Answer:
Step-by-step explanation:
Ratios can be of 2 types here:
Part to Part
and
Part to Whole
Part-to-Part ratios give the relationship between 2 distinct things/groups. Such as the ratio of male to female in a class, or ratio of water to sugar in a drink etc.
Part-to-Whole ratios give the relationship between one group/thing to the whole population. Such as the ratio of male to total students in a class, or the ratio of cups of sugar to total cups of drinks etc.
<u>Note:</u> If there are 2 parts in a population, we can essentially write 3 ratios. For example, the ratio of male to female in a class is 4 to 5. So in total there are 4+5 = 9 parts (whole). So we can say:
ratio of male to total population is 4 to 9
ratio of female to total population is 5 to 9
Also,
ratio of male to female (as stated before) is 4 to 5
3 ratios.
Set ? as x, and cross-multiply.
so x^2= 36
x = 6 or x = -6
Subtract 2 from each side of the equation, and
the answer will be right there, staring up at you.
Go ahead. It'll be very helpful for you.
Answer:
7 people went to the basketball game.
Step-by-step explanation:
Giving the following information:
They parked the car in a parking lot which charged $5. The cost per ticket was $24.
<u>To calculate the number of people, we need to use the following formula:</u>
Total cost (y)= x*24 + 5
173 = 24x + 5
168/24 = x
7 = x
7 people went to the basketball game.
It adds six every time so the answer is 56
