Answer:

1) El triángulo tiene un perímetro cuyo valor es 19 cm y un área de 14,92 cm²

2) La circunferencia tiene un perímetro cuyo valor es 14,14 cm y un área de 15,90 cm²

Step-by-step explanation:

El perímetro es una medida de la distancia alrededor de una figura y el área da una idea de qué tanta superficie cubre dicha figura.

Entonces, el perímetro es la medida obtenida como resultado de la suma de los lados de una figura geométrica plana. Es decir, el perímetro es lo que mide el contorno de la figura.

El área de un triángulo es igual a base por altura dividido por 2.

Siendo r el radio de la circunferencia, el perímetro será calculado como:

P=2*π*r

y el área será:

A=π*r²

1) En este caso, el perímetro es calculado como:

P= 6 cm + 8 cm + 5 cm= 19 cm

Y el área del triángulo es calculada como:

[tex]A=\frac{base*altura}{2} =\frac{8 cm*3.73 cm}{2}[/tex]

A= 14,92 cm²

El triángulo tiene un perímetro cuyo valor es 19 cm y un área de 14,92 cm²

2) Siendo el diámetro un segmento de recta que va desde un punto de la circunferencia a otro y pasa por el centro del círculo y l radio la distancia desde el centro del círculo hasta un punto de la circunferencia, entonces, el radio es la mitad del diámetro.

Siendo el diámetro de la circunferencia 4,5 cm, entonces el radio r tiene un valor de 2,25 cm.

Entonces el perímetro será calculado como:

P=2*π*2,25 cm

P= 14,14 cm

y el área será:

A=π*(2,25 cm)²

A= 15,90 cm²

La circunferencia tiene un perímetro cuyo valor es 14,14 cm y un área de 15,90 cm²

Answer: The greatest number of flowers that could be in a bouquet = 2

Step-by-step explanation:

Given: Sandy has 10 roses, 2 daisies, and 8 tulips.

Each bouquet has the same number of flowers and the same type of flower.

The greatest number of flowers that could be in a bouquet = GCD (10,2,8)

Since 10=2 x 5, 8 = 2 x 2 x 2

GCD (10,2,8) =2

Then, The greatest number of flowers that could be in a bouquet = 2

Answer:

an=a1+(n-1)*-6

Step-by-step explanation:

a1= 3

the recursive formula is an= a1+ (n-1)d

d= how you get from one to the other

to get from 3 to -18 you could either subtract 21 or multiply it by -6

to find which one you have to look at the next number which is 108

to get from -18 to 108 you would either add 126 or multiply it by -6

since multiplying by -6 is in both that is the answer

d= -6

an=a1+(n-1)*-6

Answer: 3/10

Step-by-step explanation:

Since the rest of the trees are pears trees and plum trees in the ratio of 7:5 and there are 175 plum trees, the number of pear trees will be:

= 175 ÷ 5/7

= 175 × 7/5

= 245

Plum trees = 175

Pear trees = 245

Apple trees = 600 - (175 + 245)

= 600 - 420

= 180

Fraction of apple trees = Number of apple trees / Total number of trees

= 180/600

= 3/10

Answer:

36.008 or 36

Step-by-step explanation:

Use the equation for the length of any circular arc  

s = r(radians)  

s - length of a circular arc

r - radius  

radians - radian measure of the central angle  

Then, set-up the equation:  

s = r(radians)

70.7m = r(5pi/4)  

Get variable "r" on one side by multiplying both sides by 4/5pi, which should result in the following:  

r = 70.7m x 4/5pi  

then solve for r  

r = 282.8/5pi = 18.004  

The radius is half the diameter therefore just multiply the radius by 2  

d = 18.004 x 2  

= 36.008 or 36  

The diameter of the circle is 36 meters.

The arc is a portion of the circumference of a circle.

We have been given that an arc is 70.7 meters long and is intercepted by a central angle of 5π/4 radians.

We have to determine the diameter of the circle

For the length of the circular arc, use the equation.

⇒ 70.7 m = R(5π/4)  

Multiply both sides by 4/5π to get the variable "R" on one side, which should get the following:

⇒ R  = 70.7 m × 4/5π

⇒ R = 282.8/5π

∵ π = 3.14

⇒ R = 282.8/5(3.14)

⇒ R = 18.004  

Since the radius is equivalent to half the diameter, simply double the radius by 2.  

⇒ D = 18.004 × 2  

⇒ D = 36.008 ≈ 36  

Hence, the diameter of the circle is 36 meters.

Answer:

y = 1.25x + 2

Step-by-step explanation:

Answer:

Step-by-step explanation:

( -4 , -3 ) ( 8 , 12 )

12 + 3   15 = 5

8 + 4    12 = 4

↑ slope = 5/4

↓ point slope form: y - y₁ = m ( x - x₁ )

y + 3 = 5/4 ( x + 4 )

y + 3 = 5/4x + 5

y = 5/4x + 2

Answer:

₹40000, 66.6%

Step-by-step explanation:

Given data

Number of boxes= 50

Cost per box= ₹1200

Total cost= 50*1200= ₹60000

Total number of mangoes in all 50 boxes= 50*100= 5000 mangoes

Cost price per mago= 60000/5000=  ₹12

Selling price per mango=  ₹20

profit = selling price- cost price

profit=  20-12

proft=  ₹8

Total profit = 8*5000

Total profit= ₹40000

%profit = 40000/60000*100

%profit= 0.666*100

%profit= 66.6%

Answer:

El camino diagonal debe medir 100 metros de largo.

