Answer:

Doña Juana tiene 83,782 hectáreas cultivadas en total.

Step-by-step explanation:

Dado que Doña Juana tiene cultivadas 80 hectómetros cuadrados de naranjas, 300 decámetros cuadrados de mandarinas, 700000 decímetros cuadrados de limones y 8200000 centímetros cuadrados de toronjas, para determinar cuántas hectáreas en total tiene cultivadas se deben realizar los siguientes cálculos:

1 Hm2 = 1 hectárea x 80 = 80 hectáreas

1 Dam2 = 0.01 hectárea x 300 = 3 hectáreas

1 Dm2 = 0.000001 hectárea x 700000 = 0.7 hectáreas

1 Cm2 = 0.00000001 hectárea x 8200000 = 0.082 hectáreas

80 + 3 + 0.7 + 0.082 = X

83,782 = X

Por lo tanto, Doña Juana tiene 83,782 hectáreas cultivadas en total.

Answer:

Centre = (-1, 5)

radius = 8units

Explanation

The standard form of the equation of a circle is expressed as

x^2+y^2+2gx+2fy+C = 0

Center = (-g, -f)

radius = √g²+f²-C

Given the equation of a circle is x² + y²+ 2x - 10y - 38 = 0.

On comparing

2gx = 2x

2g = 2

g = 2/2

g = 1

2fy = -10y

2f =-10

f =-5

Centre = (-1, -(-5)) = (-1, 5)

radius  = √1²+5²-(-38)

radius = √1+25+38

radius = √64

radius = 8units

Answer:

Step-by-step explanation:

x is the length of the side opposite the reference angle of 32, and 10 is the side length adjacent to the reference angle. This satisfies the tangent ratio where

[tex]tan32=\frac{x}{10}[/tex] and solving for x:

x = 10tan32

1011₂ + 10111₂

= (1000₂ + 10₂ + 1₂) + (10000₂ + 100₂ + 10₂ + 1₂)

= 10000₂ + 1000₂ + 100₂ + 2 (10₂) + 2 (1₂)

= 10000₂ + 1000₂ + 100₂ + 2 (10₂) + 10₂

= 10000₂ + 1000₂ + 100₂ + 100₂ + 10₂

= 10000₂ + 1000₂ + 2 (100₂) + 10₂

= 10000₂ + 1000₂ + 1000₂ + 10₂

= 10000₂ + 2 (1000₂) + 10₂

= 10000₂ + 10000₂ + 10₂

= 2 (10000₂) + 10₂

= 100000₂ + 10₂

= 100010₂

Answer:

[tex]-8a^{7b}[/tex]

Step-by-step explanation:

[tex](-4 a^{5b}) (2a^{2b}) = -(2^2 a^{5b}) (2a^{2b})\\[/tex]

                    [tex]= -(2 ^2 \times 2) \times a^{5b + 2b}\\\\= -(2 ^{2+1}) \times a^{7b}\\\\=-(2^{3}) \times a^{7b}\\\\= - 8 a^{7b}[/tex]

Step-by-step explanation:

Answer:

step-by-step explanation: 1cm is equal to 10mm

The volume of a cuboid is length ×breadth×height

We start by converting 60 mm into cm which will be 6cm

Solution :

462cm3=11cm×6cm

462cm3/66=66cm/66

The final answer will be 7cm

Therefore the height is 7cm

The margin of error is 0.1245 (approx) with a confidence level of 95%.

Margin of error is a statistic which is expressing the measurement of random sampling error in the results of a survey.

Margin of error = [tex]z^{*}[/tex][tex]\sqrt{\frac{p(1-p)}{n} }[/tex]

where [tex]z^{*}[/tex] is the value for confidence level or quantile,

p is the sampling mean proportion and n is the sample size.

Here, The sampling mean proportion(p)= 0.28

The sample size(n)= 50

Confidence level = 95%

Hence Value for 95% confidence level ([tex]z^{*}[/tex])= 1.96

∴ Margin of error = [tex]1.96[/tex][tex]\sqrt{\frac{0.28(1-0.28)}{50} }[/tex]

                            = [tex]1.96[/tex][tex]\sqrt{\frac{0.28*0.72}{50} }[/tex]

                            = [tex]1.96\sqrt{\frac{0.2016}{50} }[/tex]

                            = [tex]1.96\sqrt{0.004032}[/tex]

                            = [tex]1.96[/tex]×[tex]0.0635[/tex]

                            = [tex]0.1245[/tex] (approx)

So, The margin of error is 0.1245 (approx).

Answer:

18 ft

Step-by-step explanation:

Since the triangle is right angled ; we could use trigonometry ;

Using the angle , 40° ; adjacent side, = 14 feets ; hypotenus = x

Cos θ = Adjacent / hypotenus

Cos 40 = 14 / x

0.7660444 = 14 / x

0.7660444x = 14

x = 14 / 0.7660444

x = 18.27

= 18 ( nearest foot)

Answer:

Step-by-step explanation:

given :

y = 120 degree

z = 57 degree

angle x = ?

first lets find angle c in triangle BDC

angle C + 57 = 120

angle C = 120 -57

angle C = 63 degree

Now lets find angle B in triangle BDC

angle B + angle C + z = 180 degree (sum of interior angles of a triangle)

angle B + 63 + 57 = 180

angle B + 120 = 180

angle B = 180 - 120

angle B = 60 degree

now for angle x

angle B + z = angle x (sum of two interior opposite angles is equal to the exterior angle formed)

60 + 57 = x

117 = x

The answer should be A.

Answer:

2/3 ft

Step-by-step explanation:

area of triangle =base*height/2

2/5=base*6/5/2

2/5 *2 =base * 6/5

4/5 =base*6/5

4/5÷6/5=base

4/5 * 5/6=base

20/30=base

2/3=base

therefore base=2/3 ft

Answer:

210

Step-by-step explanation:

Lets use BEDMAS (Brackets, Exponents, Division, Multiplication, Addition, Subtraction)

22.5 × 8 = 180

180 - 12 = 168

As far as I can tell, all the correct examples are

1) Symmetrical

2) Have a line splitting them symmetrically and does not go above or below the shape (Does that make sense?)

The wrong examples don't have any of the characteristics told above. For example, the square would be wrong because it doesn't even have a line
