Answer:
B. Perimeter of a square and
C. Side length of a square
Step-by-step explanation:
if n= side length of square then
- Area of square is

- Perimeter of a square is 4×n
- diagonal length of a square is
× n
Thus,
Perimeter of square can be expressed as
×diagonal length of a square
Side length of a square can be expressed as
×diagonal length of a square
but Area of square is
×n×diagonal length of a square
As a Result, Area of square is <em>also dependent of the value n</em>, wheras in other cases it is <em>a proportion of diagonal length of a square</em>
Standard Form: 79,031
Expanded Form: 70,000 + 9,000 + 30 + 1
Keep note of these things before we start:
-Of is a keyword that tells us multiplication is being done
-x = total number of pages
-32% = 32/100 = .32
Okay, here we go:
32% of total number of pages = 80
.32 of x = 80
.32*x = 80
.32x = 80
.32x/.32 = 80/.32
x = 250
There are 250 pages in total in Katie's book.
To find out how many pages she has to read (y), subtract the pages read from the total:
TOTAL - PAGES READ = PAGES LEFT TO READ
250 - 80 = y
170 = y
Katie has 170 pages left to read
Hope this helps!
Answer:
190 baskets of strawberries
Step-by-step explanation:
The question is incomplete as it didn't state what we are to determine from the information given.
Let's determine total amount picked in the three days.
1st day picked 90strawberries
Amount of strawberries on 2nd day = 2/3 of the amount picked 1st day
= (2/3)(90)
Amount of strawberries on 2nd day = 60 baskets of strawberries
Amount of strawberries picked on 3rd day = (2/3) of the amount picked 2nd day
= (2/3) (60)
Amount of strawberries picked on 3rd day = 40 basket of strawberries
Total amount picked for 3 days = 90+60+40
= 190 baskets of strawberries
