Answer 2

Answer:

x = 19

Step-by-step explanation:

Since C is between B and D , then

BC + CD = BD , substitute values

8x + 13 + 12x - 73 = 320 , that is

20x - 60 = 320 ( add 60 to both sides )

20x = 380 ( divide both sides by 20 )

x = 19

Given that figure JKLMNWWXYZ. Find the value of y

Answers

Answer:

[tex] \boxed{\sf y = 6 \ cm} [/tex]

[tex] \boxed{\sf x = 25 \degree} [/tex]

Step-by-step explanation:

It is given that JKLMN [tex] \sim [/tex] VWXYZ

So, from this we can say that:

JK [tex] \sim [/tex] VW & ∠LMN [tex] \sim [/tex] ∠XYZ

i.e.

(2y - 8) cm = 4 cm & 4x° = 5(x - 5)°

Solving for y:

⇒2y - 8 = 4

Adding 8 to both sides:

⇒2y - 8 + 8 = 4 + 8

-8 + 8 = 0:

⇒2y = 4 + 8

4 + 8 = 12:

⇒2y = 12

Dividing both sides by 2:

⇒[tex] \sf \dfrac{2y}{2} = \dfrac{12}{2} [/tex]

[tex] \sf \dfrac{2}{2} = 1: [/tex]

⇒y = [tex] \sf \dfrac{12}{2} [/tex]

[tex] \sf \dfrac{12}{2} = 6: [/tex]

⇒y = 6 cm

Solving for x:

⇒4x° = 5(x - 5)°

Expanding right hand ride expression:

⇒4x° = 5x° - 25°

Adding 25° to both sides:

⇒4x° + 25° = 5x° - 25° + 25°

25° - 25° = 0°:

⇒4x° + 25° = 5x°

⇒5x° = 4x° + 25°

Substracting 4x° from both sides:

⇒5x° - 4x° = 4x° - 4x° + 25°

4x° - 4x° = 0°:

⇒5x° - 4x° = 25°

5x° - 4x° = x°:

⇒x° = 25°

Step-by-step explanation:

the no of girls (320-180)=140

a) ratio of no of boys and girls=180/140=9/7=9:7

b)ratio of boys and total pupil=180/320=9/16=9:16

c) ratio of the girls and pupils=140/320=7/16=7:16

Answer:

a) 9:7 (9 being the boys,7 being the girls)

b)9:16 (9 being boys, 16 being the total pupils)

c)7:16 (7 being girls, 16 being the total pupils)

Step-by-step explanation:

m<JKM = 151 degrees is the total angle combining m<1 and M<2

therefore, we subtract m<2 from m<JKM to find m<1

Here is the equation:

m<JKM = m<1 + m<2

151 = m<1 + 98 (substitute)

53 = m<1 (simplify the like term so we subtracted 98 on both sides)

¿Cuál es el valor de 0.1561 redondeado a la décima más cercana?
A 0.15
B 0.16
C 0.1
D 0.2

Answers

Answer: 0.2

Step-by-step explanation: Necesitamos ajustar la estimación de 0.1561 al décimo más cercano.

El número después del decimal es el número en el décimo lugar. Considere el número a un lado del lugar de las décimas y utilice el número para decidir si se reunirán o seguirán siendo el equivalente. Observe que el número a un lado del décimo lugar es mayor o equivalente a 5 o menos de 5. En el caso de que ese número sea más digno de mención o equivalente a 5, en ese punto el número se reunirá aún en la remota posibilidad de que ese número es menor de 5, en ese momento el número no se reunirá. Permanecerá igual.

Consideremos el número dado 0.1561

El número en el lugar de las décimas es 1

El número después del punto de las décimas es 5 (que es más prominente o equivalente a 5)

De esta manera, el número se reunirá en 0,2

The “Get Up” challenge set to Ciara’s song is a dance that takes about 15 seconds to perform. What percent of the full 4-minute-and-23-second song does the dance represent?

Answers

Answer:

5.70%

Step-by-step explanation:

It takes the time to perform on Ciara's song = 15 seconds

Total time given as 4 minutes 23 seconds ≈ (4×60) seconds + 23 seconds

                                                                      = 240 seconds + 23 seconds

                                                                      = 263 seconds

Percent of time taken to perform of the full time = [tex]\frac{\text{time taken to perform}}{\text{Total time}}\times 100[/tex]

                                                                                = [tex]\frac{15}{263}\times 100[/tex]

                                                                                = 5.70 %

Therefore, percent of the time taken for the performance on the full song will be 5.70%

The formula c = 2.54n can be used to convert a measurement of c centimeters to an equivalent measure of n inches. Henry is 170 cm tall. What is his height, in inches? Round your answer to the nearest tenth of an inch. 66.7 in. 66.8 in. 66.9 in. 67.0 in.

Answers

Answer:

66.9

Step-by-step explanation:

Answer:

[tex]\boxed {\tt 66.9 \ inches}[/tex]

Step-by-step explanation:

We are given the formula:

[tex]c=2.54n[/tex]

where [tex]c[/tex] is centimeters and [tex]n[/tex] is inches.

We know that Henry is 170 centimeters tall. Therefore, we can substitute 170 in for [tex]c[/tex]

[tex]170=2.54n[/tex]

We want to find out how tall Henry is, in inches. We must isolate the variable for inches, [tex]n[/tex], on one side of the equation.

[tex]n[/tex] is being multiplied by 2.54. The inverse of multiplication is division. Divide both sides of the equation by 2.54

[tex]\frac{170}{2.54} =\frac{2.54n}{2.54}[/tex]

[tex]\frac{170}{2.54}=n[/tex]

[tex]66.9291339=n[/tex]

Round to the nearest tenth. The 2 in the hundredth place tells us to leave the 9 in the tenth place.

[tex]66.9 \approx n[/tex]

[tex]n \approx 66.9 \ inches[/tex]

Henry is about 66.9 inches tall.
