Answer:
Step-by-step explanation:
x2+y2+ax+by+c=0
Step 1: Add -by to both sides.
ax+by+x2+y2+c+−by=0+−by
ax+x2+y2+c=−by
Step 2: Add -x^2 to both sides.
ax+x2+y2+c+−x2=−by+−x2
ax+y2+c=−bax+y2+c+−y2=−by−x2+−y2
ax+c=−by−x2−y2
Step 4: Add -c to both sides.
ax+c+−c=−by−x2−y2+−c
ax=−by−x2−y2−c
Step 5: Divide both sides by x.
ax
x
=
−by−x2−y2−c
x
a=
−by−x2−y2−c

Volume units quarts to gallons (fluid and dry) conversion factor is 0.25 (quart is 1/4 of an gallon). To find out how many gallons in quarts, multiply by the factor, or simply use the converter below.
1 Quart = 0.25 (1/4) Gallon [US, UK, Fluid or Dry]
Quart and gallon are imperial and US customary volume measurement units. In US customary system, both units have different volume capacity for dry and fluid measurements but in imperial (UK), the volume is the same for both fluid and dry measurement.
Answer:
$897750
Step-by-step explanation:
3990 x 225 = 897750, so the total price of the shipment is: 897750
Answer:
90 minutes
Step-by-step explanation:
Hey, there! This is a walking together question, let’s walk through it together.
Firstly, we assign a value for the volume of the swimming pool. Let’s say this is x m^3
While working together, their rate is x/30
Now, for the larger hose, it takes 45 minutes. The rate here is x/45. To find the rate at which the smaller hose takes, we simply subtract the rate of the larger hose from that of both while working together.
Mathematically this is x/30 - x/45 = 15x/1350
Now to calculate the time taken, we simply divide the volume by this rate and that is x divided by 15x/1350 or x * 1350/15x = 90 minutes
Plane A 520 feet vertical rise 40 feet/min
plane B 3800 feet vertical dip 120 feet per minute.
vertically the speeds are 40 feet / minute & 120 feet /minute.
120 + 40 = 160 feet per minute.
the distance between them = 3800 -520 =3280 feet
t= d/r
3280/160
t = 20.5 minutes. they will be at the same altitude.
