Answer:

20.99+ 10.29n s 100

Step-by-step explanation:

Well your variable is the number of pants she wants to buy, so on top of the shirt she bought it would 20.99 + 10.29n, but you wouldn't put 100$ at the end of the sentence because for all you know she could have gone past 100 dollars. Hope this helps! Also, if we are counting this from 100 it is better to just subtract 20.99 from 100 and divide by 10.29.

A forensic detective is called to the scene of a murder at 2 am. When she checks the temperature of the body, she sees that it i

Readme [11.4K]

Newton's Law of cooling is
$T(t)=T_{a}+(T_{0}-T_{a})e^{-0.1947t}$
where
T(t) = temperature of the body after t hours, 80 °F
$T_{a}$ = ambient temperature, 65 °F
$T_{0}$ = normal body temperature, assumed to be 98.6 °F

The elapsed time since death is obtained from
$65+(98.6-65)e^{-0.1947t|} = 80$
$33.6e^{-0.1957t}=15$
$-0.1947t=ln \frac{15}{33.6}$
$t= \frac{ln(15/33.6)}{-0.1947} =4.142$

4.142 hours before 2 am is 9:52 pm (the previous day) approximately.

Answer: 9:52 pm the previous day.

2 questions correct anwser gets brainlyess

Vlada [557]

Answer:

Question 1: x=55
Question 2: m∠A=45°

Step-by-step explanation:

<u>Question #1</u>

- Since it is an isosceles triangle, this means that the base angles have the same value.

- The angle sum is 180°

Solve

2x+35+35=180

2x+70=180

2x=110

x=55

<u>Question #2</u>

- Since it is given there is a right angle, this means the angle is 90°

- The angle sum is 180°

Solve

5x+5x+90=180

10x+90=180

10x=90

x=9

It asked to find m∠A, which is 5x. So 5x=5(9)=45°

Hope this helps!! :)
