mario earned a raise that increased his hourly pay rate from $8 to $10 what was the percent increase in marios hourly pay rate

Answers

Answer 1

Answer:

25%

Step-by-step explanation:

Initial hourly pay of Mario = $8

Current hourly pay of Mario = $10

Increment = current hourly pay - initial hourly pay = $10-$8 = $2

% increase in hourly pay rate = increment/initial pay × 100$

℅ increase = $2/$8×100%

% increase = 1/4×100%

%increase = 25%

Therefore, percent increase in marios hourly pay rate is 25%

Which equation has no solution?|4x – 2| = –6
|–2 – x| = 9
|3x + 6| = 6
|–2x + 8| = 0

Answers

Answer:

Option A) |4x - 2| = - 6 has no solution.

Step-by-step explanation:

option A) |4x - 2| = - 6

Since left hand side of function is in modulus, so it will always gives positive values but right hand side is - 6 ,

So, there are no values of x that make the equation true.

option B) |- 2 - x| = 9

Equation is true for x = 7

option C) |3x + 6| = 6

Equation is true for x = 0

option D) |–2x + 8| = 0

Equation is true for x = 4.

hence, option A) |4x - 2| = - 6 has no solution.

Answer:

Option 1

there are no values of x that make the equation true

Why is 3 to the power 0 = 1

Answers

When we raise something to a power, it really justs means we are multiplying it by itself. 3^2 (3 to the power of 2) means that we are mutliplying 3 by itself: 3•3 = 9 or 3^2 = 9 (there are two 3's)

However, when we rasie something to the 0 power, it equals 1. That is because we are multiplying it by itself 0 times. We are not multiplying it by zero, we are effectively doing nothing at all. 3^0 = 1

Answer:

90, 90, 90, 135, 135

Step-by-step explanation:

The sum of the measures of all angles is 540 deg.

The measures of the angles are: x - 45, x - 45, x, x, x - 45.

Add the expressions of the measures of the angles and set equal to the sum of the measures, 540 deg. Then solve for x. Then use the value of x to find each angle measure.

x + x + x - 45 + x - 45 + x - 45 = 540

5x - 135 = 540

5x = 675

x = 135

x - 45 = 135 - 45 = 90

Answer: 90, 90, 90, 135, 135
