#1: 7000 + 500 + 2
#2: 7000 + 502
#3: 750 + 2
#4: 7452 + 50 = 7502
#5: 7502 x 1 = 7502
#6: 10000 - 2498 = 7502
#7: 7508 - 6 = 7502
#8: (7502 x 0) + 7502

Answer:
One example of an equivalent ratio to 3/30 is 1:10.
Answer:
33.33 mL of 50%
66.67 of 80%
Step-by-step explanation:
Let x = quantity of 50% methane.
Then,
0.50x + 0.80(100 - x) = 100 × 0.70
⇒ 0.50 x + 80 - 0.80 x = 70
⇒ -0.30 x = 70 - 80
⇒ -0.30 x = -10
⇒ 
⇒ x = 33.33 mL of 50%
and, 100 - 33.33 = 66.67 of 80%
Answer:
Hi There!
Your answer is:
<u>Length = 116</u>
<u>Width = 56</u>
Step-by-step explanation:
L= 4+ 2w
Width=w
perimeter formula
l+l+w+w= perimeter
Subsitute L for 4+2w
(4+2w)+(4+2w) + (w) + (w) = 344
8 +4w+w+w = 344
8+ 6w = 344
-8
6w = 336
/6
w= 56
PLUG BACK IN!
Length = 4+ 2w
Length = 4+ 2(56)
<u>Length = 116</u>
<u>Width = 56</u>
CHECK YOUR WORK
116+116+56+56= 344???
344 = 344 YES
