Answer:
- D. The experimental data does not support Sally’s hypothesis.
Step-by-step explanation:
<u>Sally's hypothesis can be shown as:</u>
- 8c = 1p, where c- coil, p- paper clip
<u>From the data in the table we can see that:</u>
- 8c = 2p ⇒ 4c = 1p
- 16c = 4p ⇒ 4c = 1p
- 24c = 6p ⇒ 4c = 1p
As we see there is a difference, Sally can pick up one paper clip for each 4 coils.
Correct answer choice is D.
The answer is C, they are congruent because they are alternate interior angles
Answer is in the sheet, hope this helps!
For this case we have the following compound inequality:
11 <7 + 0.25t ≤ 15
We must solve this inequality for time.
We have then:
For 11 <7 + 0.25t:
11 <7 + 0.25t
11 - 7 <0.25t
4 <0.25t
4 / 0.25 <t
16 <t
For 7 + 0.25t ≤ 15:
7 + 0.25t ≤ 15
0.25t ≤ 15 - 7
0.25t ≤ 8
t ≤ 8 / 0.25
t ≤ 32
Therefore, the answer is:
16 <t ≤ 32
Answer:
16 <t ≤ 32
Clara has the desired length in more than 16 weeks, but up to 32 weeks.
Answer:
The symphonic choir can record a maximum of 14 songs.
Step-by-step explanation:
We know that the album cannot be more than 72 minutes long, and the jazz choir records a total of
song minutes.
If we call
the number of songs the symphonic choir records , and each song is 3.5 minute long, then the song minutes for the symphonic choir are
; therefore, we have the inequality
<em> (this says the song minutes for jazz choir plus song minutes for symphonic choice cannot exceed 72 minutes )</em>
We solve this inequality by subtracting 21 from both sides and then dividing by 3.5:



The maximum integer value
can take is 14; therefore, the maximum number of songs the symphonic choir can record is 14 songs.
