What is 287.9412 rounded to the nearest tenth?

Westkost [7]

Hello!

If we want to round 287.9412 to the nearest tenth, the answer would be 287.9

Since rounding to the nearest tenth would mean rounding the first decimal, that's why it gives us that answer.

Also:

287.9412

2 = hundreds

8 = tens

7 = ones

. = decimal

9 = tenths

4 = hundredths

1 = thousandths

2 = millionths

Hope this helped! c:

Determine the measure of an interior angle of the named regular polygon. If a side of the polygon is extended, determine the sup

ladessa [460]

Answer:

A) Each interior angle of the Regular Hexagon = 120°

B)The measure of the supplementary angle of an interior angle is 60°

Step-by-step explanation:

Regular Hexagon : A 6 sided polygon which has all 6 interior angles as EQUAL is called a regular hexagon.

So, here are 6 interior angles of the hexagon are equal.

Also, Sum of all interior angles of an hexagon = 720°

Let us assume the each angle of the hexagon = m

⇒ m + m + m + m + m + m = 720°

or, 6 m = 720°

or, m = 720° / 6 = 120°

⇒ Each interior angle of the Regular Hexagon = 120°

Now, a side is extended to form an exterior angle.

Let us assume the measure of that exterior angle = k

⇒ k + m = 180 ° ( as k and m are SUPPLEMENTARY ANGLES)

or, k = 180 - 120 = 60 °

or, k = 60 °

Hence, the measure of the supplementary angle of an interior angle is 60°

P(-2, -1) start at 0. Go to the left two squares, then go down 1 square. mark a point there
Q(2, 4) start at 0. Go to the right two squares, go up 4 squares. mark a point there.
connect two points
make a right triangle
Then use the pythereom

When purchased, the height of a Japanese maple sapling is 14 inches. The tree is expected to grow 2.5 inches each month. Which f

victus00 [196]

Answer:

Step-by-step explanation:

The initial height of a Japanese maple sapling is 14 inches.

The tree is expected to grow 2.5 inches each month. This increase in height is linear, thus it is in arithmetic progression.

The expression for arithmetic progression is

Tn = a + (n-1)d

Where a = the first term of the series

d = common difference

Tn is the nth term of the series

n = the number of terms.

From the information given

a = 14 inches because it is the initial height of the tree

d = 2.5 because it is the difference in height between 2 consecutive months

n = m( number of months)

Tn = f(m)

function models the relationship between the height of the tree f(m) and the number of m months of growth will be

f(m) = 14 + 2.5(m-1)
