2/5
To determine the fraction of the population that owns a cat, we need to multiply the percentage of individuals that possess a pet (60%) by the fraction of these pets that are cats (2/3).<br/><br/>60% × 2/3 = (60/100) × 2/3 = 120/300 = 2/5<br/><br/>Therefore, the fraction of the population that owns a cat is 2/5.
Q9A waitress typically receives an average tip equivalent to 12% of the total cost of the food she serves. If she serves food amounting to $375 in one evening, how much would she earn in tips on average?
Show answer
✓ Correct answer: $45
Explanation:<br/>To calculate the amount of tips, multiply the total spent on drinks, which is 375, by the tip percentage of 12%. $375 × 0.12 = $45.
Q10With what number must 3.475817 be multiplied in order to obtain the number 34,758.17?
Show answer
✓ Correct answer: 10,000
The decimal must be moved four places to the right. To do this, we must multiply by a number with four zeroes.
