Answer:
To solve this problem you can divide the figure is known figures that have exact formulas for calculate their areas. As you can see in the figure attached, you can divide in two trapezoids, one rectangle and two right triangles. Therefore, you have:
Area=((4+3)6)/2+((6+3)5)/2+(3x1)+(3x4)/2+(3x3)/2
Area=21+22.5+3+6+4.5
Area=57
The answer is: The area is 57
Are you serious? oh well..
ok, draw a circle. devide the circle into 5 parts. color in 3 of the parts.
Now, draw 4 more of these.
Now, count the pieces.
Answer:
14
Step-by-step explanation:
All you need to do is turn 70% into a decimal which is .70
Then multiply .70 and 20
.70*20
which gives you 14
Answer:
60%
Step-by-step explanation:
You can solve this problem by setting up a system of equations.
Let's say that the number of tickets bought by students in the first year is x, and the number bought by continuing students is y. From there, you can set it up like this:
0.4x+0.2y=160
x+y=500
Now, you can multiply the first equation by 5 on both sides to get:
2x+y=800
Subtracting the second equation from the first equation now yields:
x=300
y=200
Since 300 of the 500 tickets bought were from the first year students, and 300/500 is 0.6, 60% of the students who bought the ticket were first year students. Hope this helps!
Didn't you mean "Find the possible value or values of z? y is not at all present in this equation.
z^2 - 4z + 4 = 0 can be factored into (z-2)(z-2). Thus, the given equation has two equal, real solutions: z=2 and z=-2.
