To solve, you need to carry the decimal two spaces to the right because there are two zero in 100 so 0.17 times 100 is 17.  The height of the tree after ten years was 17 meters tall in height.

Answer:

17 meters

Step-by-step explanation:

Given: Jennifer planted a tree that was 0.17 of a meter tall. After 10 years, the tree was 100 times as tall as when she planted it.

To find: Height of the tree after 10 years.

Solution:

When the tree is planted, the height of the tree is 0.17 meter.

It is given that after 10 years the tree was 100 times as tall as when it is planted.

So, to find the height of the tree after 10 years we need to multiply 100 and 0.17

Now, 100\times0.17=100\times\frac{17}{100}=17

Hence, the height of the tree after 10 years is 17 meters.

Which equations are equivalent to Y=2/3X-4 when written in slope-intercept form? Check all that apply. A =3X-2Y=4. B=2X-3Y=12. C
klemol [59]

Answer:

B and C

Step-by-step explanation:

Rearrange each equation into slope- intercept form

A

3x - 2y = 4 ( subtract 3x from both sides )

- 2y = - 3x + 4 ( divide all terms by - 2 )

y = \frac{3}{2} x - 2 ← not equivalent

B

2x - 3y = 12 ( subtract 2x from both sides )

- 3y = - 2x + 12 ( divide all terms by - 2 )

y = \frac{2}{3} x - 4 ← equivalent

C

- 4(2x - 3y ) = - 48 ( divide both sides by - 4 )

2x - 3y = 12 ← same as B ⇒ equivalent

D

2(x + 6) = 3y

3y = 2x + 12 ( divide all terms by 3 )

y = \frac{2}{3} x + 4 ← not equivalent

E

2x - 3y = 4 ( subtract 2x from both sides )

- 3y = - 2x + 4 ( divide all terms by - 3 )

y = \frac{2}{3} x - \frac{4}{3} ← not equivalent

M is the incenter of triangle ABC. Find the lengths of MD and DC. (Look at pic)
Deffense [45]

Answer:

Part 1) MD=9\ units

Part 2) DC=12\ units

Step-by-step explanation:

Step 1

Find the length of MD

we know that

The incenter is the intersection of the angle bisectors of the three vertices of the triangle. Is the point forming the origin of a circle inscribed inside the triangle

so

In this problem

MD=ME=MF ------> is the radius of a circle inscribed inside the triangle

we have that

MF=9\ units

therefore

ME=9\ units

MD=9\ units

Step 2

Find the length of DC

we know that

In the right triangle MDC

Applying the Pythagoras theorem

MC^{2} =MD^{2}+DC^{2}

we have

MD=9\ units

MC=15\ units

substitute

15^{2} =9^{2}+DC^{2}

DC^{2}=225-81

DC=\sqrt{144}\ units

DC=12\ units

Distribute the 2 first.

f(n) = 2n - 2 + 3n

Combine like terms.

f(n) = 5n - 2
