Answer:

area of the regular hexagon to the nearest hundredths is, 374.12 cm²

Step-by-step explanation:

Area of a regular hexagon(A) is given by:

A = \frac{3\sqrt{3} }{2}a^2        ....[1]

where,

a  is the side length of the hexagon.

As per the statement:

a side length of regular hexagon 12 cm

⇒ a = 12 cm

Substiute in [1] we have;

A = \frac{3\sqrt{3} }{2}(12)^2

⇒A = \frac{3\sqrt{3} }{2} \cdot 144

⇒A = 3\sqrt{3 } \cdot 72 = 216\sqrt{3} = 374.112 square cm.

Therefore, the area of the regular hexagon to the nearest hundredths is,  374.12 square cm

Emily's vacuum cleaner has a power rating of 200 watts. If the vacuum cleaner does 360000 joules of work, how long did Emily spe
MakcuM [25]
To answer this, we need to know the formula of the relationship between the work and the power rating and time.

The formula is:
E(J)<span> = </span>P(W) ×<span> t</span><span>(s)
</span>360000 = 200 * t
t = 360000 / 200
t = 1800 s

So, Emily will spend 1800 seconds in vacuuming. It is also equivalent to 30 minutes.

How do u find slope on the graph
Shkiper50 [21]

Answer:

you get 2 coordinates x one, y one, x two, and y two and then do rise over run which is y two - y one over x two - x one say x one is 4 and y one is 7 and x two is 8 and y two is 13 you say 13-7=6 and 8-4=4 so it is 6/4 hope that makes sense

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.
