Yes it is Direct Variation. Y/X=8
*X *X
Y=8X
To find the unit rate you need to take the amount and divide it by the weight. In this case 2.99/14 = $0.214/lb
Answer:
I don't know
Step-by-step explanation:
could you screenshot your question or reword it. I don't know what you're asking. Sorry.
Newton's law of cooling is
k (t₁ - t₂) = -ln (T₁ - T∞ / T₂ - T<span>∞)
Use the two data points in the given to find k.
t = 0, T = 154
t = 10, T = 133
Solution:
k(0 - 10) = - ln (154 - 71/ 133 - 71)
-10k = -0.291716
k = 0.02917 or 0.0292
So now find t when T = 100
0.2917 * ( 0 - t) = -ln (154 - 71 / 100 -71)
- 0.02917t = - 1.0515
t = 36. 05 minutes
to the nearest minute t = 36</span>
Answer:
Consider polygon G as a triangle or any quadrilateral, pentagon, Hexagon, Heptagon, Decagon,....
Now Polygon H is scaled copy of Polygon G by a scale factor of 1/4, it means
If the length of sides of triangle are a,b,c then scaled copy of triangle by using
1/4 means the new sides of polygon which is triangle will be a/4,b/4,c/4.
For example consider a parallelogram having sides 12 cm and 8 cm respectively.The scaled copy of parallelogram by a scale factor of 1/4 will be of length 1/4×12,1/4×8 which is parallelogram having sides 3 cm and 2 cm respectively.
