So, I'm just going to go ahead and answer this question (Even though the question isn't quite defined):
Assuming that we want to know his usual pay, we can represent his pay with the variable 'p':
32p + 4(1.3p) = 531.96
32p + 5.2p = 531.96
37.2p = 531.96
p = 14.3
Knowing this, we can multiply his usual pay by 1.3 to find his overtime pay:
14.3 * 1.3 = 18.59
Julio's normal pay is $14.30 an hour, and his pay after 32 hours of workingis $18.59.
If this wasn't the answer you were looking for, tell me and I'll fix it.
Have a nice one!
First Question
circumference = pi * diameter
diameter = circumference/pi = 94.2 in./3.14 = 30 in.
The wheels have a 30-inch diameter.
-----------------------------------------------------------------------
Second question
The area of a circle: area = pi * r^2
radius = diameter/2 = 94.2 in./2 = 47.1 in.
area = pi * r^2 = 3.14 * 47.1 in. * 47.1 in. = 6966 in.^2
Answer: 6966 in.^2
-----------------------------------------------------------------------
Third question
The piece of felt has a width equal to the diameter of the wheel. The length has to be the same as 4 diameters.
4 * 94.2 in. = 376.8 in.
Answer: 376.8 in.
X(-x^4)(-x^4)=
The answer is x^9
Answer:
147
Step-by-step explanation:
The ∑ symbol means sum the term inside 4n + 1 from n = 2 to n = 8
Substitute n = 2, 3, 4, 5, 6, 7, 8 into the expression and sum the results , that is
4(2) + 1 + 4(3) + 1 + 4(4) + 1 + 4(5) + 1 + 4(6) + 1 + 4(7) + 1 + 4(8) + 1
= 9 + 13 + 17 + 21 + 25 + 29 + 33
= 147
