Answer:

The Archimedes Principle

Step-by-step explanation: He took the 5 kg crown and dipped it in a vessel full of water. He calculated the displaced water.

Then he took 5 kg pure gold bricks and dipped it in a vessel full of water. He then calculated the displaced water and he found that the vessel with pure gold bricks displaced more water than the vessel with the crown. This is the Archimedes principle which states that the body at rest in a fluid is acted upon by a force pushing upward called the buoyant force, which is equal to the weight of the fluid that the body displaces.

Hope it helps you:))))

Have a good day

Susan has a rectangular fence around her swimming pool. The fence she built was 15 ft long, 10 ft wide and 6ft tall. How many sq
Dmitriy789 [7]

Answer:

300 Square feet

Step-by-step explanation:

Susan built a rectangular fence around her swimming pool.

Length=15ft

Width(or Breadth)=10ft

Height=6ft

To solve this, picture a cuboid with the top and bottom open, that is the key to finding the Surface Area of the Fence.

Surface Area of a Cuboid= 2(LW+LH+WH)

However since the top and bottom are open, the Surface Area becomes

Surface Area of the fence= 2(LW+WH)

                                       =2((15X6)+(10X6)

                                       =2(90+60)=2 X 150 =300

Susan uses 300 Square feet to build her fence.

Alexa and Samantha work at a furniture store. Alexa is paid $250 per week plus 9.5% of her total sales in dollars, xx, which can
8_murik_8 [283]

Answer:

As per the statement:

Here, x represents the total sales in dollars

Total weekly pay of Alexa in dollar is represented by:

g(x) = 250+0.095x        

and

Total weekly pay of Samantha in dollar is represented by:

f(x) = 413+0.085x      

We have to find the value of x, in dollars that will make their weekly pay the same.

⇒g(x)=f(x)

Substitute the values we have;

250+0.095x = 413+0.085x

Subtract 250 from both sides we get;

0.095x =163+0.085x

Subtract 0.085 x from both sides we get;

0.01x =163

Divide both sides by 0.01 we have;

x = \frac{163}{0.01}

Simplify:

x = $16300

Therefore, $16300 that will make their weekly pay the same
