We know that there are 16 girls. That is the first part of the ratio. Now, it says girls to students, which mean you have to add up the total of girls and boys together. 12+16=28. There are 28 students in total. Now, you have the ratio of 16:28. But, it says simplified...so we need to divide both sides of the ratio by a number. Let's choose 4 because 4 can go both into 16 and 28. 16/4=4. 28/4=7. So, the simplified ratio of girls to students in the classroom is 4:7.
Hope this helped!
There's a catch here, and I don't really want to go into full detail. Because of
this catch, I think it would be unusually tough to write a simple equation for this
situation. If you wouldn't mind, let's just list it instead:
<u>After</u> . . <u>water added</u> . . <u>total in pool</u>
7 min . . . 14 gallons . . . 14 gallons
1 more . . 1 gallon . . . . . 15 gallons
7 more . . 14 gallons . . . 29 gallons
1 more . . 1 gallon . . . . . 30 gallons
5 more . . 10 gallons . . . 40 gallons, the pool is full
Add up all the minutes: <u>21 minutes</u>
Answer:
m = 3.53972077085
Step-by-step explanation:
-3 ×
- 3 = -27
Subtracting -3 from both sides of the equation gives;
-3 ×
= -24
Dividing by -3 on both sides of the equation gives;
= 8
Let 2m - 5 = x
xloge = 3log2
x =
= 2.0794415417
So,
2m - 5 = 2.0794415417
2m = 2.0794415417 + 5
2m = 7.0794415417
Dividing by 2 on both sides of the equation gives:
m = 3.53972077085
