10% of 25,000 is 2500 so it would take him 25 months to have enough money for a down payment
A.) Here, w = 550kg/m^3.
Therefore, S = (0.032(550) - 2.5)/10000 = 0.00151
After drying, the beam will be (1 - 0.00151) x 12.027 = 12.009
b.) 0.0012 = (0.032w - 2.5)/10000
0.032w - 2.5 = 12
0.032w = 12 + 2.5 = 14.5
w = 14.5/0.032 = 453 kg/m^3
Therefore, the required water content is 453 kg/m^3
Answer:
∠ AFE = 80°
Step-by-step explanation:
Since BD is a straight line , then
∠ AFB + ∠ AFE + ∠ EFD = 180°, that is
50° + ∠ AFE + 50° = 180°
100° + ∠ AFE = 180° ( subtract 100° from both sides )
∠ AFE = 80°
So pretend weekend calls is x and weekday calls are y.
the formulas is x + y = 610
0.07x + 0.08y = 48.05
So, x = 610 - y
Then, substitute x into the second equation.
0.07(610 - y) + 0.08y = 48.05
42.7 - 0.07y + 0.08y = 48.05
0.01y = 5.35
y = 535
Then substitute y into the first equation.
x + 535 = 610
x = 75
Just to be sure, substitute x and y into the second equation.
0.07(75) + 0.08(535) = 48.05
5.25 + 42.80 = 48.05
48.05 = 48.05
So, on weekends, he used 75 minutes.
On weekdays, he used 535 minutes.
