3 is what I think the answer would be. 3 + 1 is 4, 4 is not a prime number, 3 is prime.

Answer:  The required example is x = 5.

Step-by-step explanation:  Given that if x is a prime nu mber, then x+1 is not a prime number.

We are to give a counterexample for this.

Let us consider that

x=5.

Then, we know that x is a prime number.

But, we get

x+1=5+1=6, which is not a prime number.

Thus, the required example is x = 5.

An equal mass of silver will displace a different volume of fluid than that displaced by gold.

<h2>Archimedes principle</h2>

According to the Archimedes principle, when an object is partially or completely immersed in water, the object will experience a force that displaces its own weight of fluid.

Therefore, when the jeweler deceptively replaced “an equal weight” (or equal mass) of gold with silver, we can know that by observing the volume of water displaced in each case. An equal mass of silver will displace a different volume of fluid than that displaced by gold.

a cone with radius of 3 feet and a height of 5 feet is placed on top of a cylinder as shown find the volume of the total figure
Darina [25.2K]

Answer: Volume of the cone = 47.12 cubic feet.

Step-by-step explanation:

You didn't finish the question so Idid the best with what I had, you also didn't include the image that I think was supposed to be included.

To solve for the full volume including the cylinder, use the cylinder's volume formula.

Volume of a cylinder = height (pi) (r^2) and then add it to the 47.12.

Volume of a cone is pi(r^2)(h/3)

plug and chug!

h stands for height and r stands for radius.

Find the slope and the y -intercept of the line.
Eduardwww [97]

Answer:

The slope is: 3

The y-intercept is: \frac{2}{3} or 0.66

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

To write the given equation in this form, we need to solve for "y":

9x - 3y = -2\\\\- 3y = -9x-2\\\\y=3x+\frac{2}{3}

Therefore, you can identify that the slope of this line is:

m=3

And the y-intercept is:

b=\frac{2}{3}=0.66

How many feet are in 84 inches
Drupady [299]
Since there are 12 inches in 1 foot you have to divide 84 by 12

84 divided by 12 is 7

So, there are 7 feet in 84 inches
