It’s quite easy here.

A sum means addition.
The term “of a number” means youre dealing with a variable.

10 is an Interger. Put those two together and you end up with:

A ceramist uses (v²+ v) pints of glaze for v porcelain vases. What is the maximum number of vases

zmey [24]

By factoring the quadratic equation, 4 porcelain vases can be glazed with 20 pints of glaze. (Correct choice: B)

<h3>How much vases can be glazed with a certain amount of pints of glass?</h3>

Herein we have a quadratic equation that models the quantity of pints as a function of the number of vases, we need to solve the quadratic equation for v to find the required quantity. The complete procedure is shown below:

v² + v = 20 Given

v² + v - 20 = 0 Compatibility with addition / Existence of the additive inverse / Modulative property

(v + 5) · (v - 4) = 0 x² - (r₁ + r₂) · x + r₁ · r₂ = (x - r₁) · (x - r₂)

The result must be a positive number and, thus, the maximum number of vases must be equal to 4. By factoring the quadratic equation, 4 porcelain vases can be glazed with 20 pints of glaze. (Correct choice: B)

a train is traveling from New Orleans to Memphis at a constant speed of 79 miles per hour.New Orleans and Memphis are 395.1 mile

alexdok [17]

Just use the formula time = distance / speed

395.1/79= 5.001

It will take the train approximately five hours to reach Memphis

11. Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule.

azamat

Answer:

Step-by-step explanation:

The first term is simply a(1), and is 5.

The fourth term is a(4), and is 5 + (1/6)(4-1), or 5 3/6 or 5 1/2.

The tenth term is a(10), and is 5 + (1/6)(10 - 1), or 5 + 3/2, or 6 1/2.

-7 2/3 + (-5 1/2) +8 3/4

Vika [28.1K]

Answer:

$-4\frac{5}{12}$

Step-by-step explanation:

Here we have three terms, none with matching denominators.

Now we have to find the least common multiple of 3, 2, and 4. We can ignore the 2 here because the 4 takes care of that. The least common multiple of 3 and 4 is 12. 12 is also divisible by 2, so we've fulfilled those terms.

Now, let's get to work. We have to convert all of those mixed numbers into fractions with a denominator of 12. I'll skip the explanation and just do the work step by step. Ask questions if you are unsure of something.

First, we'll just put them all in a row.

$-7\frac{2}{3} -5\frac{1}{2} +8\frac{3}{4}$

Next, I'm going to put them in the forms of improper fractions, just to make this a bit less cluttered.

$-\frac{23}{3} -\frac{11}{2} +\frac{35}{4}$

Then, I'll adjust the denominators of the fractions by multiplying the whole fraction by whatever it takes to make that denominator 12. Remember, multiply the numerator and the denominator by the same number.

$-\frac{23}{3}(\frac{4}{4})-\frac{11}{2}(\frac{6}{6})+\frac{35}{4}(\frac{3}{3})$

$-\frac{92}{12} -\frac{66}{12} +\frac{105}{12}$

Now, let's add them together.

$-\frac{53}{12}$

You can leave this as an improper fraction, but I'm going to put this into mixed number form for you.

$-4\frac{5}{12}$
