$2.40 add all the values of the coins together
The answer is 5sqrt2 or 7.07
Since you have one 45 degree angle the other angle is also 45 degrees. This gives you a right isosceles triangle.
This can be solved using Pythagorean theorem or trig ratios.
a^2+a^2= 100
2a^2 = 100
a^2=50
a= sqrt 50
a=5sqrt2
First change 2/3 into a decimal: .67. Then divide 30 by .67: 44.77. Round it: 44.77 = 45. Each shirt was $45 :)
Answer:
A: E = 0.05t +56
B: $73.50
C: $60.05
Step-by-step explanation:
A) I'll just explain the equation in one go
Equation: E = 0.05t + 56
0.05 - This is meant to represent the 5% of tips
5% = 5/100
5/100 = 0.05
56 - This is a set value that has been established as a constant, thus it simply needs to be added to the 5%
B+C) Since we already have the equation set up, we just need to plug in the variable, t.
B) E = 0.05(350) + 56
= 17.5 + 56
= 73.50
C) E = 0.05(81) + 56
= 4.05 + 56
= 60.05
Hope that does something to help, even though this was posted a while ago
