Let's find the required ratios first: to get to the relative percentages, we'll simply have to multiply by 100.
Since there are 16 girls, 10 boys and 9 adults, there are
people in total.
So, the ratio of girls is
The ratio of boys is
The ratio of adults is
B is correct.
because this number is around :
2.449489
hope this helps
So,
We are trying to figure out when Grandpa Lopez's age was twice that of Dad.
Let x represent the number of years before/after when G. Lopez's age was twice that of Dad.
66 + x = 2(37 + x)
Distribute.
66 + x = 74 + 2x
Subtract x from both sides.
66 = 74 + x
Subtract 74 from both sides.
-8 = x
So 8 years ago, G. Lopez was twice as old as Dad. Let's check that.
66 - 8 = 58
37 = 8 = 29
29 * 2 = 58
58 = 58
It checks.
The number of new cases be on Thursday after all of this growth and falling is 956.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
There are initially 800 cases, hence:
Number of cases on Monday = 1.15 * 800 = 920
Number of cases on Tuesday = 1.05 * 920 = 966
Number of cases on Wednesday = 0.9 * 966 = 869.4
Number of cases on Thursday = 1.1 * 869.4 = 956.34
The number of new cases be on Thursday after all of this growth and falling is 956.
