How many gallons of water are in the tank when the pumps were turned on

1 answer:

7 0

If the question is asking how much water was in the tank the instant that the water was turned on, that means that it is asking how much water was in the tank when t=0
To solve this we simply plug in t=0 into out equation
V(0)=65(0)+280=280 gallons of water.

HELPP 35 POINTS!!!!! Point Q is the center of Circle Q in the diagram below. The measure of angle XAY is 72° (m∠XAY = 72°). Sinc

Answer:

Se explanation

Step-by-step explanation:

The diagram shows the circle with center Q. In this circle, angle XAY is inscribed angle subtended on the arc XY. Angle XQY is the central angle subtended on the same arc XY.

The inscribed angle theorem states that an angle inscribed in a circle is half of the central angle that subtends the same arc on the circle. Therefore,

$m\angle XBY=2m\angle XAY=2\cdot 72^{\circ}=144^{\circ}$

The measure of the intercepted arc XY is the measure of the central angle XQY and is equal to 144°.

All angles that have the same endpoints X and Y and vertex lying in the middle of the quadrilateral XAYQ have measures satisfying the condition

$72^{\circ}$

because angle XAY is the smallest possible angle subtended on the arc XY in the circle and angle XQY is the largest possible angle in the circle subtended on the arc XY.

Jill estimated she would spend $50.00 a month on clothing. However, at the end of the year she discovered she actually spent $71

50$ per month for 12 years would mean she spent only (50 x 12) 600$ per year.

She actually spent $711, her forecast was off target by (600-7111) $111.

She exceeded her budget by $111
