Answer:
The main objective of including the usual care treatment in the experiment is to offer a baseline for determining the survival rates of infants who received cooling of the whole body. The experimenters incorporated the usual care treatment in the testing so that they could compare the outcomes of this treatment with the outcomes of the entire body cooling treatment.
With this assessment, the experimenters could evaluate that whether the cooling treatment exhibited more positive influences on the babies in comparison to the usual care.
Explanation:
Ans: 93
Explanation:
The following information is given in the question:
1) Total of 209 salads and drinks.
2) salads for $6.50 each and drinks for $2.00 each; and total revenue was <span>$836.50
Now let us assign variables to the following entities:
1) Salad = S
2) Drinks = D
From the information given above,
1. S + D = 209 (total number of salads and drinks) -- (A)
2. 6.50S + 2.0D = 836.50 (total revenue equation) -- (B)
From equation (A):
D = 209 - S
Substitute the above equation in (B)
(B) => 6.5S + 2(209 - S) = 836.5
=> 6.5S + 418 - 2S = 836.5
=> 4.5S = 418.5
=> S = 93
Ans: Salads sold that day = 93.

t = t₀ / 2
Explanation:
In this exercise we must use Newton's second law
F = m a
a = F / m
now we can use kinematics
as in object part of rest (v₀ = 0)
v =a t₀
t₀ = v / a
these results are with the first experiment
now repeat the experiment, but F = 2F₀
a = 2F₀ / m = 2 a₀
v = 2 a₀ t
t = v / 2a₀
t = t₀ / 2
Therefore I am I can t be your man’s so now subtract and add
