katie has read 32% of a book. if she has read 80 pages, how many more pages does katie have left to read

Answers

x=total number of pages.
1)we calculate the total number of pages.
32% of x =80
(32/100)x=80
x=(80*100)/32
x=250.

2) we calculate the number of pages don´t read.
number of pages don´t read=250-80=170 

Answer: 170 pages. 


80/32% or 80/.32=250. 250-80=170 :)

What is the surface area of the rectangular prism?125 m2

200 m2

250 m2

Answers

Answer:

Surface area =250 m^2

Step-by-step explanation:

Given the length of the prism is 10m

width is 5m and height is 5m

The formula for surface area =

2(length times width)+2(width times height)+2(height times length)

Plug in all the values in the formula

Surface area =2(10 \cdot 5) +2(5 \cdot 5)+2(5 \cdot 10)

=100+50+100=250

Surface area =250 m^2

\n$Surface area of a rectangular prism = The sum of the areas of the 6 rectangles formed by the height length and width.\n$S_A = 2(5^2 + 5\cdot 10 + 5\cdot 10) = 250m^2

The orchard needs to fills n order for 156 apples using both large and small bags. What is the least number of each type of bag that could be used if each bag is completely filled?

Answers

I find a similar question that looks like this:
The apples can be packed into a large bag that holds 9 apples or a small bag that holds 6 apples. The orchard needs to fill an order for 156 apples using both large and small bags. What is the least number of each type of bag that could be used if each bag is completely filled?

The correct answer for the question that is being presented above is this one: 
Given is 16 large bags and 2 small bags.

16 * 9 =144

2 * 6 = 12

144 + 12 = 156
