Answer:

1.3125 gallons

Step-by-step explanation:

Using the given information, we can set up a proportion;

$\frac{2.1gallons}{1.6minutes} = \frac{xgallons}{1minute}$

Now, we can cross multiply to solve for x.

2.1 = 1.6x
x = 1.3125 gallons

Answer: 1.3125 gallons

Step-by-step explanation: The machine pumps 2.1 gallons of water every 1.6 minutes. 1.6 minutes is 1.6x more than 1 minute. So, we have to divide 1.6 by 1.6. Next, we have to divide 2.1 by 1.6. We can make this a bit easier by multiplying both of them by 10 to get 21/16 which is 1.3125.

What is the general form of the equation for the given circle? A. x2 + y2 − 8x − 8y + 23 = 0 B. x2 + y2 − 8x − 8y + 32 = 0 C. x2

Answer:

The correct option is A....

Step-by-step explanation:

Look at the attached picture:

A=(4,7)

B=(7,4)

The standard form of circle equation is:

(x-h)^2 +(y-k)^2 = r^2

Here h and k is the centre which is (4,4)

radius = 7-4 = 3

Now use the formula to find the answer:

(x-h)^2 +(y-k)^2 = r^2

(x - 4)^2 + (y - 4)^2 = 3^2

If we expand the formula we get:

x^2 - 8x + 16 + y^2 - 8y + 16 = 9

x^2 - 8x + y^2 - 8y + 23 = 0

Thus the correct option is A....

Can someone please help me answer number 6!?! please!!

Hello there! Your answers would be:

a. 600 - 75x = y

b. 8 months

Need an Explanation?:

Part a:

Okay, so she has 600 dollars, and she has a monthly bill, but no income. This means she is not earning any money, only loosing some.

This equation will model your situation: 600 - 75x = y

This is because:

The 600 remains constant, you are taking away from it. The 75 x represents the amount from the total taken away after each month.
Again, she does not earn money, only spends it on her bill.
Y represents the total amount of money she has left after each month.

Part b:

This is asking us to see how many months it'll take for her to have $0. The question is telling us to have g(x) = 0. (This is just another way of saying y = 0, which translates to her having no money left)

So, plug 0 into the equation in place of y and solve for x.

600 - 75x = 0

Start by subtracting 600 from both sides to work to isolate x.

-75x = -600

Next, divide -600 by -75 to finish isolating x and get your answer.

X = 8

This means it will be 8 months before her checking account reaches 0.

So, these are your final answers. I hope this helps, and have a great day! Please don't hesitate to ask if you need more help with this specific question!
