Answer:

Step-by-step explanation:

when factoring, the two numbers that you get after you factor are also called solutions, or x intercepts. from this, we know that since the line crosses at positive 1 and positive 9, the answer must be -1 and -9 as you flip the sign after factoring to get the real answer

(ps you can also just plug in all of the answer choices to desmos and see which one matches your graph)

Students in a cooking class made 4 1/2 quarts of soup. They served 4/5 of the soup to friends. Each serving is 3/5 quart. Hector

denpristay [2]

Answer:

The correct number of servings = 6.

By saying there were $3\frac{3}{5}$ servings of soup, Hector must have intended to say that there were $3\frac{3}{5}$ quarts of soup for serving.

Step-by-step explanation:

Given:

Total quarts of soup made by students = $4\frac{1}{2}$

Fraction of the soup served to friends = $\frac{4}{5}$

Each serving = $\frac{3}{5}$ quarts

Hector incorrectly says that that there were $3\frac{3}{5}$ servings of soup.

To find the correct number of servings and to identify Hector's mistake.

Solution:

Total quarts of soup made = $4\frac{1}{2}=\frac{9}{2}$

Fraction of total quarts served = $\frac{4}{5}$

Thus, total quarts of soup served = $\frac{9}{2}\times \frac{4}{5}$

⇒ $\frac{18}{5}=3\frac{3}{5}$

Thus, total quarts of soup for serving = $\frac{18}{5}$ or $3\frac{3}{5}$

Each serving = $\frac{3}{5}$ quarts

Total number of servings can be given as:

⇒ $\frac{Total\ quarts\ of\ serving}{Size\ of\ each\ serving}$

⇒ $\dfrac{\frac{18}{5}}{\frac{3}{5}}$

To divide fractions, we take reciprocal of the divisor and replace divsion with multiplication.

⇒ $\frac{18}{5}\times \frac{5}{3}$

⇒ $\frac{18}{3}$

⇒ 6 servings

Thus, the correct number of servings = 6.

By saying there were $3\frac{3}{5}$ servings of soup, Hector must have intended to say that there were $3\frac{3}{5}$ quarts of soup for serving.

On a coordinate plane, what is the distance between the point at (1, 9) and the point at (4, 9)? (Hint: Look at the x-coordinate

TiliK225 [7]

Answer:

The answer is 3 units apart.

Step-by-step explanation:

The points are (1,9) and (4,9). The y-coordinates are the same. The x-coordinates are different. To find the difference between them, you must subtract them. 4-1=3, so the points are 3 units apart!

A book sold 34,600 copies in its first month of release. Suppose this represents 8.6% of the number of copies sold to date. How

NemiM [27]

Answer:402325.6

Step-by-step explanation:

let a be the total sales till date

8.6% of a=34600

8.6/100 x a=34600

0.086 x a=34600

divide both sides by 0.086

(0.086 x a)/0.086=34600/0.086

a=402325.6