Step-by-step explanation:

Podemos encontrar el camino usando Pitágoras:

[tex] D^{2} = L^{2} + A^{2} [/tex]

En donde:        

D: es el camino diagonal = hipotenusa

L: es el largo = 80 m = cateto

A: es el ancho = 60 m = cateto

Entonces, el camino diagonal es:

[tex] D = \sqrt{L^{2} + A^{2}} = \sqrt{(80 m)^{2} + (60 m)^{2}} = 100 m [/tex]

Por lo tanto, el camino diagonal debe medir 100 metros de largo.

Answer:

38 in^2 and 26 in^2

Step-by-step explanation:

1. The formula of the area of a trapezoid is [tex]A = \frac{1}{2} (b_{1} + b_{2})h[/tex] where b = base and h = height.

So, [tex]A = \frac{1}{2} (7+12)(4)[/tex] = 38 [tex]in^{2}[/tex]

2. [tex]A = \frac{1}{2}(5+8)(4)[/tex] = 26 [tex]in^{2}[/tex]

No, Betsy is not correct. She likely forgot to multiply by 1/2 when calculating the area. The correct answer is 26 inches squared.

Step-by-step explanation:

The distance between the tree and the rock formation is approximately 304.14 meters.

To find the distance between the tree (point T) and the rock formation (point R), we can use the law of cosines. The law of cosines relates the lengths of the sides of a triangle to the cosine of one of its angles.

Let's denote the unknown distance between the tree and the rock formation as 'd.'

We have a triangle with sides of lengths 200 meters (side ST), 150 meters (side SR), and d meters (side TR). The angle opposite side ST is 120 degrees.

According to the law of cosines:

d² = 200² + 150² - 2 * 200 * 150 * cos(120°)

Now, we can calculate this expression to find the value of d:

d² = 40000 + 22500 - 60000 * cos(120°)

Using the value of cos(120°) ≈ -0.5, we have:

d² = 40000 + 22500 - 60000 * (-0.5)

d² = 40000 + 22500 + 30000

d² = 92500

Taking the square root of both sides to solve for d:

d = √92500

d ≈ 304.14

Therefore, the distance between the tree and the rock formation is approximately 304.14 meters.

Answer:

The answer should be $3.125 or $3.13 rounded.

Step-by-step explanation:

First I divided 1.25 by 100 because 1 meter equals 100 centimeters.

1.25 ÷ 100 = 0.0125

Now that we know that it costs 0.0125 for 1 centimeter we multiply it by 250.

0.0125 * 250 = 3.125

Since it says to round to the nearest cent, the answer should be 3.13

Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.So the volume of the cube having side 15 mm is 3375 cubic inches.

Different Ways to Find Volume

Solve for Volume by Space. All physical objects occupy space, and you can find the volume for some of them by measuring their physical dimensions. ...

Solve for Volume by Density and Mass. Density is defined as an object's mass per a given unit of volume. ...

Answer: Michael's paycheque = $ 1704

Donald's paycheque =  $ 568

Jacob's paycheque = $ 648

Step-by-step explanation:

Let x = Michael's paycheque

Donald's paycheque = [tex]\dfrac13x[/tex]

Jacob's paycheque = [tex]\dfrac 13 x+80[/tex]

Together, the three friends earned $2920 in one week.

[tex]\Rightarrow\ x+\dfrac13x+\dfrac13 x+80=2920\Rightarrow\ (\dfrac{3+1+1}{3})x=2920-80\\\\\Rightarrow\ \dfrac{5}{3}x=2840\\\\\Rightarrow\ x=2840\times\dfrac{3}{5}\\\\\Rightarrow\ x=1704[/tex]

Michael's paycheque = $ 1704

Donald's paycheque = [tex]\dfrac{1704}{3}=\$ 568[/tex]

Jacob's paycheque = $ 568+80 = $ 648

Step-by-step explanation:

For the real estate agent: To find percent of a number, you can just divide by 100 and times it by the percent number, in this case it is 3.

$575,000 / 100 = $5,750

$5750 * 3 = $17,250

The agent earns $17,250.

For the computer store: Use the percentage and multiply it by 0.45, or whatever the percentage is.

150 * 0.45 = 67.5. This is the markup.

Now add the original value back to the markup.

150 + 67.5 = 217.5. This is the selling price of the computer.

For the video game: Use the percentage and multiply it by 0.25, or whatever the percentage is.

$55 * 0.25 = $13.75. This is the discount.

Now subtract the discount from the first value.

$55 - $13.75 = $41.25. This is the sale price.
