Answer:
18 feet
Step-by-step explanation:
Perimeter=2(l+b)
80=2(w+w+4)
80=2(2w+4)
80=4w+8
80-8=4w
72/4=w
W=18 feet
To solve this, I will use proportions:
The defected ones have a proportion of 1:400
So just make this proportion:
Once you solve it, you get a value of
5
Answer:
11/24
Step-by-step explanation:
First find the common denominators of each fraction:
The common denominator of each fraction is 24
- 1/8 multiplied by 3 is 3/24
- 1/6 multiplied by 4 is 4/24
- 1/4 multiplied my 6 is 6/24
add these fractions up
3/24 + 4/24 + 6/24 = 13/24
subtract 24/24 - 13/24 = 11/24
Answer:
<u>For this problem we have:</u>
- Initial value P = $5131
- Increase rate r = 8% or 0.08
- Time 20 years ago t = -20
- 30 years ago t = -30
<u>Find the value of F using the formula and substitute the values:</u>
- F(-20) = 5131(1 + 0.08)^(-20) = 1100.84685219 ≈ $1101
and
- F(-30) = 5131(1 + 0.08)^(-30) = 509.905093313 ≈ $510
8c+6-2
11c+6-2
Add 2 to 6
you will get 8
D. 11c+8
