You get a 15% raise at your job and now make $13.50 per hour. What was you previous rate of pay per hour?

Anestetic [448]

You currently make $13.50 an hour. You've earned a 15% pay raise. You want to find out your previous rate of pay per hour.

<h2>Steps:</h2>

1.) Convert 15% to a decimal, which equals 0.15

2.) Multiply your current earnings with the percentage in decimal form (0.15)

$13.50 (current pay per hour) x 0.15 (percentage in decimal form) = $2.025 (difference between your previous wage and your current wage)

3.) Subtract the difference of your previous wage and current wage with your current earnings

$13.50 (current pay per hour) - $2.025 (difference between previous and current wage) = $11.475 (previous pay per hour)

4.) Since this is talking about wage, rounding is not applicable. In other cases, your number would be rounded off to $11.48, however you can't add what you don't have, so you would have to round down.

<h2>You were previously making $11.47 an hour.</h2>

Please Help me!!!!!!!

Dafna11 [192]

Answer:

The equation of the boundary of the region is (x+2)² + (y-1)² = 25

Step-by-step explanation:

The satellite is positioned at (-2,1) and can sense the presence within 5 miles of its position.

The boundary of the region is a circle with center (-2,1) and radius 5.

The equation of the circle with center (h,k) and radius r is given by

(x-h)²+(y-k)²=r²

The equation of the circle with center (-2,1) and radius 5 is given by

(x+2)²+(y-1)²=5²=25

(x+2)² + (y-1)² = 25 is the required equation of the boundary of the region.

Find the sum of all multiples of 4 between 25 and 100

Mademuasel [1]

Answer:

Sum of all multiples of 4 between 25 and 100 is 1116.

Step-by-step explanation:

Multiples of 4 between 25 and 100 = 28,32,36,40..............,96

let's check the series whether it is an arithmetic progression

a1 = 28 , a2 = 32 , a3 = 36 , a4 = 40

Common difference (d)=a2-a1=32-28 = 4

=a3-a2=36-32 = 4

=a4-a3=40-36 = 4

Common difference exists then the series of numbers is an Arithmetic progression.

To find number of terms :

a(a1) = 28 , d = 4 , l( last term ) = 96

l = a + (n-1)d

96 = 28 + (n-1)4

96 - 28 = (n-1)4

68 = (n-1)4

68/4 = (n-1)

17 = n - 1

17 + 1 = n

18 = n

Sum of all terms:

a = 28 , d = 4 , n = 18 , l = 96

Sn = n/2 ( a + l )

S18 = 18 / 2 (28 + 96)

S18 = 9 (124)

S18 = 1116

Therefore,Sum of all multiples of 4 between 25 and 100 is 1116.

NOTE:

Here 100 is also a multiple of 4 but question is asked between 25 and 100 so 100 is not considered in multiples.

For the function y = 7 − 3x, what is the ordered pair for x = 5?

Lemur [1.5K]

9514 1404 393

Answer:

(x, y) = (5, -8)

Step-by-step explanation:

The value of y is found by evaluating the equation for x=5.

y = 7 -3(5) = 7 -15 = -8

For x = 5, y = -8. As an ordered pair, this is (x, y) = (5, -8).
