Answer:
$9426.50
Step-by-step explanation:
let noel's salary = x, robert's salary = y and john's salary = z
y = x - 512.75 ..........(1)
z = 3y = 3(x - 512.75) = 3x - 1538.25 ...............(2)
x + y + z = 47645.25..........................(3)
substitute for y and z
x + (x - 512.75) + (3x - 1538.25) = 47645.25
x + x - 512.75 + 3x - 1538.25 = 47645.25
5x = 47645.75 + 512.75 + 1538.25
5x = 49696.25
divide both sides by 5
x = 9939.25 ..... noel's salary
to get robert's salary substitute x in equation 1
y = 9939.25 - 512.75 = 9426.50
y = $9426.50..... robert's salary
The correct answer for each is
a= 390.8
b= 136.8
Answer:
The simple way to calculate a trade-weighted average tariff rate is to divide the total tariff revenue by the total value of imports. Since these data are regularly reported by many countries, this is a common way to report average tariffs.
Answer:
d(t) = -100t
Step-by-step explanation:
The general expression for the linear model is:
Since the submarine already starts at sea level, b=0:
The constant "m" is the rate at which the submarine descends in feet per minute. Considering depth as a negative quantity, m=-100
The linear model that represents the depth of the submarine relative to sea level, in feet, after t minutes is d(t) = -100t.
Answer:
x-17.5
Step-by-step explanation:
angles in a triangle add to 180
3x+8+(2x-3)+5x = 180
simplify(collect like terms):
10x + 5 = 180
solve:
10x = 175
x=17.5
