<h2>The answer is

.</h2>
Step-by-step explanation:
Let the building contractor bought 1000 cement in total.
70% of 1000 = 700 cements were from A and (1000 - 700) = 300 cements were from B.
The number of undamaged bag from A was 95% of 700 =
and the number of undamaged bags from B was 70% of 300 =
.
Total undamaged bags were (665 + 210) = 870.
The probability that an undamaged bag is from A is
.
Answer:
155
Step-by-step explanation:
calculate the areas of 2 rectangles
method A
one rectangle with lengths 8 and 10
the other 15 and 5
so 8x10 + 15x5 = 80 + 75 = 155
method B
one traingle with lenghts 5 and 7
the other 15 and 8
so 15x8 + 5x7 = 120 + 35 = 155

Step-by-step explanation:
Given volume and depth respectively,
and 
To find length and width of the rectanglular swiming pool we know,
Volume=length
height
depth.
Let depth=D=x-3, length=L, width=W, then



After divide we will get
with remainder -144.
Thus,

Now to find root of,

Thus,


Step-by-step explanation:
since they are angles and there are three of them. Assume that they are part of a triangle. That is all I can do until you give more information about the problem. lmk down in the comments on the side length or whatever the problems asks for.
have a good day :)
