It'll take her 15 hours.
Formula: 975= 65x
Where x represents hours
Answer:

Step-by-step explanation:
You have the following differential equation:
(1)
In order to find the solution to the equation, you can use the method of the characteristic polynomial.
The characteristic polynomial of the given differential equation is:

The solution of the differential equation is:
(2)
where m1 and m2 are the roots of the characteristic polynomial.
You replace the values obtained for m1 and m2 in the equation (2). Then, the solution to the differential equation is:

Answer:
143degrees
Step-by-step explanation:
sum of angles of a triangle =180degrees
let the third unknown angle be x
99+37+x=180
136+x=180
x=180-136
x=44
the sum of two opposite interior angles is equal to the exterior angle
44+99=<PQR
<PQR=143 degrees.
OR
the sum of angles on a straight line is 180 degrees
<PQR+37=180
<PQR=180-37
<PQR=143
Your answer is 6.643 kg
Because 1 gram is equal to 0.001 kilograms, 0.001 kg x 6,643 g = 6.643 kg
Hope this helps!
