Answer:

perimetro = \dfrac{(3 + \sqrt{3})m}{2}

Step-by-step explanation:

triángulo 30°-60°-90°

1~:~\sqrt{3}~:~2

1m~:~m\sqrt{3}~:~2m

\dfrac{m}{2}~:~\dfrac{m\sqrt{3}}{2}~:~m

perimetro = \dfrac{m}{2} + \dfrac{m\sqrt{3}}{2} + m

perimetro = \dfrac{m}{2} + \dfrac{m\sqrt{3}}{2} + \dfrac{2m}{2}

perimetro = \dfrac{m + m\sqrt{3} + 2m}{2}

perimetro = \dfrac{3m + m\sqrt{3}}{2}

perimetro = \dfrac{(3 + \sqrt{3})m}{2}

postnew [5]

Answer: She will give 8 square meter area to school snap pea plant.

Step-by-step explanation:

Given: Area required by each planter box = \dfrac45 square meter

Total number of snap pea seeds  = 10

The total area required =  (Area required by each planter box ) x (number of snap pea seeds)

=\dfrac45\times10\\\\=4\times2=8

Hence, she will give 8 square meter area to school snap pea plant.

What is the concentration after 11 minutes? Ground to 3 decimal places.
sergiy2304 [10]

In order to find the concentration after 11 minutes, let's use the value of t = 11 in the function C(t) and then calculate its value:

\begin{gathered} C(t)=0.04(1-e^{-0.2t}) \\ C(11)=0.04(1-e^{-2.2}_{}) \\ C(11)=0.04(1-0.1108) \\ C(11)=0.04\cdot0.8892 \\ C(11)=0.035568 \end{gathered}

Rounding to three decimal places, we have a concentration of 0.036.

What is the solution to this set of equations?
Vesnalui [34]

Answer:

(3,0)

Step-by-step explanation:

2x + 2y = 6  divide thru by 2 and you get  x + y = 3  

Name   x + y = 3  equation (1) and  x - y = 3 equation (2)

Add equations (1) and (2)  

 (1)   x+ y = 3

 (2) <u> x - y = 3   </u>  

        2x = 6

          x = 3  

Substitute x = 3 into equation (1).  So, 3 + y = 3

                                                                    y = 0

Greeley [361]

Answer:

An experimental study

Step-by-step explanation:

An experiment deliberately imposes some treatment on individuals in order to observe their responses.

An experimental studies formulates some conditions in order to make an inference. An observational study tries to gather information without disturbing the scene they are observing.

This is then an experiment because people are deliberately asked to taste two muffins and asked for their response.

celeste wants to have her hair cut and permed and also go to lunch. she knows she will need 59$. the perm cost twice as much as
miv72 [106K]
Let's first start off with an equation to represent Celeste's budget:
h + p + l = 59
Where:
'h' is the money in dollars that she needs to get her hair cut
'p' is the money in dollars that she needs to get her hair permed
'l' is the money in dollars that she needs for lunch

Now let's simplify this equation using the information that was given:
l = 5 *This must be true since it is told that she needs $5 for lunch
0.5p = h *This is because the perm costs twice as much as the hair cut

Our new/updated equation is:
0.5p + p + 5 = 59

This is much easier to solve, let's rearrange and solve for 'p':
0.5p + p = 59 - 5
1.5p = 54
p = 36

Therefore the perm costs $36

I hope this helps! Let me know if you have any further questions.
