Answer:

54.846N

Step-by-step explanation:

Force = ?

Spring constant (K) = 188N/m

Spring stretch (x) = 0.292m

Force acting on a spring = spring constant * spring stretch

Force = 188 * 0.292

Force = 54.896N

The force acting on the spring is 54.896N

Answer:

The answer is 54.896N

Step-by-step explanation:

From Hooke's law,

Force = spring constant x extension

i.e

F = k x e

F = 188N/m x 0.292m

F = 54.896N

A scientist runs an experiment involving a culture of bacteria. She notices that the mass of the bacteria in the culture increas

Genrish500 [490]

The growth factor for the mass of bacteria is 2.8 in 1 week.

Step-by-step explanation:

Step 1:

It is given that the bacteria in the culture increase by 260% per week. Now we assign values to get a better understanding. If there were 1,000 bacteria in the culture at the start of the week there would be 1,000 + 260% at the week's end = 1,000 + 2,600 = 3,600 at the week's end.

Step 2:

To calculate the growth factor, we calculate the difference between the present value and the past value and divide it by the past value.

Here the past value is 1,000 and the present value is 2,600.

Growth factor = $\frac{difference in values}{past value} = \frac{3,600-1,000}{1000} = \frac{2,600}{1,000} = 2.6.$

So the growth factor is 2.6 per week.

What is the value of x in the equation 1/5 x - 2/3 y = 30 when y=15

zubka84 [21]

To determine the value of X in the given equation substitute the value of y into the equation and solve for x.

1/5x - 2/3y = 30
1/5x - 2/3(15) = 30
1/5x -10 = 30
1/5x - 10 + 10 = 30 + 10
1/5x = 40
1 = 5x • 40
1 = 200x
X = 1/200.

An hour before show time, only 266 people are seated for a movie. . According to ticket sales, 93% of the people have yet to

Mandarinka [93]

Answer:

3800 tickets

Step-by-step explanation:

we are given that,

total people seated:266

yet to come:93%

so the percentage of people who have arrived is 100%-93%=7%

and one ticket for each people

therefore,

$\displaystyle \begin{array}{ccc} \displaystyle \rm7\% \quad \text{People} \implies266 \: \text{tickets} \\ \displaystyle100 \%\: \quad \imath \imath \implies \frac{266}{7\%} \: \: \: \: \imath \imath \\ \\ \qquad \displaystyle \qquad\rm as \: \% = \frac{1}{100} \longleftarrow \frac{266}{ \dfrac{7}{100} } \\ \\ \displaystyle \rm \: by \: simplifying \: complex \: fraction\longleftarrow 266 \times \frac{100}{7} \\ \rm reduce \: fraction \longleftarrow 38 \times 100 \\ \rm simplify \:multiplication \longleftarrow3800\end{array}$

hence,

3800 tickets were sold for the movie
