Sydney currently earns 11.50 an hour working part time. What is the minimum increase per hour she needs to at least match the av
nlexa [21]

Answer:

The salary of Sydney to meet the loss due to inflation should be 11.85 per hour

Step-by-step explanation:

The inflation rate is 3%

This means that the alary amount will reduce by 3%.

3% of Sydney's hourly salary is

\frac{3}{100} *11.50 = 0.345

Hence, the new salary must increase by 0.345 dollar per hour

The salary of Sydney to meet the loss due to inflation should be 11.50 + 0.345 = 11.845 or 11.85

40 points! Find the distance UV between the points U (2,-2) and V (-5, -3). Round your answer to the nearest tenth, if necessary
ollegr [7]
  • U(2,-2)
  • V(-5,-3)

\\ \sf\longmapsto UV=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

\\ \sf\longmapsto UV=\sqrt{(-5-2)^2+(-3+2)^2}

\\ \sf\longmapsto UV=\sqrt{(-7)^2+(-1)^2}

\\ \sf\longmapsto UV=\sqrt{49+1}

\\ \sf\longmapsto UV=50

The sum of five consecutive integers equals 5.5 times the middle integer. Find the integers.
weqwewe [10]

The integers are therefore -2, -2, 0, 1 and 2

<h3>Linear equation</h3>

Let the five consecutive integers be x-3, x-2, x-1, x and x+1

If the  sum of five consecutive integers equals 5.5 times the middle integer, then;

x-3+x-2+x-1+x+x+1 = 5.5(x-1)

5x - 5 = 5.5x - 5.5

Collect the like terms

5x-5.5x = -5.5 + 5

-0.5x = -0.5

x = 1

The integers are therefore -2, -2, 0, 1 and 2
