Answer:

5/4 times 1/3

Step-by-step explanation:

I got my answer because it said she has 1 1/4 hours to do her 3 chores and there is a mixed number in the problem so convert that mixed number to an improper and you get 5/4. Now the 3 is a whole number so we have to change that to an improper as well and that would be 3/1. Next we have to find the reciprocal of 3/1 and that would be 1/3 then you add a multiplication sign to the problem and it should look like this.

5/4 x 1/3

Write the ratio of the area of a circle with radius r to the circumference of the same circle
Goshia [24]

Answer:

\frac{r}{2\pi r} =\frac{1}{2\pi }

Step-by-step explanation:

A ratio is a comparison of two quantities and can be written in several forms including fractions. It is most commonly written in fraction form or a:b.

To write a ratio, we count the number of each quantity we are comparing or use the variable for that quantity. We write radius:circumference. Recall, the circumference of a circle can be found using \pi d or 2\pi r.

We write r: \pi d  or r:2\pi r.

We can also write in fraction form:

\frac{r}{\pi d} or \frac{r}{2\pi r} =\frac{1}{2\pi }

Given the equation -2x+3y=12, find the missing value in the ordered pair 3, <br><br> Noo linkss plz
astraxan [27]

Answer:

(3,6)

Step-by-step explanation:

-2x+3y=12

Let x = 3

-2(3) +3y = 12

-6+3y = 12

Add 6 to each side

-6+6 +3y = 12+6

3y = 18

Divide each side by 3

3y/3 = 18/3

y = 6
