Step-by-step explanation:
Let the amount of work be x.
Daniel:
10 days = x
1 day = 
x
Father:
6 days = x
1 day = 
x
Together:
1 day = x + x
= 
x + 
x
= 
x
=

Answer:
18.50 times 3 equals 55.5, the answer is 55.50
Answer:
Step-by-step explanation:
V = l * w * h
27000ft3 = (2w) * w * 10ft
27000ft3 = 2w^2 * 10ft
2700 = 2w^2
1350 = w^2
W = 36.74
Let θ = m∡I
tan θ = 20/21
tan⁻¹ (20/21) = θ
θ ≈ 43.60° or if you need to round to another decimal point, plug the equation I put in bold into a calculator.
Answer:
8.5% interest rate
Step-by-step explanation:
Principle: $4000
Interest rate: x
Time : 5 years
4000( 5 ) ( x ) = Interest
4000x = 1700/5
4000x = 340
x = 0.085 or 8.5% interest rate
<em>Check:</em>
8.5% x 4000 x 5
= 340 x 5
= 1700
