Answer:
280 ft squared
Step-by-step explanation:
To find the area of the nonshaded portion, we can find the area of the entire floor and then subtract the shaded area.
The total area is that of a rectangle: 30 * 15 = 450 ft squared.
Now, the shaded region is made up of a rectangle and a triangle.
- The rectangle has length 8 and width 10, so its area is 10 * 8 = 80 ft squared.
- The triangle has base 12 and height 15, so using the area of a triangle formula: 
(where b is the base and h is the height) = (12 * 15)/2 = 180/2 = 90 ft squared.
- The total shaded region is: 80 + 90 = 170 ft squared
Subtract 110 from 450: 450 - 170 = 280 ft squared.
Thus, the answer is 280 ft squared.
Hope this helps!
You divide both numbers by their largest common factor, which is 5 in this case.
15(/5):5(/5)
3:1
If she needs 8 cups of flower for 4 eggs, when you could change that to needing 4 cups of flower for 2 eggs, now we know every 4 cups of flower is 2 eggs, and we already know 8 cups of flower is 4 eggs, so if we add 2 more eggs and that means 4 more cups of flower, the final answer is: 12 cups of flour is 6 eggs. To make it easier to remember, just remember if you have even numbers you can split them into pieces and just add those pieces over and over until you get it. We started with 8 cups of flour is four eggs, and if you put it to its smallest part It would be 4 cups of flower for 2 eggs, then you just have to remember how to count your 4’s and 2’s and it’s as easy as that
Answer:
Domain: all real numbers
The interval on which the function is increasing is : (0 , infinity)
The interval on which the function is decreasing is : (-infinity , 0)
The interval on which the function is constant is : ( 0,0 )
Step-by-step explanation:
f(r)=5r^2−4
This is a quadratic function.
vertex at (0, -4) and with positive coefficient for r^2
