HELP URGENT I WILL GIVE 20 POINTS

Mathematics

Lunna [17]4 years ago

h = 9.2 cm

Solution:

Base of smaller triangle = 5 cm

Height of smaller triangle = 2.3 cm

Base of larger triangle = 15 cm + 5 cm = 20 cm

Height of larger triangle = h

$\frac{2.3}{5}=\frac{h}{15+5}

$\frac{2.3}{5}=\frac{h}{20}

Multiply by 20 on both sides.

$20 \times \frac{2.3}{5}=\frac{h}{20} \times 20

$\frac{46}{5}=h

9.2 = h

So that Ryan should have add 15 and 5 to get a denominator of 20 on the right sides of the first line. Doing so gives the correct value, h = 9.2 cm.

The data from 200 endothermic reactions involving sodium bicarbonate are summarized as follows: calculate the probability mass f
In-s [12.5K]
Given the table below which contains data from 200 endothemic reactions involving <span>sodium bicarbonate:

\begin{tabular}&#10;{|c|c|}&#10;Final Temperature Conditions&Number of Reactions\\[1ex]&#10;266 K&48\\&#10;271 K&60\\&#10;274 K&92&#10;\end{tabular}

We find the probability distribution function as follows:

Let X denote the final temperature, then
</span>
<span>P(X = 266) =  \frac{48}{200} =0.24\\ \\ P(X = 271) =  \frac{60}{200} =0.3\\ \\ P(X = 274) =  \frac{92}{200} =0.46</span>

I'm making a table.
viva [34]
I hope this picture helps, but next time try to chose a number to cancel out the fraction. Example, y=1/3x+4 chose 3,6,9 and other multiples of 3.

How do I construct bisectors, angles, &amp; segments?
Doss [256]

Answer:

Step-by-step explanation:

These come directly from my textbook, so I'm not sure if your teacher will accept this kind of work.

1. Angle construction:

Given an angle. construct an angle congruent to the given angle.

Given: Angle ABC

Construct: An angle congruent to angle ABC

Procedure:

1. Draw a ray. Label it ray RY.

2. Using B as center and any radius, draw an arc that intersects ray BA and ray BC. Label the points of intersection D and E, respectively.

3. Using R as center and the same radius as in Step 2, draw an arc intersecting ray RY. Label the arc XS, with S being the point where the arc intersects ray RY.

4. Using S as center and a radius equal to DE, draw an arc that intersects arc XS at a point Q.

5. Draw ray RQ.

Justification (for congruence): If you draw line segment DE and line segment QS, triangle DBE is congruent to triangle QRS (SSS postulate) Then angle QRS is congruent to angle ABC.

You can probably also Google videos if it's hard to imagine this. Sorry, construction is super hard to describe.
