Answer:
-1 1/5
Step-by-step explanation:
<em>Change the whole number 4 to an improper fraction</em>
-4 4/5 ÷ 4/1 = -4 4/5 ÷ 4/1
<em>Reciprocal the 4/1 will become 1/4 then go to multiplication</em>
-4 4/5 ÷ 4/1 = -4 4/5 × 1/4
<em>Change to improper fraction the -4 4/5</em>
-4 4/5 ÷ 4/1 = -24/5 × 1/4
<em>Then simply multiply the two numerators and the two denominators</em>
-4 4/5 ÷ 4/1 = -24/20
<em>Finally, Simplify it to get the answer</em>
-4 4/5 ÷ 4/1 = -1 1/5
I did the calculations of A(t)=50(0.8)5
and i got 200 for the 50*0.8*5
and the A(t) is 1,000
Hope i could help :D
Answer: Let length = 2x + 3
Let width = x
Area = 54 ft2
length × width = Area
x(2x + 3) = 54
2x2 + 3x = 54
2x2 + 3x - 54 = 0
(2x - 9)(x + 6) = 0
x = 9/2 and x = -6
x = 4.5 and x = -6
We accept x = 4.5 because length cannot be a negative value. Substituting this value into the dimensions:
width = 4.5 ft
length = 2(4.5) + 3 = 9 + 3 = 12 ft
