Answer:
5% or 0.05
Step-by-step explanation:
Diana invested $3000 in savings account 3 years. And the total interest gained by Diana is $450. Therefore,
Principal amount (P) = $3000
Time (t) = 3 years
Total interest (I) = $450
Rate (r) =r
Using the formula,
I =
450 =
45000 = 9000×r
r =
=5%
r = 0.05
Hence, the interest rate = 0.05
Answer:
15) 2.08m
Step-by-step explanation:
We kow tanA= p/b
Here, A=33°
b=3.2m
Then,
tan33°=p/3.2
0.65=p/3.2
p=0.65*3.2
p=2.08
So, The height of tree is 2.08m
14) 59.58ft
tan50°=p/b
1.19=p/50
p=59.58ft
So, The height of signpost is 59.58ft
Area of a parallelogram is A = base times height
Area = 15 * 13 = 195
So, your answer is 195 cm squared

Answer:
Width: 160
Length: 80
Step-by-step explanation:
Width = 2x and length = x
X + 0.5x + 2x - 0.4x = 248
3.1x = 248
X = 248/3.1
X = 80
Width = (2)(80) and length = 80
