uysha [10]

Answer:

Total pints of cream will they need for the pasta = 7 pints

Step-by-step explanation:

Given - Pasta Place needs to make pasta with garlic cream sauce for 80 guests at a party. One batch of pasta calls for 3 cups of cream and feeds 10 people. The restaurant already has 5 pints of cream in the fridge.

To find - How many more pints of cream will they need for the pasta?

Solution -

10 people = 3 cups of cream

⇒80 people = 8×3 = 24 cups of cream

Now,

We know that,

1 cup = 0.5 pints

⇒24 cup = 24×0.5 = 12 pints.

Now,

Given that, The restaurant already has 5 pints of cream in the fridge.

So,

Total pints more needed = 12 - 5 = 7 pints.

∴ we get

Total pints of cream will they need for the pasta = 7 pints

Find the distance between the following two points: (-4,10) and (-10, -1). Round to the nearest TENTH.
emmasim [6.3K]
Answer:

distance = 12.5

Step-by-step explanation:

Use the distance formula to find the distance between any two points

√[(x₂ - x₁)² + (y₂ - y₁)²]

Points: (-4, 10) and (-10, -1)

Step 1. Plug these points into the formula (where the first point indicates the firsts x and y coordinates and the second point indicates the seconds x and y coordinates)

√[(-10 - (-4))² + (-1 - 10)²]

Step 2. Subtract

√[6² + (-11)²]

Step 3. Simplify (exponents)

√[36 + 121]

Step 4. Add

√157

Step 5. Simplify (radical)

12.52

Step 6. Round to the nearest tenth

12.5

Why are some graphs limited to the first quadrant?
Kay [80]
Graphs limited to the first quadrant would have positive points only, for bith the x and y variables, which means there wouldnt be any points in any other quadrant.... in other words, plotted points with both variables being positive would stay within the first quadrant. hope this answers your question!!
