Answer:

520

Step-by-step explanation:

This problem is

boys + girls = total

Boys = 442

Girls = 15% of the total

Therefore, substituting in, gives us:

442 + .15t = t, where t is total

Then 442 = .85t and

t = 520

Remark

Watch out for the -4<=x<=6 thing. It causes lot's of problems if you are not careful.

Solution.

The second best answer is A and if that restriction, -4<=x<=6, wasn't there, the answer would be A.

When y = - 4, the x value falls outside the restricted domain ( -4<=x<=6) we have been given. so B is not the answer.

When x = - 4 you have to read straight down to see what the y value is. It is - 2. So this is your answer. Only exactly what is the answer. They ask for the minimum value and that is a y value in this case.

So the answer is C <<<<< Answer.

When y = 1 , x = - 2 1/2. That is within the domain, but it is not the minimum value so D is wrong.

<h2>Answer:</h2>

Driver experiences 17.68 G's on an average.

<h2>Step-by-step explanation:</h2>

In the question,

We know that in a car crash the speed of the car goes from the speed of 26 m/s to 0 m/s in 0.15 seconds.

So,

The final speed, v = 0 m/s

Initial speed, u = 26 m/s

Also,

Time in seconds, t = 0.15 s

So,

Using the equation of law of the motion, we get,

v = u + at

0 = 26 + a(0.15)

a = -26/0.15

a = -173.33 m/s²

As, there is deceleration of the car is taking place the acceleration is in negative.

Now,

To convert it into the force in the G's we need to divide the deceleration by the acceleration (gravity), g.

So,

G's experienced by the driver on an average is given by,

$\frac{173.33}{9.8}=17.68$

Therefore, on an average the driver experiences 17.68 G's.

You don’t have enough sugar because you only have 1 2/15 pounds of sugar. 1 2/15 is less than 1 1/2.
