A stadium has a section 15m in height,
1 answer:
Answer:
The stadium can holds 90 numbers of people.
Step-by-step explanation:
Given:- A stadium has a,
Height= 15 meter,
Length = 12 meter,
Width= 3 meter.
Per person air space requirement = 6 meter cube.
To find:- Number of people stadium can holds=?
Solution:-
Total air space of the stadium =
Total air space of the stadium =
-------------(given)
Total air space of the stadium = 540 cubic meter. -------------(1)
Now,
Number of people stadium can holds =
Number of people stadium can holds =
------------(from 1 and given)
Number of people stadium can holds = 90
Therefore the stadium can holds 90 numbers of people.

Answer: 6 snack bags.
Step-by-step explanation:
For this exercise it is important to remember the Greatest Common Divisor (GCD). This is defined as the largest positive intener by which you can divided evenly "n" numbers.
In this case, you know that Jane has 18 juice boxes, 24 bags of peanuts and 36 apples. Therefore, the steps are the following:
1. You need to descompose 18, 24 and 36 into their prime factors, as below:
2. Now you must choose the common ones with the smallest exponent and multiply them.
Then, you get:
Therefore, the greatest number of snack bags that Jane can make is: 6 snack bags.
A parabola is the graph of a quadratic function,
that is the graph of
, where a is not 0.
from a, b and c we can derive the following informations about the shape of a parabola:
if a>0, the parabola opens upwards.
if a<0, the parabola opens downwards.
Consider the discriminant
If D>0, the parabola intersects the x-axis at 2 points.
If D=0, the parabola intersects the x-axis at 1 point.
If D<0, the parabola does not intersect the x axis.
"<span>the vertex of a parabola is in the first quadrant and the parabola opens upwards.</span>"
the vertex is in the first quadrant means that the vertex is above the x-axis, and it opens upwards, so the parabola does not intersect the x-axis.
This means that:
Answer: a>0, the discriminant D<0
