Answer:
f(n+1) = f(n) - 5
Step-by-step explanation:
Just find some relationship between 2 numbers that are next to each other.
Answer:
-23/18
Step-by-step explanation:
-7/9 = -70/90
-5/10 = -45/90
-70-45 = -115
-115/90
-23/18
EDIT: whoops, I subtracted 45 from 70 instead of adding them. it should be correct now.
hope this helps, goodluck with your schoolwork/homework.
sorry for any errors or bad explanations.
Easiest way to work it out is to divide by ten, that gives 10% of your original number. Multiply that by two to get 20% and minus that from the original number to get the discount.
450/10 = 45 which is 10% of 450.
20% of 450= 10% x 2 or 45 x 2
therefor 20% of 450 is 90.
450-90 = the discount the shoppers recieve.
4x is the proportionality
Find the surface area of the <em>two green cubes</em> first, 2x2 = 4 square centimeter ((each)).
Next find the surface area of the <em>blue rectangular prism</em>, 11 x 5 x 5 = 275 square centimeters.
Now add the the surface areas of the cubes and rectangular prism to find the total <em>area</em> <em>of the</em> <em>figure</em>,
4 + 4 + 275 = 283 square centimeters.
