Debora [2.8K]3 years ago
7 0

Answer:

Step-by-step explanation:

If I remember expanded form is putting all number in terms of being times 10 to a power.  starting with the ones place it's x10^0 which of course is just 1, so you don't need to include the x10 at all.

now, moving one either way  that 0 either  get 1 added to it or subtracted.  So in the 10s place it becomes x10^1 and the tenths place becomes x10^-1.  Similarly the hundreds place and hundreths place will have x10^2 and x10^-2 respectively.  So keep this pattern going to find each place of the number.  Can you list out what places are displayed in 5.625?

I will get you started, but let me know if you don't quite get it.  

5 + 6*10^-1 + ...

Can you figure out the rest?

What percent of 146 is 39​
marissa [1.9K]

Answer:

<em>39 is 26.71% of 146</em>

Step-by-step explanation:

Percentage solution with steps:

Step 1: We make the assumption that 146 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100% = 146.

Step 4: In the same vein, x% = 39.

Step 5: This gives us a pair of simple equations:

100% = 146(1).

x%=39(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS (left hand side) of both equations have the same unit (%); we have

100/x% = 146/39

Step 7: Taking the inverse (or reciprocal) of both sides yields

x% / 100% = 39/146    ⇒ x= 26.71%

Therefore, 39 is 26.71% of 146.

The potential energy of an object varies jointly with the mass of the object and the height of the object off the ground. A 25-k
xxMikexx [17]

Answer:

This is physics. By the way look the explanation.

Step-by-step explanation:

The formula of Potential Energy is E=mgh, where m is the mass of the object, g the gravitational, and h the height of the object. Given that the potential energy of the object is 150 Joules at 3 meters height, Represent m=E/(g*h), considering g=9.8 m/s^2(Because this value was used for the first object), we get m=150/9.8/3=5.102

Rounding to 2 decimals` 5.10 kg
