Answer:
Missing Value Is 4 .
Step-by-step explanation:
According To The Question, We Have
- A model with 4rows*4squares & 4rows*7squares
Equation is 16+28 = X*(4+7)
Solve the above Equation, We get 44=X*11 ⇔ X=4
Answer:
Step-by-step explanation:
I'm sure by now you have learned the difference between mass and weight. Mass will never change regardless of where something is while weight changes depending upon the pull of gravity. If we want the mass, then we have to take the weight on Earth and divide by its pull of gravity. The equation for that will be
W = mg where W is the weight in Newtons, m is mass and g is gravity.
685 = m(9.8) so
m = 7.0 × 10¹ kg
Now that we know that mass, and also because we know that the mass is constant no matter where the astronaut is, we can find his weight on Jupiter.
W = (7.0 × 10¹)(25.9) so
W = 1800 N
The total number of fossils at the museum is 25. If you divide 15 by 60%, you get 25. To check to see if that makes sense, multiple 25 by 60% and you should get 15. By getting 15, you now have 60% of the total fossils at the museum, proving that the total amount of fossils is 25.
First one:
This is the commutative property of addition, which states that for two addends, the order of addends does not affect the value of the end result.
Second one:
This is the multiplicative identity property. It states that any number, when multiplied by 1, is equal to itself.
Third one:
This is the additive identity property, which states that any number, when added to 0, equals the same number.
Hope this helps!
