Question 9 of 26

Arturiano [62]

Answer: f(x) = 1.2(x/2) if 120 ≤ x ≤ 240

Step-by-step explanation:

Let, she made f(x) sundaes in x minutes.

Then according to the question,

She just makes sundaes for a single shift of at most 4 hours and at least 2 hours,

⇒ She can make sundaes for a single shift of at most 240 minutes and at least 120 minutes,

That is, 120 ≤ x ≤ 240

Now, She can prepare 1 sundae every 2 minutes,

⇒ She can prepare 1/2 sundae every 1 minutes,

⇒ She can prepare x/2 sundae every x minutes,

Also, she earns $1.20 for each sundae she makes.

Thus, her total earning in x minutes,

$f(x)= 1.2\times \frac{x}{2}$

⇒ $f(x)= 1.2(\frac{x}{2})$

Where, 120 ≤ x ≤ 240

Which is the required function related her earnings to the number of minutes she works.

A canoe requires 8 hours of fabrication and a rowboat 5 hours. The fabrication departments has at most 107 hours of labor availa

Elina [12.6K]

Answer: A

Step-by-step explanation: Canoe → 8h →X

Rowboat → 5h → Y

Fabrication department has at most 107, which means it need to be less than 107 hours.

This way, the amount of time to fabricate X canoes = 8X plus the amount of time to fabricate Y Rowboat = 5Y must be less than 107.

8X + 5Y < 107

Jarred sells DVDs. His inventory shows that he has a total of 3,500 DVDs. He has 2,342 more contemporary titles than classic tit

cestrela7 [59]

X + y = 3,500 . . . (1)
x – y = 2,342 . . . (2)
(1) - (2) => 2y = 1158
y = 1158/2 = 579
x = 3500 - 579 = 2921

Therefore, he had 2,921 contempolary titles and 579 classic titles.

2^-3 x 3^-2 2 to the power of negative 3 times by 3 to the power of negative 2

Ivan

<h3>The value of 2 to the power of negative 3 times by 3 to the power of negative 2 is 0.013889</h3>

Solution:

Given that:

$2^{-3} \times 3^{-2}$

We have to find the value of expression

We know that,

$a^{-n} = \frac{1}{a^n}$

Therefore,

$2^{-3} \times 3^{-2} = \frac{1}{2^3} \times \frac{1}{3^2}$

We know that,

$a^2 = a \times a$

Similarly,

$2^{-3} \times 3^{-2} = \frac{1}{2 \times 2 \times 2} \times \frac{1}{3 \times 3}\\\\Simplify\\\\2^{-3} \times 3^{-2} = \frac{1}{8} \times \frac{1}{9}\\\\2^{-3} \times 3^{-2} = \frac{1}{72}\\\\Simplify\\\\2^{-3} \times 3^{-2} = 0.013889$

Thus value of 2 to the power of negative 3 times by 3 to the power of negative 2 is 0.013889
