The nth figure requires 23 matchsticks to build, because with each successive figure you're adding 6 more matchsticks: (5+6=11) (11+6=17) (17+6=23)

What are the coordinates of the centroid of a triangle with vertices J(−4, 2) , K(2, 4) , and L(0, −2) ?

Kryger [21]

Given the coordinates of the three vertices of a triangle ABC,
the centroid coordinates are (x1+x2+x3)/3, (y1+y2+y3)/3
<span>so (-4+2+0)/3=-2/3, ]2+4+(-2)]/3=4/3
so the coordinates are (-2/3, 4/3)</span>

X = 0.19

Luda [366]

Step-by-step explanation:

.19 = 19/100

.864 = 86.4/100

.5348 = 53.48 /100

I multiplied the decimal by 100 to get what it was before which is the same as moving two decimal places to the right and divided by 100

if any confusion ask

How many units of a 10% solution are needed to prepare 500 units of a 2% solution?

Akimi4 [234]

First find how many units of solution there is:

500* 2% = 500(.02) = 10 units

You need 10 units of solution in 'x' units of a 10% solution.

x*10% = 0.1x = 10 units -----> x = 10/0.1 = 100

100 units are needed

Total number of cubic inches of cheese sauce in container = Volume of cylinder = $\pi .8^2.7$

Option A is correct.

Step-by-step explanation:

The diameter of cylinder = 16 inches

The height of cylinder = 7 inches

Total number of cubic inches of cheese sauce in container = Volume of cylinder = ?

The formula used to find Volume of cylinder is:

$Volume=\pi r^2h$

We are given diameter of cylinder while we need radius according to formula.

So, radius = diameter/2

radius = 16/2

radius = 8

Putting values and finding volume:

$Volume=\pi .8^2.7$

So, Total number of cubic inches of cheese sauce in container = Volume of cylinder = $\pi .8^2.7$

Option A is correct.
