Step-by-step explanation:
hello :
19=3s+4
19-4 = 3s+4-4
3s=15
s=15/3
s=5
Answer:
Cookies
Step-by-step explanation:
If all 96 cookies were evenly divided among 8 people, each would have gotten:
Each person = cookies
<u><em>But Cindy received fewer than what she should have received (12 cookies). So Cindy got:</em></u>
cookies
The annual returns will be calculated as follows:
a] Here we use the formula:
A=p(1+r/100)^n
A=future amount
p=principle
r=returns
n=time
We are given:
A=500, p=400, t=1
Plugging the values in the formula we obtain:
500=400(1+r)^1
simplifying and solving for r:
1.25=1+r
thus
r=1.25-1
r=0.25~25%
b] Using the formula above:
A=p(1+r/100)^n
A=2500+100=2600, p=2000, n=1 year
plugging the values in the equation we obtain:
2600=2000(1+r)^1
simplifying and solving for r we obtain:
2600/2000=1+r
1.3=1+r
hence
r=1.3-1
r=0.3~30%
Answer:
okay so you have to take the steps you learned in math and apply because this is actually hard and you just have to really take your time and annotate the exerpt
Step-by-step explanation:
Cos α =
Let α = 30° ; adj = 2 ; hyp = x
∴ cos 30° =
⇒ x =
x = 2.31
