First we need the area of the whole shape (A=l*w)
A:A=7*5 or 35 (7 because you add 3 and 4)
B:A=3*4 or 12
C:A=4*4 or 16
D:A=3*9 or 27 (9 because you add 5 and 4)
So the whole area is 35+12+16+27 = 90
Then we do the part divided by the whole to find probability
=27/90 which can be simplified to 3/10
Hope this helps
Step-by-step explanation:
Find the values of x and y to determine how many solutions.
Use the elimination method. Add both of the equations.
<u>Sum:</u>
<u />
<u>Divide each side by 3:</u>
<u />
<u />
<u>Substitute y = -(1/3) into the first equation:</u>
<u />
<u>Multiply:</u>
<u />
<u>Add 2 to both sides:</u>
-5x = 0
We can determine:
(0, -1/3)
The system of equations have 1 solution.

Answer:
Option A is correct.
Step-by-step explanation:
Given an isosceles trapezoid has base angles of 45° and bases of lengths 8 and 14. we have to find the area of isosceles trapezoid.
An isosceles trapezoid has base angles of 45° and bases of lengths 8 and 14.
From the figure attached , we can see an isosceles trapezoid ABCD,
AB = 8cm and CD=14cm
So we have to find the value of AE which is the height of Trapezoid in order to find area.
In ΔAED
⇒
∴ AE = DE =3cm
h=3cm, a=14cm, b=8cm
hence,
Option A is correct.
