9514 1404 393

Answer:

  2)  3 pages per hour

  3)  4/29 km per minute

Step-by-step explanation:

Division by a fraction is the same as multiplication by the inverse of that fraction.

<h3>2) </h3>

  \dfrac{\ \dfrac{9}{4}\ }{\dfrac{3}{4}}=\dfrac{9}{4}\times\dfrac{4}{3}=\dfrac{36}{12}=\boxed{3\text{ pages per hour}}

__

<h3>3) </h3>

  \dfrac{2\text{ km}}{\dfrac{29}{2}\text{ min}}=2\times\dfrac{2}{29}\text{ km/min}=\boxed{\dfrac{4}{29}\text{ km/min}}

What is the angle of rotation counterclockwise about the spinner’s center that maps label j to label A?
AysviL [449]

Answer:

C. 324°

Step-by-step explanation:

We are given that,

The spinner is rotated 180° counter-clockwise about the center and maps J to A.

Since there are 10 sections of the spinner.

So, the angle by each section = \frac{360}{10} = 36°

That is, the angle which maps J to A clockwise is 36°

<h3>Then, the angle which maps J to A counter-clockwise = 360° - 36° = 324°</h3>

Thus, option C is correct.

What is 9lbs 6 oz converted to ounces
Tju [1.3M]

Hey there~☺

Answer:\boxed{150\text{ ounces}}

Explanation:

9 Ibs(pounds) + 6 oz(ounces) ⇒ ounces

First, let's find out how many 1 pound is equal to in ounces.

1\text{ pound}\rightarrow16\text{ ounces}

Since 1 pound is equal to 16 ounces, multiply the 9 pounds by 16.

9*16=144

Now, add the remaining 6 ounces to 144 ounces, which is also 9 pounds.

144+6=150

The answer is 150 ounces.

Hope this helps!☺
