Math Video Questions
- Karla loves Social Media and is always ignoring her assignments, so for every assignment she completes she gets a certain amount of time on Social Media. The proportion between assignments, x, and hours on Social Media, y, is for every 3 assignments complete she gets 45 minutes on Social Media. Write an equation of proportional relationships between x and y. (x= assignments, y= Time on Social Media)
- Karla’s sister, Olivia, also loves Social Media and is always ignoring her assignments too, but her proportions are different than Karla’s. The proportions for Olivia are for every 2 assignments, x, she gets 10 minutes, y, on Social Media. Write an equation of proportional relationships between x and y. (x= assignments, y= Time on Social Media)
- What is the least amount of assignments that Olivia and Karla both need to individually complete to have the same amount of time on Social Media?
- Marcia wants to estimate the total weight of the sand in her sandbox. She has a drinking glass whose interior is a cylinder with diameter 2 inches and height 4 inches; the glass weighs 4.1 ounces when empty. After she fills the glass with sand, the weight of the glass is 14.8 ounces. If the sandbox is a rectangle measuring 6 feet by 4 feet, and the average depth of the sand is 6 inches, what is the total weight of the sand in the sandbox in pounds? Express your answer as a whole number to the nearest hundred. (1 foot = 12 inches; 1 pound = 16 ounces.)
