What's the slope intercept for of (4,3) and (4,-4

1 answer:

4 0

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{-4 - 3}{4 - 4} = \frac{-7}{0}$
y - y₁ = m(x - x₁)
y - 3 = ⁻⁷/₀(x - 4)
y - 3 = ⁻⁷/₀(x) + ⁷/₀(4)
y - 3 = ⁻⁷/₀x + ²⁸/₀
+ 3 + 3
y =⁻⁷/₀x + 3 + ²⁸/₀

At a museum cafe you can get a pre-made boxed lunch with a sandwich, fruit, and drink for only . The sandwiches are made with ei

slamgirl [31]

Answer:

1/8 or 0.125

Step-by-step explanation:

So, I started solving this problem by writing all the possible options, then pairing them each up with a fruit and drink..

...But when I read the question again, I noticed I forgot to leave out the fruit, as this question states that you're trying to retrieve "a turkey sandwich and a bottle of water.."

Well, oof.

Despite that, I'm still giving this answer as if it never left out the fruit. So, let's see what we need to do.

To find all the possible lunch options, I started out by writing down one of our meats, Turkey. As per requested, I made every possible turkey combination that included a fruit and drink, which gave me this:

Turkey, apple and water
Turkey, orange and water
Turkey, orange and juice
Turkey, apple and juice

Same for the ham:

Ham, apple and water
Ham, apple and juice
Ham, orange and juice
Ham, orange and water

Putting these together, this gives up 8 different lunchbox combinations. If we're trying to get one and we randomly select it, then we have a 1/8 chance of grabbing the turkey sandwich and a bottle of water....

..and a fruit.

Hope this helped!

If you need me to show my work, just comment me and I will attach a screenshot!

Suppose that a large mixing tank initially holds 400 gallons of water in which 70 pounds of salt have been dissolved. Pure water

Setler79 [48]

Answer:

Step-by-step explanation:

Given that a large mixing tank initially holds 400 gallons of water in which 70 pounds of salt have been dissolved. Pure water is pumped into the tank at a rate of 4 gal/min, and when the solution is well stirred, it is then pumped out at the same rate.

Let Q(t) be the quantity of salt at time t.

Q(0) = 70 pounds

Inflow of water = outflow = 4 gal/min

So resulting volume of tank at time t = 400 gallons

Rate of change of salt = inflow - outflow

= 0 - $\frac{Q(t)}{400}$
