Answer:
1) I believe the answer is D
Explanation: The square root of 7 is approximately 2.64 which then gets divided by 3 which results in approximately 0.88, then you have to factor in that the problem has only one negative sign; therefore, the answer should be Point D.
Step-by-step explanation:
For the second one turn them into decimals
5/8 = 0.625
2√5 = 4.472
-pi/3 = -1.047
Then rearrange them 2√5, 5/8, -pi/3
A acute triangle looks like this..^^
8am : -14F
noon : -14+10 = -4F
increase between noon and 4 is 2*10 =20
4 pm: -4F + 20 = 16F
temperature at 4 pm is 16F
not b or c
