Answer:
The inequality is : "x < 23" which agrees with answer "D" in your list
Step-by-step explanation:
Notice that the number of cookies that Susan bakes is the unknown "x".
Since her sister bakes 24 more cookies than what susan does, then the sister makes:
Sister = x + 24
Let's now write the number of cookies that both bake which should be the addition of both quantities: x (what Susan bakes) plus "x+24" (what her sister makes): x + x + 24 = 2 x + 24
Now we write in math terms that this expression should be less (<) than 70 - Notice that the problem says "less than 7", and not "less than or equal 7", so the strictly less than symbol applies:
2 x + 24 < 70
and work to isolate "x" on one side of the inequality, by first subtracting 24 from both sides:
2 x < 70 - 24
2 x < 46
and then dividing both sides by "2" to leave just "x" on the left:
2 x / 2 < 46 / 2
x < 23
Answer:
1/1/3 is the answer “ one and one third
Step-by-step explanation:
to find length scale factor,
take the length of the 2nd triangle and divide it by the length of the first triangle,
you'll get the length scale factor
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>
