Answer:
C. 2, -1, -5, -8.
Step-by-step explanation:
a = first term = 2
second term, a2n-1) - 3 = 2 - 3 = -1
third term = -2 - 3 = -5
fourth term = -5 - 3 = -8.
Applying the law of sines, the measurement indicated are:
7. AB = 24.1 cm
8. BC = 28.0 in.
<h3>What is the Law of Sines?</h3>
Law of sines is: sin A/a = sin B/b = sin C/c.
7. AB (c) = ?
BC (a) = 22 cm
A = 180 - 138 - 22 = 20°
C = 22°
Apply the law of sines:
sin 22/AB = sin 20/22
AB = (sin 22 × 22)/sin 20
AB = 24.1 cm
8. BC (a) = ?
A = 58°
AC (b) = 33 in.
B = 180 - 58 - 33 = 89°
Apply the law of sines:
sin 58/BC = sin 89/33
BC = (sin 58 × 33)/sin 89
BC = 28.0 in.

Answer:
We must solve 3/5 x 3/5.
3/5 x 3/5 = 0.36
The units we'll use is because units are the unt we're given, and it is squared because it is the area of a shape.
Your final answer is 0.36
Answer: 49
Step-by-step explanation:
If 72% of the stamps he collected were
foreign, the percentage of the other stamps will be: = (100% - 72%) = 28%
Since the total number of stamps collected are 175, the number of other stamps collected will be:
= 28% of 175
= 28% × 175
= 28/100 × 175
= 0.28 × 175
= 49
Therefore, he collected 49 other stamps that were not foreign
Answer:
x≤3
Step-by-step explanation:
Since you can't get any more than 3 flash drives, the inequality is (making x=the number of USB flash drives you can buy):
x≤3
