She has 2 $20 and 1 $10 bills.
Since it says that she has 1 more 20 dollar bill, we should subtract 50 by 20.
That gives us 30.
Then we should subtract it AGAIN, 30 by 20.
That gives us ten.
Finally, well subtract that, 10 by 10.
Equation:
[50-(20x2)]-10
Hope i helped!
Answer:men=152 women=76 children=38
Step-by-step explanation:
- men+women+children=266
- men=4*children
- women=2*childrens
- so let say x represent the numebers of children the equatin becomes: 4x+2x+x=266
- solve for x =38 so the numbers of children is 38
- men=4*38=152
- women=2*38=76
Answer:2,3,4
Step-by-step explanation:
Julie would reach her goal first. Julie would reach her goal in approximately 316 days while it would take Mary approximately 333 days to reach it.
I know this because the steps to solve the problem are:
1.) 1,000/12 = 83.333 (to find how many days it would take her everyday)
2.) 83.333x4 = 333 (multiplying the answer by four makes it every four days)
3.) determine that it takes Mary 333 days
4.) 1,000/19 = 52.631 (just like step 1 but with different numbers)
5.) 52.631x6 = 316 (just like in step 2 but different numbers)
6.) determine it takes Julie 316 days
7.) 316 < 333 (takes Julie less time)
The total cost for utilities last month is 353,571.43.
<h3>What is the total cost for utilities last month?</h3>
The total cost for utilities last month can be determined by multiplying the volume of the stadium by the cost per cubic foot.
The volume of the stadium can be determined by using the formula for the volume of a hemisphere.
Volume of a hemisphere = Volume of a hemisphere = (2/3) x (n) x (r^3)
n = 22/7
r = radius
2/3 x 22/7 x 150³ = 7071,428.57
The total cost for utilities last month = 7071,428.57 x 0.05 = 353,571.43
