We know that
<span>A pitcher of water contains 1/4 liters of water--------------> 0.25 lt
then
0.25 lt/5--------> 0.05 lt
In each glass are 0.05 lt of water
1 lt-------------> 1000 ml
0.05 lt----------> X
X=0.05*1000--------> X=50 ml
the answer is
</span>In each glass are 0.05 lt of water
In each glass are 50 ml of water<span>
</span>
Answer:
x power of 4
Step-by-step explanation:
Subtract 7 by 3
Answer: 208 calories.
Step-by-step explanation:
To find the answer, first find out the number of calories in one ounce of frozen yogurt:
= 78 / 3
= 26 calories
One ounce of frozen yogurt contains 26 calories.
If there are 8 ounces therefore, the number of calories would be:
= Yogurt * calories per yogurt ounce
= 8 * 26
= 208 calories.
I guess I can give a brief overview and then you can decide if I should go deeper into these meaning and use.
Complex numbers are useful because in a lot of cases we need to use the square root of a negative number. Ex.
Solve the quadratic equation x^2+x+1=0
We have to use the quadratic formula since its not factorable.
x=[-1+-sqrt(1-4*1*1)]/2
x=-1/2 + or - sqrt(-3)
If we don't have imaginary numbers, we would be stuck because sqrt(-3) wouldn't exist as you cannot take the square root of a negative number.
But with complex numbers we can actually get the answer for that equation as
x=-1/2 + or - sqrt3*i
Which would give us a mean of using this answer to calculate further to get other needs depending on the problem you are solving. If complex number is not a thing, about half of our equations will have undefined answers.
Now conjugates is a more interesting one, on the surface level we are discussing here there is not much its used for except if you have a complex number as a root of a quadratic equation, then the conjugate of that complex number must also be a solution. Again if you want me to go a more in depth just comment down below, because I could write an entire essay on this topic :-)
Answer:
Matthew payed .63 (rounded .625) cents for each toothbrush while Jon payed .72 cents per toothbrush
Step-by-step explanation:
$5 = 8 toothbrushes
$18 = 25 toothbrushes
5 / 8 = .625
18/25 = .72
