Answer:
$4.38
Step-by-step explanation:
First, we need to find out how much the item costs with the sales tax. 4.5% is also equal to 0.045. We can multiply 14.95 by 0.045 to get the sales tax. This would end up to be 0.67275 which we can round to 0.67. We can now add 0.67 to 14.95 to get $15.62. Since we gave the cashier a $20 bill we need to subtract 20 by 15.62 to get $4.38.
Answer:
La máquina llenó:
6 baldes
Step-by-step explanation:
Por regla de tres:
4 baldes son a 30 minutos
M baldes son a 45 minutos
M = 45*4/30
M = 180/30
M = 6
25^(n-3)=5^(n+8)
Remember: 25=5²
Therefore:
5^[(n-3)²]=5^(n+8)
5^(2n-6)=5^(n+8)
Then:
2n-6=n+8
2n-n=8+6
n=14
Answer: n=14

If you use the SAS theorem, you can prove the triangles are congruent. Due to vertical angles, we have one angle, and we know one side is congruent. In order to prove these triangles are simillar, we need another side
