Answer:

True

Step-by-step explanation:

The equation of direct variation is

y = kx ← k is the constant of variation

To find k divide both sides by x

\frac{y}{x} = k

That is the constant is the ratio of y- values to x- values

A penguin walks 10 feet in 6 seconds. At this speed:
Leya [2.2K]

The penguin will walk 75.15 feet in 45 sec

It will take the penguin 26.95 sec to walk 45 feet

Step-by-step explanation:

Given

Distance = d = 10 feet

Time = t = 6 sec

First of all we have to calculate speed

Let s be the speed, then

s=\frac{d}{t}\\=\frac{10}{6}\\=1.67\ ft\ per\ sec

Now,

How far does the penguin walk in 45 seconds?

Here we know the speed and the time

So,

s=1.67 ft per sec

t = 45 sec

So,

s=\frac{d}{t}\\1.67=\frac{d}{45}\\1.67*45=d\\d=75.15\ feet

How long does it take the penguin to walk 45 feet?

Here we know

d =45 feet

and

Speed =s =1.67 ft per sec

So,

s=\frac{d}{t}\\1.67=\frac{45}{t}\\t=\frac{45}{1.67}\\t=26.95\ sec

The penguin will walk 75.15 feet in 45 sec

It will take the penguin 26.95 sec to walk 45 feet

Sue graphed the formula for converting temperatures from Fahrenheit to Celsius. If the temperature is 50 degrees Fahrenheit, wha
KATRIN_1 [288]

Answer:

Second Option (10° Celsius)

Step-by-step explanation:

There is a formula to convert the temperature which is in degree Celsius into degree Fahrenheit and vice versa. The formula to convert the temperature in degree Fahrenheit into degree Celsius is:

C° = (F° - 32) * 5/9.

It is given that the temperature is 50° Fahrenheit. Therefore, F° = 50°. Substituting F° = 50° in the formula gives:

C° = (50° - 32) * 5/9.

Further simplification results in:

C° = 18 * 5/9. Therefore, C° = 10°.

So the correct answer is 10° Celsius!!!
