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.

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%  

Solve for x:
x - 6 = - 3x + 22
Plz I need this answer

Answers

Answer:

Your Answer is 7

Step-by-step explanation:

Very Simple!

x-6 = -3x + 22

Move the 6 over to the other side by adding 6 to both sides

x = -3x + 28

add 3x to both sides!

4x = 28

Divide by 4!

x = 28/4

x = 7!

Answer:

x=7

Step-by-step explanation

x-6 = -3x +22

 +6         +6

x          =        -3x +28

¿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

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 3}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{ - 4x + 1 = 2x - 17}[/tex]

Move 2x to left hand side and change it's sign

Similarly, move 1 to right hand side and change it's sign

[tex] \dashrightarrow{ \sf{ - 4x - 2x = - 17 - 1}}[/tex]

Collect like terms

The negative integers are always added but posses the negative ( - ) sign

[tex] \dashrightarrow{ \sf{ - 6x = - 18}}[/tex]

Divide both sides by -6

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°

Suppose you are deciding whether to take a train or a car to travel 3,000 miles across a country. The train travels at 95 kilometers an hour, while a car will travel 65 miles per hour on average. Which mode of transportation will take less time? Note that 1 mi=1.6 km.

Answers

Answer:

The car

Step-by-step explanation:

Train:

1mi = 1.6 km

95km = 95/1.6 = 59.375 km

95km/h = 59.375mi//h

Car

     65mi/h

Comparative:

65 > 59.375

then:

the car is more faster

Answer:

The answer is A : the car will take less time because it travels at a faster speed. the train will travel at 95/1.6=59.03 while the car travels at 65
