Each tube costs $2.25
24.95-6.95=18
18/8=2.25
a. 1.732
because if the number behind the number you are rounding is 5 or greater, you go up a number, but if it is less than 5, then you leave it the same. this applies to both problems.
b. 3.142
Answer:
2.65secs
Step-by-step explanation:
Give:
The function h(t)=−16t(t−7) models
the object will hit the ground at h= 0
h(t)=−16t(t−7)
0= -16t(t−7)
0= -16t^2 + 112
16t^2 = 112
t^2 = 7
t= √7
t=2.65secs
Hence, the object object hit the ground at 2.65secs

Answer:
(b) ... confirm ∠C≅∠E
Step-by-step explanation:
The first step is to read and understand the problem statement. It is asking for a way to prove ΔABC ~ ΔADE by AA similarity. That means you want to show any two of the three ...
For this purpose, lengths of line segments are irrelevant (eliminating the last two answer choices). The fact that ∠A≅∠A is given, so you only need to find an answer choice that will show one of the last two angle congruences.
Obviously, showing ∠B≅∠E (choice A) is not relevant to the problem.
The only answer choice that is relevant to the question is the second one, showing ∠C≅∠E.
