A vine called the mile a-minute weed is known for growing at a very fast rate. It can grow up to 0.25 inches
jek_recluse [69]

Answer:

\displaystyle =\frac{0.5\text{ ft}}{\text{day}}

The weed grows at a rate of 0.5 feet per day.

Step-by-step explanation:

The weed grows at a rate of 0.25 inches per hour.

And we want to convert this rate into feet per day.

We have that:

\displaystyle \frac{0.25\text{ in}}{\text{hr}}

We knowt that there are 12 inches in one foot.

And since we want to cancel the inches, we can write our conversion factor as ft / 12 in.

We also know that there are 24 hours in one day.

And since we want to cancel the hours, we can write our conversion factor as 24 hr / day.

Hence:

\displaystyle \frac{0.25\text{ in}}{\text{hr}}\cdot\frac{\text{ft}}{12\text{ in}}\cdot \frac{24\text{ hr}}{\text{day}}

Multiply and cancel common terms. So:

\displaystyle =\frac{0.5\text{ ft}}{\text{day}}

The weed grows at a rate of 0.5 feet per day.

An amount of money 960gh was contributed by 80 students. If 714gh was contributed equally by 68 girls and the remaining amount w
VLD [36.1K]

Each girl contributed 10.50gh

Each boy contributed 20.50gh

These are further explained and computed below:

The measure of central tendency being tested here is the mean, in other words, the resulting average when the total amount contributed by girls or boys is divided by the number of girls or boys.

The fact that 68 of the 80 students are girls means that the remaining 12 students are boys because 80 minus 68 gives 12.

each girl's contribution=total girls' contribution/number of girls

each girl's contribution=714/68

each girl's contribution=10.50gh

Total boys' contribution=total contribution-total girls' contribution

Total boys' contribution=960-714

Total boys' contribution=246

each boy's contribution=Total boys' contribution/number of boys

each boy's contribution=246/12

each boy's contribution=20.50gh

Similarly, details on computing the contribution of each sex can be found in the link
