Answer:
Step-by-step explanation:
A glass of <u>unsweetened lemonade weighs 255 grams. </u>A spoonful of sugar is weighed before it is stirred into the lemonade. The sugar weighs 25 grams. How much do you think the <u>sweetened lemonade will weigh after you stir in the sugar?</u>
<u></u>
<u>225 + 25 =</u> 250 grams
1 real solution means that it has a multiplicity aka
if r is the solution
0=(x-r)^m
theone that fits that is B, the solution is x=3
B is answer
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 17.16 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 17.16 is 100%, so we can write it down as 17.16 = 100%.
4. We know, that x is 62.4% of the output value, so we can write it down as x=62.4%
5. Now we have two simple questions:
1) 17.16 = 100%
2) x=62.4%
Where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
17.16÷x=100%÷62.4%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 62.4% of 17.16
17.16÷x=100/62.4%
(17.16÷x)×x=(100÷62.4%)×x
17.16=1.60256410256×x
(1.60256410256) to get x
17.16÷1.60256410256=x
10.70784=x
x=10.70784
Now we have:
62.4% of 17.16=10.70784
So 10.70784 is your answer
Hope this helps :)
