Hello :
let : x the length and y the <span>width
the perimeter is : 2(x+y)
2(x+y) = 70 and : x/y =4/5
x+y = 35 ......(1)
x = (4/5)y ... (2)
subsct in : (1)
</span> (4/5)y +y = 35
4y+5y = 175
9y = 175
y = 175/9
in (2) : x = (4/5)(175/9) = 140/9
It is a acute triangles because the degrees are less than 90 degrees
Answer:
The number of construction workers is the independent variable.
Step-by-step explanation:
The time it takes to finish the building depends on how many people work on it. So, the time it takes is the dependent variable, which depends on how many people work on it, which is the independent variable.
The formula is
A=p (1+r/k)^kt
A future value?
P present value 120
R interest rate 0.86
K compounded monthly 12
T time 21 year
A=120×(1+0.86÷12)^(12×21)
A=4,510,568,953.1372
Answer:
yeah, well y=x/r-s
