There are 14 male cousins and 10 female cousins.
Step-by-step explanation:
Let,
m be the male cousins and f be the female cousins
According to given statement;
m+f =24 Eqn 1
m= 2f - 6 Eqn 2
Putting value of m in Eqn 1
Dividing both sides by 3
Putting f=10 in Eqn 1
There are 14 male cousins and 10 female cousins.

Answer:
19 100 000
Step-by-step explanation:
The digit in the hundred thousands place is 0. The digit on its right is 5 and since the rule in rounding off states that if the digit beside the rounding digit is at least 5 or higher, round up by copying the digits at the left of the rounding digit, adding 1 to the rounding digit and replacing the digits after it to 0s.
Answer:
5.5 Hours
Step-by-step explanation:
Currently, the equation is 60=8.50h+13.25 and h stands for the hours that Sammie worked. So, you need to solve for h by first subtracting 13.25 (his tips) and getting the amount that he received for the hours that he worked.
You should now have 46.75=8.50h
Our final step, is to divide 46.75 by 8.50 to get h by itself and determine the total hours that Sammie worked.
In the end, you should come out with h=5.5, which means that Sammie worked 5.5 hours.
Answer:
132 cm
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi*r
Using 22/7 as pi
C = 2 * 22/7*21
= 132 cm
D. Because a number is irrational if it doesn't terminate or if it repeats over and over
