To pay the workers for the first 40 hours, it would be $1,450. To pay the workers in the 20 hour over time pay, it would be $1,088. This is $2,538, or $507.60 each.
Answer:
Step-by-step explanation:
Distributive property: a(b +c) =(a*b) + a*c
12(7n - 4) =12*7n - 12*4
= 84n - 48
Answer:
She has 23 nickles and 5 dimes.
Step-by-step explanation:
Let n = the number of nickles and d = the number of dimes.
The number of each = 28. Set up the equation:
n + d = 28
Solve for n:
n = 28 - d
The total amount is $1.65 or 165 cents:
5n + 10d = 165
Substitute:
5(28 - d) + 10d = 165
140 - 5d + 10d = 165
140 + 5d = 165
5d = 165 - 140
5d = 25
d = 5, the number of dimes.
Solve for n:
n = 28 - d
n = 28 - 5 = 23, the number of nickles.
Proof:
5n + 10d = 165
5(23) + 10(5) = 165
115 + 50 = 165
165 = 165

Answer:
- 7.6
- subtract the midline from the peak value
Step-by-step explanation:
The amplitude is the difference between the peak value (3.8) and the midline (-3.8). You find it by subtracting the midline from the peak:
amplitude = 3.8 -(-3.8)
amplitude = 7.6
Answer:
represents the lateral surface area of the cone.
Step-by-step explanation:
Lateral surface area of cone(L) is given by:
.....[1]
where,
r is the radius of the cone
l is the slant height of the cone.
As per the statement:
A right cone with radius r and slant height s.
⇒
Substitute in [1] we have;
Therefore, represents the lateral surface area of the cone.
