Answer: 200 square units

Step-by-step explanation:

first you think what 60/3 is and you get 20

then you multiply 20x20 and get 400

then you divide by 2 because to find the area of a triangle you use the formula (lxh)/2

Answer:

The slope is $0.35/min and it gives the cost per minute of the phone used.

Step-by-step explanation:

We can model this situation with a linear equation of the form

$y =mx+b$

where $y$ is monthly cost, $x$ is the number of minutes, $b$ is the flat monthly fee, and $m$ is the slope of the equation, or in our case, the amount of money charged per minute.

The slope $m$ is

$m= \dfrac{\$372.5-\$131}{990min-300min}$

$m = \$0.35/min$ ,

in other words, the phone company charges $0.5 per minute.

With the slope in hand, the linear equation becomes

$y =0.35x+b$ ,

and we can find the monthly fee $b$ from that fact that for 300 minutes the cost is $131:

$\$131 = 0.35(300min) +b$

$b = \%26$ .

Therefore,

$y = 0.35x+26$

where the slope if the equation give the cost per minute of the phone used.

The cylindrical container is four-fifths full of powder. Round to the nearest tenth if necessary. a. The total capacity of the c

mezya [45]

Answer:

a. $\pi r^2h$

b. $\frac{4\pi r^2h}{5}$

Step-by-step explanation:

Volume of the container denotes its quantity. It is a three-dimensional space.

Let V denotes the volume of the container, h denotes the height of the container and r denotes the radius of the container.

The total capacity of the container in terms of π is $\pi r^2h$ <u />

As the cylindrical container is four-fifths full of powder, so the volume of the powder in terms of π is $\frac{4}{5}\times$ volume of the container i.e., $\frac{4\pi r^2h}{5}$
