The scale drawing of a field in the shape of a triangle is shown below. What is the actual area, in square meters, of this feild?

Answers

Answer:

The area of the field is 70 square meters

Step-by-step explanation:

Given

See attachment for scale drawing

Required

The actual area

From the scale drawing, we have;

[tex]Base = 7[/tex]

[tex]Height = 5[/tex]

So, the area of the scale is:

[tex]Area = 0.5 * Base * Height[/tex]

[tex]Area = 0.5 * 7 * 5[/tex]

[tex]Area = 17.5[/tex] square units

Also from the attached scale,

[tex]1\ unit = 2m[/tex]

So, we have:

[tex]Area = 17.5 * (2m)^2[/tex]

[tex]Area = 17.5 * 4m^2[/tex]

[tex]Area = 70m^2[/tex]

The area of the field is 70 square meters

Answer:

m= 188 and Angle 3 = 90-47 = 43

Step-by-step explanation:

Answer:

[see below]

Step-by-step explanation:

From the question given, angle 3 is a complement of angle 4, and angle 4 is 47 degrees.

Complementary angles add up to 90 degrees.

[tex]90 - 47 = 43[/tex]

Angle three should measure 43 degrees.

3. If x and y vary directly, and x = 60 when y = 5, what is the value of у when x = 36 ?

Answers

Answer:

y = 3

Step-by-step explanation:

Use the direct variation equation, y = kx

Plug in 60 as x and 5 as y, and solve for k

y = kx

5 = k(60)

1/12 = k

So, the equation is y = 1/12x

Plug in 36 as x and solve for y

y = 1/12x

y = 1/12(36)

y = 3

So, when x = 36, y = 3

A rectangular plot of land has an area of 8/3 square miles and a length of 3/5 mile. What is the width of the plot of land? F.9/40 mi G.5/8 mi H.1 3/5 J.4 4/9

Answers

Answer:

Width = x mile = 4 4/9 mile

J.4 4/9

Step-by-step explanation:

Area of a rectangle = length × width

Area of the rectangular plot = 8/3 square miles

Length = 3/5 mile

Width = x mile

Area of a rectangle = length × width

8/3 = 3/5 * x

8/3 = 3/5x

x = 8/3 ÷ 3/5

Multiply 8/3 by the reciprocal of 3/5

x = 8/3 × 5/3

= (8*5) / (3*3)

x = 40/9

x = 4 4/9 mile

Width = x mile = 4 4/9 mile

Find the value of x.

A garage door code has 5 digits. If no digit is repeated, how many codes are possible?

Hint: the possible digits are 0-9

Answers

Answer:

There are 30240 possible codes.

Step-by-step explanation:

For the first digit, there are 10 number choices possible:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

For the second digit, 9 number choices, because one of the digits cannot be repeated.

For the third, 8 number choices, because two of the digits cannot be repeated.

For the fourth, 7 number choices, because three of the digits cannot be repeated.

For the fifth, 6 number choices because four of the digits cannot be repeated.

Now multiply all the numbers, and you can see that there are 10*9*8*7*6, or 30240 codes possible.

En 3 paquetes iguales hay 24 velitas en total. A) ¿Cuántas habrá en 19 paquetes iguales? B) ¿Cuántos paquetes iguales a estos se podrían armar con 320 velitas?

Answers

Answer:

A) En 19 paquetes habrá 152 velitas.

B) Se podrían armar 40 paquetes iguales con 320 velitas.

Step-by-step explanation:

La regla de tres simple directa consiste en una relación de cantidades con proporcionalidad directa, que se da cuando dadas dos cantidades correspondientes son magnitudes directamente proporcionales. Esto es, si al multiplicar o dividir una de ellas por un número, la otra queda multiplicada o dividida por ese número.

La regla de tres simple permite hallar un cuarto término de una proporción conociendo los otros tres.

Siendo a, b y c datos conocidos y x la incógnita, la regla de tres simple se aplica de la siguiente manera:

a ⇒ b

c ⇒ x

Entonces: [tex]x=\frac{c*b}{a}[/tex]

A) En este caso la regla de tres simple se aplica de la siguiente manera: si en 3 paquetes hay 24 velitas, en 19 paquetes ¿Cuántas velitas habrá?

3 paquetes → 24 velitas

19 paquetes → x

Entonces [tex]x=\frac{19 paquetes*24 velitas}{3 paquetes}[/tex]

x= 152 velitas

En 19 paquetes habrá 152 velitas.

B) En este caso la regla de tres simple se aplica de la siguiente manera: si hay 24 velitas en 3 paquetes, hay 320 velitas ¿Cuántos paquetes se podrán armar?

24 velitas → 3 paquetes

320 velitas → x

Entonces [tex]x=\frac{320 velitas*3 paquetes}{24 velitas}[/tex]

x= 40 paquetes

Se podrían armar 40 paquetes iguales con 320 velitas.

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

HELP ASAP!!draw dotted lines to show the parallelogram or rectangle that can be used to find the area of each triangle then find the area of each triangle​

Answers

Answer:

The rectangle that we could use to find the area of the yellow triangle, is a rectangle of length = 12cm and a width = 8 cm. (A image of this can be seen below).

Remember that:

The area of a rectangle of length L and width W is:

A = W*L

The area of a triangle rectangle with catheti a and b is:

A = a*b/2

Then the area of the rectangle of length = 12cm and width = 8cm is:

A = 12cm*8cm = 96 cm^2

Now we need to subtract twice the area of a triangle rectangle of catheti a = 8cm and  b = 6cm

(one cathetus is 6cm because is exactly half of the length of the rectangle)

The area of each one of these triangle rectangles is:

A' = 8cm*6cm/2 = 24cm^2

The area of the yellow triangle will be:

A = A - A' = 96cm^2 - 2*24cm^2 = 48cm^2
