Answer:
2400kJ
Step-by-step explanation:
Step one:
given data
power P= 400W
time = 10minutes
to seconds= 60*10 = 600 seconds
Required
the energy
Step two:
we know that Energy= power * time
E=P*t
E=400*600
E=240000
E=2400kJ
She converts 2400kJ into other forms
Answer:
1.125
Step-by-step explanation:
1) First you have to turn it into an improper fraction
8*1 = 8. Add the numerator--> 8+1 = 9.
2) The improper fraction is 9/8
3) Divide 9 by 8
**Write this using long division
8 goes into 9 one time, so we will write one as our first digit
Carry down the 1 and the 0, 8 goes into 10 1 times so write 1.
And this point we have 1.1 above
Carry down the 2 and the 0, 8 goes into 20 2 times so write 2
At this point we have 1.12
Carry down the 4 and the 0, 8 goes into 40 5 times with no remainders so write 5 and end the division process.
Now we have 1.125 as our decimal for 9/8 which is equivalent to 1 1/8.
This is the commutative property (of addition, but this applies to multiplication as well)
It doesn't matter which order the numbers are added in, the same result will be achieved.
1+2 = 2+1
2*4 = 4*2

Answer:
70/100.
Step-by-step explanation:
When adding fractions, you need to find a common denominator.
This just means that the numbers at the bottom of both fractions you are adding must be the same.
So for 19/100 + 1/10, you need to match the two denominators (bottom numbers).
To do this, you need to multiply 10 by 10 to get 100.
What you do to the bottom, you must always do to the top as well.
So multiply 7 by 10 and get 70.
70/100 will replace 7/10.
Now you can add fractions because the bottom numbers are the same.
