Answer:
A. Five places to the left
Step-by-step explanation:
Scientific notation is a method used so we can show a very big/small number easier. Rather than putting so many zeroes, we put the number in the format of a number multiplied by 10^x.
Before putting a number into scientific notation, you need to know which number is a significant figures. In this question, there are two significant figure which is 39, all zeroes on the right is insignificant. We can move the decimal to convert the number into 3.9 * 10^5. Basically you need to move the decimal to the left if the exponent positive, but move it to the right if its negative. The exponent is +5 so we move the decimal points 5 places to the left.
The missing term of the sequence is 41
Answer:
Assume that 1900km^2 is 1900.
If that happens, The equation of that will look like...
1900 - (1900 x 7.75% x 14)%.
1900 x 7.75% are 147.25.
and 147.25 x 14 are 2061.5.
so... there will be no forest after 14 years.(harsh)

Answer:
48 cubes are needed to fill the prism
Step-by-step explanation:
To solve this problem we first have to calculate the volume of the cube
1/2 units= 0.5 units
To calculate the volume of a cube we have to use the following formula:
v = volume
s = side = 0.5 u
v = s * s * s
we replace the values that we know
v = 0.5 u * 0.5 u * 0.5 u
v = 0.125 u³
The volume of the cube prism is 0.125 u³
Now we have to divide the volume of the prism by the volume of the cubes
6 u³ / 0.125 u³ = 48
48 cubes are needed to fill the prism
