Answer:
2.988*10^8
Step-by-step explanation:
to do standard form you have to move the decimal to after the first number so in this case we would move the decimal 8 places from 298800000.0
to 2.98800000 and we can remove the zeros to make it 2.988
then you will plug the times ten and because we move the decimal over 8 it would be 10 to the power of 8 so your answer would be 2.988*10^8
hope this helps have a good day

Answer:
Width of rectangle = 6 m
Length of rectangle = 11 m
Step-by-step explanation:
Let width of rectangle = w
Length of rectangle = 3w-7
Area of rectangle = 66 m²
We need to find length and width of rectangle
The formula used is: 
Putting values and finding w
Solve using quadratic formula: 
We have a=3, b=-7, c=-66
Putting values and finding w
We get values of w as w=6 and w=-3.6
As we know width cannot be negative, so considering w = 6
So, Width = 6
Length = 3w-7 = 3(6)-7 = 18-7 = 11
So, Width of rectangle = 6 m
Length of rectangle = 11 m
Y directly proportional to WX and inversely to Z.
Y=k(WX)/Z
Where k is the constant of proportionality.
So, the first thing is to find the value of this constant.
k = YZ/WX
= (32×3)/(6×20)
= 96/120
= 0.8
The <span>equation that models the relationship will be;
Y = 0.8(WX/Z)</span>
D=t/3
12=t/3
×3 ×3
___________
36=t
So the answer is D.) 36 kilometers
Answer:
The answer is 2
Explanation:
The lowest number that can eliminate the fractions would be 2. And it fits all of them since they are factors of 2.
