Answer:
1/2
Step-by-step explanation:
There are a total of 25 students. 3 don't study art or biology. 10 study only biology. 6 study both art and biology. This means the remaining students only study art.
1. Calculate the number of students taking art
only art: 25 - 3 - 6 - 10 = 6
number of students taking art and biology: 6
total number of students taking art: 12
2. Calculate the probability
Out of the 12 total students taking art, 6 are in art and biology.
6/12 = 1/2
The figures that can have a triangle as a two-dimensional cross section are (4) I, III, and IV, only
<h3>How to determine the figures?</h3>
The cross-section of three-dimensional figures are as a result of slicing the figure along its axis.
- When the cube is sliced with its plane, it gives a triangle face
- When a cone is sliced vertically, it gives a triangle face
- One of the faces of a square pyramid is a triangle; so it has a triangle face
Hence, the figures that can have a triangle as a two-dimensional cross section are (4) I, III, and IV, only

Answer:
<em>Hence, it will take</em><em> 9 seconds </em><em>for kirk to run </em><em>63+9=72 yards </em><em>and catch upto Max. </em>
Step-by-step explanation:
Let 'y' represents the time Max and Kirk took to meet.
Let the distance between the destination where they will meet from the place where Max is be: x yards
So the distance of destination from initial position of kirk is x+9 yards ( As Max is given a head start of 9 yards)
- As speed of Max is 7 yards per sec.
And 
Hence,
- also speed of kirk is 8 yards per second.
By the similar definition of speed we have:
Hence (1) and (2) are the required system of equation.
So on solving the system of equations by elimination method we have:
y=9 and x=63.
Hence, it will take 9 seconds for kirk to run 63+9=72 yards and catch upto Max.
Hello!
To solve this you have to do 15 + 6 because Shari saw 6 more birds than Morgan
The answer is 21 birds
Hope this helps!
