Answer:
4/9
Step-by-step explanation:
The scale factor for the linear dimensions of the ball bearings will be the cube root of the volume scale factor:
k = ∛(1.6/5.4) = 2/3
Then the scale factor for the areas will be the square of this scale factor:
ratio of surface area = (2/3)² = 4/9
_____
The area is the product of two linear dimensions, so its scale factor is the product of the linear dimension scale factors. That is, the scale factor for area is the square of the linear dimension scale factor.
Similarly, volume is the product of three linear dimensions, so its scale factor is the cube of the linear dimension scale factor.
Answer:
<h2>Slope =1</h2>
Step-by-step explanation:
Method 1 : Standard form method
Method 2 : Slope -intercept Form
This is based off this year so 1990-2017
Since there are 27 years it would be 2300*27 which would equal 62,100 people
The new births would be 375,000(1.013)^27 which would equal 531,479 people
Adding 531,479 with 62,100 equals 593,579 people
multiply number of pieces by size to find how much she has:
8 x 6.2 = 49.6 feet
Subtract what she has from what she needs to find how much more she has to get:
90-49.6 = 40.4 feet more
