Answer:

A.) 6a=2(p+3q)

Step-by-step explanation:

Given: p=3(a-q); solve for 6a.

If we want to solve for 6a, we need to know what the value for a is. To do that, we need to isolate a on one side of the equal sign. Before we even do that, let's distribute this problem out.

p=3a-3q

Now, let's move 3a to the left side of the equation.

-3a+p=-3q

Let's move p over so we have the a on one side of the equation.

-3a=-p-3q

To solve for a, we need to take off the coefficient that is on a (-3.) To do this, divide everything by -3.

a=\frac{p}{3}+q

Now, we know what the value of a is. To find the value of 6a, multiply everything by 6.

6a=\frac{6p}{3}+6q

Simplify.

6a=2p+6q

Factor.

6a=2(p+3q)

The radius of a right circular cone is increasing at a rate of 1.6 in/s while its height is decreasing at a rate of 2.2 in/s. At
ArbitrLikvidat [17]

Answer:

Step-by-step explanation:

let radius=r

height=h

dr/dt=1.6 in/s

dh/dt=-2.2 in/s

volume v=1/3 πr²h

dv/dt=1/3 π[h*2r×dr/dt+r²×dh/dt]

when r=135 in

h=135 in

dv/dt=1/3 π[2×135×135×1.6+135²×(-2.2)]

=1/3 π[135²(3.2-2.2)]

=1/3π135²×1

=6075 π in³/s

The tanks at the Georgia Aquarium hold approximately 8.4 x 10⁶ gallons of water. The tanks at the Audubon Aquarium of the Americ
postnew [5]

The amount of water at the Georgia Aquarium is 2 * 10¹ times greater than the aquarium of the Americas hold.

<h3>How to work with scientific notation of numbers?</h3>

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

We are given that the tanks at the Georgia Aquarium hold approximately 8.4 × 10⁶ gallons of water.

Meanwhile, the tanks at the Audubon Aquarium of the Americas hold about 400,000 gallons of water.

Thus, to estimate how many times as great the amount of water is at the Georgia Aquarium, we will divide as;

(8.4 × 10⁶)/(400000)

Converting 8.4 × 10⁶ to normal number gives;

8400000

Thus;

(8.4 × 10⁶)/(400000) = 8400000/400000

= 21

Thus, writing in scientific notation gives;

2.1 * 10¹ approximately 2 * 10¹

Point A has the coordinates (3 - 7). Find the coordinates of A', the image of A after it has been translated left 4 units and do
TiliK225 [7]

Answer:  (-1,-9)

Step-by-step explanation:

If a point is translate up or down  it means your using the y coordinate an if a point is translated left or right your using the x coordinate.

So the x coordinate is  3  and is translated  to the left by 4 units so is moving back by 4 .

3-4 = -1  

The y coordinate is -7  and is also translated down by 2 units so it is also decreasing.

-7 -2 = -9  

so the image is  (-1,-9)
