To begin, each of the friends have made 4 bags of dough. This gives 12 bags at the outset. After 10 days, all 12 bags are made into (4*12) bags, or 48 bags. After 20 days, the 48 bags are made into (48*4), or the required 192 bags. After 20 days, then, the friends have the needed 192 bags.

Answer:
31/-45
Step-by-step explanation:
rise is 31(-8 to 23) and run is -45 since you are going from 30 to -15
Answer:
7.9km
Step-by-step explanation:
(a)See attached for the diagram representing this situation.
(b)
In Triangle ABC

Next, we determine the value of Angle B.

Finally, we find b.

The distance between the small plane and the observation tower is 7.9km.
P=2(l+w)
50=2(4+w)
50=8+2w
collect the like terms 50-8=2w
42=2w divide both sides by 2
w=21

<h3>Answer = -7</h3>
════════════════════
<h3>Known</h3>
a = 13
U2 = 6
U3 = -1
U4 = -8
════════════════════
<h3>Question</h3>
d = ..?
════════════════════
<h3>Way to do </h3>
#since it gives a lot of number, i will just pick one of the nth term, ill choose U2
Un = a + (n-1)d
U2 = 13 + (2-1)d
6 = 13 + d
6 - 13 = d
d = -7
════════════════════
<h3>Note</h3>
• The formula of arithmetic sequence
<h2>Un = a + (n-1)d</h2>
n = nth term
a = first term
d = common difference
