Kylie records the weights of 3 objects as shown below. Which 2 objects can she put on a pan balance to equal the weight of a 460 gram bag? Show how you know.

The question is not complete, so i have attached the complete question.

The two objects she can put are the paper back and the bar of soap.

Explanation:

From the attached image, we can see that the 3 weights are;

Paperback Book : 343 grams

Banana: 108 grams

Bar of soap: 117 grams

Now, she wants to find which 2 objects she can put on a pan balance to equal the weight of a 460 gram bag.

Now, to get this, 2 of the given objects when added together has to give 460 grams.

Let's add the weight of the paper book and Bar of soap. This gives;

343 + 117 = 460 grams

Adding any other combination of two of the given weights wouldn't give 460 grams.

Thus, the two objects she can put are the paper back and the bar of soap.

this is the answer , p = 1 + (1/10)x

step-by-step explanation:

we have,

at sea level pressure is 1 atmosphere (i.e at x =0, p0=1 atmosphere)

at depth 23 meters , pressure = 3.3 atmosphere

since the pressure increases at constant rate as the depth increases, so we can write a relation as:

p =p0 +   kx   , where p is the pressure  , p0 is the initial pressure, x is the depth and k is constant rate of increasing.

to find constant rate k, plug p = 3.3 , p0 = 1 and x= 23 meters

we get,

  3.3 = 1 + k * 23

k = 2.3 / 23   = 1/10

so we can write the function formula as:   p = 1 + (1/10)x
