Yes it is. It is the only even number that is prime that is multiplied by 1.
Since they are similar, you need to find the ratio of similarity (I made up the term, there is probably a correct one that I can’t remember).
If you divide 16/40, you’ll find that that ratio is 2.5. So then you just multiply 16 x 2.5. You’ll get 18.
18 is the length of the top of the trapezoid.
You set 18=2x+4 and solve it algebraically. Subtract 4 from both sides.
14=2x
Divide by 2 and x=7
(You can also check that the ratio is right by 16/18 is the same decimal value as 40/45. You’ll get .88888...)
Answer:
5/9 cubic yards
Step-by-step explanation:
Just so L*W*H=24(36)(30)= 25920 cubic inches=25920 (1 in*1 in* 1 in)
36 in=1 yd
so
1 in =1/36 yd
do divide 25920 by (36*36*36)
The answer in cubic yards is 5/9 cubic yards
Plug in the values
3(5) - 5(1)
15 - 5 = 10
Solution: 10
