iVinArrow [24]

$\huge\mathrm{ \it{Answer࿐}}$

Increase = 20 - 15 = 5 points

$\boxed{ \% \: increase \: = \frac{5}{15} \times 100 }$

$\% \: \:increase = \frac{100}{3}$

$\% \: \:increase = 33.33$

Answer: $tan(V)=2.92$

Step-by-step explanation:

For this exercise you need to remember the following Trigonometric Identity:

$tan\alpha =\frac{opposite}{adjacent}$

You must observe the figure given in the exercise.

You can notice that the given triangle UVW is a Right triangle (because it has an angle that measures 90 degrees).

So, you can identify in the figure that:

$\alpha =V\\\\opposite=UW=35\\\\adjacent=VW=12$

Knowing these values, you can substitute them into $tan\alpha =\frac{opposite}{adjacent}$ :

$tan(V)=\frac{35}{12}$

Now you must evaluate:

$tan(V)=2.916$

Finally, rounding to the nearest hundreth, you get:

$tan(V)=2.92$

The diagram shows the ratio of trees Maeve plants to the trees she harvests.

AnnZ [28]

Answer:

WEDNESDAY: 45 planted.

THURSDAY: 22 Harvested.

Step-by-step explanation:

Based on the information given in the problem, Maeve plants 5 trees for every 2 tree she harvests. Then the ratio can be expressed as following:

$5:2$ or $\frac{5}{2}$

Then, you can complete the values in the table as you can see below:

<u>WEDNESDAY</u>

$\frac{5}{2}=\frac{planted}{18}\\\\planted=\frac{18*5}{2}\\\\planted=45$

<u>THURDAY</u>

$\frac{5}{2}=\frac{55}{harvested}\\\\(harvested)(\frac{5}{2})=55\\\\harvested=\frac{55*2}{5}\\\\harvested=22$
