It would be 7 x 28 x 1/2 I think
Answer:
12
Step-by-step explanation:
If there are 3 classrooms that each have 25 desks and there are a total of 87 students, how many more desks need to be added to a 4th classroom, that was originally empty, so that each of the students has a desk to sit in?
25 * 3 = 75
87 - 75 = 12
Answer:
it's E
Step-by-step explanation:
(5x+y)²
You expand the bracket
it gives;
(5x + y)(5x+y)
Now, multiply 5x by 5x=25x²
multiply 5x by y= 5xy
multiply y by 5x=5xy
multiply y by y=y²
Bringing into an equation it gives;
25x²+5xy+5xy+y²
=25x²+10xy+y²
P >= 430, because the pool has 430 people in there at the moment and we can assume that it is full or it has more space for more people, so p will equal 430 or greater.
If you would like to know the total value of the liquid in the container, you can calculate it using the following steps:
A cone:
a radius (r) ... 1 in.
a diameter ... 2 in.
a height (h) ... 9 in.
<span>π ... 3.14
</span>
Cone volume formula:
V = 1/3 * π * r^2 * h
V = 1/3 * 3.14 * 1^2 * 9 = 1/3 * 3.14 * 1 * 9
V = 9.42 cubic inches
$2 ... 1 cubic inch
$x = ? ... 9.42 cubic inches
_______________________
2 * 9.42 = 1 * x
x = 2 * 9.42
x = $18.84
The correct result would be $18.84.
