Use the area of the rectangle to find the area of the triangle. ?​

Answer:

La Comunidad A deberá aportar $60,000, la Comunidad B deberá aportar $120,000 y la Comunidad C deberá aportar $180,000. Cada Comunidad aportará $500 por persona.

Step-by-step explanation:

Dado que la obra de drenaje tiene un costo de materiales de $360,000, y que dicho costo será soportado por cada comunidad en proporción a sus habitantes, sabiendo que en la comunidad A hay 120 habitantes; en la comunidad B 240 y en la comunidad C 360, para determinar con cuánto dinero debe cooperar cada una se debe realizar el siguiente cálculo:

120 + 240 + 360 = 720

C = 1/2 x 360,000 = 180,000

B = 1/3 x 360,000 = 120,000

A = 1/6 x 360,000 = 60,000

Así, la Comunidad A deberá aportar $60,000, la Comunidad B deberá aportar $120,000 y la Comunidad C deberá aportar $180,000.

A su vez, la aportación por persona en las tres comunidades surge del siguiente cálculo:

360,000 / 720 = 500

Así, cada comunidad aportará $500 por persona.

Answer:

10080

Step-by-step explanation:

2985÷3=995×11=10080

Answer:

It can produce 32,835 in 11 days.

Step-by-step explanation:

2,985 x 3 =  8,955

2,985 x 3 = 8,955

2,985 x 3 = 8,955

If you add another three, that'll  be 12, so, we'll multiply 2,985 x 2.

2, 985 x 2 = 5,970

Now, Add all of those 4 numbers together,

8,955 + 8,955 + 8,955 + 5,970 = 32,835

Answer:

n ≈ 8.54

Step-by-step explanation:

Reference angle = 30°

Opposite side = n

Adjacent side = 14.8

Apply TOA, which is:

Tan 30 = opp/adj

Tan 30 = n/14.8

Multiply both sides by 14.8

14.8×tan 30 = n

8.54478398 = n

n ≈ 8.54 units (to 2 dp)

Answer:

1) Qualitative

2) Quantitative discrete

3) Quantitative discrete

4) Qualitative

Step-by-step explanation:

Qualitative -

It is a type of Nominal data , the values obtained from this is either Yes or No.

Quantitative discrete -

In this type , the data is finite and countable ( it only takes whole number Like 11 , 45, 60 etc.)

Quantitative continuous -

In this type of data , data values can take any value (with in a range Like 20.3 , 15.5 etc.)

1) Do you have any health problems that prevent you from doing any of the things people your age can normally do?

a) qualitative.

b) quantitative discrete.

Answer:

The equation of the circle is [tex](x + 1)^2 + y^2 = 25[/tex]

Step-by-step explanation:

Equation of a circle:

The equation of a circle of centre [tex](x_c,y_c)[/tex] has the following format:

[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]

In which r is the radius.

Center (-1,0)

This means that [tex]x_c = -1, y_c = 0[/tex]. So

[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]

[tex](x - (-1))^2 + (y - 0)^2 = r^2[/tex]

[tex](x + 1)^2 + y^2 = r^2[/tex]

Finding the radius:

Distance between the radius and the centre and a point of the circle. In this case, point (2,-4). Using the formula for the distance between two points:

[tex]r = \sqrt{(2-(-1))^2+(-4-0)^2} = \sqrt{3^2 + 4^2} = \sqrt{25} = 5[/tex]

So, the equation of the circle is:

[tex](x + 1)^2 + y^2 = 5^2[/tex]

[tex](x + 1)^2 + y^2 = 25[/tex]

thats not possible do you have options or another equation...?? because there is 2 unknown variable

Answer:

4.75 years are required to triple the population

Step-by-step explanation:

As we know

[tex]\frac{dP}{dt} = P\\[/tex]

Integrating both the side with respect to t we get

[tex]ln P = kt + c_1\\P = e^{kt + c_1}\\P = Ce^{kt}[/tex]

At t = 0, P = P0

[tex]2 P_0 = P_0 * e ^{3k}\\2 = e ^{3k}\\ln 2 = 3k\\k = 0.231\\[/tex]

substituting K value in main equation, we get -

[tex]P = P_0 * e^{0.231 * t}\\3P_0 = P_0 * e^{0.231 * t}\\3 = e^{0.231 * t}\\ln 3 = 0.231 * t\\t = 4.75[/tex]

4.75 years are required to triple the population

Step 1.

Figure out how much it costs to hire one security personal for a month

2×20×15

=600

$600 per person per month

Step 2.

Multiply that number by the no. of people needed to be hired

600×30

=18000

∴ The security labor cost for a four-week month is $18,000
