Answer:

x=60

Step-by-step explanation:

there is a law that says that the 124 angle and the unknown equation are equal, i just dont remember what that law is. but you can create the equation 124=2x+4 to solve for x, subtract 4 over and now you have 120=2x, divide by 2 and you will finish with 60=x

leave any questions in the comments and i will try to answer them, and if this helps, pls give brainliest pls.

Answer:4/13

Step-by-step explanation:

Number of yellow chicks = 8

Number of black and white chicks = 6

Total number of chicks = 8+6 = 14

The probability of the first yellow chick escaping will be 8 out of 14.

The probability of the second yellow chick escaping will be 7 out of 13 since there'll be 13 chicks left after the first yellow excaped.

Therefore, the probability that both chicks were yellow will be:

= 8/14 × 7/13

= 4/7 × 7/13

= 4/13

Therefore, the probability is 4/13.

Answer:

y = 85°

z = 35°

x = 60°

Step-by-step explanation:

y) 180 - 120 = 60, therefore:

180 - (35 + 60)

=> y = 85

z)

=> z = 35

x)

180 - (35 + 85)

=> x = 60

Hope this helps!

Answer:

to find y

you find the bottom right angle

which is 180-120 = 60

then you do 60+35 = 95

then 180 -95 because the sum of all angles in a triangle is 180

so the answer is 85 = y

There is a rule where the alternate angles between the parallel lines are identical

if y = 85 that means that the angle next to 35 is 85

same for angle z, if the top right 35, that means that angle z = 35

Now you add 35 + 85 = 120

180 - 120 = 60 = angle x

In summary

x=60

y=85

z=35

Hope that answers your question

Answer:

 [tex]\frac{2}{4} = 2 *\frac{1}{4} \\[/tex]

So the length of 2 of the 1/4 sections.

 [tex]\frac{5}{8} = 5* \frac{1}{8}[/tex]

So the length of 5 of the 1/8 sections.

Now,

[tex]\frac{2}{4} = x *\frac{5}{8}\\\\x = \frac{2}{4} * \frac{8}{5} = \frac{16}{20} = \frac{4}{5}[/tex]

Therefore 2/4 is 4/5 the length of 5/8.

Answer:

12cm

Step-by-step explanation:

The area of a kite is the product of the diagonals divided by 2:

A = (d1 * d2)/2

You can substitute what we have:

120 = (20 * d2)/2

And solve.

240 = 20 * d2

d2 = 12cm

The length of the other diagonal is 12cm.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

SOLUTION:

Step 1:

In this question, we are given the following:

The area of a kite is 120. One of the diagonals is 20.

What is the length of the other diagonal?

Step 2:

The details of the solution are as follows:

we know that,

The area of a kite is the product of the diagonals divided by 2:

A = (d1 * d2)/2

You can substitute what we have:

120 = (20 * d2)/2

And solve.

240 = 20 * d2

d2 = 12cm

CONCLUSION:

The length of the other diagonal = 12 cm.

Answer:

600 X (1.04)^15

$1080.57

Step-by-step explanation:

The formula for calculating future value:

FV = P (1 + r) n

FV = Future value  

P = Present value  

R = interest rate  

N = number of years

600 X (1.04)^15  = $1080.57

Answer:

Option B.

Step-by-step explanation:

For a function f(x), the domain is the set of all the possible values of x that can be used in the function.

We know that the natural logarithm is only defined for positive real numbers.

So, the function:

Ln(x + 2)

Works always that

x + 2 > 0

So we can just solve this inequality for x, and that will give us the domain of the function.

To isolate x, we just need to subtract 2 in both sides of the inequality.

x + 2 - 2 > 0 - 2

x > - 2

This is the domain of the function.

The correct option is B.

1: Igneous: Igneous rocks are formed by cooling magma. The location of the formation of the rock, as well as how fast the magma cools will determine the type of igneous rock.

2: Glassy and Metallic: Luster definition; the state or quality of shining by reflecting light; glitter, sparkle, sheen, or gloss: the luster of satin.

3: Minerals: The large mineral crystals in granite are evidence that it cooled slowly from molten rock material.

Answer:

Ana tiene 27 años mientras que Carlos, tiene 69 años

La suma de las edades es: 27+69 = 96

La suma de las cifras de este resultado es 9+6 = 15

Step-by-step explanation:

Vamos a hacer una linea temporal para ubicarnos en tiempo.

AÑO 2021, Ana tiene una edad A mientras que Carlos tiene una edad C

15 años para adelante

AÑO 2036, la edad de Carlos es el doble de la de Ana

C = 2A

Si nos vamos 6 años para atrás

AÑO 2015, la edad de Carlos es el triple de la de Ana

C = 3A

Como de 2015 a 2036 pasan 21 años, podemos plantear que

La edad de Carlos + 21  va a ser 2 veces la edad de Ana, traducido:

C + 21 = 2A, pero en 2015, ya sabemos que la edad de Carlos es el triple de la de Ana, entonces:

3A + 21 = 2A. Si despejamos:

3A - 2A = -21

A = |21|  Ésta es la edad de Ana. (Ponemos valor absoluto porque una edad no puede ir negativa.

Si Ana en 2014 tiene 21 años, Carlos tiene 63 (el triple) por lo que sumamos 6 años y llegamos al presente:

En 2021, Ana tiene 27 años (21+6), mientras que Carlos tiene 69 (63+6). Edades actuales.

Nos corremos 15 años al futuro, por lo que llegamos al año 2036.

Carlos pasa a tener 84 años (69+15) y Ana, 42 (27+15) donde verificamos que la edad de Carlos, es el doble que la de Ana, 84/42 = 2.

Finalmente la suma de las edades es: 27+69 = 96

La suma de las cifras de este resultado es 9+6 = 15

Given:

The data set is:

68, 74, 67, 72, 63, 70, 78, 64, 76

To find:

The median, first quartile, third quartile, and interquartile range of the data.

Solution:

We have,

68, 74, 67, 72, 63, 70, 78, 64, 76

Arrange the given data in ascending order.

63, 64, 67, 68, 70, 72, 74, 76, 78

Now divide the data in two equal parts.

(63, 64, 67, 68), 70, (72, 74, 76, 78)

So, the median of the given data set is 70.

Divide each parenthesis in two equal parts.

(63, 64), (67, 68), 70, (72, 74), (76, 78)

Now, the first quartile is:

[tex]Q_1=\dfrac{64+67}{2}[/tex]

[tex]Q_1=\dfrac{131}{2}[/tex]

[tex]Q_1=65.5[/tex]

The third quartile is:

[tex]Q_3=\dfrac{74+76}{2}[/tex]

[tex]Q_3=\dfrac{150}{2}[/tex]

[tex]Q_3=75[/tex]

The interquartile range (IQR) is the difference between third quartile and first quartile.

[tex]IQR=75-65.5[/tex]

[tex]IQR=9.5[/tex]

Therefore, median is 70, first quartile is 65.5, third quartile is 75 and the interquartile range is 9.5.
