Answer:
10
Step-by-step explanation:
5x+37=87
5x=87-37
5x=50
X=50÷5
X=10
The value of the angle θ required in the water main for the turn from north to east is 87.40°.
According to the statement
We have to find that the value of the angle.
So, For this purpose, we know that the
An angle is created when two straight lines or rays meet at a standard endpoint.
From the given information:
a main is to be constructed with a 20% grade within the north direction and a tenth grade within the east direction.
Then
Let n = North
and e = east
Then
using vectors,
n = j + 0.20 k
e = i + 0.25 k
And the
n · e = 1x0 + 0x1 + 0.20×0.25 = 0.05
Now take magnitude then
|n|·|e| = i(1² + 0.20²)·i(1²+0.25²) = 1.105
Now,
E° = arccos((n · e)/|n|·|e|)
E° = arccos(0.05/1.105)
E° = arccos (0.0452)
E° = 87.40°
So, The value of the angle θ required in the water main for the turn from north to east is 87.40°.

Answer:
111 mg (to the nearest whole number)
Step-by-step explanation:
1 lb = 0.45359237 kg
⇒ 49 lbs = 49 x 0.45359237 = 22.22602613... kg
If the medication is administered at 5 mg/kg/day then
22.22602613... x 5 = 111.1301307 = 111 mg (to the nearest whole number)
